About vitamin A

Vitamin A is a fat-soluble vitamin. It is present in varying amounts in almost all vegetables and fruits.

It is a potent antioxidant that plays a vital role in keeping the skin, eyes and neurological functions healthy.

It also reduces inflammation by fighting free radicals.

Elimination of free radicals helps decrease the oxidative stress, which naturally slows down aging and gives you a fresh, youthful look.

Vitamin A also plays vital roles in gene regulation, supporting the immune system, building bones, and cell differentiation.

It also promotes reproductive functions and vision.

Some of the best sources of vitamin A include eggs, milk, liver, green leafy vegetables and fresh fruits (1, 2).

There are two main forms of vitamin A: retinol (the active vitamin A) and beta-carotene (provitamin A).

Active vitamin A is obtained from animal sources and it is called retinol.

The body can use it directly.

Beta carotene is obtained from a plant source.

After ingestion, beta carotene is converted into retinol.

The active form of vitamin A performs various functions in your body.

The recommended dietary allowance (RDA) of vitamin A for adults is 900 micrograms daily (3,000 IU) for men and 700 micrograms daily (2,300 IU) for women.

For pregnant women 19 years old and older the RDA is 770 micrograms daily (2,600 IU) and for lactating women 19 years old and older, 1300 micrograms daily (4,300 IU) (1, 2).

Deficiency of vitamin A can lead to vision problems like night blindness. Premature skin damage, respiratory infections, and poor bone health are all manifestations of vitamin A deficiency (1, 2).

Inefficient intake of vitamin A can lead to its deficiency. Common health conditions that can cause vitamin A deficiency are gluten sensitivity, leaky gut syndrome and inflammatory bowel disease.

Birth defects, low bone density, and liver problems are common side effects of excess vitamin A intake. Due to this reason, doctors recommend eating vitamin A rich diet instead of supplements in people with mild vitamin A deficiency (3).

The summary: Vitamin A is a fat-soluble vitamin essential for skin, eye and brain health. Its deficiency may lead to vision problems, skin damage, respiratory infections and other disorders. It has teratogenic effects and its excessive intake in pregnancy may lead to birth defects.
