Longevity and health claims, checked against the actual studies

Spermidine benefits look strong in food studies and weak in capsules: a year-long trial in 100 older adults found no memory gain from the wheat germ pills.
-
GlyNAC raised muscle glutathione 164% in one 16-week trial, yet a larger 114-person test found nothing. The difference is dose, and most products miss it.
-
Red light therapy has real trial support for skin and next-day soreness, and none for fat loss. Here is what the doses, numbers and caveats actually show.
-
The J-curve says moderate drinking protects the heart. Correct one basic bias and it collapses. What the evidence really shows about alcohol health risks.
-
Ultra-processed foods drove 508 extra calories a day in the one controlled trial. See what the science really shows about weight gain and disease risk.
-
No solid human evidence shows the epitalon peptide lengthens telomeres or extends lifespan: zero registered trials, only cell data, and a real cancer question.
-
Copper peptides (GHK-Cu) deliver modest, real skin gains in creams, but injectable GHK-Cu has zero human efficacy trials. Here’s what the evidence shows.
-
Growth hormone peptides reliably raise IGF-1, but only tesamorelin proves a real benefit. Here’s what the science shows on muscle, aging, and cancer risk.
-
The cholesterol paradox is real: those with the lowest cholesterol die soonest. But frailty, not protection, explains it, and LDL still causes heart disease.
-
Collagen peptides are the rare supplement with real human trials — but the skin benefit is modest and the joint evidence is stronger. Here’s the honest read.
