What are the health benefits of Vitamin A? Vitamin A is an important nutrient that your body needs. It can help with maintaining a healthy vision, supporting the healthy function of your organs and immune system. And support the development of babies in their respective wombs in pregnant women.

The healthy recommendation is for women to consume 700 mcg daily of Vitamin A and for men to consume 900 mcg per day. And for children and adolescents to consume 300 to 600 mcg of Vitamin A per day.

Eyesight

Vitamin A is essential for preserving your eyesight and a long-term deficiency of this can cause night blindness. Night blindness is highly associated with having a high Vitamin A deficiency.

Reducing The Risk Of Cancer

There have been some observational studies that have shown that consuming Vitamin A regularly can reduce the risk of certain types of cancers such as Hodgkin’s Lymphoma, cervical cancer, lung cancer, bladder cancer, etc.

Supports A Healthy Immune System

Vitamin A plays a significant role in supporting a healthy immune system. It can help fight off infections by developing and strengthening a barrier inside your body among various illnesses. And by helping with the production and function of white blood cells.

Supports Bone Health

Vitamin A is important for bone health and bone development. Research studies have shown that people with low levels of Vitamin A are at a higher risk of bone fractures than people with normal levels.

Support A Healthy Reproductive System

Vitamin A is essential for maintaining a healthy reproductive system in both men and women. It also helps with supporting the normal growth of embryos right after conception. Vitamin A is integral in the growth of the baby while he or she is in the womb. It is responsible for the development of the baby’s major organs, skeleton, nervous system, heart, kidneys, lungs, eyes, etc.

It is important to know that if you take too much Vitamin A it can lead to dizziness, nausea, headaches, pain and even up to death if you overdose on it.

The Bottom Line is Vitamin A is an essential nutrient that your body needs to function properly. The health of your eyes is associated with how much Vitamin A you consume regularly. It also helps to support a healthy immune system as well as the health of your organs.
