Vitamin C is an essential nutrient that your body needs to function optimally, but did you know that your body cannot produce this vitamin on its own? This means you are entirely dependent on your diet and supplements to get enough vitamin C. Vitaminstore's Vitamin C offers a reliable solution to meet your daily needs.
Vitamin C is known for its powerful support of the immune system. Additionally, vitamin C contributes to reducing fatigue and supports your energy levels. Vitamin C is a potent antioxidant that protects your cells from oxidative damage caused by external influences, such as air pollution and UV radiation. Moreover, Vitamin C plays an important role in the absorption of iron from food, which is essential for a healthy iron level in your blood. Vitamin C is also crucial in beauty care. It helps in nourishing the skin from within! It is important for the formation of collagen, which supports the firmness of the skin. This contribution to collagen formation is therefore not only important for the skin but also for the blood vessels, cartilage, bones, teeth, and gums.
What makes the Ester C 500 mg from Vitaminstore so special? Ester C is a special, patented form of vitamin C, also known as calcium-L-ascorbate. What distinguishes Ester-C® from regular vitamin C (ascorbic acid) is that it is absorbed into the blood twice as quickly and remains available in the body twice as long. This means your body benefits from the advantages of vitamin C for a longer period. Ester-C® is acid-free, which means it is gentle on the stomach and well-tolerated, even at high doses. This makes Ester-C® an excellent choice for people who are more sensitive to the acidic forms of vitamin C.
