How to Take It
Best taken in the evening
KSM-66 is root-only and less sedating than Sensoril. Trials have dosed it both morning and evening, so either works — take it with food.
With food
On the label
As a dietary supplement, take 2 capsules, 1-2 times daily, between meals.
The label says to take it on an empty stomach. What's in this one sits better with food, and you give up little by taking it that way.
General guidance based on the ingredients, not a substitute for the label or your doctor.

This is not medical advice. Consult a healthcare provider before making changes to your supplement routine.
The score analyzes what's on the label: ingredient doses vs. studied ranges, chemical forms, evidence levels, and known interactions. It does not verify label accuracy or test for contaminants — for that, look for third-party certifications like USP or NSF.
