Other ingredients
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
Silicon DioxideAnti-caking
Fine silica powder used to prevent clumping
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.
Lab testing
How to take it
On an empty stomach
Split into 3 doses across the day
On the label
2 capsules 3 times per day with meals or as directed by a health professional.
Labels usually say “with food” because it's gentler on the stomach, not because it absorbs better. Fasted absorbs more — start there, and switch to a light meal if it bothers you.
