How to Take It
Take it anytime
Take it between meals, away from food.
On an empty stomach
On the label
Adults take one (1) tablet daily with food or as directed by a health care 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.
General guidance based on the ingredients, not a substitute for the label or your doctor.
