The NutriQuarter Standard

What does “science-backed” actually mean?

Anyone can put those words on a product page. Here’s what they mean for our Ashwagandha KSM-66®, and where you can check the evidence yourself.

The Ingredient

KSM-66 Ashwagandha root extract

A branded, full-spectrum root extract that has been used in published human trials.

The Dose

500mg extract (12.5:1), equivalent to 6250mg root

A 60-day placebo-controlled trial in 60 stressed adults tested a standardised ashwagandha extract (240mg a day, a different branded extract from ours). It is research on ashwagandha extracts in general, not this exact product.

The Formula

Root extract, not leaf

KSM-66 is a branded, root-only extract with its own published human trials, not generic ashwagandha powder.
