How to Take It
Best taken in the morning
Ferrochel is iron bisglycinate — the gentle form. Most people tolerate it on an empty stomach, which is where it absorbs best. Vitamin C may help absorption.
On an empty stomach
Keep it away from coffee, tea and dairy
Space it a couple of hours from Calcium, Zinc, Magnesium, Manganese and Green Tea Leaf Extract
On the label
As a dietary supplement, take one tablet daily preferably with meals.
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.
