How does Vitamin A help the body?

Vitamin A is an essential nutrient which is consumed in the diet through food. It is vital in helping the body fight infections and many other health benefits, these are shown below.

Benefits of Vitamin A

Eye health

Vitamin A helps to aid a person’s basic vision, a person with an ample amount of Vitamin A is able to see more easily by dim light. A person deficient in Vitamin A will likely lack sufficient rhodopsin. This is found in the retina of the eye, a person lacking in this will struggle to see when light is dim. Due to this, Vitamin A also negates the impact of age-related damage on eyesight.

Skin health 

A deficiency in Vitamin A makes a person more likely to develop skin disorders. This is largely due to Vitamin A aiding in the body’s ability to remove dead skin cells. Without being able to do this, pores become blocked and skin will become itchy and irritated. In more serious cases, a person can develop acne, impacting a person’s self-esteem and even leading to mental health disorders. Due to this, it is not uncommon for medications to treat poor skin health to be rich in Vitamin A. 

Lower risk of Cancer

Although research for this is still in its infancy, studies carried out in recent years on Vitamin A indicate due to it aiding in the development of cells in the body, regular consumption of Vitamin A on a daily basis show a person has a decreased risk of cancers such as lung and bladder cancer. 

Immune system 

Vitamin A helps the body fight against infections and disease and therefore strengthens the immune system, this due to aiding in the development of white blood cells that fight infections and diseases. A person suffering from a deficiency is more likely to develop serious illnesses and take longer to recover.

Bone health

Vitamin A is one of the main nutrients needed for the body to maintain healthy bones. Research indicates that a person with low levels of Vitamin A is much more likely to develop fractures and bone breaks. An adolescent still developing will require Vitamin A in order to grow and develop stronger bones. It is important to consider that other nutrients such as Calcium and Vitamin D are also important contributors to the overall condition of a person’s bones, therefore sufficient levels of all of these are required for overall bone health.

Vitamins A in the diet

The recommended daily intake of Vitamin A is 900mcg per day for a man and 700mcg per day for a woman. This is easily achievable through eating a balanced diet rich in foods such as dairy products, eggs and some oily fish. A person struggling to meet these daily amounts over a long period can consider taking supplements but should also seek medical guidance and advice while considering the recommendation of the supplement.
