Supplement Checker

One of the most researched supplements ever. Genuinely works for strength and muscle. Buy plain monohydrate.

Convenient way to hit protein targets. No magic — just food in powder form.

Mostly caffeine with expensive packaging. A black coffee does 80% of the job.

If you eat enough protein you already get all the BCAAs you need. Save your money.

Almost entirely marketing. Usually just high-dose caffeine in a flashy bottle.

Most people are deficient. Helps sleep quality, recovery, and muscle function. The glycinate form absorbs best.

Most people are deficient regardless of sun exposure. Supports immunity, mood, and hormone production.

Great for joints and tendons, limited muscle-building benefit. Worth it if joints are an issue.

Solid evidence for reducing inflammation, supporting joint health, and improving recovery. A standard protocol for serious lifters.

If you're deficient in zinc the benefit is real. For everyone else the T-boost is marginal. Sleep quality improvement is genuine.

Studies show no meaningful benefit for healthy people who eat enough protein. Overhyped and overpriced.

Most have no human clinical evidence. Ashwagandha is the only common ingredient with modest cortisol/stress benefits.
