Benefits of Vitamin A

Some health benefits of Vitamin A are widely known. Others benefits are quite unexpected.

Every day our cells are fighting free radicals that can cause oxidative damage to DNA, proteins, and other molecules. Vitamin A is one of the most powerful ways to fight these free radicals because it’s an antioxidant. When you’re deficient in vitamin A, your immune system may weaken and you may get sick more often. This article will discuss the top health benefits of this important nutrient.

What is vitamin A? Vitamin A is a fat-soluble vitamin that has been shown to prevent many diseases, such as measles and even cancer. It’s one of 8 essential vitamins our bodies need on a daily basis. The most common sources of vitamin A are from animal products, such as liver, fish, and dairy products like whole milk.

However, there are plenty of plants that can provide you with this nutrient. For example, carrots, squash, spinach and sweet potatoes are all good sources of vitamin A. Other foods such as cantaloupe, mangoes, apricots and leafy green vegetables like collard greens provide vitamin A to your body.

Why is vitamin A so important? As we get older our bodies work slower and we may be more susceptible to illness. Vitamin A works as an antioxidant in the body that prevents damage from free radicals. It also helps build bones and it promotes healthy skin.

Well, I have already started in on the benefits of vitamin A for health, so let’s dig right in.

1. Vitamin A boosts the immune system.

A big benefit of Vitamin A is that it is vital to the proper functioning of your immune system. It supports the production of infection-fighting white blood cells and antibodies, which play a critical role in fighting pathogens in your body.

Vitamin A also supports the health of mucous membranes, which line your respiratory system and gastrointestinal tract as well as your urinary tract.

In addition, vitamin A helps control tissues that protect these membranes from pathogens. All of these roles make vitamin A incredibly important to your immune function.

2. Vitamin A reduces risk of eye diseases and supports eye health.

Vitamin A has been shown to have benefits for eye health in a number of ways. For example, it helps to enhance night vision because you need vitamin A in your eyesight twice as much at night (compared to day).

This vitamin also works with the immune system to fight infections and prevent further damage that could lead to blindness. Vitamin A also helps to keep the lens of your eye from fogging up and promotes a healthy surface of the eye that may otherwise become damaged.

And vitamin A is important for your eyesight because it helps the retina (the back part of the eye) regenerate. Vitamin A also helps you see in dim light and reduces the need for glasses or other corrective devices later in life.

3. Benefit of Vitamin A for pregnancy: helps prevent pre-term births.

Vitamin A is an important nutrient for a development fetus in the first trimester of pregnancy. This is because this vitamin helps promote normal development of lungs and protects against infections in the fetus’s respiratory system.

It appears that Vitamin A also helps increase weight gain in pregnant women at higher risk for delivering their baby too early. Therefore, getting enough vitamin A during this time period may lower your risk for delivering your baby too early.

The U.S. Institute of Medicine has determined that pregnant women need about 2,400 international units (IU) of vitamin A each day because they may not be able to store enough in their bodies during pregnancy.

3. Vitamin A relieves fever symptoms.

Fevers are a common symptom of many illness, and vitamin A’s role in fighting these fevers is well known. Vitamin A appears to help suppress certain types of fevers, such as fevers caused by influenza and measles.

This is because vitamin A helps protect cells in your body from damage by free radicals. Vitamin A also supports the activity of your body’s natural fever-fighting mechanism (called the hypothalamus-pituitary-adrenal axis).

4. Big benefit of Vitamin A: Combat cancer cells.

Studies have been shown that vitamin A may help to prevent cancer because it can stop tumor cells from multiplying. It does this by suppressing the growth of cancer cells due to the antioxidant properties of vitamin A. Vitamin A has also been shown to activate T cells and help them target cancer cells in the body.

Researchers noted that women who took vitamin A supplements at least once a week had a one-third lower risk of developing cancer of the uterus.Vitamin A may also help prevent or slow the spread of prostate cancer because it can prevent cell division in prostate cancer cells and promote cell death. Prostate cancer is one of the most common cancers in men, so this is a big benefit.

In addition, vitamin A has been shown to slow the growth of pancreatic cancer cells and lymphoma cells. It may also have a slight benefit in preventing lung cancer. However, more research is needed to conclusively determine its benefits in fighting this type of cancer.

