Vitamin C as calcium L-ascorbate is particularly gentle on the stomach and therefore also suitable for very sensitive people. Another advantage is that vitamin C remains in the body longer due to naturally occurring metabolites - the organism can thus store vitamin C in the cells for up to 24 hours after ingestion. As a result, optimal care is achieved.
 
 Ester-C® is a unique form of Calcium Ascorbate Threonate. It is produced using a patented water-based manufacturing process. The result is a pH balanced product that contains the naturally occurring vitamin C metabolite. The main advantages of Ester-C® are its fast absorption, the 24-hour storage in the immune system and the neutral pH value, which makes the product so gentle on the stomach.
