We promise to be honest with you. It's simple and may even sound mundane. But in an industry overrun with false labels, magic pills, and asterisks, we're here to deliver it to you straight.

We promise to be transparent

You deserve to know what’s in the vitamins and supplements you’re taking. We promise to be transparent about our sourcing practices and our supply chain. And we promise that what’s printed on our labels is what is in our product.

We promise to choose wisely

We will never claim to have the widest assortment; others can stock thousands of products. Starting with a focused selection of thirty products affords us the ability to be deliberate with respect to both efficacy and ingredient supply chain. It allows us to ensure all of our products are properly tested and verified.

We promise to give honest guidance

Honesty is the foundation of our recommendations. There are no commissioned store clerks with quotas or revolving promotions to push. We don't pretend all supplements have equal levels of scientific evidence or traditional history - because that isn't the truth. Our ethics drive our recommendations, not our bottom line.

How we evaluate products

Scientific research is nuanced and dynamic. We recognize this by classifying each product based upon a review of existing research. Our evaluation criteria includes the number of studies, consistency of results, magnitude of results, and methodology characteristics.
