24 Hour Immune Support

Immune & upper respiratory health support.

Ester-C® is the unique immune health formula containing a proprietary, clinically studied Vitamin C that stays in your immune system for 24 hours†

Ester-C® Vitamin C  is clinically shown to last longer than regular vitamin C. That's because Ester-C® Vitamin C is carefully formulated to contain vitamin C metabolites, the same metabolites that are naturally produced by your body and help enhance the retention of vitamin C by your white blood cells, a vital part of your immune system. So once you take your daily dose of  Ester-C® Vitamin C, it gets into your white blood cells, and stays there - for up to 24 hours. Vitamin C also contributes to the health of your upper respiratory tract, plus, Ester-C® Vitamin C is manufactured without chemicals to neutralize pH, which means it's non-acidic and gentle on your stomach. Ester-C® is the kinda of support you can count on 24/7!

†Ester-C® Vitamin C has been clinically studied to stay in your 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.
