How Iron (Bisglycinate) Works
Iron is the central atom in hemoglobin (carries oxygen in blood) and myoglobin (carries oxygen in muscles). It's also essential for electron transport chain enzymes (energy production), DNA synthesis, and immune cell function. Iron bisglycinate is chelated to glycine, protecting it from phytate binding.
Recommended Dosage
Iron bisglycinate absorbs 2-4x better than ferrous sulfate with far less GI distress. Take with Vitamin C to enhance absorption. Avoid taking with calcium, tea, coffee, or dairy within 2 hours. Best on empty stomach, but take with food if nausea occurs.
