Ashwagandha · The 5% Withanolide Standard: How to Read the Label
Withanolides are the bioactive compounds in ashwagandha. The 5% standardisation guarantee, not the patent name, makes a clinical-grade extract.
Most ashwagandha you can buy is sold by its patent name. The patent name is a marketing convenience, not a measure of efficacy. What your body actually responds to is the concentration of withanolides, the family of steroidal lactones that drive ashwagandha's stress-resilience and sleep effects.
Withanolides are the bioactive steroidal lactones in ashwagandha root that drive its adaptogenic effects. A clinical-grade extract is standardised to at least 5% withanolides. That means every 600 mg dose contains at least 30 mg of the active compounds, every batch, with a certificate of analysis to verify it. The 2012 stress-resilience trial published in Indian Journal of Psychological Medicine and the 2019 strength-endurance trial published in Cureus both anchor to that same 600 mg/day, 5%-withanolide standardised root extract. The guarantee, not the brand on the bottle, is what links your supplement to the studied dose.
How to read an ashwagandha label: look for “root extract” (not whole-herb), a stated standardisation percentage (5% withanolides minimum), and the milligrams of extract per serving (600 mg is the studied range). Anything missing means the brand is asking you to trust the logo instead of the chemistry.
EX1 Ashwagandha is a 600 mg root extract standardised to 5% withanolides, manufactured at WHO-GMP and AYUSH-GMP certified facilities with per-batch testing. The active dose, the standardised potency, and a certificate to prove it.
