What is the difference between vitamin C and vitamin C

Vitamin C and VC are different expressions for the same nutrient, with VC being the English abbreviation for vitamin C. Vitamin C is an essential micronutrient for the human body, which has antioxidant, collagen synthesis promoting, and immune enhancing effects. The chemical name of vitamin C is ascorbic acid, which contains enol hydroxyl groups in its molecular structure. It is easily soluble in water and has unstable properties. It is prone to decomposition when exposed to light, heat, or oxidants. Fresh vegetables and fruits are the main sources in daily diet, such as citrus, kiwi, broccoli, etc. Vitamin C deficiency may lead to symptoms of scurvy such as gum bleeding and slow wound healing, and long-term excessive supplementation may cause urinary system stones. In the field of pharmaceuticals and health products, vitamin C is often present in the form of chemically synthesized L-ascorbic acid, and some products may add mineral salts to enhance stability. The naturally extracted vitamin C mostly comes from coniferous cherry or citrus bioflavonoid complexes, and their absorption and utilization rates are not significantly different from synthetic vitamin C. Special dosage forms such as sustained-release tablets, effervescent tablets, etc. can reduce gastrointestinal irritation. When choosing vitamin C supplements, there is no need to deliberately distinguish between VC or vitamin C labeling. The key is to pay attention to whether the content meets the daily recommended amount. The appropriate daily intake of vitamin C for adults is 100 milligrams, and pregnant and lactating women can increase it appropriately. Daily storage should be sealed in the dark and taken as soon as possible after opening. Patients with gastric ulcers should avoid taking medication on an empty stomach, and those with a history of kidney stones should control the dosage of supplements.
