Haem Iron
Haem Iron NZ — Real Iron That Actually Absorbs
Deep Blue Health Haem Iron is a potent source of natural haem iron, protein and amino acids — sourced from pasture-raised deer in the South Island of New Zealand. Haem iron is the form your body already recognises, absorbing at 15–35% compared with just 7.9% for ferrous sulfate.
Who it's for
Busy people, athletes, students, women with heavy menstruation, and anyone recovering from illness or low energy. A daily dose of energy and strength for optimal performance.
Why haem iron works when regular iron tablets don't
Haem iron uses a dedicated transport pathway that bypasses the things that block non-haem iron (calcium, tannins in tea/coffee, phytates in grains). That's why Haem Iron absorbs 2–4× better than ferrous sulfate and causes 38% fewer side effects like cramping, constipation and nausea.
Quality Guarantee: NZ laboratory quality tested. Made under internationally recognised HACCP Principles and Good Manufacturing Practices (GMP). No artificial flavours, colours or preservatives.

Real Iron That Actually Absorbs.
Here's what makes Haem Iron work
Haem iron is the form of iron your body already knows — the same iron that's in red meat and your own blood. It uses a dedicated transport pathway that bypasses all the things in food that block regular iron (calcium, tannins in tea and coffee, phytates in grains). That's why haem iron absorbs at 15-35% regardless of what you've eaten.
Deer Blood Powder is one of nature's richest sources of haem iron. We concentrate it via low-heat processing to preserve the iron-porphyrin structure — the thing that makes haem iron, haem iron. Combined with 20mg Ferrous Fumarate as a non-haem backup, you get coverage across both absorption pathways in every capsule.
WHAT'S INSIDE
Why Regular Iron Tablets Fail (And This One Works)
Iron deficiency is the most common nutritional deficiency in the world. Most people reach for ferrous sulfate or ferrous gluconate — the cheap synthetic iron salts in chemist-shelf iron tablets. But those forms absorb at just 7.9%, and the unabsorbed iron is what causes stomach cramps, constipation, and nausea that make so many people quit. Haem iron is a different beast entirely.
HOW IT'S MADE
From New Zealand's pasture-raised deer.
From grass-fed NZ deer farms to GMP-certified manufacturing — here's how we preserve every iron-carrying molecule.

Frequently Asked Questions
Frequently Asked Questions
Deer blood is one of nature's richest sources of haem iron — the same form of iron in human blood. Regular iron tablets (ferrous sulfate, ferrous gluconate) are synthetic iron salts that absorb at about 7.9% and commonly cause stomach upset, constipation and nausea. Haem iron from deer blood absorbs at 15-35% via a dedicated transport pathway — the same way your body processes iron from red meat — with 38% fewer side effects in clinical trials.
Most people feel a difference in energy within 2-4 weeks of daily use. Haem iron absorbs so efficiently you don't need to take high doses or wait months. For correcting a diagnosed iron deficiency, allow 8-12 weeks and retest your ferritin with your GP.
Yes — that's one of the advantages of haem iron. Unlike non-haem iron (which is blocked by calcium, tannins in tea/coffee, and phytates in grains), haem iron is absorbed via its own pathway regardless of what else is in your meal. Take with food if it helps with routine.
Iron requirements increase significantly during pregnancy and haem iron is better absorbed and gentler than synthetic iron tablets. That said, always consult your GP or midwife before starting any new supplement during pregnancy — they may recommend a specific dose or prenatal formulation.
