Just finished an 8 week 60,000 IU/week Vitamin D3 course (doctor prescribed). Now looking for a maintenance dose. thinking of switching to something like 2000 IU daily (saw this Briyo Vitamin D3 2000 IU).

Vitamin D3, A boost against POIS
Firstly I’d love to hear others testimonies. I didn’t want to make this post until I was fully healed (so im still healing but have extremely small symptoms after ejaculation), but my brain kept annoying me that people are suffering tell them what you found, if I wait a day more, someone could have missed this life saving information. My story: addicted to porn 13, tried quitting for years, got sicker, had a sort of rough family, mom would sometimes not cook food as punishment that really messed me up, at 18 I quit porn but had to leave university only did 1 semester and failed all courses (I was going crazy and POIS was hurting me a lot cause of nocturnal emissions). At 19 I quit pornography entirely, but my nocturnal emissions stayed, leaving me so sick, I could not eat etc… I got stomach issues, dry eyes and weird tastes, used to have cramps, loss of appetite, feeling extremely physically weak. it was easy to connect the dots since if I didn’t have the nocturnal emissions for 20 days I felt healthy enough to go to the park and in general healthy and motivated. Right now my symptoms have become quiet negligible after emissions. firstly I want to say, I actually have no need to ejaculate in the first place, my issue was I was stuck in a cycle of, nocturnal emissions and then becoming sick for the next 10-20 days, basically completely debilitated, my family helped me get through it. Heres the cure for a huge number of you, raise your vitamin D blood level MINIMUM to 46.6ng/l (USA) and for others countries 115nmol/L. Firstly you must go do a blood test and check your initial levels, it should be $30-$40, pretty cheap. Now to raise your Vitamin D blood level you must take a dose bigger than 5k, it really depends on your weight and activity (most of us sedentary for now). Don’t listen to the recommendation for around 2k or less, as I said at least 5000 IU of vitamin D3 drops! drops are better absorbed, and easy to take bigger doses. the vitamin D3 drops I take 3-4 from Walmart pretty pure ingredients, coconut oil and pure d3. Doctors found my Vitamin D level at 17nmol/L in USA that is like 6ng/ml, that is critically deficient and I won’t rage at the doctor now but doctors are not educated well it seems (especially standard family doctors or clinic doctors) on vitamin D, she told me take 2000 IU daily, I took that dose for around 1 year! and raised my level to only 57nmol/l or around 22ng/ml, that is still very low, there was no harm that when I I Italy found out my vitamin D is extremely low to take 10,000 IU d3, it’s passed now. But after that I basically got a single dose 200,000 IU D3 from an auntie, who came from Pakistan, in Canada you need to be prescribed big doses can’t get them (it is not dangerous, extremely hard to overdose on Vitamin D, like extremely extremely hard). Basically took the d3 200k ampoule and put it in milk and drank it, check after 2 weeks my blood levels at 128nmol/l or around 50ng/ml. I feel alot better, symptoms are disappearing had night falls and the symptom's I was able to brush away. it’s only been 2 weeks and my life is changing for the better, this is the best and most natural way to fix your issue. much love to you all. Don’t take 200,000 IU doses daily or anything like that, I took only a single dose and will take daily around 7,000 IU to 10,000 IU to maintain it (depends on your weight!). I’m 151lbs. I‘ll link a few videos explaining why the 600-800 IU doses recommended are so preposterous, but let me explain what Vitamin D is and how it works. Vitamin D, is actually just the sunshine vitamin, when a certain raise from the sunlight hits your skin (sunny day), your body is able to produce pre-Vitamin D, and then your body processes it (not tryna go into detail), at some point your body basically has Vitamin D3, this is not yet the active form, it is processed lastly by your kidneys to turn into its active form which is held by proteins. Doctors check 25 HydroxyVitamin D, which is basically one step before activated form. Your body needs all the forms though. Most doctors actually call Vitamin D a hormone not Vitamin because of how profoundly it effects your body and because it behaves like hormone especially it’s activated last form. Today people are at home or in buildings all day, it is common knowledge among doctors that Vitamin D deficiency is like an epidemic. and it’s making a lot of us sick, low mood depression, it’s linked to that too. How does this tie back to your POIS? Vitamin D controls immune modulation, turning on and off and not over reacting, majority of people with low Vitamin D develop allergy’s like peanut allergy, dust/pollen allergy’s, etc... Basically if you have low Vitamin D your immune system is tweaking. Majority of POIS as far as I know is allergy/ auto immune disorder, I’m just gonna cite studies so you can get the point. “Data from the HealthNuts study published in the Journal of Allergy and Clinical Immunologyindicates that infants with vitamin D deficiency face an 11.51 times higher risk of peanut allergy. This 2013 study, which evaluated 5,276 infants in Australia, found the association was specifically significant among children of Australian-born parents. For more details, visit PubMed.” 