I tracked my brain fog for 6 months and tested everything. Here is what actually moved the needle.
Not theory. Not 10 tips for mental clarity. Previous post was removed but I made some edits to ensure it doesn't break any rules. These are the interventions that produced measurable changes in my cognition when I tested them one at a time with a 2 week baseline between each. I used Cambridge Brain Sciences daily at 7am to track working memory, reasoning, and verbal ability. Same time, same conditions, fasted. Here is what actually did something. Tier 1: The stuff that worked immediately and obviously CO2 management. Bought a $40 CO2 monitor. My bedroom was hitting 1,800ppm by 5am with the door closed. A Harvard study showed cognitive scores drop roughly 50% at 1,400ppm compared to 550ppm baseline. I cracked the window 2 inches. Never exceeded 700ppm again. Morning grogginess I had blamed on sleep quality for years was largely gone within 3 days. Cost: $40 once. Morning electrolytes before caffeine. 500ml water with 1/4 tsp salt and a squeeze of lemon within 20 minutes of waking. Before coffee. Before anything. Research shows 1 to 2% dehydration impairs working memory and you will not feel thirsty at that level. After 8 hours of sleeping you are dehydrated. Most people's first move is coffee which is a mild diuretic. You are draining an already dry system. This took 3 days to notice. Working memory scores up about 15% on testing mornings where I did this versus did not. Phone in another room during deep work. Ward et al. 2017 in JACR showed the mere presence of a smartphone on your desk reduces available cognitive capacity even face down and on silent. I tested this for 2 weeks phone on desk versus 2 weeks phone in kitchen. The difference in sustained focus was not subtle. Verbal fluency scores were consistently higher on phone-away days. Tier 2: The stuff that took 2 to 4 weeks but the effect was real Ferritin optimization. Mine was 22. Doctor said normal. It is not normal for brain function. Soppi 2018 showed cognitive symptoms at ferritin 15 to 30 that resolved above 50. I took iron bisglycinate 25mg every other day. Not daily. Research shows alternate day dosing has better fractional absorption because hepcidin peaks 24 hours after a dose and blocks absorption of the next one. At week 6 my ferritin was 58. Processing speed on cognitive testing improved noticeably around week 4. Vitamin D loading. Mine was 19 ng/mL in February. Supplemented 5,000 IU daily for 8 weeks then dropped to 3,000 IU maintenance. Retested at 52 ng/mL. The fog improvement was gradual. Not a single moment where it kicked in. More like I looked back at my scores after 6 weeks and realized the bad days had stopped. If you live above 35° latitude and have not tested your D levels you are probably deficient October through March. Magnesium glycinate 400mg before bed. Slutsky et al. published in Neuron 2010 showing magnesium enhances learning and memory. Serum magnesium is a garbage test because it only drops when you are severely depleted. Most people in western countries are sub clinically deficient. The sleep improvement was the first thing I noticed. Deeper sleep within 3 nights. The cognitive effect followed the better sleep by about a week. Do not use magnesium oxide. Bioavailability is terrible. Glycinate or threonate. Tier 3: The stuff people do not want to hear Caffeine elimination. I tapered from 400mg per day to zero over 8 weeks. Days 1 through 3 at each step down were rough. By week 10 at zero caffeine my baseline cognitive scores were higher than my best caffeinated scores. Caffeine does not add energy. It blocks adenosine receptors. Your brain compensates by building more receptors. Now you need caffeine to reach the baseline you would have had without it. I was borrowing from tomorrow every single day for 12 years. 30 minutes of cardio. Not negotiable. Not replaceable with supplements. A single session increases BDNF by 200 to 300%. One session. BDNF is the protein that drives neuroplasticity and repair. A year of regular walking increased hippocampal volume by 2% in clinical trials. That is 1 to 2 years of age related brain shrinkage reversed. Nothing in a capsule does this. Nothing. Cutting alcohol entirely. Not reducing. Cutting. A 2017 BMJ longitudinal study followed 550 people for 30 years. Even "moderate" drinkers at 14 to 21 units per week had significantly increased hippocampal atrophy. Ebrahim et al. showed alcohol destroys deep sleep architecture at any dose. I wore a sleep tracker. Zero deep sleep on drinking nights versus 80 to 90 minutes without. That was enough data. I stopped. Tier 4: The testing that found the actual root cause Full panel bloodwork. Not a CBC. Not a basic metabolic. This is what I asked for specifically: ferritin (not just hemoglobin), B12, folate, 25-OH vitamin D, RBC magnesium, TSH plus free T4 plus TPO antibodies, fasting insulin, HbA1c, CRP. Two things came back off that my DR never would have caught. The ferritin at 22 and the vitamin D at 19. Both technically in range. Both functionally impairing my brain. What did not work: Lion's mane. Took it for 8 weeks. No measurable change on cognitive testing. Maybe it works for some people. Did nothing for me. Alpha GPC. Same. 8 weeks. Nothing on testing. Noopept. Slight subjective feeling of clarity. Nothing on objective testing. Stopped. Modafinil. Worked acutely. Tolerance built within 2 weeks. Sleep quality tanked. Net negative after a month. What people do not want to accept: The boring stuff works. The exciting stuff mostly does not. Fixing your air, water, iron, vitamin D, magnesium, sleep, movement, and removing alcohol and excess caffeine will do more for your cognition than every nootropic stack on this sub combined. I know because I tested both. One at a time. With a cognitive testing baseline. The supplements are a rounding error on top of the fundamentals. Fix the fundamentals first or you are optimizing a system that is broken at the foundation. Studies referenced: Allen JG et al. CO2 and cognitive function scores. Environ Health Perspect. 2016.

