Reading Supplement Labels

August 27, 2026 · 4 min read

Not every supplement label tells you everything you'd want to know. Here's what real transparency looks like.

The Supplement Facts Panel

A clear label lists every active ingredient by name, along with the exact amount per serving \u2014 not just a "proprietary blend" total.

Why Proprietary Blends Are A Yellow Flag

When a label lists ingredients without individual amounts, you can't compare the formula against published research doses, which usually specify how much of an ingredient was actually studied.

What We Look For

Named ingredients, disclosed amounts, a manufacturing facility certification, and a clear guarantee policy are the basics we'd want to see on any label before recommending a product.

Being Honest About Gaps

Sometimes a label genuinely isn't legible or available from the sources we can access \u2014 in that case, we think saying so plainly is better than guessing.
