How to Take It
Best taken in the morning
The Iron in it is what pulls this toward the morning. Take it with a meal containing fat — the vitamin A in it absorbs poorly without one.
With a meal containing fat
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 high-oxalate foods like spinach, coffee and tea
Space it a couple of hours from Zinc, Magnesium, Manganese and Green Tea Leaf Extract
On the label
