A Concentrated Root Extract With a Consistent Track Record
KSM-66 is one of the most researched ashwagandha root extracts in the world. Extracted from the root only — no leaves — via a proprietary water-based process, it is standardised to 5% withanolides and used in the majority of published clinical research on this botanical. Each two-capsule daily serving provides 1,000mg of KSM-66 — the equivalent of 12,500mg of whole ashwagandha root.

Why Standardisation Matters
Not all ashwagandha supplements list the withanolide content or specify the extraction method. Standardisation to 5% withanolides means you know exactly what you're getting in each serving — a consistent, measurable level of the key active compounds in every bottle.
The KSM-66 process uses whole roots, without chemical solvents, to produce a full-spectrum extract that retains the plant's natural composition. Organic certification and the root-only extraction process are what distinguish KSM-66 from commodity ashwagandha powder.
A Settled Daily Habit
Two capsules with food and water. That's the entirety of what this asks of you. No flavours, no measuring, no additives — just the extract, taken twice daily as part of whatever else is already part of your morning or evening. A 45-day supply per bottle means you're set for well over a month from a single order.
