Active Iron High Potency Iron Supplement, 2X Better Absorption & Non-Constipating, Helps Support Energy, Iron Pills for Women & Men, 25mg (60 Capsules)

Why iron supplements? Iron is vital for the formation of red blood cells & hemoglobin for oxygen transportation in the body - which supports energy production. Iron also contributes to normal function of the immune system.
Do you have an iron deficiency? This affects 2.1 billion men and women worldwide. An iron supplement can help relieve symptoms. Free from artificial colors, preservatives, gluten and sugar.
Why Active Iron? Active Iron’s high potency, easy to swallow, iron pills are clinically proven to have 2X better absorption of iron sulfate and 6x less gut irritation. It is a non-constipating, gentle iron supplement kind enough to take on an empty stomach.
Who should take iron supplements? Endurance exercisers & those on restricted diets e.g. vegetarians. Blood donors, women with periods, pregnant & postpartum women. These are easy-to-swallow iron tablets for inadequate iron levels in adult men & women.
How are Active Iron supplements different? Unlike immediate release iron pills that are broken down in the stomach, Active Iron targets the gut’s natural ‘iron absorber’ site and is released where the iron is better absorbed.
