Niferex
Generic name: iron supplement
Dosage form: tablets
What is Niferex?
Niferex contains a combination of ascorbic acid and iron (as Sumalate® ferrous asparto glycinate). Ascorbic acid is important for the skin and connective tissues, for normal chemical and hormonal production, and for the immune system. Iron (as Sumalate® ferrous asparto glycinate) is a form of the mineral iron. Iron is important for many functions in the body, especially for the transport of oxygen in the blood.
Niferex is a multivitamin/multimineral dietary supplement indicated for use in improving the nutritional status of patients with iron deficiency.
Niferex may also be used for purposes not listed in this medication guide.
