Seven health benefits of vitamin A

Seven health benefits of vitamin A

While known as the vitamin for the eyes, the benefits of vitamin A for the body is diverse. The vitamin A group can be sourced in Animal products, including dairy and meat, and various plant-based foods, fruits, and vegetables, such as carrots. “Vitamin A” can be misguiding term, as it can be easily confused for a single nutrient, while it refers to a group of fat-soluble compounds such as retinol, retinal, and retinyl esters.

We cannot avoid these nutrients when aiming for a robust and functioning system, as they are essential to many processes. We depend on vitamin A to maintain a healthy vision, a well-performing immune system, and natural cell growth. This vitamin is also crucial for healthy embryo development and growth in the womb.

Vitamin A forms and fat solubility

Vitamin A is fat-soluble, meaning it can dissolve in fat and oils. These kinds of vitamins can be stored in the body’s fatty tissues and liver. Animal products are a staple of first-world diets. Therefore vitamin A deficiency is not very common in developed countries. But with fat-soluble nutrients, there is a chance of build-up. So, to prevent health problems, it is recommended that we consume them in small doses.

The recommended daily value of vitamin A for women is 700mg. It goes up to 900mg for men; both of which can be easily sustained with minimal attention to the diet.

But for people with a very appetite, those who do not consume animal products, or anyone who enjoys a more plant-based diet, supplements are an accessible alternative, comfortably adaptable to a modern lifestyle. The vitamin A in Sanbera tablets is enough to resolve your body’s needs without leaving you with excess build-up.

Vitamin A can be categorized into two main groups; preformed vitamin A and provitamin A. Preformed vitamin A includes retinol and retinyl esters and can only exclusively be sourced in animal products such as dairy, liver, and fish. On the other hand, provitamin A carotenoids are generously available in plant foods, such as fruits, vegetables, and oils. This is the kind of vegan-friendly vitamin A compound present in our Daily Essential Women and Daily Essential Men supplements.

Both of these are then converted by the body to their active forms, retinal and retinoic acid. The excess is kept in the liver as retinyl esters. The ester will then enter the bloodstream and binds to retinol-binding protein which can be used by the body.

Eye health

Upon hearing “Vitamin A”, eye health instantly pops into mind. The compounds are essential for colour and low-light vision. Retinal, the active form, binds with opsin proteins to create rhodopsin, a molecule required for accurate colour identification and the ability to see at night. This molecule is essential in protecting the outer layer of your eyes and the membrane, which covers the surface, and insides of the eyelid.

Rhodopsin translates the light into electrical signals that the brain can read. That is why, in many cases, one of the early signs of vitamin A deficiency is night blindness.

Research shows that plant-based vitamin A, beta—carotene, can help decrease the speed of eye-sight decline, which is a condition associated with aging. The leading cause of blindness in developed countries is age-related macular degeneration. While the cause is uncertain, it is thought to be a result of retina cellular damage due to oxidative stress.

According to the Age-Related Eye Disease Study, people over the age of 50 who were supplied with antioxidant supplements, such as beta-carotene, were 25% less likely to experience advanced macular degeneration.

Robust immune system

Vitamin A is essential in maintaining the epithelial tissue. This tissue builds the surface of your internal and external organs, including your nose, throat, genitals, lungs, and digestive tract, forming your first line of defence against outside threats.

Vitamin A is also necessary for white blood cell production, which protects your body against infections and bacteria, meaning that suboptimal vitamin A status will lead to slower recovery and a higher chance of sickness. Studies in underdeveloped countries have proven that correcting vitamin A deficiency decreases the risk of death in children suffering from bacterial infections such as malaria and improves recovery.

Lower risk of cancer

Because of vitamin A’s role in cell production and growth, its complex relationship with cancer has been in the spotlight. The exact manner in which vitamin A affects cancer is still not completely clear to researchers. But many believe that the glorious reds, oranges, and greens in beta-carotene-dense fruits prevent unhealthy cell growth. Several observational studies show a link between beta-carotene consumption and a lower risk of certain cancers, including Hodgkin’s lymphoma and cervical, lung, and bladder cancer.