r/VyvanseADHD
Vyvanse, Creatine, L Tyrosine, Magnesium L Threonate when do you take?
I am trying to get the most out of my Vyvanse before crashing. As well as mitigating some of the crashing side effects (hitting the wall, exhaustion,POTS symptoms, including shortness of breath, and major IRRITABILITY). When the Vyvanse works, I usually get a good 3+ hours out of it and they are the most productive of my day. Would love to find a way to extend efficacy and reduce side effects. I have read that the supplements above can be helpful in conjunction with Vyvanse. Can anyone advise best times to take supplements and if there are any other others you would include or omit? Thank you!! submitted by /u/Personal-Winter-8111 to r/VyvanseADHD [link] [comments]

RE:Magnesium making RLS worse
Try just magnesium glycinate alone or try Magnesium taurate alone or Magnesium L‑threonate. Avoid malate and citrate. If your ferritin is low you are more likely to be sensitive to magnesium. Have you been tested as I suggested? If so what was it?

I tracked my brain fog for 6 months and tested everything. Here is what actually moved the needle.
Not theory. Not 10 tips for mental clarity. Previous post was removed but I made some edits to ensure it doesn't break any rules. These are the interventions that produced measurable changes in my cognition when I tested them one at a time with a 2 week baseline between each. I used Cambridge Brain Sciences daily at 7am to track working memory, reasoning, and verbal ability. Same time, same conditions, fasted. Here is what actually did something. Tier 1: The stuff that worked immediately and obviously CO2 management. Bought a $40 CO2 monitor. My bedroom was hitting 1,800ppm by 5am with the door closed. A Harvard study showed cognitive scores drop roughly 50% at 1,400ppm compared to 550ppm baseline. I cracked the window 2 inches. Never exceeded 700ppm again. Morning grogginess I had blamed on sleep quality for years was largely gone within 3 days. Cost: $40 once. Morning electrolytes before caffeine. 500ml water with 1/4 tsp salt and a squeeze of lemon within 20 minutes of waking. Before coffee. Before anything. Research shows 1 to 2% dehydration impairs working memory and you will not feel thirsty at that level. After 8 hours of sleeping you are dehydrated. Most people's first move is coffee which is a mild diuretic. You are draining an already dry system. This took 3 days to notice. Working memory scores up about 15% on testing mornings where I did this versus did not. Phone in another room during deep work. Ward et al. 2017 in JACR showed the mere presence of a smartphone on your desk reduces available cognitive capacity even face down and on silent. I tested this for 2 weeks phone on desk versus 2 weeks phone in kitchen. The difference in sustained focus was not subtle. Verbal fluency scores were consistently higher on phone-away days. Tier 2: The stuff that took 2 to 4 weeks but the effect was real Ferritin optimization. Mine was 22. Doctor said normal. It is not normal for brain function. Soppi 2018 showed cognitive symptoms at ferritin 15 to 30 that resolved above 50. I took iron bisglycinate 25mg every other day. Not daily. Research shows alternate day dosing has better fractional absorption because hepcidin peaks 24 hours after a dose and blocks absorption of the next one. At week 6 my ferritin was 58. Processing speed on cognitive testing improved noticeably around week 4. Vitamin D loading. Mine was 19 