The health benefits of Vitamin A become obvious in a blemish free healthy skin, strong bones as well as a supple body that is free from infections. The fat soluble vitamin is considered to be an essential part of our body building process with the vitamin A health benefits getting enhanced greatly when it is supplemented with nutritious food sources like fresh fruits and green vegetables.

In addition to treating deficiency syndromes, vitamin A has several potential preventive and therapeutic uses. Vitamin A is important "medicine" for the immune system. It keeps skin and mucous membrane cells healthy. When membranes are healthy they stay moist and resistant to cell damage. The moistness inhibits bacteria and viruses from "putting down stakes" and starting infectious diseases.

Topical application of vitamin A helps relieve dry-eye disorder. When tear production and lubrication stop, the resulting dry eyes can be extremely uncomfortable. Many treatment avenues are often disappointing, with the exception of vitamin A eyedrops. good health for men Used clinically, these drops improve cell function and moistness returns to the eyes.

Not only does Vitamin A strengthen "entry points" into the human body, such as mucous membranes, the lining of the eyes, respiratory, urinary and intestinal tracts, it is also essential for the lymphocytes, or white blood cells, that fight infection once in the body

Vitamin A, when converted into the retinal (retinaldehyde) form, is vital for healthy eyes. It allows the eye to effectively distinguish between light and dark, thus improving night vision. Furthermore, vitamin A is believed to fight against cataracts, macular degeneration, glaucoma and other age-related ocular diseases.

Bones and Teeth 
When converted into retinoic acid, vitamin A effectively maintains healthy bones and teeth. Dentin, which also requires vitamin A, forms the hard layer of material within our teeth, thereby ensuring their strength. Vitamin A also plays an important role in replacing worn out or old tissue with newer tissue to ensure healthy bones and teeth.

Urinary Stones 
Urinary calculi, or solid particles in the urinary system, may cause pain, nausea and vomiting when stones are formed. Vitamin A produces a mineral compound within the body called calcium phosphate that prevents the formation of these solid particles.

As a powerful antioxidant, vitamin A fights against oxidative stress, or "cellular rust," within our bodies, thus protecting us from health problems such as cataracts, atherosclerosis, chronic obstructive pulmonary disease, and cancer.

The antioxidant properties of vitamin A combat free radicals that can damage the skin through oxidative stress. By maintaining proper moisture retention, the skin is not only protected from common dryness, but also keratinization (the process in which the epidermis hardens into a heavy material that makes up hair and nails), psoriasis (a skin disease marked by red, itchy or scaly patches), acne, and even wrinkling.
