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.

Fractionated oils rich in C8/C10 triglycerides used as neutral carrier or anti-sticking agent
Capsule ShellCapsule
Generic capsule shell where the label does not specify the material. Common materials are hypromellose (HPMC) for vegetarian capsules and gelatin for traditional capsules — both are GRAS-listed and safe. Fish gelatin and pullulan variants also exist.
Gum AcaciaBinder
Natural plant gum (acacia) used as a binder, stabilizer, and emulsifier in foods and supplements
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 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 caps every morning, with or without food
General guidance based on the ingredients, not a substitute for the label or your doctor.
