Everyday Claims with the label against the study

Everyday Claims takes supplement, cream and food marketing and holds it against what studies measured. Collagen and NMN have human trials, though smaller and more modest than the packaging suggests. Blends sold under friendly names often have no trial of their own, and the articles take them apart one ingredient at a time, so you can see which part has evidence and which part only has a slogan.

Good first reads are collagen powder and what the evidence supports and NMN side effects reported in human trials. GHK-Cu before and after photos is a guide to judging visual claims, NAD injections vs IV compares two routes by what was measured, and peptides in sport explains where the rulebook draws its lines.