11 times, CAN YOU BELIEVE THAT cause I can! ”The VITAL study, a large-scale clinical trial published in The BMJ, found that adults taking 2,000 IU of Vitamin D3 daily had a 22% reductionin the rate of confirmed autoimmune diseases compared to those taking a placebo. The study, which followed over 25,000 participants for five years, suggests that Vitamin D helps regulate the immune system and may prevent the onset of conditions like rheumatoid arthritis and psoriasis, with the protective effects becoming even more significant after two years of consistent supplementation. You can view the full study summary and data on PubMed.” I just wanna mention they used 2000IU which is low and basically like nothing, which means the real percentage is way higher than 22% reduction in auto immune disorder development. now why do I call it preposterous that giving anything below 5,000 IU is way to low, well I’ll explain then link 2 doctor videos. We get Vitamim D from the sun, and hoenst that’s the best thing, if you think you can sun bath, then that will literally be better and good enough then taking any D3 oil drops, because it’s the natural way of your body. “Full-body exposure to peak midday sun until the skin begins to turn slightly pink—known as one Minimal Erythemal Dose (MED)—can trigger the production of 10,000 to 25,000 IU of Vitamin D3 in the skin. For a fair-skinned individual, this process occurs in as little as 15 to 30 minutes; however, wearing a shirt and shorts significantly reduces this output to approximately 1,000 to 3,000 IU because the clothing acts as a physical barrier to the UVB rays necessary for synthesis. According to research published by Dr. Michael Holick in the Journal of Investigative Medicine, the body naturally regulates this process, preventing toxicity by breaking down any excess vitamin D produced beyond these levels. You can read the full scholarly article on PubMed Central.” you don’t need to turn your skin pink haha, but it’s just cause we evolved to be outside, and it makes a big difference whether your Black, White or Asian/south Asian. As your genes are for that place, as a south asian born in Pakistan living in Canada, Im especially vulnerable because my genes and body expect heat and sun all day long (pakistan is very hot/sunny), so they require more raise to make the some amount of Vitamin D as an European. Doctor Vids Doctors Once Prescribed 300,000 IU of Vitamin D — Here’s What Happened video explaining the famous error on why it is horrendous to say 600-800 IU d3 is enough that the medical institutes still have not publicly changed. Vitamin D mistake Be careful with the comments saying they took massive doses for years, it depends on weight and gender, my sister only need daily 6,500 IU to maintain while I need 7,500 IU and I’m 151lbs light weight at 6,2. To raise your Vitmain D level initially I do recommend trying to get your hands on a big dose likely need doctor to prescribe, just a as a single boost dose then continue maintaince dose 5,000 IU and more, monitor blood levels. Now why do I reccomend 115nmol/l or 46.6ng/ml? I will explain, it’s because although, I believe the doctors that say going higher is safe, this is the most risk free level and must be the minimum. “A 2012 study found that traditional East African populations maintain an average vitamin D level of 115 nmol/L (46 ng/mL) due to consistent sun exposure, suggesting an evolutionary baseline for humans. These findings indicate a significant, natural divergence from typical levels found in modern Western populations. See the study Here.” This study basically took the average of 64 African men from tribes which spend their days outside, they quiet comically noted that these tribes men seek the shade during the very sunny hours since their is an abundance of sun. It is recommended you take magnesium, k2 and Vitamin A when you take Vitamin D3 to basically help boost the balance and help stabilize things faster. But you don’t need pills, Pumpkin seeds (papitas) are extremely rich in Magnesium, so a snack size pack of those, as long as you consume Dairy, Cheese, Yogurt, Milk, you will get enough k2, and Vitamin A rich foods are cantaloupe and sweet potatoe. Vitamin A is quiet important as when vitamin D is doing its thing, it needs Vitamin A to sort of pair with it. (you can research that, nothing complicated). Antihistamines, which reduce allergic reactions and some people take to improve POIS symptoms, Vitamin D controls the natural regulation of histamines in your body (preventing the allergic reaction before it can happen), so you don’t need to take any other drugs. (Theory of what happens for some people not everyone) Ejaculation --> Semen and natural cytokine increase --> Body's immunity has something messed up and triggers a severe reaction detecting either the semen or cytokine increase as a critical infection (Video explaining what your body does during sickness or immune system threat) --> Muscle weakness, brain fog, loss of appetite follow as the body begins to launch its full immune system attack (at nothing), muscles get drained of energy as the immune cells need energy and take it from there --> what is causing your immune system to be messed up? For me it was not enough Vitamin D (low blood levels below 115nmol/l or 46.6ng/ml) Vitamin D insufficiency is extremely common, that is why I'm notifying you of this. Note: 1. Not recommending mega dosing, I took 200,000 IU ONCE, just to boost. 2. I recommend you to figure out your maintenance dose (different for everyone) to maintain vitamin D3 levels above 115nmol/l or 46.6ng/ml by trying 4,000 IU to 10,000 IU daily and having blood tests checked. 3. You must check your blood levels for Vitamin D, that gives you a solid factual number to work with and keeps you safe, you want to find a maintenance dose that allows you to maintain minimum 115nmol/l or 46.6ng/ml. This is my opinion, experience and what helped me. submitted by /u/LaughingPlan3t to r/POIS [link] [comments]