ng/mL in February. Supplemented 5,000 IU daily for 8 weeks then dropped to 3,000 IU maintenance. Retested at 52 ng/mL. The fog improvement was gradual. Not a single moment where it kicked in. More like I looked back at my scores after 6 weeks and realized the bad days had stopped. If you live above 35° latitude and have not tested your D levels you are probably deficient October through March. Magnesium glycinate 400mg before bed. Slutsky et al. published in Neuron 2010 showing magnesium enhances learning and memory. Serum magnesium is a garbage test because it only drops when you are severely depleted. Most people in western countries are sub clinically deficient. The sleep improvement was the first thing I noticed. Deeper sleep within 3 nights. The cognitive effect followed the better sleep by about a week. Do not use magnesium oxide. Bioavailability is terrible. Glycinate or threonate. Tier 3: The stuff people do not want to hear Caffeine elimination. I tapered from 400mg per day to zero over 8 weeks. Days 1 through 3 at each step down were rough. By week 10 at zero caffeine my baseline cognitive scores were higher than my best caffeinated scores. Caffeine does not add energy. It blocks adenosine receptors. Your brain compensates by building more receptors. Now you need caffeine to reach the baseline you would have had without it. I was borrowing from tomorrow every single day for 12 years. 30 minutes of cardio. Not negotiable. Not replaceable with supplements. A single session increases BDNF by 200 to 300%. One session. BDNF is the protein that drives neuroplasticity and repair. A year of regular walking increased hippocampal volume by 2% in clinical trials. That is 1 to 2 years of age related brain shrinkage reversed. Nothing in a capsule does this. Nothing. Cutting alcohol entirely. Not reducing. Cutting. A 2017 BMJ longitudinal study followed 550 people for 30 years. Even "moderate" drinkers at 14 to 21 units per week had significantly increased hippocampal atrophy. Ebrahim et al. showed alcohol destroys deep sleep architecture at any dose. I wore a sleep tracker. Zero deep sleep on drinking nights versus 80 to 90 minutes without. That was enough data. I stopped. Tier 4: The testing that found the actual root cause Full panel bloodwork. Not a CBC. Not a basic metabolic. This is what I asked for specifically: ferritin (not just hemoglobin), B12, folate, 25-OH vitamin D, RBC magnesium, TSH plus free T4 plus TPO antibodies, fasting insulin, HbA1c, CRP. Two things came back off that my DR never would have caught. The ferritin at 22 and the vitamin D at 19. Both technically in range. Both functionally impairing my brain. What did not work: Lion's mane. Took it for 8 weeks. No measurable change on cognitive testing. Maybe it works for some people. Did nothing for me. Alpha GPC. Same. 8 weeks. Nothing on testing. Noopept. Slight subjective feeling of clarity. Nothing on objective testing. Stopped. Modafinil. Worked acutely. Tolerance built within 2 weeks. Sleep quality tanked. Net negative after a month. What people do not want to accept: The boring stuff works. The exciting stuff mostly does not. Fixing your air, water, iron, vitamin D, magnesium, sleep, movement, and removing alcohol and excess caffeine will do more for your cognition than every nootropic stack on this sub combined. I know because I tested both. One at a time. With a cognitive testing baseline. The supplements are a rounding error on top of the fundamentals.

