Clinically studied to stay in the immune system longer than regular Vitamin C

Metabolites are substances derived from other compounds (such as nutrients) during the process of metabolism. The metabolites in this formula help enhance the retention of Vitamin C by your white blood cells, which are a vital component of your immune system. So once you take your daily dose, it gets into your white blood cells, and stays there - for up to 24 hours, clinically studied to last longer than regular Vitamin C.

Non-acidic and gentler on your stomach than regular Vitamin C This formula is manufactured by a unique process using no chemical solvents. The process neutralizes pH, which means its non-acidic and gentle on your stomach.

This formula has been clinically studied to stay in the white blood cells for up to 24 hours, which is longer than regular Vitamin C. White blood cells are an important component of the immune system.