Why is my 1000 IU vitamin D3 softgel bigger than my 2000 IU one?
I noticed something odd with two vitamin D3 softgels I have. The larger one is Healthy Care Vitamin D3 25 mcg (1000 IU), and the smaller one is Kirkland Vitamin D3 50 mcg (2000 IU). At first I thought the higher IU one should be bigger, but the opposite is true. Both are softgels, but the Healthy Care one is clearly larger. Is this normal? Does softgel size depend more on the carrier oil / fillers / capsule shell rather than the actual amount of vitamin D3? Just wanted to confirm whether this is expected or if I should be concerned. submitted by /u/chankittikun to r/Supplements [link] [comments]

Your vitamin D is probably doing nothing.
took me an embarrassingly long time to figure this out so figured i'd share. i was on 2000 IU daily for probably two years. label said 2000, my doctor said 2000, the RDA basically says 2000. tested my 25-OH D and came back at 28 ng/mL. my doctor said "that's sufficient, you're fine." and technically she was right, the official cutoff is 20 ng/mL, so 28 clears the bar. what nobody told me is that the 20 ng/mL threshold was established specifically for bone health. that's it. it was never meant to represent optimal levels for immune function, mood, testosterone, any of the other systems vitamin D is actually involved in. most of the functional medicine literature and a growing number of researchers treat 40 to 60 ng/mL as the real target for overall health outcomes. i was sitting at 28 convinced i was fine. problem two was timing. vitamin D is fat soluble. this is printed on every bottle and then completely ignored in terms of what it actually means. fat soluble means it needs dietary fat to absorb properly through the gut. one of the absorption studies found roughly 50% greater uptake when D3 was taken with a high-fat meal versus fasted. i was taking mine first thing in the morning with my other supplements, no food. so not only was my dose probably too low, i was absorbing maybe half of it anyway. problem three, K2. when D3 increases calcium absorption from the gut, K2 (specifically MK-7) is what directs that calcium toward bone instead of soft tissue. the two aren't just commonly stacked for marketing reasons, the mechanistic case for pairing them is solid. i wasn't taking K2 at all. so i switched. 5000 IU D3 with 100mcg K2 MK-7, taken with dinner which is my biggest meal. tested 90 days later and came back at 47 ng/mL. i've tested four more times since and been consistently in the 40 to 55 range. that single change, no lifestyle overhaul, nothing else different, moved my levels almost 20 points. just to confirm it wasn't placebo i actually ran a dumb experiment where i dropped back to 2000 IU for 8 weeks to see what happened. levels fell back to 34 ng/mL. went back up to 5000 IU, rebounded to 48 on the next test. so yeah, the dose was the issue the whole time. the thing i keep seeing is people say "i take vitamin D" like that's the end of the sentence. what dose, what form, when, with what, have you ever tested to confirm it's doing anything. those details are everything with a fat-soluble compound. most people's protocol is two years of swallowing a capsule that absorbs at half capacity and keeps their levels in a range that technically avoids deficiency but doesn't actually do much. test your 25-OH D if you haven't. it's cheap to add to a panel. get your levels, not a doctor's reassurance that you're probably fine. wrote a longer version of this with all my actual test results if you want the full breakdown, link's in my profile EDIT: if you're reading this later, the key points are: vitamin D3 absorption depends heavily on taking it with dietary fat, dosage is highly individual (2000 IU is often not enough for many people), and blood testing for 25-hydroxyvitamin D is the only way to confirm effectiveness. most guidelines define ≥20 ng/mL as “sufficient” for bone health, but many experts and studies suggest a broader optimal range closer to ~30–60 ng/mL depending on the outcome measured. taking vitamin D with a fat-containing meal can significantly improve absorption, and factors like body weight, timing, and co-nutrients (like vitamin K2 and magnesium) can influence results. submitted by /u/Timely_Ad8989 to r/Supplements [link] [comments]

