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
Label directs 2 servings — keep one for the evening
On the label
Adults: Take 2 tablets daily or as directed by your healthcare professional
General guidance based on the ingredients, not a substitute for the label or your doctor.
