Other Ingredients (3)
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.
Magnesium StearateLubricant
A salt of stearic acid used as a lubricant in tablet and capsule production
Microcrystalline CelluloseBinder
Plant-derived cellulose used as a binder and filler in supplements
How to Take It
Best taken in the morning
Contains Rhodiola rosea, which is stimulating — keep it to the morning. Ashwagandha is easier on the stomach taken with food.
With food
Rhodiola rosea does better on an empty stomach, but something else in this bottle needs food. Taking the whole product with a meal is the better trade — an upset stomach is why most people stop.
On the label
Take 2 vege capsules daily, as a dietary supplement, or as directed by a health care professional.
General guidance based on the ingredients, not a substitute for the label or your doctor.
