Expert Verdict

Low concern. As a mineral salt of ascorbic acid (vitamin C), it is well-tolerated. May cause mild irritation at very high concentrations in sensitive individuals, similar to other ascorbic acid derivatives. Magnesium salt of L-ascorbic acid (magnesium di-L-ascorbate); provides dual benefits of vitamin C antioxidant activity and magnesium mineral delivery; more stable than pure ascorbic acid in formulation; water-soluble