5. Vitamin A supports bone health.

Vitamin A is an important nutrient for bone health because it helps your body absorb calcium. One study examined people with osteoporosis and found that taking vitamin A supplements caused their bone mineral density to increase significantly, which made them less likely to develop further fractures.

Also, Vitamin A is important for good bone growth and development so it may reduce your risk of osteoporosis later in life. It’s important, however, to get enough vitamin A as a child and teenager (when most bone growth occurs) because you cannot make new bone once you’ve stopped growing.

It supports bone health by helping your body absorb calcium when your food contains it. Vitamin A can also help to maintain healthy blood levels of this essential mineral.

6. Vitamin A is an antioxidant.

Vitamin A can help protect cells from the damage caused by free radicals in your body. Vitamin A is also called the “antioxidant vitamin” because it helps to keep your cells from becoming oxidized and damaged. Over time, oxidation may play a role in the development of certain cancers and other health issues (such as arthritis or macular degeneration).

7. Prevent inflammation with Vitamin A.

Studies have also shown that vitamin A may be able to help reduce inflammation. It does this by helping your body stop the production of inflammatory proteins called cytokines.

Vitamin A is thought to help with this process because it helps to keep cells healthy and operating smoothly. When your cells are healthy, they can better communicate with each other and protect you from inflammation in the body. Vitamin A also plays a role in preventing oxidation, which may play a major role in the development of certain cancers.

8. Vitamin A protects against cataracts.

Vitamin A can help prevent cataracts by keeping the lens of your eye healthy and flexible. If you don’t get enough vitamin A in your diet, it can cause the watery part of your eyes to become dry, causing you to have trouble focusing clearly.

9. Protect against stress with Vitamin A.

Vitamin A may be able to help reduce stress on several levels. First, it may help your body stay calm. Vitamin A is also thought to lower the symptoms of depression that happen during times of stress. Another way it protects the body during stress is by aiding in the production of things that are needed to help your body deal with stress.

For example, vitamin A is needed to produce gamma-glutamylcarbinyl (GAC), an important neuro-transmitter that helps your nervous system function properly during stressful periods. The body also uses vitamin A to convert proline into gamma-aminobutyric acid (GABA). GABA is an inhibitory neurotransmitter that calms the highly reactive brain and nervous system.

This vitamin also helps increase the oxygen in our cells so that we can think more clearly when dealing with stress.

Vitamin A is able to regulate emotions such as fear, tension, anger, and even depression by increasing endorphin levels in the brain. Vitamin A increases the production of enkephalins and endorphins in the brain, which have a calming effect on us that is similar to morphine.

10. Vitamin A is an antihistamine and aids in allergy relief.

A surprising benefit of Vitamin A is that it acts as an antihistamine by inhibiting the release and synthesis of histamine from the cells. These histamines are responsible for allergic reactions. It does this by supporting your body’s natural antihistamine mechanisms.

Vitamin A is significant for your immune system because it supports the production of white blood cells that fight off infection and viruses. Therefore, it helps prevent allergy symptoms that are caused by these things (such as hay fever or asthma). The U.S. Institute of Medicine recommends getting about 1,400 IU of vitamin A daily for adults and children 9 years and older who are at risk for developing allergic conditions.

11. Reduces the risk of infection with Vitamin A.

Vitamin A is important for helping your body fight viral infections. It does this by activating your immune cells and supporting the production of infection-fighting white blood cells.

For example, studies have shown that children with severe vitamin A deficiencies are more likely to get ear infections because their immune systems aren’t working properly. Children who are deficient in vitamin A also appear to be at greater risk for getting lung infections like pneumonia.

12. Vitamin A is critical to children’s development.

Vitamin A is especially beneficial for children because it supports the growth of bones and teeth. It also helps to prevent night blindness, which is caused by problems with the development of rod cells in the eye. Vitamin A is also important for protecting children from rickets, or softening of the bones that occurs when they don’t get enough vitamin A early in life.

Children are also at greater risk for developing night blindness because they develop fewer rod and cone cells in their eyes when they’re growing. Vitamin A helps to keep these cells healthy and functioning properly so that your child has normal vision at night. It also helps the body to produce vitamin A more efficiently so that your child gets enough of this vitamin, even though they may not be getting enough from their food sources.

In addition, Vitamin A is also thought to support the health of the cells in the nervous system. This may help the brain to work properly, which is especially important while your child is growing.

