The Open Supplements Database

Every supplement.
Every ingredient.
One open database.

OSDb is the open, structured data layer for sports nutrition. Indexed, comparable, athlete-first. Built in public.

For athletes

Transparent, comparable data on what you actually fuel with. The ingredient label, made readable.

For brands

A level playing field. Your product, your spec, indexed alongside every other. Found by athletes who care about what is in the bottle.

For developers

Structured supplement data, ready to build on. A public, read-only API is part of the plan.

Built on OSDb today

Three apps, one database.

What is next

More categories. More coverage. More in the open.

OSDb starts with energy gels and grows from there: drinks, chews, bars, recovery products. Every category endurance and strength athletes actually use. We will keep building in public, week by week.
