What an extract ratio is
Herbal supplements are often made by extracting a concentrated form from raw plant material. An extract ratio such as '10:1' means 10 parts of raw herb were used to produce 1 part of finished extract [1]. So 100 mg of a 10:1 extract started from about 1,000 mg of raw herb.
Why a bigger ratio isn't automatically better
It's tempting to read '10:1' as 'ten times stronger,' but the ratio alone doesn't tell you how much active compound is present, because:
- The starting plant material's quality and potency vary.
- The extraction method and solvent determine which compounds are concentrated (and which are left behind).
- A high ratio can even concentrate the wrong parts if the process isn't designed for the active compounds.
In short, a ratio is a manufacturing description, not a guarantee of effect.
Standardized extracts are often more useful
A standardized extract specifies a defined percentage of a known marker compound — for example, 'standardized to 80% silymarin' for milk thistle. This is usually more informative than a bare ratio, because it ties the product to a measurable amount of the compounds studied — see standardized extracts explained. Even then, the marker compound isn't always the (only) active one, so standardization isn't perfect.
How this connects to dosing
Clinical studies typically use a specific extract at a specific dose (often a standardized one). To match the research, you need to know what was studied — a raw-herb amount, an extract ratio, or a standardized percentage. A ratio by itself rarely lets you do that, which is part of the broader underdosing problem.
Practical guidance
- Don't equate a high ratio with high quality or potency.
- Prefer products that disclose a standardized marker percentage and the equivalent raw-herb amount.
- Match the form and dose to the research for that herb where possible, and favor [third-party-tested](/learn/supplement-certification-seals-compared) products [2].
