Definition Of Fat Soluble Vitamins
Vitamin A helps your vision, immune, and reproductive systems. It also keeps your heart, lungs and kidneys working properly. Vitamin D, along with calcium, keeps your bones strong by preventing diseases such as rickets, a disorder that causes bones to become soft and weak in children.
Vitamin D also helps your muscles move, improves your immune function and helps reduce inflammation. Vitamin E acts as an antioxidant that protects your body from free radicals, which are molecules that damage your cells. It also boosts your immune system and keeps blood moving through your blood vessels without clotting.
Vitamin K, conversely, allows your blood to clot. It also helps your body by making proteins for healthy bones and tissues. Storage: Fat-soluble vitamins are stored in your liver and fatty tissue.
Longevity: Fat-soluble vitamins last longer in your body, because you do not need them every day. They can be tucked away until they are required for such functions as blood clotting, as in the case of vitamin K.
Absorption and Excretion: The fat-soluble vitamins are absorbed through the small intestine with dietary fat and are excreted slowly. In general, a healthy diet will not cause toxicity, but taking supplements at high levels may create an imbalance of vitamins and cause illness.
