HAVE SOME A



Vitamin A, an antioxidant, helps protect brains cells from harmful free radicals and benefits the circulatory system so blood flow to the brain remains strong. 
Vitamin A is essential to memory and learning. It also promotes healthy cells and tissues.
Vitamin A comes in several forms. Retinol, known as preformed vitamin A, is found in animal foods. Another form of vitamin A is group  called carotenoids, which include beta-carotene. Beta-carotene is the carotenoid most readily converted by the body into vitamin A.
Food rich in vitamin A ( retinol) include beef liver, fish oil, and fortified foods such as milk. Foods rich in A ( beta-carotent) include sweet potatoes, carrots, kale, spinach, apricots, cantaloupe, broccoli, and winter squash. 
Most supplements break down vitamin A into beta-carotene and retinol on their labels. Too much retinol can led to headaches, dry and scaly skin, bone and joint, liver damage, vomiting, loss of appetite abnormal bone growth, nerve damage, and birth defects, Event thought beta-carotene is not toxic to the body it is better to not overdo it. Vitamin A has a UL ( upper limit) set at 3,000 micrograms (mcg) or 10,000 IU (international units) per day for adult over eighteen.
