Ask HN: What vitamins and legal nootropics take every day

Fasting, twice a week, used to be very strict but then dropped back to just having some tea.. fasting is very powerful, gave me my mojo back in mid 30s after burnout from top tier consulting firm and grad school, got testosterone boost, clarity of mind, physical fitness and confidence, amazing tool.. but body has to be of the right disposition.

There are two great YouTube channels I recommend following:<p>Dr Brad Stanfield:<p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;c&#x2F;DrBradStanfield&#x2F;videos?view=0&amp;sort=p&amp;flow=grid" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;c&#x2F;DrBradStanfield&#x2F;videos?view=0&amp;sort...</a><p>Dr Rhonda Patrick:<p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;c&#x2F;FoundMyFitness&#x2F;videos?view=0&amp;sort=p&amp;flow=grid" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;c&#x2F;FoundMyFitness&#x2F;videos?view=0&amp;sort=...</a><p>Note that they&#x27;re more about anti-aging and general health, but some nootropics will also be covered.<p>Dr Stanfield will usually list his current supplement regimin in each video. Currently it&#x27;s:<p>Nicotinamide Mononucleotide (NMN) 1g, Sulforaphane 8mg, Niacin 50-500mg, Trimethylglycine (TMG) 500mg, Vitamin K2 MK-7 90μg, Vitamin D3 3,000 IU, Omega-3 (DHA&#x2F;EPA) two capsules, Hyaluronic Acid 200mg, Pterostilbene 100mg, Collagen 10g, Niacin 50-500mg, Zinc 8.4mg, Metformin 1g, Melatonin 300mcg, Magnesium Taurate 125mg

None. Why waste your money? I eat a variety of fruit, vegetables, nuts, and legumes, along with regular exercise outside.

Nicotine. I&#x27;ve never smoked but I started experimenting with nicotine lozenges and they are great. It helps my concentrations and focus a lot. So far I&#x27;ve found minimal addictiveness and no negative effects but obviously that varies by person and you should be careful. I&#x27;ve never smoked and smoking seems to be kind to many of the negative effects of nicotine.

My personal trainer strongly recommended daily dose of creatine (~5m), but it has also had noticeable effects in daily energy (especially during the pandemic when mostly chair-bound).<p>Otherwise I suppliment fish oil (or algae), vitamin D (5000 IU&#x2F;125mg), standard multivitamin, choline (650 mg) since i cant stomach eggs every day.<p>I&#x27;ve also had good experience with B12 and Vinpocene but not regularly taken.

There&#x27;s a double blind study from Japan that suggests lions mane mushroom extract is an effective nootropic. Not sure how much follow up has been done on it.

Not sure if this is asking people what they take versus asking or recommendations.<p>Anyway, I&#x27;ve taken adrafanil which is legal in the US at least because I have a erratic and often brutal sleep schedule. It does for me what I always thought caffeine was supposed to do, but never did for me: provide a subtle, but noticeable wakefulness effect even under multiple days of not having slept.

Daily:<p>vitamin D3 20&#x27;000 UI + vitamin K2 MK7 200 μg<p>vitamin C 1g<p>Zinc 15 mg<p>My main goal is to keep in my blood vitamin D3 (25 OH) level more or less at 100 mg&#x2F;ml.