For more details, visit PubMed.” 11 times, CAN YOU BELIEVE THAT cause I can! ”The VITAL study, a large-scale clinical trial published in The BMJ, found that adults taking 2,000 IU of Vitamin D3 daily had a 22% reductionin the rate of confirmed autoimmune diseases compared to those taking a placebo. The study, which followed over 25,000 participants for five years, suggests that Vitamin D helps regulate the immune system and may prevent the onset of conditions like rheumatoid arthritis and psoriasis, with the protective effects becoming even more significant after two years of consistent supplementation. You can view the full study summary and data on PubMed.” I just wanna mention they used 2000IU which is low and basically like nothing, which means the real percentage is way higher than 22% reduction in auto immune disorder development. now why do I call it preposterous that giving anything below 5,000 IU is way to low, well I’ll explain then link 2 doctor videos. We get Vitamim D from the sun, and hoenst that’s the best thing, if you think you can sun bath, then that will literally be better and good enough then taking any D3 oil drops, because it’s the natural way of your body. “Full-body exposure to peak midday sun until the skin begins to turn slightly pink—known as one Minimal Erythemal Dose (MED)—can trigger the production of 10,000 to 25,000 IU of Vitamin D3 in the skin. For a fair-skinned individual, this process occurs in as little as 15 to 30 minutes; however, wearing a shirt and shorts significantly reduces this output to approximately 1,000 to 3,000 IU because the clothing acts as a physical barrier to the UVB rays necessary for synthesis. According to research published by Dr. Michael Holick in the Journal of Investigative Medicine, the body naturally regulates this process, preventing toxicity by breaking down any excess vitamin D produced beyond these levels. You can read the full scholarly article on PubMed Central.” you don’t need to turn your skin pink haha, but it’s just cause we evolved to be outside, and it makes a big difference whether your Black, White or Asian/south Asian. As your genes are for that place, as a south asian born in Pakistan living in Canada, Im especially vulnerable because my genes and body expect heat and sun all day long (pakistan is very hot/sunny), so they require more raise to make the some amount of Vitamin D as an European. Doctor Vids Doctors Once Prescribed 300,000 IU of Vitamin D — Here’s What Happened video explaining the famous error on why it is horrendous to say 600-800 IU d3 is enough that the medical institutes still have not publicly changed. Vitamin D mistake Be careful with the comments saying they took massive doses for years, it depends on weight and gender, my sister only need daily 6,500 IU to maintain while I need 7,500 IU and I’m 151lbs light weight at 6,2. To raise your Vitmain D level initially I do recommend trying to get your hands on a big dose likely need doctor to prescribe, just a as a single boost dose then continue maintaince dose 5,000 IU and more, monitor blood levels. Now why do I reccomend 115nmol/l or 46.6ng/ml? I will explain, it’s because although, I believe the doctors that say going higher is safe, this is the most risk free level and must be the minimum. “A 2012 study found that traditional East African populations maintain an average vitamin D level of 115 nmol/L (46 ng/mL) due to consistent sun exposure, suggesting an evolutionary baseline for humans. These findings indicate a significant, natural divergence from typical levels found in modern Western populations. See the study Here.” This study basically took the average of 64 African men from tribes which spend their days outside, they quiet comically noted that these tribes men seek the shade during the very sunny hours since their is an abundance of sun. It is recommended you take magnesium, k2 and Vitamin A when you take Vitamin D3 to basically help boost the balance and help stabilize things faster. But you don’t need pills, Pumpkin seeds (papitas) are extremely rich in Magnesium, so a snack size pack of those, as long as you consume Dairy, Cheese, Yogurt, Milk, you will get enough k2, and Vitamin A rich foods are cantaloupe and sweet potatoe. Vitamin A is quiet important as when vitamin D is doing its thing, it needs Vitamin A to sort of pair with it. (you can research that, nothing complicated). Antihistamines, which reduce allergic reactions and some people take to improve POIS symptoms, Vitamin D controls the natural regulation of histamines in your body (preventing the allergic reaction before it can happen), so you don’t need to take any other drugs. (Theory of what happens for some people not everyone) Ejaculation --> Semen and natural cytokine increase --> Body's immunity has something messed up and triggers a severe reaction detecting either the semen or cytokine increase as a critical infection (Video explaining what your body does during sickness or immune system threat) --> Muscle weakness, brain fog, loss of appetite follow as the body begins to launch its full immune system attack (at nothing), muscles get drained of energy as the immune cells need energy and take it from there --> what is causing your immune system to be messed up? For me it was not enough Vitamin D (low blood levels below 115nmol/l or 46.6ng/ml) Vitamin D insufficiency is extremely common, that is why I'm notifying you of this. Note: 1. Not recommending mega dosing, I took 200,000 IU ONCE, just to boost. 2. I recommend you to figure out your maintenance dose (different for everyone) to maintain vitamin D3 levels above 115nmol/l or 46.6ng/ml by trying 4,000 IU to 10,000 IU daily and having blood tests checked. 3. You must check your blood levels for Vitamin D, that gives you a solid factual number to work with and keeps you safe, you want to find a maintenance dose that allows you to maintain minimum 115nmol/l or 46.6ng/ml. This is my opinion, experience and what helped me. submitted by /u/LaughingPlan3t to r/POIS [link] [comments]

