Solgar Ester C is a patented method of supplementing pH neutral (non-acidic) vitamin C to prevent digestive irritation. As such, it is highly absorbable. Ester C can be used in the treatment of colds, flu and infections. It also stores in cells and tissues twice as long as regular Vitamin C giving the body a greater opportunity to absorb vitamin C for health and healing.
It also has the additional benefits of acerola, citrus bioflavonoids complex, rutin and rose hips in the Ester C ascorbate metabolite complex.
