Magnesium Glycinate

Carbonyl® Iron powder is metallic iron (Fe) with high (> 98%) iron content. It is not a salt.

It absorbs at 69%, compared to only 10 to 15% with most other forms of iron.

The high iron content and high absorption rate results in lower dose per capsules, achieving the same or better daily intake levels, compared to ferrous (Fe2+) salts (e.g., ferrous sulfate, ferrous fumarate, or ferrous gluconate),
while at the same time and most importantly, side effects like constipation and gastro-intestinal discomfort and pain are avoided.

In addition to the high iron content, a key physical property of Carbonyl® Iron is its fine spherical particle size and porousity with huge surface area, both resulting in higher human bioavailability than other iron forms. 12 Vegetarian Capsules 165 mg