Why is my 1000 IU vitamin D3 softgel bigger than my 2000 IU one?
I noticed something odd with two vitamin D3 softgels I have. The larger one is Healthy Care Vitamin D3 25 mcg (1000 IU), and the smaller one is Kirkland Vitamin D3 50 mcg (2000 IU). At first I thought the higher IU one should be bigger, but the opposite is true. Both are softgels, but the Healthy Care one is clearly larger. Is this normal? Does softgel size depend more on the carrier oil / fillers / capsule shell rather than the actual amount of vitamin D3? Just wanted to confirm whether this is expected or if I should be concerned. submitted by /u/chankittikun to r/Supplements [link] [comments]

Your vitamin D is probably doing nothing.
took me an embarrassingly long time to figure this out so figured i'd share. i was on 2000 IU daily for probably two years. label said 2000, my doctor said 2000, the RDA basically says 2000. tested my 25-OH D and came back at 28 ng/mL. my doctor said "that's sufficient, you're fine." and technically she was right, the official cutoff is 20 ng/mL, so 28 clears the bar. what nobody told me is that the 20 ng/mL threshold was established specifically for bone health. that's it. it was never meant to represent optimal levels for immune function, mood, testosterone, any of the other systems vitamin D is actually involved in. most of the functional medicine literature and a growing number of researchers treat 40 to 60 ng/mL as the real target for overall health outcomes. i was sitting at 28 convinced i was fine. problem two was timing. vitamin D is fat soluble. this is printed on every bottle and then completely ignored in terms of what it actually means. fat soluble means it needs dietary fat to absorb properly through the gut. one of the absorption studies found roughly 50% greater uptake when D3 was taken with a high-fat meal versus fasted. i was taking mine first thing in the morning with my other supplements, no food. so not only was my dose probably too low, i was absorbing maybe half of it anyway. problem three, K2. when D3 increases calcium absorption from the gut, K2 (specifically MK-7) is what directs that calcium toward bone instead of soft tissue. the two aren't just commonly stacked for marketing reasons, the mechanistic case for pairing them is solid. i wasn't taking K2 at all. so i switched. 5000 IU D3 with 100mcg K2 MK-7, taken with dinner which is my biggest meal. tested 90 days later and came back at 47 ng/mL. i've tested four more times since and been consistently in the 40 to 55 range. that single change, no lifestyle overhaul, nothing else different, moved my levels almost 20 points. just to confirm it wasn't placebo i actually ran a dumb experiment where i dropped back to 2000 IU for 8 weeks to see what happened. levels fell back to 34 ng/mL. went back up to 5000 IU, rebounded to 48 on the next test. so yeah, the dose was the issue the whole time. the thing i keep seeing is people say "i take vitamin D" like that's the end of the sentence. what dose, what form, when, with what, have you ever tested to confirm it's doing anything. those details are everything with a fat-soluble compound. most people's protocol is two years of swallowing a capsule that absorbs at half capacity and keeps their levels in a range that technically avoids deficiency but doesn't actually do much. test