How to Take It

Take it anytime

Take between meals — it competes with arginine for the same transporter.

On an empty stomach

On the label

Adults take two capsules daily at mealtime.

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.
