Vitamin A is a fat-soluble compound that is important for human health. Vitamin A helps maintain healthy vision and ensures the normal function of the immune system and organs. It also supports the proper growth and development of the baby in the womb. Here are 6 important health benefits of vitamin A.
1. Protect your eyes against night blindness and vision loss caused by aging
Vitamin A is essential for vision protection, as it converts light entering the eye into electrical signals that are transmitted to the brain.
In fact, one of the first benefits of vitamin A deficiency can be night blindness. Because vitamins are the main components of the pigment Rhodopsin. Rhodopsin is found in the retina of the eye and is extremely sensitive to light. People with this condition can still see normally during the day. But their vision in the dark was diminished as their eyes had to work hard to adjust to the lower levels of light.
In addition to helping to prevent night blindness, getting enough beta carotene can help slow the loss of vision that some people experience as they age.
2. Vitamin A helps reduce the risk of some cancers
Cancer occurs when abnormal cells begin to grow or divide in an uncontrolled way.
In observational studies, eating more vitamin A in the form of beta-carotene has been associated with a reduced risk of certain types of cancer. These include Hodgkin’s lymphoma, and cervical, lung, and bladder cancers.
Currently, the relationship between vitamin A levels in your body and cancer risk is not fully understood. However, current evidence suggests that adequate vitamin A intake, especially from plants, is important for healthy cell division and a reduced risk of certain types of cancer.
In addition to supplementing vitamin A through daily meals, you can use vitamin A supplements. On the market today there are many famous healthcare brands. You can refer to Swanson vitamin supplements. This is a brand trusted by many users for its quality as well as affordable prices.
3. Vitamin A Supports a Healthy Immune System
Vitamin A plays an important role in maintaining the body’s natural defenses. These benefits of vitamin A manifest themselves in the mucus barriers in your eyes, lungs, intestines, and genitals that help trap bacteria and other infectious agents. It is also involved in the production and function of white blood cells. It helps capture and remove bacteria, as well as other pathogens, from the blood. This means that a deficiency in vitamin A can increase the likelihood of infection and delay the recovery of resistance to illness.

Acne is a chronic skin disease. These pimples appear when the sebaceous glands are blocked by dead skin or excess oil. While these pimples are physically harmless, they can have a cosmetic effect. It is more likely that one of the causes of acne is a lack of vitamin A. Adequate vitamin A intake will help keep skin healthy and reduce the risk of acne.
5. Vitamin A supports bone health
People with low blood levels of vitamin A have a higher risk of bone fractures than people with normal vitamin A levels.
However, if a person has too much vitamin A, there is also a higher risk of fracture. This means that for now, the link between vitamin A and bone health requires more controlled trials to be more definitive.
6. Vitamin A promotes healthy growth and fertility
Vitamin A is essential for maintaining a healthy reproductive system in both men and women, and for ensuring the normal growth and development of the embryo during pregnancy.
Studies in rats examining the benefits of vitamin A in male reproduction have shown that vitamin A deficiency suppresses the growth of sperm cells, causing infertility.
Similarly, animal studies suggest that vitamin A deficiency in females can affect reproduction by reducing egg quality and affecting eggs attached to the uterine wall.
In pregnant women, benefits of vitamin A is also involved in the growth and development of many major organs and structures of the fetus, including the skeletal system, nervous system, heart, kidneys, eyes, lungs, and pancreas. But too much vitamin A during pregnancy can also harm a developing baby and can lead to birth defects. As a result, many health authorities recommend that women avoid foods that contain excessive amounts of vitamin A. Such as pate and liver, as well as supplements containing vitamin A during pregnancy.
