How to take it
On an empty stomach
On the label
Adults Take 1 capsule daily with meals providing protein or as directed by your healthcare practitioner.
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.