13. Vitamin A supports brain function and vision.

Vitamin A is important for protecting your brain because it strengthens connections between brain cells (synapses). It does this by supporting a chemical in your brain (acetylcholine) that helps between cells communicate with each other.

In addition, Vitamin A also has antioxidant and anti-inflammatory properties, which help support the health of your brain.

14. Benefit of Vitamin A for beauty: Promotes healthy skin.

Vitamin A is important for keeping your skin moist and soft. It also aids in the formation of new skin cells, which keeps your skin from aging too quickly. It does this by stimulating the production of a protein called collagen. Collagen is what keeps your skin strong and helps it to repair any damage.

It is also important for healthy skin because it provides your body with all of the retinoic acid (AKA retinol) that it needs to make other important compounds.

15. Reduces the risk skin cancer and prevents sunburns.

Another surprising benefit of Vitamin A is that it helps to prevent skin cancer in many ways. For example, it may help protect against skin cancer by suppressing the growth of certain types of skin cancers. It does this by making sure your skin’s DNA remains intact, so you aren’t exposed to certain potentially damaging compounds in the environment.

Vitamin A also helps to protect against sunburns by creating new skin cells in your body, which are better able to fight off sun exposure.

This vitamin also helps your body produce sunscreens that protect you from the sun’s harmful rays. It does this by helping cells in your skin make vitamin D, which is necessary for making your body’s natural sunscreen (called melanin).

16. Vitamin A reduces the risk of heart disease and lowers bad cholesterol.

Here is an unexpected benefit of Vitamin A.. it is important for your heart because it helps to lower blood pressure, which may be helpful in preventing cardiovascular disease. Studies show that when you take vitamin A supplements, your blood pressure levels go down, and this can help reduce the risk of stroke. Vitamin A may also play a role in lowering the risk of developing cardiovascular disease by reducing inflammation in people who already have chronic conditions such as diabetes and high blood pressure.

Vitamin A increases HDL cholesterol by removing excess cholesterol from the blood via its antioxidant properties. It is important for helping your body remove cholesterol from the liver and other tissues in the body. It also helps to lower LDL cholesterol, which is a type of bad cholesterol that plays a vital role in heart disease.

HDL is beneficial for your heart because it helps to protect your arteries from oxidation that can eventually lead to heart disease.

Vitamin A also helps the walls of your arteries tighten up, which promotes a healthy cardiovascular system. Vitamin A does this by helping the cells in your blood vessels (called endothelial cells) remain healthy and protect your heart.

Also, Vitamin A also supports the health of your blood vessels by supporting their ability to relax, which reduces the workload on your heart.

Studies have shown that when people take a vitamin A supplement, they generally have more normal blood pressure levels and lower cholesterol levels than those who don’t take them.

17. Benefit of Vitamin A for diabetics: helps produce insulin.

Vitamin A has also been considered to be beneficial for people with diabetes and high blood sugar because it helps the pancreas produce more insulin when active. It does this by promoting the health of the cells in the pancreas that produce insulin.

Studies have shown that taking vitamin A supplements can help lower blood sugar levels for people with type 2 diabetes if you don’t get enough vitamin A from your diet. People who are deficient in vitamin A are more likely to have blood glucose problems.

And, Vitamin A also helps lower cholesterol and triglycerides in people with diabetes.

18. Vitamin A helps to digest food.

Vitamin A can also help you digest your food and absorb important vitamins and minerals. The protein we eat must be broken down into a form that your body can absorb. Vitamin A helps with this process by helping your body make an enzyme called trypsin that is needed to break down protein. Trypsin helps to break down the proteins in the food you eat so that they can be used by your body.

It also helps to keep the mucous membranes of your intestines healthy by protecting them from infection and irritation. In particular, it helps keep the large intestine (colon) working at an optimal level, which means better absorption of nutrients from food.

The takeaway

In conclusion, the many benefits of vitamin A means that it’s too important to your health not to take it very seriously.

It is also recommended that you get most of your vitamin A from food sources instead of supplements. This is because of the potential dangers that can come with taking large amounts of retinol (i.e. retinoic acid, which is a type of vitamin A that’s found in supplements). If you take large amounts of retinol in the form of supplements, you can end up storing it in your body fat instead. Large doses of retinol also can cause problems with your liver and kidneys.

What do you think? Is Vitamin A important for health? Should we supplement with Vitamin A or just get it from food sources?
