Key Differences

Vitamin C, also known as ascorbic acid, is an essential vitamin required for various body functions, including collagen synthesis and the proper function of the immune system. Ester C, on the other hand, is a patented formulation of Vitamin C that includes calcium ascorbate, which is less acidic and could be gentler on the stomach.
Both Vitamin C and Ester C provide antioxidant properties, which means they can help protect the body from harmful free radicals. While the benefits of Vitamin C are well-established and widely recognized, Ester C claims to offer the added advantage of being longer-lasting in the body and being absorbed more effectively.
When it comes to dosage and intake, Vitamin C supplements are available in various forms, from chewables to capsules to powders. Ester C, given its proprietary nature, might be found in specific branded supplements.
Vitamin C is water-soluble, meaning excess amounts are excreted from the body and it needs to be regularly consumed. Ester C, while also being water-soluble, touts its extended release in the body, meaning it stays active for longer durations.
The primary concern with Vitamin C for some individuals is its acidity, which can cause stomach upset. Ester C addresses this by offering a pH-neutral (non-acidic) formulation, which may be more suitable for those with sensitive stomachs.
