Overview

NOW Foods Iron 36mg uses Ferrochel iron bisglycinate chelate — a patented form of iron that is significantly better absorbed and much gentler on the stomach than standard iron supplements (ferrous sulfate). Traditional iron supplements are notorious for causing constipation, nausea, and stomach pain, which leads many people to stop taking them. Ferrochel's chelated form is absorbed through a different pathway (amino acid transport) than standard iron, resulting in fewer GI side effects and better bioavailability. At 36mg per capsule, it provides a therapeutic dose for iron deficiency.

What Could Be Better

Our Verdict

8.7/10 — Very Good

NOW Iron Ferrochel is the iron supplement that actually gets taken consistently — because it doesn't cause the constipation and nausea that make people quit. The chelated bisglycinate form is a genuine advancement in iron supplementation. Only take if blood tests confirm deficiency.
