How to Read a
Supplement Label.

Most supplement labels are designed to impress, not inform. This guide teaches you exactly what clinical dose means, why proprietary blends are a red flag, and how to verify third-party testing claims before you buy anything.

The supplement industry is largely unregulated.

Unlike pharmaceutical drugs, dietary supplements do not require FDA approval before they go to market. A brand can put almost anything on a supplement label and sell it legally, as long as they include a disclaimer that the FDA has not evaluated the claims. This means the burden of verification falls entirely on you, the consumer.

The good news is that reading a supplement label correctly takes about 60 seconds once you know what to look for. Below is a complete guide to the six elements that matter, and the nine red flags that tell you to put the bottle down.

Clinical vs. Generic

Why the extract matters more than the ingredient name.

Ingredient
Generic version
Clinical version
Saffron
Crocus sativus powder — no standardization, unknown lepticrosalide content
Affron® — standardized to 3.5% lepticrosalide, the active compound studied in RCTs
Ashwagandha
Ashwagandha root powder — variable withanolide content, often <1%
KSM-66® — standardized to ≥5% withanolides, the extract used in the Chandrasekhar RCT
Magnesium
Magnesium oxide — ~4% absorption, causes digestive distress
Magnesium glycinate — ~80% absorption, no digestive side effects
Black pepper
Black pepper powder — variable piperine content, minimal absorption effect
BioPerine® — standardized to 95% piperine, increases saffron absorption by up to 2000%