your 25-OH D if you haven't. it's cheap to add to a panel. get your levels, not a doctor's reassurance that you're probably fine. wrote a longer version of this with all my actual test results if you want the full breakdown, link's in my profile EDIT: if you're reading this later, the key points are: vitamin D3 absorption depends heavily on taking it with dietary fat, dosage is highly individual (2000 IU is often not enough for many people), and blood testing for 25-hydroxyvitamin D is the only way to confirm effectiveness. most guidelines define ≥20 ng/mL as “sufficient” for bone health, but many experts and studies suggest a broader optimal range closer to ~30–60 ng/mL depending on the outcome measured. taking vitamin D with a fat-containing meal can significantly improve absorption, and factors like body weight, timing, and co-nutrients (like vitamin K2 and magnesium) can influence results. submitted by /u/Timely_Ad8989 to r/Supplements [link] [comments]

Recommend an affordable, vegan, 3rd party tested (really) Vitamin D3 / K2 if it exists.
I'm looking for Vitamin D3 (or maybe D2) and, ideally, K2 included, maybe 2000 to 5000 IU of D3. The problem is there are so many brands and variations in prices, whether or not they are vegan, and whether they are a reputable company with excellent 3rd party testing that can be verified. I also am hoping to keep costs down. Something like $0.08 to $0.12 (8 to 12 cents) a pill/capsule would be fine, but some of these are as high as 57 cents a pill, which seems like way too high. So, am I looking for a unicorn if I want: vegan (from lichen) D3 (2000 to 5000 IU) + K2 inexpensive-ish (8-12 cents/pill) actually the molecules they say they are and we can prove this Thanks for any suggestions for brands/products. submitted by /u/veganFitnessReddit to r/vegan [link] [comments]

UB Protip: Vitamin D3
Have you found yourself tired this semester? Or maybe not as motivated as usual? Many UB students do, especially during the spring semester. I was one of those students until I tried thinking of why - and then I realized that UB doesn't get a lot of sunshine this time of year. Therefore, I tried taking Vitamin D3 (2000 IU / 50 mcg) and to my surprise, I actually felt better after a week or two of taking it. A lot of stores sell it (though I order Life Extension from Amazon as it doesn't contain fish oil or soy), and I think even The Elli does - so if you find yourself low on energy or with decreased motivation, maybe Vitamin D could help! Disclaimer: This is not medical advice. Talk with a licensed physician to determine whether taking Vitamin D would be beneficial to you. submitted by /u/T_nology to r/UBreddit [link] [comments]

MK-7 to vitamin D3 ratio
I'm starting a new supplement (Complement Essential) which has 50 mcg vitamin K2 MK-7, around half the amount of a prior supplement I took (Nordic Naturals D3+K2 which had 90 mcg MK-7). The science in this area may be inexact but it seems the consensus would be 50 mcg MK-7 suffices for 50 mcg (2000 IU) of vitamin D3? Especially as MK-7 is more efficient than MK-4. The new supplement has about the same amount of magnesium (200 mg) as the Nordic Naturals magnesium complex I previously took (I understand if supplementing D then all 3 are advised to be taken). submitted by /u/aryanmsh to r/nutrition [link] [comments]

