Insufficient iron intake represents one of the most common nutritional deficiencies, affecting an estimated 2 billion people worldwide, with women and children being considered the highest risk groups. Each teaspoon serving of Liquid Iron provides 15 mg of iron from microencapsulated ferric pyrophosphate, a highly bioavailable and well-tolerated form of iron. In a clinical trial on 122 premenopausal women with low iron levels, daily supplementation with 18 mg of microencapsulated ferric pyrophosphate improved iron status within 4 weeks.
