calcium carbonate + vitamin A + vitamin C + vitamin E

This is a combination dietary supplement containing four active ingredients: calcium carbonate, vitamin A, vitamin C (ascorbic acid), and vitamin E. Calcium carbonate acts as a source of elemental calcium, essential for bone health and various physiological functions; it also serves as an antacid by neutralizing gastric acid[1]. Vitamin A is a fat-soluble retinoid important for vision, immune function, and cellular growth. Vitamin C is a water-soluble antioxidant that supports immune defense, collagen synthesis, and enhances iron absorption. Vitamin E is a fat-soluble antioxidant that protects cell membranes from oxidative damage. This combination aims to provide nutritional support for individuals with increased requirements or deficiencies in these nutrients.
