If men ate a balanced diet, we’d get all the benefits from vitamins we need to keep out bodies performing optimally. Unfortunately, men have an insufficiency in nearly all nutritional categories except meat and beans, according to the United States Department of Agriculture (USDA). The USDA “Recommended Daily Allowance”of vitamin A for men is 900 mcg. But unlike some other vitamins like vitamin C, taking too much of vitamin A can cause problems such as liver damage.
Most guys get enough vitamin A if they eat foods such as chicken, beef, pork, spinach, cantaloupes, carrots, and collard greens. But if you have been getting sick with colds regularly or your night vision isn’t what it should be, try the old sailor’s trick of taking a vitamin A booster like cod-liver oil. If you can’t stomach that, a vitamin A supplement might be what you need. Besides lowering blood cholesterol levels and protecting against the risks of heart disease and stroke, vitamin A has other distinct benefits.
Improve vision. The right levels of vitamin A can prevent night blindness by helping your eyes quickly adjust to changes from bright light and darkness. In fact, vitamin A helps ensures a healthy retina which will keep your eyes strong and even improve vision in weaker eyes. Vitamin A also keeps your eyes moist to ward off dry eye symptoms. As you get older, the right level of vitamin A can also help lower the risks of cataracts and macular degeneration commonly associated with ageing.
Boost the immune system. It is always good to have some help fighting off infections and vitamin A has been shown to have some of the same immunity-boosting antioxidant benefits as vitamin C. Vitamin A does this by increasing your body’s lymphatic system respond to threats from disease-causing antigens once germs have entered you body, while also strengthening the function of your white blood cells.
Stimulate sexual drive. Experiencing any kind of sexual dysfunction at the wrong time can be embarrassing for you and frustrating for her. A lack of the right level of testosterone in your body can lead to a decreased sex drive and a lack of your usual awesome sexual stamina. Vitamin A helps maintain your testosterone level, which not only boosts your libido but also your sperm count.
Bone, teeth, and tissues maintenance. One lesser known benefit of vitamin A is its importance in replacing worn out tissues with new, stronger ones. This important role includes keeping your bones and teeth strong. The right level of vitamin A helps keep up the formation of dentin, the hard layer just below a tooth’s surface that enhances its strength.
