How to Take It
Take it anytime
Absorbs substantially better fasted — take it about 30 minutes before a meal.
On an empty stomach
On the label
Adults take one tablet once or twice daily at mealtime. Do not chew tablets.
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.
