Vitamin A is group of fat-soluble retinoids that are essential to your immune system, growth of bone tissue and treatment of skin disorders. For men 60-years-of-age, vitamin A can help improve vision and treat age-related muscular degeneration.

It is important you get the right amount of vitamin A daily; as you get older, you are more vulnerable to vitamin deficiencies. Although vitamin A deficiency is rare-- take too much and you can become sick.


Vitamin A is involved in maintaining cell growth cellular differentiation; it also plays a role in liver, lung and kidney function. An active form of vitamin A is retinol, which is important for the vision in low light and the health of your retinal tissue in the eyes.

According to Medline Plus, vitamin A protects the heart and slows down the ageing process. Men that don’t get enough vitamin A are at higher risk of developing cancer, heart disease and visual problems.

Recommended Daily Allowance

From 14 years and older, you need 900 micrograms of vitamin A daily, according to Medline Plus. The recommend daily allowance is how much of the vitamin your body needs on a daily basis to function. You can use the RDA as a guide when taking supplements or eating nutritious food to reach your daily goal.

Tolerable Upper Intake Level

How much vitamin A you need depends on your health, age and medication, which may affect your body’s ability to absorb vitamins. The tolerable upper intake level of vitamin A for a 60-year-old is 3000 micrograms.

This is the highest amount of vitamin A that you can consume without developing adverse effects. The upper limit intake may be suitable for people that take medication that can affect your vitamin A levels. Consult a doctor before taking the upper limits of vitamin A daily.

Vitamin-A Rich Food

Vitamin A comes from two sources-- preformed retinoids and provitamin carotenoids, which are present in animal products and green, orange and yellow vegetables. The Office of Dietary Supplements suggests the best sources for vitamin A are fish oils, liver and fortified cereals. Carrots, spinach, beef liver and sweet potato are additional good food sources for vitamin A.
