What Makes KSM-66 Ashwagandha Different From Standard Extract
Quick answer: KSM-66 is a specific, trademarked, standardised ashwagandha root extract - made only from the root (not leaves), processed with a particular extraction method, and standardised to a consistent percentage of withanolides, the compounds ashwagandha is studied for. Not all ashwagandha supplements use it - checking for it by name is the easiest way to know exactly what you're getting rather than a generic, unspecified "ashwagandha extract."
Root-Only vs Root-and-Leaf Extracts
Some cheaper ashwagandha extracts use a mix of root and leaf, or leaf alone - a different, and traditionally less studied, part of the plant compared to root-only extracts like KSM-66. If a product doesn't specify which part of the plant it uses, that's worth checking directly with the brand.
What "Standardised" Actually Means
Ashwagandha's withanolide content can vary a lot between raw plant sources. A standardised extract guarantees a consistent percentage of withanolides in every batch, so you know what you're getting dose to dose, rather than relying on raw plant material that varies in potency depending on growing conditions.
Is KSM-66 "Better"?
It's one of the most extensively studied ashwagandha extracts specifically, which means there's more research using this exact extraction and standardisation to point to - rather than a general assumption that "ashwagandha" as a category behaves the same regardless of extract quality. That doesn't mean other extracts don't work, just that KSM-66 has a clearer research trail behind the specific product you'd be buying.
