Eight so far: creatine, Magic Mind, NAD+, fatty15, Theracurmin HP, SR-CoQ10 with PQQ, L-tyrosine, and HMB. Each page covers the form and dose the research used, what the trials found, who funded them when that matters, the cautions, and where I buy it, with plain links and no affiliate codes. The companies page profiles who makes each one.
A supplement label is a promise, not a test result. In the United States, supplements don't go through FDA review for safety or effectiveness before they're sold, so ask your doctor before you add one, especially if you take any medication.
Supplements
Creatine
The most studied supplement in sports nutrition: strength, lean mass, and maybe the brain.
Supplement
Magic Mind
A nootropic shot: what's in it, what the trials behind each ingredient tested, and what nobody has tested.
Supplement
NAD+
NR, NMN, nicotinamide, and IV NAD+: what raises NAD+, and what that does and doesn't do.
Supplements
fatty15 (C15:0)
One fatty acid with promising cohort data, two small 12-week trials, and a maker that wrote or paid for much of the science.
Supplements
Theracurmin HP
Curcumin that absorbs far better than turmeric powder, with small trials on joints and memory and a real liver warning.
Supplements
CoQ10 with PQQ
CoQ10 helped in one good heart failure trial, is a coin flip for statin aches, and PQQ is still at the small-study stage.
Supplements
L-tyrosine
An amino acid that may help thinking when you're stressed, cold, or short on sleep, and probably does little when you're not.
Supplements
HMB
A leucine metabolite sold for muscle and recovery: a small edge in untrained lifters, close to nothing in trained ones.
