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

Take 1 capsule daily with a meal.

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.
