How to Take It
Take it anytime
Take with food — on an empty stomach it commonly causes nausea.
With food
Glutamine does better on an empty stomach, but something else in this bottle needs food. Taking the whole product with a meal is the better trade — an upset stomach is why most people stop.
Space it a couple of hours from Iron and Calcium
On the label
Take 1 capsule daily, or as directed by your healthcare professional.
General guidance based on the ingredients, not a substitute for the label or your doctor.
