Ferrous ascorbate is a chelated complex of ferrous iron (Fe²⁺) and ascorbic acid (vitamin C). It appears as a reddish-brown powder, soluble in water, and is used in oral iron preparations. The ascorbic acid component enhances iron absorption and stabilizes the ferrous state.

Commonly used in oral iron supplements such as tablets and syrups to treat iron deficiency anemia. Ascorbic acid improves the bioavailability of iron and prevents its oxidation.
Ferrous ascorbate combines high iron bioavailability with the antioxidant benefits of vitamin C. It is more stable than traditional iron salts in solution and exhibits fewer oxidative interactions with excipients in formulation.