Vitamin D3 keeps rising 98.8g/dl
So here is what happened. Can anyone explain? In February 2024 my D3 level was at 19.4 ng/l, February 2025 at 40, October 2025 94.4, January 2026 at 98.8. I started substituting with 2000 IU after my first test. In 2025 I increased it to 4000IU per day and kept it stable since. I read that 1000IU per day would increase the blood level by 10. Matching the change from Feb 2024 to Feb 2025. The increase from 40 to more than 90 surprised me. Changes between Feb 2025 and Oct 2025 test: I started losing weight, about 0.4kg per week from August until now. I also optimized micronutrients such as magnesium and potassium. I am also eating about 2-3 portions of black cod per month. I am also an avid cyclist so spend a lot of time outdoors from spring to fall.

My experience on 2000 IU/1000 IU
For months and months I felt awful — and landed in the ER several times. Looking back, I think most of my symptoms were related to Vitamin D deficiency. It was even starting to impact my neurological function. At my request, my PCP tested some vitamin and iron levels. I was low on iron saturation, B1 and D. My D level was 11 ng/mL. My doc ordered me to take 2000 IU D3 for one month (I did two months) then drop down to 1000 IU. These dosages seemed low compared to everything I see here, but I followed instructions. I also paired with K2. After 6 months I retested my level and it is now at 34 ng/mL! I do feel way better but it took several months. I’d still like to keep increasing, but I was happy to see a positive change. Just my story on what seemed to be a conservative approach by my doc. submitted by /u/Drummer-Alarmed to r/VitaminD [link] [comments]

Vitamin D3 is amazing
I have never really taken supplements, I work out 4 times a week, go on walks, and try to eat Whole Foods and avoid fast food. I usually feel pretty good most days health wise but I’ve always felt slight brain fog or low energy. I stumbled on to this subreddit a while ago and just kinda browsed through everything and noticed a lot of people mentioning vitamin D3, so about two weeks ago I went to my local supermarket and just bought a vitamin D3 supplement that had 2000 IU. The difference has been huge, I don’t feel brain fog anymore and I feel like I have more energy now, I don’t know how to really describe how I’m feeling but I just feel really good compared to what I was feeling before I started taking it. At first I thought it might just be the placebo effect but I also live in Washington where we only get sunshine 3 months out of the year so I think I was just deficient in vitamin D. submitted by /u/Dangerous_Blood_8544 to r/Biohackers [link] [comments]

Magnesium Glycenate, Fish Oil, Vitamin D3 inducing depression
TLDR: I think I'm ironically making my depression worse or triggering it with these supplements. I feel anhedonic and out of it. Very unmotivated, but have energy. I started taking supplements 8 years ago for my hormones and acne, and that's when these bouts of depression started. I'm a 30 F. The stack has always been Vitamin D3, K2, Nordic Naturals fish oil, AND magnesium glycenate. I used to consume beef liver capsules or some preformed vitamin A capsules, but got scared of those and quit those a while ago. I've taken beta carotene since. Of course I have found that ALL of these cause depression in some individuals on Reddit. My vitamin D levels were at 27 ng/ mL and was told to supplement this year. Trying to convince myself that vitamin D doesn't cause depression, I took 20,000 IU for 3 days and then maintained with 2000 IU with K2. Before that, I had been using magnesium glycenate and fish oil as part of my daily stack. I wasn't depressed, although I was increasingly stressed and anxious, in which I proceeded to take more magnesium glycenate. I've taken magnesium glycenate for years! Even when I'm depressed because I never heard of this, but could it be impeding my recovery. I don't know why, but when I took the vitamin D, I felt like I had hypercalcemia. Extreme anxiety and dry mouth. I was pounding down the magnesium and taking extra K2 to help. It seems illogical that my levels would even raise enough to cause toxicity that quickly, but maybe my body is sensitive. I've tried vegan D3 as well. I think doses of 800iu and under are okay, but I didn't see how that would help a deficiency. I may try D2 some day, but even when my levels get within range. I feel weird until I stop taking the supplement completely. I stopped the Vitamin D and Fish oil 3 days ago, and then after doing research, stopped the K2 and magnesium glycenate yesterday. I have a trace mineral supplemt that I added and been eating a lot of green smoothies to get extra beta carotene, natural calcium, and magnesium because I'm just so afraid of supplements now. I also just want the benefits of a whole foods. I have SLOW COMT and Moa genes. I'm heterozygous for the VDR genes. And I should be able to convert beta carotene efficiently. So, I don't really know if a preformed vitamin A supplement is necessary to help with the Vitamin D. I do this dance every year, and it's mainly after supplementing Vitamin D. I live in the North East of the USA and don't get much sun, but I'm curious as to if the magnesium glycenate could be inconsistent hurting me. It's been a staple in my life for years, but I take less when I'm not supplementing vitamin D and take way more when I am. I've been depressed in the summer and winter after supplementing. I feel more hopeful this morning, less doom and gloom, less brain fog. I feel like magnesium is so important, but I wonder if I should be talking natural calm magnesium citrate with calcium in replace of the glycenate because how can I be getting enough calcium if I'm not getting enough magnesium because of soil depletion, diet, ect? I mean, do I need to eat a box of spinach everyday? submitted by /u/TypeAtryingtoB to r/NooTopics [link] [comments]

