How we pick our products
Vitamin A is an essential nutrient that is essential for many processes in your body, including maintaining healthy vision, ensuring the normal function of your immune system and organs and aiding the proper growth and development of babies in the womb.
Vitamin A cannot be made by the human body and so it is an essential part of the diet. Vitamin A is important for healthy eyes, good eyesight (vision), healthy skin and to help you fight infections. It is also sometimes also called retinol. While vitamin A deficiency is not often seen in developed countries, people who partake in extreme weight-loss diets can become deficient.

Shopping Guide: Everything you should know about vitamin A
Vitamin A is an essential nutrient for healthy vision, teeth, skeletal tissue, and skin. It can be found in natural food sources such as carrots. There are two types of vitamin A: preformed vitamin A, also called retinol, is found in animal products such as milk, eggs, meat, and cheese, Pro-vitamin A is found in plant-based foods such as fruits and vegetables.
What is vitamin A exactly?
Beta-carotene is the most important for vitamin A synthesis. The human body converts beta carotene into vitamin A (retinol), so essentially it is a precursor of vitamin A. We need vitamin A for healthy skin and mucus membranes, our immune system, and good eye health and vision. Beta carotene in itself is not an essential nutrient, but vitamin A is.
Vitamin A can be found in the food we eat, through beta carotene, for example, or in supplement form. The advantage of getting our beta carotene from our food is that the body only converts as much as it needs.
How does vitamin A help my body?
|Visual||Normal vision. Vision in low-light conditions|
|Muscular||Creation of new cells|
|Cardiovascular||Creation of defensive cells|
|Immune||Activation of the defensive system. Creation of immune cells|
|Nervous||Preservation of ordinary memory|
|Hormonal and ageing||Antioxidant (beta-carotenes)|
What is the recommended dose of vitamin A?
Remember: 1 mcg of retinol is equal to 1 mcg of RAE, and 12 mcg of beta-carotene are equal to 1 mcg of RAE.
|Population group||RAE daily dose (mcg)|
|Babies 0-6 months||400|
|Babies 7-12 months||500|
|Children 1-3 years||300|
|Children 4-8 years||400|
|Adolescents 9-13 years||600|
|Women over 13||700|
|Men over 13||700|
What foods are rich in vitamin A?
|Food||Quantity of vitamin A (mcg)||% of the Recommended Daily Dose|
|Veal liver (100 g)||9,442||1,000%|
|Lamb liver (100 g)||7,500||800%|
|Cod liver oil (1 tablespoon)||1,350||150%|
|Mackerel (100 g)||252||28%|
|Camembert (cheese) (100 g)||240||27%|
|Salmon (100 g)||150||17%|
|Foie gras (1 tablespoon)||130||14%|
|Butter (1 tablespoon)||100||11%|
|Egg (1 XL egg)||75||9%|
Recommended dietary allowance (RDA) represents an average daily intake that is sufficient to healthy people to meet their nutrient requirements. 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 foods are rich in beta-carotene?
|Food||Quantity of beta-carotene (mcg)||RAE equivalence (mcg)||% of the Recommended Daily Dose|
|Pumpkin (100 g)||3,123||260||29%|
|Canary melon (100 g)||1,190||99||11%|
|Lettuce (100 g)||800||67||7%|
|Red capsicum (100 g)||686||57||6%|
|Apricot (100 g)||565||47||5%|
|Broccoli (100 g)||483||40||4%|
|Peas (100 g)||405||35||3%|
You can easily calculate the quantity of vitamin A found in a beta-carotene-rich food: all you have to do is divide the micrograms of provitamin A by 12. The value obtained corresponds to the “Retinol Activity Equivalents” (RAE), which indicate the amount of vitamin A that you’ll get after metabolising beta-carotene.
Nowadays, our diet tends to be rich in meat and fatty products, but poor in foods of plant origin. Don’t forget that beta-carotene isn’t the only thing you’ll get from fruits and vegetables: fibres, antioxidant elements and other vitamins are some of the other benefits present in foods of plant origin.
Who is affected by vitamin A deficiency?
