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
Microcrystalline CelluloseBinder
Plant-derived cellulose used as a binder and filler in supplements
How to Take It
Take it anytime
Take between meals — food blunts the rise in plasma arginine.
On an empty stomach
On the label
Take two (2) capsules daily, preferably with food 1-2 hours prior to physical activity or as directed by a healthcare professional. For maximum effect, take consistently.
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.
General guidance based on the ingredients, not a substitute for the label or your doctor.
