28 Vitamin A Foods That Will Boost Your Health
Like all the other vitamins, vitamin A plays a crucial role in the normal growth and development of the body. There are a number of vitamin A foods, and a balanced diet can provide us with a sufficient amount of this vitamin. However, some people have to take supplements for various medical reasons. Also, it’s not recommended to take too much vitamin A as this can lead to some severe medical conditions. We have prepared some interesting data on vitamin A, so let’s dive in.
What Is Vitamin A?
Vitamin A is an umbrella term for a group of oil-soluble compounds essential for the proper functioning of your eyes, skin, reproductive system, and many other processes in your body. It comes in two different forms—preformed vitamin A and provitamin A.
Preformed vitamin A includes retinol, retinal, and retinoic acid, and some of the foods that contain retinol are animal products. The body doesn’t have to convert this type of vitamin A before it uses it, and that’s why it’s also called the active form of vitamin A.
Provitamin A, on the other hand, has to be converted to active vitamin A once it is found in the body. It includes specific carotenoids found in fruits and vegetables, among which beta-carotene is the most important one.
What Is Vitamin A Good For?
It’s vital to consume enough foods rich in this vitamin as it affects many organs and systems in your body.
First, many people turn to vitamin A foods for eye health. Notably, the vitamin can prevent night blindness since it plays a significant role in converting light into electrical signals. People with this eyesight problem have difficulty adjusting to dim light, while their vision is not impaired when there is enough light. Also, beta-carotene lowers the risk of developing age-related macular degeneration.
Another vitamin A function is maintaining a healthy immune system. Since it stimulates the production of white blood cells responsible for fighting viruses, bacteria, and other foreign invaders, it can help your body resist infections. In line with this, recent studies have shown that vitamin A can reduce the risk of dying from measles.
Now, when it comes to the skin, what cannot be downplayed is the impact of vitamin A. Acne, for instance, could be reduced with its help. On top of that, there is beta-carotene, a potent antioxidant that can protect your skin from UV damage and slow down the signs of aging. In addition to eating foods containing this compound, you can use creams with retinol or retinoic acid.
So, what does topical vitamin A do for your skin? It can fill in your fine lines and smoothen your skin as it stimulates collagen production. Vitamin A is also used to treat severe acne, although it is still unclear how it lowers the risk of developing this skin condition.
According to several studies on reproduction, vitamin A is vital for the reproductive system of both men and women, as well as for the normal development of embryos. Other vitamin A benefits include maintaining healthy bones and lowering the risk of certain types of cancer. According to some studies, one derivative of vitamin A, retinoic acid, regulates blood sugar levels in mice.
Vitamin A Foods
As we already mentioned, there are two types of vitamin A, and they can be found in different kinds of food. Some of the food with vitamin A are animal products containing preformed vitamin A or retinol.
Interestingly, provitamin A carotenoids, which are transformed into vitamin A through metabolic processes, are actually the pigments that make vitamin A fruits and vegetables orange.
Considering all the health benefits of this vitamin, it’s of great importance to include the following foods in your diet. Let’s see what foods could supply you with much-needed vitamin A.
If you love eating fish and you have been wondering what foods are high in vitamin A, you’re in the right place.

Vitamin A Recommended Intake
Recommended dietary allowance (RDA) represents an average daily intake that is sufficient for healthy people to meet their nutrient requirements. RDAs for vitamin A are expressed in mcg of retinol activity equivalents (RAE), although international units (IU) are used on food and supplement labels. Since the conversion of mcg RAE into IU is rather complex as it depends on the vitamin A food sources chart, this practice will soon be changed thanks to the FDA’s new labeling regulations.
The recommended daily intake of vitamin A is as follows:
- from birth to 6 months—400 mcg RAE
- from 7 to 12 months—500 mcg RAE
- from 1 to 3 years—300 mcg RAE
- from 4 to 8 years—400 mcg RAE
- from 9 to 13 years—600 mcg RAE
- teen boys 14–18 years—900 mcg RAE
- teen girls 14–18 years—700 mcg RAE
- adult men—900 mcg RAE
- adult women—700 mcg RAE
Vitamin A recommended daily intake is a bit different for pregnant women aged 19–50 (770 mcg RAE). Also, it’s different for women who are breastfeeding (1300 mcg RAE).
Vitamin A Deficiency Symptoms and Signs
Although this deficiency is rare in developed countries, it is prevalent in developing countries where people usually don’t have enough vitamin A food. So what is the first sign of vitamin A deficiency? The most common symptom is night blindness, which is one of the first signs of xerophthalmia.
In a nutshell, it is an eye disease characterized by dryness of the conjunctiva and cornea. Vitamin A deficiency can also cause preventable blindness in children. What’s more, it can lead to anemia since people deficient in vitamin A often have low iron levels. Another serious consequence is the increased mortality risk of infectious diseases.
Who Should Take Vitamin A Supplements?
Demographics at higher risk of lack of vitamin A include:
- premature infants
- children in developing countries
- pregnant and breastfeeding women in developing countries
- people with cystic fibrosis
Also, certain medications, such as Orlistat, can affect the body’s ability to absorb fat-soluble vitamins and increase the risk of vitamin deficiency.
Those who lack vitamin A can take vitamin A tablets, but they should always consult a physician first. A healthcare professional will determine the dosage necessary to address the vitamin deficiency.
Can You Overdose on Vitamin A?
Excess consumption of vitamin A can be toxic. Preformed vitamin A is particularly dangerous as it can cause hypervitaminosis. Overconsumption of vitamin A can lead to:
- skin irritation
- joint pain
So how much vitamin A is too much? The Food and Nutrition Board has prescribed Tolerable Upper Intake Levels for the preformed vitamin, which vary by age and sex. The tolerable upper daily vitamin A intake should be 3,000 µg of preformed Vitamin A per day for adults. Pregnant women should be particularly cautious as excess retinol can result in fetal deformities. They should also avoid using anti-aging creams containing this compound.
Moreover, people using certain drugs for acne treatment need to stay away from supplements of vitamin A. Compared to preformed vitamin A, carotenoids are not that toxic, especially when consumed through food, as vitamin A nutrition facts confirm. However, beta-carotene supplements can cause some adverse effects. That’s why it’s of great importance to stick to a recommended vitamin A dosage.
Vitamin A is one of the essential nutrients that we need to stay healthy, and it is found in many foods, as the vitamin A foods chart shows. It plays a critical role in our body, from maintaining healthy vision to reducing the risk of certain diseases. Therefore, your daily intake of this vitamin must be at an optimal level.
Remember that both too little and too much vitamin A intake can lead to severe health complications. It would help if you tried to follow a balanced diet that includes various foods rich in this vitamin.
