Are you paying the wellness tax?

Try:

"Many supplement brands use identical active ingredients at dramatically different prices. Compare value, not marketing."

First category liveAvailable now

Start with magnesium.

We're launching with magnesium because it's one of the most popular and confusing supplement categories. Prices vary dramatically, ingredient forms differ, and many shoppers struggle to compare products fairly.

Magnesium is the first category available on Fair Shelf. More categories arrive throughout the year.

Is the cheaper option actually the same?

Expensive doesn't always mean better. Fair Shelf surfaces alternatives that appear comparable on the things that affect value — not the things that affect marketing.
