Iron (Ferrous Bisglycinate)

Key points

• Iron is essential for haemoglobin synthesis — low iron means less oxygen delivered to muscles and brain
• Ferrous bisglycinate is the gentlest, best-absorbed form — no constipation or nausea unlike ferrous sulphate
• Deficiency causes fatigue, brain fog, poor exercise tolerance, and hair loss — often before anaemia appears
• Vitamin C doubles iron absorption — take together; avoid calcium and coffee within 2 hours
• Do not supplement without testing first — excess iron is oxidative and stored in tissues; blood test is essential
