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.
Ester-C 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
Stomach friendly!