In addition to increasing antioxidant intake, beta-carotene also initiates antitumor activity. But on the other hand, vitamin A sourced from animal products does not have the same effect. Furthermore, some studies discovered that high vitamin A intake in smokers, or even people with a history of smoking, leads to a higher chance of lung cancer. Therefore, if you have a history of smoking, it is best to contact your doctor before taking any vitamin A supplements.

Vitamin A supplements do not seem to lower the chance of cancer in people without vitamin A deficiency. But they seem to benefit cases with suboptimal vitamin A status.

Overall health

Vitamin A’s part in cell production and growth makes it essential to our overall health. All the organs are dependent on this vitamin to keep functioning and healing. It is necessary for the growth and cell reproduction of every organ, including the heart, the lungs, and the digestive tract.

Relations have been found between vitamin A deficiency and lung diseases such as asthma, showing its importance for healthy lung function.

Bone health

As children, we were taught to drink milk to have healthy bones. Vitamin A is necessary for all cell growth, including the ones that build your bones. But while vitamin A in milk benefits bone growth, it also affects the cells responsible for recycling and breaking down the bones.

Vitamin A deficiency is connected to increased bone fracture risk. But vitamin A buildup also seemingly negatively impacts bone health, making them more vulnerable. The negative impacts of vitamin A depend on many other factors, including the balance of other bone-building nutrients like vitamin D. Nevertheless, scientists believe that animal products should be limited in any diet to prevent accumulation.

Keep in mind that the relationship between bone health and vitamin A is still not completely understood. More research is necessary to determine who may benefit from additional vitamin A supplements.

Vitamin A helps with acne.

Studies show that sub-optimal vitamin A status can lead to acne, as it is connected to keratin over-production and the blockage of sebaceous glands. Experts also believe that vitamin A has a part in exfoliating dead cells, and allowing the skin to breathe.

As vitamin A boosts antioxidant intake, consuming a beta-carotene-rich diet leads to a brighter complexion and protection against free radicals. Almost everyone  experiences improved skin after a while with our Daily Essential Women and Daily Essential Men supplements, partly due to its vitamin A properties and bioavailability.

Healthy reproduction

Considering vitamin A’s cell-building role, it becomes clear that it should also be vital for healthful reproduction in men and women, as for the natural development of embryos during pregnancy.

Animal research shows that vitamin A insufficiency blocks the development of sperm cells and affects egg quality in women and egg fertilization. The natural growth and development of the embryo’s organs are also connected to the mother’s vitamin A adequacy. Vitamin A deficiency during preconception or the early stages of embryo development might induce altered gene expression and affect the baby’s heart.

On the other hand, while far less common, vitamin A overconsumption might harm the baby and cause birth defects. This is why some scientists recommend pregnant women eat plant-based foods to supply their daily vitamin A needs and avoid animal products that are dense in vitamin A, such as the liver.

If you are pregnant or planning to become pregnant soon, it is best to consult your doctor before taking supplements that carry vitamin A, including Sanbera products.


Vitamin A is a group of nutrient compounds vital for the body. This group of nutrients is abundant in animal products and present in many plant-based foods. It can be traced by the bold reds, oranges, and greens in the vegetables and fruits around us.

One of the most important roles of vitamin A in the body is cell production and growth, making it crucial to all organs. Vitamin A is necessary for a robust immune system, strong bones, and clear skin. Vitamin A deficiency is believed to be linked to various cancers and unhealthy embryo development.

But as the vitamin A group is fat soluble, it is stored in the liver and the fatty tissues of the body and can lead to a build-up. Too much vitamin A can increase the chances of bone fracture and motivate birth defects in pregnant women.

Vitamin A overconsumption is rare with plant-based diets. It usually occurs with diets where a lot of vitamin-A-dense animal products are eaten, or through supplement overconsumption.