The takeaway nobody wants to accept: The boring stuff works. The exciting stuff mostly does not. Fixing your air, water, iron, vitamin D, magnesium, sleep, movement, and removing alcohol and excess caffeine will do more for your cognition than every nootropic stack on this sub combined. I know because I tested both. One at a time. With a cognitive testing baseline. The supplements are a rounding error on top of the fundamentals. Fix the fundamentals first or you are optimizing a system that is broken at the foundation. Studies referenced: Allen JG et al. CO2 and cognitive function scores. Environ Health Perspect. 2016.

Vyvanse, Creatine, L Tyrosine, Magnesium L Threonate when do you take?
I am trying to get the most out of my Vyvanse before crashing. As well as mitigating some of the crashing side effects (hitting the wall, exhaustion,POTS symptoms, including shortness of breath, and major IRRITABILITY). When the Vyvanse works, I usually get a good 3+ hours out of it and they are the most productive of my day. Would love to find a way to extend efficacy and reduce side effects. I have read that the supplements above can be helpful in conjunction with Vyvanse. Can anyone advise best times to take supplements and if there are any other others you would include or omit? Thank you!! submitted by /u/Personal-Winter-8111 to r/VyvanseADHD [link] [comments]

Magnesium L threonate weird effects
I’ve tried pretty much every form of magnesium. So I know that it’s not that I have a major intolerance to magnesium. I tried magnesium L threonate for the first time yesterday. I was kinda tired, flat, felt normal temperature at the time of taking it. After 30-40 mins I became extremely hot, hot head, crazy migraine, really dizzy, irrationally angry, and then had horrific insomnia ( I had been falling asleep fine before this). Anyone else have a weird reaction to l threonatelike his? submitted by /u/sassyfoods123 to r/Supplements [link] [comments]

is magnesium l-threonate worth it or just overhyped cash milking product?
L threonate is kind of interesting for me since i am a sufferer of depression and anxiety. i have tried glycinate and really helpful for sleep, while for anxiety i don't really know. i saw these videos recommending l threonate because unlike other magnesium, it crosses the blood-brain barrier which makes me think "what if my brain is deficient?" wanted to buy however, the price is expensive. what are your experiences with regards to these? also what brands you might recommend? thanks a bunch guys submitted by /u/CrazyAd9384 to r/Supplements [link] [comments]

To whomever recommended Magnesium L Threonate, Thank you!
Someone recommended this last week and the poor OP was downvoted to smithereens because we thought they were a paid advertisers (who knows) but I immediately ordered because I am a "try anything once that might help to alleviate my annoying fibro symptoms" type of person. Well I know it might be placebo and I also know the cognitive benefits do not start until a few weeks but I took three caps last night and had a very restful deep sleep and felt energized when I woke up. My husband is saying its placebo and "mind over matter" (which kinda pissed me off tbh) but honestly I will take whatever effects I can get at this point. I will continue taking it daily and report back in a few months. Has anyone else tried it? I took the "Magtein" to be clear.

No like literally, in my sleep, most embarrassing thing that’s ever happened to me - oh shit. Please please please let this have ever happened to someone else.

magnesium L-threonate - when I ran out
So this was wild. For a few months I was supplementing with magnesium L-threonate (Neuro-Mag by Life Extension) and I noticed my cognition was just… better. Memory sharper, focus easier, less of that “mental static” I usually fight with. Honestly it felt like I had found a missing puzzle piece. Then I ran out. And within a week or so, I started sliding hard: • Brain fog came roaring back • I felt sluggish and distracted • Mood dipped into that “flat and anxious” zone • I couldn’t get the same work done no matter how much coffee I drank It freaked me out because nothing else in my routine had changed same sleep, same diet, same stack otherwise. The only missing variable was the magnesium threonate. When my new bottle finally arrived and I got back on it? Within days the lights were back on. I could think clearly again, memory recall improved, and that weird cognitive drag lifted. submitted by /u/hockey_psychedelic to r/Supplements [link] [comments]

Magnesium L-Threonate (Magtein), curious of your thoughts?
I’m a first time user of Magnesium L-Threonate (Magtein), Life Extension brand. I got it to help me focus more during work (research analyst staring at computer all day).

