Salidroside
An adaptogen-grade root extract of Rhodiola rosea, standardised to both marker groups — 3% rosavins and 1% salidroside. Rhodiola has two separate sets of actives, and a supplier who reports only one of them is not giving you the full picture, so we report both on the COA.
- Salidroside 3% / 5% / 98% (HPLC)
- Alternative grades: salidroside 3% / 5% / 98% on request
- Root only — no aerial-part substitution
- Heavy metals and microbial limits tested per lot

Questions buyers ask about this product
Which salidroside grades do you offer?
Salidroside is offered at 3%, 5% and 98%; the 98% grade is a purified standard for analytical and premium formulation use.
How do I know the material is root, not aerial parts?
We specify root only and confirm the ratio of markers that a genuine root extract produces. You can also see it in the price — material that is suspiciously cheap relative to the marker content usually is not root.
Which grade fits a sports-nutrition product?
Most endurance formulas use the 3% rosavins / 1% salidroside grade. If your label claims a higher salidroside figure, ask for the 5% / 2% grade — or one of the standalone salidroside grades (3% / 5% / 98%) — and allow a longer lead time.
Can you blend Rhodiola with other adaptogens?
Yes. We can produce a pre-blended powder to your ratio of actives, which saves you a blending step and removes the risk of your own blend drifting out of specification.
