Read the reviewThe record, in brief
Strengths: genuine transparency — a single 100 mg C15:0 ingredient, vegan, GRAS, batch-tested. Cons: the premise is unconfirmed (C15:0 isn’t recognized as essential by the National Academies), the pivotal trials are small and partly company-funded and mostly null, and one watchdog (CSPI) said “save your money.”
How we score fatty15
