Ester-C is a unique vitamin C complex containing stomach-friendly vitamin C and the vitamin C metabolite L-threonate. L-Threonate enhances the absorption of vitamin C into the body and prolongs its presence in immune cells. Ester-C is designed to meet additional requirements, such as those in competitive sports, among smokers, or in environments with high pollution levels. It supports the immune system, particularly during periods of heightened stress, and promotes the health of connective tissue and skin. This non-acid, stomach-friendly vitamin C complex is also suitable for individuals with sensitive stomachs.
