Vitamin C, also called ascorbic acid, is a water-soluble vitamin. Vitamin C participates in a variety of reactions in the body, such as participating in redox processes, and plays an important role in biological oxidation and reduction and cellular respiration. Vitamin C can resist the damage of free radicals to cells and improve human immunity. Some fruits and vegetables contain a lot of vitamin C, such as lemons, kiwis, cherries, citrus fruits, guava, green or red peppers, mustard greens, spinach, strawberries, grapes and tomatoes. However, vitamin C is extremely unstable and is easily destroyed during storage, processing and cooking. In addition, vitamin C is easily oxidized and decomposed. Vitamin C is found naturally in many fruits and vegetables, especially citrus fruits, berries, kiwi, and tomatoes. It is also available as a dietary supplement in various forms, including tablets, capsules, gummies, and powdered drink mixes. While most people can get enough Vitamin C through a healthy diet, some people may need to supplement with higher doses to meet their needs. As with any supplement or medication, it's important to talk to a healthcare provider before taking Vitamin C supplements.   Our Manufacturer TGYBIO was specialized in Supplements of vitamins. we supply vitamin C, vitamin B, vitamin D, vitamin A and Vitamin B12 Cyanocobalamin for sale, there also supply Vitamin B12 Mecobalamin , it's very hot selling now, we supply with lowest price and high quality,  you can contact us for free samples and more product details.
