🧪 Formulation Notes

The need for vitamin C has never been greater. Stress, environmental pollution, age and health, as well as biochemical individuality, all help to dictate our daily requirements for this essential nutrient. Unlike most other animals, humans cannot make their own vitamin C. With vitamin C being part of more than 300 bodily functions, life itself depends on daily replenishment. Is there a best form of this vital nutrient? Ester-C ascorbate, a revolutionary form of vitamin C, is the most bioavailable form developed. Metabolites in Ester-C ascorbate help the vitamin get into the bloodstream faster and in larger amounts, penetrate white blood cells more efficiently, and waste only a fraction of what other vitamin C's "send down the drain".
