How to Take It
Take it anytime
Take between meals — food blunts the rise in plasma arginine.
On an empty stomach
Split into 3 doses across the day
On the label
For adults, take one (1) tablet three times daily, preferably with meals.
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.
