Vitamin A benefits

When Vitamin A was first discovered, it was called the “anti-infective agent.” Lab animals fed a diet low in animal foods, vegetables, and fruits soon got eye infections—infections that cleared up as soon as these foods were put back into their diet. The mysterious “agent” in the foods turned out to be a fat-soluble substance that was dubbed Vitamin A.
To fend off infections and illnesses, Vitamin A benefits you put up strong front-line barriers to infection. How? By helping your body’s epithelial tissues—the cells that make up your skin and line your eyes, mouth, nose, throat, lungs, digestive tract, and urinary tract—grow and repair themselves. These tissues line your body’s external and internal surfaces and keep out trespassers. Without enough Vitamin A, these cells become stiff, dry, and much more likely to let their guard down. When that happens, germs can easily pass through them and into your body.Natra-Bio Children's Multi-Vitamin 4 fl oz

How to get most benefits of Vitamin A and Carotenes

To get the most benefit from Vitamin A and Carotenes you should know how it works. Vitamin A and beta carotene are fat-soluble, which means you store them in your liver and in the fatty tissues of your body.VitaMinder Vitamin Chest: K

To avoid any chance of a toxic buildup, we suggest you stick to the Vitamin A in your daily multivitamin supplement and skip any additional A supplements.
But if you’re having one of those frantic days where eating right is way down on your priority list, taking a mixed carotenoid supplement can help make up for that skipped breakfast, fast-food lunch, and takeout dinner.

These supplements contain beta carotene, lycopene, lutein, and other carotenoids.
To get the most benefit of Vitamin A and beta carotene, be sure to also get sufficient amount for Vitamin E, zinc, and selenium. You need Vitamin E to help Vitamin A work more effectively; you also need extra Vitamin E if you take large doses (more than 15 g daily) of beta carotene supplements.

You need zinc to help transport Vitamin A around your body and you need selenium to help beta carotene work more effectively.
Vitamin A and beta carotene are blocked by alcohol, cigarettes smoking, birth control pills, Bile-sequestering cholesterol drugs, drug used to treat arthritis, psoriasis, or cancer.
Don’t overdo on the Vitamin A supplements—more than 5,000 IU (1,000 RE) a day can be harmful.

To avoid possible problems and get maximal benefit doctors suggest taking mixed carotenes instead. In this case you’ll get your A’s along with extra antioxidant protection.
