Browse all supplements in our guide, organised by category. Each entry covers what the supplement does, who needs it, food sources, best forms, timing, and safety notes.
Evidence ratings
Strong — well-established by multiple high-quality studies. Moderate — good evidence but not unanimous. Limited — early-stage or mixed evidence. Emerging — frontier science, promising but not proven.
Food first
Every supplement page shows whole food sources before recommending a supplement — because food should always be the first answer.
