Vitamin A is possibly the most needed vitamin that can be taken by a sportsman. For a human body to operate at its top power, it must be bolstered with a multiplex supply of crucial nutrients.  Becoming unsatisfactory in Vitamin A weakens metabolic pathways that breed flawless efficiency and your effectiveness weakens.  Not good!  Daily consumption of a Vitamin A supplement may help guarantee the attendance of necessary cofactors for heaps of metabolic repercussions.

Vitamin A is a fat-soluble vitamin with four major functions in the body: (1) It helps cells reproduce normally a process called differentiation (cells that have not properly differentiated are more likely to undergo pre-cancerous changes). (2) It is required for vision; vitamin A maintains healthy cells in various structures of the eye and is required for the transduction of light into nerve signals in the retina. (3) It is required for normal growth and development of the embryo and fetus, influencing genes that determine the sequential development of organs in embryonic development. (4) It may be required for normal reproductive function, with influences on the function and development of sperm, ovaries and placenta.

Liver, dairy products, and cod liver oil are good sources of vitamin A. Vitamin A is also available in supplement form.

People who limit their consumption of liver, dairy foods, and beta-carotene-containing vegetables can develop a vitamin A deficiency. Extremely low birth weight babies (2.2 pounds or less) are at high risk of being born with a deficiency, and vitamin A shots given to these infants have been reported in double-blind research to reduce the risk of lung disease. The earliest deficiency sign is poor night vision. Deficiency symptoms can also include dry skin, increased risk of infections, and metaplasia (a precancerous condition). Severe deficiencies causing blindness are extremely rare in Western societies. Less severe deficiencies are more likely to occur with a variety of conditions causing malabsorption. A high incidence of vitamin A deficiency in people infected with HIV has also been reported. People with hypothyroidism have an impaired ability to convert beta-carotene to vitamin A. For this reason, some doctors suggest taking supplemental vitamin A (perhaps 5,000–10,000 IU per day) if they are not consuming adequate amounts in their diet. Very old people with type 2 diabetes have shown a significant age-related decline in blood levels of vitamin A, irrespective of their dietary intake.

Alex Hruby, a Carbon-Paper Interleafer from Athens, states that their health has boosted notably since taking a Vitamin A supplement.

Nuts and bolts of it? If you don't take Vitamin A your body will never accomplish maximal potential.
