What it is
Iron is the metal at the centre of hemoglobin — the molecule that allows red blood cells to carry oxygen.
How it works
Iron is incorporated into hemoglobin, myoglobin, and the cytochromes of the mitochondrial electron transport chain. Without it, oxygen delivery falters — and so does energy.
The protocol
Test before you supplement. If indicated, 18–25 mg of bisglycinate iron daily, with vitamin C, away from coffee, tea, and calcium.
Sourcing
Bisglycinate (chelated) form is gentler on the stomach and well absorbed. Avoid ferrous sulphate if it causes GI distress.
Honest caution
Test ferritin first — too much iron is harmful. Avoid supplementation in haemochromatosis or without confirmed deficiency.
What it supports
- Oxygen transport — Hemoglobin and myoglobin synthesis.
- Cellular energy — Iron-dependent enzymes in the mitochondria.