Vitamin D3 side effects took 2 months (!) to dissipate after being in severe deficiency
I had severe vitamin D deficiency (10 ng/ml) diagnosed in December 2023. I promptly started supplementation with 5000 IU/day the same day I got the results, and later lowered to 1000-2000 IU/day for maintenance. The first 2 months were absolutely horrible. I was miserable - the main side effect was excessive daytime sleepiness. I was just so incredibly sleepy throughout the day, even with 8 hours of sleep. Even after napping, I was extremely tired. I was also very unmotivated and didn't even have energy for gaming, not just for work. It went on for so long that I didn't think it could be the Vitamin D3 for so long. But it was. Somewhere in February, I just felt back to baseline, much less tired throughout the day, and I'm still doing okay even with daily supplementation now. Magnesium had no effect whatsoever on the side effects, even though I've tried multiple forms (Citrate, Bisglycinate, Malate), nor did Vitamin K. It just took time. If anyone else has trouble with vitamin D3 side effects after being diagnosed with a deficiency, despite taking moderate doses, hang in there! Vitamin D3 apparently behaves as a neuromodulator in the brain, affecting neurotransmitters and brain health, so it makes sense to me it takes time to get used to being sufficient after a long period of deficiency. submitted by /u/Endonium to r/VitaminD [link] [comments]

Vitamin D3 + K2: My Experience & Best Brands to Buy
I've always avoided taking vitamin supplements because I didn't think I needed any. But I kept hearing about vitamin D and its numerous benefits, and since I don't get enough daily sun exposure, I thought I'd give this one a try. So I've been taking a vitamin D3 with K2 supplement for a few weeks now. Why the K2? Because these two vitamins work together in the body and vitamin K can reduce some of the harmful effects of a vitamin D overdose/toxicity. It is often advised that you should take vitamin K with D, and conveniently, many brands on the market have this combo in one supplement. What results did I experience? Well, it's hard to say for sure, but I did notice two changes that I think are a result of my supplementation with vitamins D and K: I feel a little more energetic and less lethargic. I wasn't expecting this, but I also noticed that my knee joints hurt less following certain physical activities. Regarding the second point, I've done a quick research and found out there is some scientific evidence suggesting that both vitamin D and vitamin K might be beneficial for joint pain (read more here and here). These are my recommendations for effective vitamin D supplements both men and women can take: Sports Research Sports Research is one of the best quality brands of vitamin D3 + K2 you can buy these days. It's a certified vegan vitamin D3 sourced from lichen, and it contains no junk fillers or additives. The softgels have coconut MCT oil and olive oil in them, which help with the absorption of D3 since it's a fat-soluble vitamin. Pros 2500/5000 IU per capsule Certified vegan vitamin D3 Third-party tested Contains coconut MCT oil for better absorption Clean product with no fillers Cons Expensive (like other vegan D3 supplements) Solaray Solaray has a good vitamin D3 + K2 formula with 5000 IU vitamin D3 per capsule, in addition to 50 mcg of K2 and a little bit of calcium and phosphorus. Pros 5000 IU per capsule Easy-to-swallow capsules Soy-free product Reasonable price Cons Doesn't contain oil to help with absorption NOW Foods NOW Foods is also a good brand many Reddit users trust. They make different vitamin D formulas, including D3 + K2 and D3 on its own in different strengths.
