Calcium plays a very important role in the body. It is necessary for normal functioning of bone, nerve cells, muscle, and other vital organs and the regulatory system of the body. If there is not enough calcium in the blood, then the body will take calcium from bones, thereby weakening bones and triggering different types of bone disorders. Vitamin D3 helps the body to absorb calcium. Having the right amounts of calcium and vitamin D3 is important for building and keeping strong bones and healthy muscles. Magnesium also increases bone strength and rigidity. Vitamin A maintains good vision and healthy skin, nails, and hair. Vitamin E functions as a tissue antioxidant, thereby keeping cells healthy. Vitamin C plays a role in maintaining healthy gums, skin, and connective tissue. Folic acid plays a role in the metabolism of cell division and in the regeneration of blood and cells. Iron helps maintain healthy red blood cells, which play a role in oxygen transport. Selenium boosts the immune system. Vitamin B6 is required for the production of energy from protein, fat, and carbohydrate. Biotin helps to grow healthy skin and hair. Pantothenic acid helps maintain healthy skin and mucous membranes. Some micronutrients like copper, manganese, zinc, and chromium also play important roles in bone health. Moreover, calcium and vitamins are also necessary for the growth and development of babies, which come from a healthy mother through breastfeeding. That is why a sufficient amount of calcium, vitamins, and minerals should be taken by a lactating mother, as it is very essential for their health and development. After childbirth, a mother needs essential nutrients. Calcium, vitamin, and mineral supplements can fulfill the nutrient deficiency of the mother.
