25 Vitamin A Foods That Will Boost Your Health
Just 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, so a balanced diet can provide us with a sufficient amount of this vitamin. However, some people have to take supplements for various medical reasons. On the other hand, it’s not recommended to take too much vitamin A as this can lead to some serious medical conditions. We at medalerthelp.org have prepared an infographic which provides you with a quick overview of all the vitamins, but now let’s focus on vitamin A.
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, which are found in 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 certain carotenoids found in fruits and vegetables, among which beta-carotene is the most important one.
What Is Vitamin A Good For?
It’s very important for your health to consume enough foods rich in vitamin A as it affects a number of organ systems of your body. First, it is vital for your eye health. It can prevent night blindness since it has a major role in converting light into electrical signals. People with this eyesight problem have difficulty in 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 to maintain a healthy immune system. Since it stimulates the production of white blood cells, which are 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.
Although skin problems, such as acne and wrinkles, are not that serious, they make us feel less confident and even anxious and depressed. Fortunately, your skin can also benefit from this vitamin. Beta-carotene is a potent antioxidant which 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 is proven that it stimulates collagen production. Vitamin A is also used for the treatment of severe acne although it is still unclear how it lowers the risk of developing this skin condition.
According to a number of studies conducted on rats, 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 the level of blood sugar in mice.
Foods High in Vitamin A
As we already mentioned, there are two types of vitamin A and they can be found in different types of food. Animal products contain preformed vitamin A or retinol. On the other hand, provitamin A carotenoids, which are transformed into vitamin A through metabolic processes, are actually pigments that make 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.
If you’ve been wondering what foods have vitamin A, you’re in the right place. Since retinol is stored in the liver, this is the number one food for your source of this healthy nutrient.

Daily Intake Recommendations
Recommended dietary allowance (RDA) represents an average daily intake that is sufficient to 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 sources of vitamin A, this practice is soon to be changed thanks to FDA’s new labeling regulations.
The recommended daily intake of vitamin A depends on your age and sex, 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
- 14+ years – 900 mcg RAE (male) and 700 mcg RAE (female)
RDAs for vitamin A are a bit different for pregnant women (770 mcg RAE) and women who are breastfeeding (1300 mcg RAE).
Signs & Symptoms of Vitamin A Deficiency
Although this deficiency is rare in developed countries, it is prevalent in developing countries where people usually don’t have enough foods rich in vitamin A. 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. This is an eye disease characterized by dryness of the conjunctiva and cornea. Deficiency of vitamin A 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 infective diseases, such as diarrhea and measles.
Who Should Take Vitamin A Supplements?
Groups that are at higher risk of vitamin A deficiency include premature infants, infants, and children in developing countries, pregnant and breastfeeding women in developing countries, and people with cystic fibrosis. Also, certain medications, such as Orlistat, can affect the body’s ability to absorb fat-soluble vitamins and therefore increase the risk of vitamin deficiency.
Those who lack vitamin A can take vitamin A tablets, but they should always consult a physician first. You should be aware that there are a number of side effects of taking vitamin supplements. In addition, there’s a possibility that they will cover up other deficiencies, which can result in some serious health issues. That’s why it’s always best to rely on vitamin A foods in order to meet your daily requirements of this vitamin. While vitamin supplements can do good to certain groups of people, taking excessive amounts or taking them for too long can be harmful.
Can You Overdose on Vitamin A?
The body tends to store fat-soluble vitamins, meaning that excess consumption of vitamin A can be toxic. Preformed vitamin A is particularly dangerous as it can cause hypervitaminosis A. Overconsumption of vitamin A can lead to skin irritation, dizziness, nausea, headaches, joint pain, and even death.
So how much vitamin A is too much? The Food and Nutrition Board has prescribed Tolerable Upper Intake Levels for preformed vitamin, which vary according to age and sex. For adults, total vitamin A intake should be up to 3,000 µg per day from retinol. Pregnant women should be particularly careful 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 vitamin A supplements. Compared to preformed vitamin A, carotenoids are not that toxic, especially when consumed through food. 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. It has a number of important roles in our body, from maintaining healthy vision to reducing the risk of certain cancers and heart disease. Therefore, it’s very important that your daily intake of this vitamin is at the optimal level. Remember that both too little and too much of vitamin A can lead to serious health conditions. You should try to follow a balanced diet that includes various foods rich in this vitamin as this is the best option for your health. Of course, vitamin supplements can be beneficial for some people, but in general you should avoid taking them.
What does vitamin A do in the human body?
Vitamin A is responsible for the normal functioning of a number of organs, including the heart, lungs, kidneys, and the reproductive system. It is essential for normal vision and strong immune system.
What are the benefits of taking vitamin A?
A recommended daily intake of vitamin A will protect you from night blindness, keep your bones healthy, and boost your immune system. It may even reduce the risk of certain cancers, such as lung or prostate cancer. Just remember that it’s always best to include foods rich in this vitamin in your diet instead of relying on supplements.
What does vitamin A do to your face?
This vitamin has been successfully used in the treatment of acne. In addition, various face creams contain retinol as this ingredient helps in the fight against wrinkles. Consuming fruit and vegetables rich in beta-carotene can make your skin less prone to UV damage.
Which fruits are rich in vitamin A?
Fruits contain vitamin A in the form of carotenoids, which are actually yellow, orange, and red pigments. Therefore, fruits in these colors are high in vitamin A. The list includes apricots (fresh and dried), passion fruit, red or pink grapefruit, mangoes, tangerines, and nectarines.
What are side effects of vitamin A?
High doses of this vitamin may cause adverse side effects, such as nausea, vomiting, irritability, fatigue, headaches, and many more. It can even lead to coma or death.
