Iron Bisglycinate

Chelated Iron — typical dose 20 mg

We don’t sell Iron Bisglycinate. Whether you actually need it — and at what dose — depends on your bloodwork. Get your analysis to find out.

What it does

Iron bisglycinate is iron bound to two glycine molecules — chelated for high absorption with none of the gastric irritation, constipation, or metallic taste of iron sulfate or fumarate. Essential where bloodwork shows low ferritin, iron, or haemoglobin. Iron deficiency is common in premenopausal women, vegetarians, frequent blood donors, and adults with chronic gut conditions.

Key benefits

  • Haemoglobin formation
  • Energy and oxygen delivery
  • Cognitive clarity
  • Reduced fatigue

The evidence

Multiple RCTs confirm bisglycinate is better tolerated and better absorbed than sulfate. Strong evidence for correcting verified iron deficiency anaemia. Should not be supplemented without bloodwork confirming low ferritin or iron stores.

Where to buy

If your analysis calls for Iron Bisglycinate, this is the quality, single-ingredient version we’d reach for:

ThorneIron Bisglycinate Capsules (25 mg iron / cap)

Exactly 25 mg of gentle iron bisglycinate, single-ingredient. Only take if your bloodwork confirms low iron.

We may earn a small referral fee if you buy through this link — it never changes our pick. We hold no inventory and have no house brand.

Important

Do NOT take without bloodwork confirming deficiency — excess iron is toxic and accumulates. Contraindicated in haemochromatosis. Take 2 hours apart from calcium, dairy, tea, and coffee.
