Standardised vs full-spectrum herbal extract: which one do you need?
By PuraVida Natural · 25 September 2026
A standardised extract is adjusted so a named marker compound reaches a fixed percentage in every batch. A full-spectrum extract keeps the plant's natural mix of compounds without targeting one. Choose standardised when you need a repeatable dose and a specification; choose full-spectrum when the whole-plant profile is the point.
Standardised extract
The extract is tested and blended so that one or more marker compounds meet a stated level, for example 95% curcuminoids or 10% withanolides. You can dose it precisely and compare batches and suppliers on the same number.
Full-spectrum extract
The extract keeps the plant's natural range of compounds in their natural proportions. The marker level is whatever the plant gave, so it varies more between batches, but the profile is closer to the whole herb.
How to decide
- You are making a tablet or capsule with a label claim per dose: standardised.
- You need to pass a specification from a brand or a regulator: standardised.
- Your positioning is a traditional whole-herb product: full-spectrum, or a plain herb powder.
What to ask for either way
The plant part and botanical name, the extraction solvent, the marker and how it is measured, and the batch certificate of analysis.
