Why Standardized Botanical Extracts Outperform Plain Plant Names

Three ways a label can describe a herb

Raw powder: dried, ground plant. Cheap, variable, and often low in actives. Extract with a ratio: "10:1" means ten kilograms of plant made one kilogram of extract. It says how concentrated the material is, but not whether the solvent captured the right compounds. Standardized extract: tested and adjusted to contain a stated percentage of a marker compound, for example green tea extract with 50% EGCG or gymnema with 25% gymnemic acids. Only the third lets you compare a product with a study.

Why studies depend on it

The gymnema trial most often cited for blood sugar used a specific water-soluble leaf extract at 400 mg a day.^[1] The green tea meta-analysis found the clearest effects in trials that reported catechin content.^[2] Ginseng research tracks ginsenoside profiles, which differ between root and aerial parts.^[3] When a product does not state the marker or the amount, there is no bridge from those studies to the bottle.

Reading Payarmin's label

Payarmin lists maca root, grape seed, guarana seed, African mango seed, eleuthero root, astragalus root, green tea leaf, gymnema leaf, coleus root, capsicum fruit, grapefruit fruit and Panax ginseng aerial extract inside a 200 mg blend. None carries a ratio or a marker percentage, and none an individual amount. That is common in blends and legal. It means the label cannot tell you whether a meaningful amount of any active compound is present.

Questions to ask any maker

• What marker compound is each extract standardized to, and at what percentage?
• What is the amount of each extract per serving?
• Is identity tested on each lot, and by what method?

Our quality standards page explains how to request a certificate of analysis that would answer the third question.

Bottom line

A plant name on a label is a starting point. Standardization plus an amount is what lets you judge whether research applies.
