Other Ingredients (6)

Rice FlourFiller

Rice-based ingredients carry risk of inorganic arsenic contamination (FDA and Consumer Reports). Rice accumulates arsenic from soil at higher rates than other grains. Used as a cheap filler — adds nothing beneficial.

Rice ExtractFiller

Rice-based ingredients carry risk of inorganic arsenic contamination. Vague labeling — 'rice extract' does not specify what is extracted or standardized. Used as a cheap filler with no supplemental benefit.

Silicon DioxideAnti-caking

Fine silica powder used to prevent clumping

Microcrystalline CelluloseBinder

Plant-derived cellulose used as a binder and filler in supplements

Psyllium (seed/husk)Fiber

Natural soluble fiber from Plantago ovata seed husks, widely used as a fiber supplement base

Sunflower Seed OilCarrier

Common vegetable oil from sunflower seeds used as a carrier in softgels for fat-soluble nutrients

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 for adults, take one (1) tablet daily, preferably with a meal or as directed by a healthcare practitioner.

General guidance based on the ingredients, not a substitute for the label or your doctor.
