This is a high-dose **Iron** supplement built specifically for correcting deficiency — you're getting 85mg per tablet, nearly double the 45mg tolerable upper limit, which puts it firmly in the therapeutic range used under medical supervision for iron-deficiency anemia. The iron comes as an amino acid chelate, a well-absorbed form that's gentler on your stomach than basic iron salts. The slow-release format helps further by spreading absorption over time to reduce GI discomfort.

The supporting cast is deliberately chosen for blood health. **Vitamin C** at 300mg significantly boosts iron absorption — that's a clinically meaningful dose on its own. **Folate** (400mcg as methylfolate) and **Vitamin B12** (500mcg as methylcobalamin) are both in bioactive forms your body uses directly, and both are essential for red blood cell production. The full B-vitamin panel rounds things out for energy metabolism.

At 85mg, this is not a maintenance iron product — it's designed for people with confirmed deficiency or anemia. If your ferritin levels are normal, this dose is well above what you'd want to take unsupervised. Check with your provider before starting, and consider retesting after a few months to see if you can step down.
