Ester-C is a patented, non-acidic form of Vitamin C created through a unique water-based manufacturing process that produces calcium ascorbate—a pH-neutral compound that’s easy on the stomach. It also contains naturally occurring Vitamin C metabolites such as threonate, which enhance cellular uptake and retention in the body.

Unlike standard ascorbic acid, Ester-C is designed to be gentler on the digestive system while providing longer-lasting immune support. Its improved bioavailability allows it to stay in white blood cells for up to 24 hours, offering extended antioxidant protection and more efficient delivery at the cellular level.

At FitHealthy.eu, our Acid-Free / Ester-C range includes high-quality formulas backed by science and trusted by nutritionists. Whether you're looking for enhanced absorption, reduced acidity, or reliable immune support, our curated selection of Ester-C supplements delivers next-generation wellness without compromise.
