How to take it

With food

Iron 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.

Keep it away from coffee, tea and dairy
Space it a couple of hours from Calcium, Zinc, Magnesium, Manganese and Green Tea Leaf Extract
