Vitamins are very crucial in everyday life. Vitamins support life differently. They help in boosting immunity and removing toxins in the body. The therapeutic use of vitamins includes but is not limited to stress management, healthy diet management, muscle exercises, and blood sugar level management.
Vitamin A: Carotenoids and Retinoids
Vitamin A is needed for vision functioning and mucus membranes maintenance. Substantially, the vitamin is also required for essential immune-boosting by enhancing the growth of white cells production. Vitamin A occurs naturally only in foods of animal origin, such as liver, butter, whole milk, and egg yolks, but the body converts certain carotenoids, especially β-carotene, to vitamin A.
Vitamin D is famously known for bone formation and structuring. Vitamin D helps in bone formation by promoting intestinal absorption of calcium and phosphorus. The value of vitamin A in mineralizing the elements helps children avoid weak bones and leads to rickets. Vitamin D has two major forms: D2 (ergocalciferol) and D3 (cholecalciferol). D2 is commercially produced and sold in stores. The action of sunlight produces D3 on the skin pigments in the precursor 7-dehydrocholesterol. Vitamin D also occurs naturally in fatty fish, butter, liver, and egg yolk.
Vitamin E is a naturally occurring antioxidant that protects the cell membranes by preventing the oxidation of fatty acids. Vitamin E is also known to be responsible for active reproductive health. Natural sources of vitamin E include vegetable oils and fats found in nuts, seeds, whole grains, and wheat germ.
Vitamin K helps in blood clotting substantially. It supports blood clotting by helping form clotting agents and factors in the liver. Plants make the vitamin K2 homologs (menaquinones), while Bacteria make vitamin K1 (phylloquinone). Vitamin K occurs naturally in dark-green leafy vegetables.
