Vitamin A is important for normal vision, the immune system, reproduction, and growth and development. Vitamin A also helps your heart, lungs and skin. Vitamin A, or retinol, is one of the essential fat-soluble vitamins for the body.
Vitamin D helps regulate the amount of calcium and phosphate in the body. These nutrients are needed to keep bones, teeth and muscles healthy. A lack of vitamin D can lead to bone deformities such as rickets in children, and bone pain caused by a condition called osteomalacia in adults. Vitamin D, or calciferol, is a fat-soluble vitamin that performs many functions in the body.
Cholecalciferol (vitamin D3) is in a class of medicines called vitamin D analogs. Cholecalciferol is needed by the body for healthy bones, muscles, nerves and to support the immune system. It works by helping the body make more use of calcium from food or supplements. You all thought you knew all about vitamin D and its benefits, but you might be surprised.
Vitamin E's main role is to act as an antioxidant, trapping loose electrons - called 'free radicals' - that can damage cells. It also boosts immune function and prevents clots from forming in the heart's arteries.
Vitamin K helps make several proteins needed for blood clotting and bone formation. Prothrombin is a vitamin K-dependent protein that is directly involved in blood clotting. Osteocalcin is another protein that needs vitamin K to make healthy bone tissue. Vitamin K is the blood clotting vitamin par excellence.
Vitamin K is a fat-soluble vitamin that is important for the function of many proteins in the body, including clotting factors (II, VII, IX, X, as well as protein C and protein S), osteocalcin (a bone-building protein), and matrix Gla protein (MGP) (an anti-calcification protein), to name a few. What is vitamin K1?