Magnesium Glycinate vs. Threonate for Sleep - why I’m not using the Huberman protocol
After my last post about natural sleep stacks, a few people pointed out that this isn’t new info - and said, “Just follow the Huberman protocol.” Fair, he’s legit :) But I’ve been researching this for a few months and I’m intentionally going with Magnesium Glycinate instead of Threonate - here’s why: Threonate is excellent for long-term brain health, learning, and memory. But it’s not really focused on relaxation or muscle recovery. Glycinate, on the other hand calms the nervous system, helps lower body tension and cortisol, and has more direct clinical evidence for improving sleep quality and latency. Also it’s more affordable, better tolerated by most people, and synergizes well with L-glycine and theanine. Not saying one is “better” than the other - depends on what you want. If you’re after deeper sleep and full-body recovery, glycinate just makes more sense to me. submitted by /u/PsychologyHour to r/Biohackers [link] [comments]

Magnesium L theoronate makes me feel normal and now I know why (slow comt)
I took a reasonable amount of magnesium L-threonate for a while, and every time I took it, I noticed something—I just felt normal. Normally, I deal with a lot of rumination, high anxiety, and stress. But after taking magnesium L-threonate, that all just quieted down in a way I haven’t experienced before. Today, I was listening to a podcast featuring Gary Brecka, and he mentioned that people with methylation issues often respond really well to magnesium L-theoronate. It crosses the blood-brain barrier and helps break down catecholamines. He also brought up how people with slow comt can have trouble breaking down neurotransmitters like dopamine and norepinephrine—which really resonated with me. Has anyone else experienced this? I need to order more now I know why. submitted by /u/smbodytochedmyspaget to r/MTHFR [link] [comments]

Is there any *credible* evidence that the Threonate form of magnesium is better than any other?
Attia and Huberman often push the L-Threonate form (magtein) over non-patented forms like Magnesium Glycinate. I can't seem to find any credible evidence to support this particular recommendation, other than a sketchy paper from the individuals who also own the patent. Has Attia commented on why he thinks this form is better / safer, given there's such limited information about it? submitted by /u/pagaya5863 to r/PeterAttia [link] [comments]

Stopped taking L Threonate nightly and this is what happened
The first time I took Magnesium L Threonate, I felt so recovered the next day I was hooked. Less anxiety, less thinky-thoughts. I thought I wouldn't ever let go of it, thinking I needed it to sleep well. Almost two years later, I questioned whether my lack of creativity could receive some new context. I didn't take L Threonate a few nights... slept fine, didn't take it a few nights more. The days after I experienced my dopamine becoming more robust, and I had a flurry of creativity and drive. I went from borderline anhedonia to an experience of intrigue. Not to say the supplement was the total cause, maybe just the right change for me at the right time. I haven't taken it more than twice per month as a "reset" lately now, expecting that on those days I'll just "not be as interested in life," but just allowing myself to take a backseat to engagement. What a change of outlook I've had on the supplement these years later! Loving the drive I have back though! Anyone else experience this? submitted by /u/cosmicqtip to r/HubermanLab [link] [comments]

Magnesium L-Threonate is amazing
I suffer from pretty bad anxiety and brain fog that completely debilitates me at times. I picked up some Magnesium L-Threonate and already on the first day I felt amazing, it’s now day three and I still feel amazing. My head is clear and I feel calm. Placebo or not I’m totally cool with whatever is happening to me right now and am gonna keep taking this stuff. submitted by /u/Cuteboy52 to r/Supplements [link] [comments]

Mag L-Threonate blocks DHT, but nobody seems to care.
