Iron is the metal at the centre of hemoglobin — the molecule that allows red blood cells to carry oxygen.
Deficiency is the most common nutritional deficiency in the world, especially among menstruating women, plant-based eaters, and endurance athletes. Symptoms run from fatigue to brittle hair to cold extremities.
How it works in the body
Iron is incorporated into hemoglobin, myoglobin, and the cytochromes of the mitochondrial electron transport chain. Without it, oxygen delivery falters — and so does energy.
What you can expect
Oxygen transport
Hemoglobin and myoglobin synthesis.
Good for: energy
Cellular energy
Iron-dependent enzymes in the mitochondria.

04 — PROTOCOL
Test before you supplement. If indicated, 18–25 mg of bisglycinate iron daily, with vitamin C, away from coffee, tea, and calcium.
05 — SOURCING
Bisglycinate (chelated) form is gentler on the stomach and well absorbed. Avoid ferrous sulphate if it causes GI distress.
06 — CAUTION
Test ferritin first — too much iron is harmful. Avoid supplementation in haemochromatosis or without confirmed deficiency.
What the studies say
HONEST NOTE
Peer-reviewed human evidence specifically for Iron is still limited. We use it for its traditional context and mechanistic profile, but we won't cite trials that don't exist.
All citations link to PubMed, PubMed Central or the original publisher. We do not reproduce full study text. References last verified by SACRAHAUS editorial.

Honest answers
- Should I take iron daily?
- Only with confirmed deficiency or known risk factor. Test ferritin first.
- Why with vitamin C?
- Ascorbic acid converts iron to a more absorbable form and roughly triples uptake.
