Ester-C is the patented immune health formula that stays in your system for 24 hours – so you have the kind of support you can count on 24/7. Ester-C is carefully formulated to contain naturally occurring metabolites. Metabolites are substance derived from other compounds (such as nutrients) during the process of metabolism. The metabolites in Ester-C 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 of Ester-C, it gets into your white blood cells, and stays there – for up to 24 hours, clinically studied to last longer than regular Vitamin C.

Formulation re: Does NOT Contain

Plus, Ester-C is manufactured without chemicals to neutralize pH, which means it’s non-acidic and gentle on your stomach.
