An honest, evidence-based breakdown of AG1 (Athletic Greens). We analyze every ingredient, compare doses to effective levels, and assess whether the premium price is justified.
A comprehensive ingredient-by-ingredient analysis of AG1 (Athletic Greens). We examine every blend, estimate real doses, compare to clinical thresholds, and calculate what you are actually paying for.
Iron, folate, calcium, vitamin D -- which supplements women actually need based on clinical evidence, and which 'women's blends' are just marketing with a pink label.
Biotin deficiency is extremely rare, RCT evidence for hair benefits is nearly nonexistent, and megadoses can interfere with lab tests. Here is what actually works for hair.