Vitamin A deficiency can result from inadequate intake, fat malabsorption, or liver disorders. While deficiency is rare in developed countries, many people in developing countries do not get enough vitamin A. Those at highest risk of deficiency are pregnant women, breastfeeding mothers, infants and children. Cystic fibrosis and chronic diarrhoea may also increase your risk of deficiency.
Vitamin A deficits can be provoked by certain diseases that affect proper nutrient absorption. Crohn’s disease, cirrhosis and sprue, for instance, will lead to retinol deficiencies if they are not treated properly. If you suffer from vitamin deficiency despite having a balanced diet, please consult a doctor.
How does vitamin A deficiency manifest itself?
- Dry skin and hair
- Unexplained itching or stinging all over the body
- Difficulty healing wounds
- Loss of night vision
- Blurred vision
- Severe vision disturbances, such as corneal ulcers
- Frequent infections, especially flu and gastroenteritis
- Infertility, miscarriages, and foetal growth failure
- Frequent bone fractures
- Lack of appetite

Vitamin A or beta-carotene supplements: which are better??
Your body can also convert beta-carotene from plant-derived foods into vitamin A when needed. Beta-carotene may also have other benefits, in addition to being a precursor for vitamin A. Beta-carotene is called a provitamin A carotenoid because your body can convert it to active vitamin A.
This is why we encourage you to supplement with beta-carotene if you want to increase your vitamin A levels. While this substance is naturally not flawless (for instance, use by smokers is contraindicated), it is considered much safer. You will also reap extra benefits from its antioxidant and photoprotective properties.
Who should take beta-carotene supplements?
- People with age-related macular degeneration (AMD)
- People with skin that burns very easily in the sun
- People on low-calorie, nutrient-poor diets
- People with very dry skin and brittle hair
While vitamin A can make your skin more sensitive to the action of the sun, beta-carotene will protect it. This substance seems to combat the ageing effect of sun exposure on your skin. Certain individuals also use it for purely aesthetic purposes, as it contributes to a prolonged tan.
What caution should I exercise with beta-carotene?
Eating foods rich in beta-carotene, along with other antioxidants, including vitamins C and E, seems to protect against some forms of cancer. However, beta-carotene supplements may increase the risk of heart disease and cancer in people who smoke or drink heavily. Those people should not take beta-carotene, except under a doctor’s supervision.
In a nutshell, beta-carotene supplements are generally considered safe, although smokers should avoid them. Pregnant women must check with their healthcare provider prior to trying them. When compared to supplements, foods rich in beta-carotene present no side effects and are recommended for everyone.
With all of the different types of supplements available, it can be difficult to know which is the best for you. There are a few different aspects to consider when purchasing Vitamin A supplements, and not all are the same. To make it easier for you, we have created this shopping guide with all of the different elements to consider before you make your purchase. These shopping criteria will be key in your decision:
- Vegan or vegetarian nutrition
- Pharmacological interactions
- Recommended daily dose
- Value for money
A person can be allergic to almost any food. While allergies to carotenoids are rare, there have been reports of allergic reactions to the components of these gelatine capsules. Please be careful when buying such products if you are allergic to bovine proteins, soy or fish.
Vegan or vegetarian nutrition
As you know, beta-carotene comes from plant sources; but this doesn’t mean that its supplements are necessarily suitable for vegan individuals. As soft capsules containing the supplement are often made from bovine gelatin, it is recommended to carefully check the packaging of any product you’re interested in. Made from cellulose instead of gelatine, plant-coated capsules are also available on the market.
Herbs, vitamins, and other dietary supplements may augment or antagonise the actions of prescription and nonprescription drugs. Even supplements that do not have a documented pharmacologic action can affect the absorption, metabolism, and disposition of other drugs. Consult your doctor of pharmacist before taking them, especially if you follow a treatment to lower your cholesterol levels.
Recommended daily dose
Keep in mind that each individual has different vitamin A needs, and there are several different dosing options available. We encourage you to use the table found in our article to calculate your daily retinol needs. Remember that excessive supplementation will increase risks of side effects.
Value for money
You should not be taking vitamin a supplements for a long time. Typically, the maximum period for these types of supplements is three months. You will usually find most bottles with 30 to 60 capsules. The price can vary between C$15 and C$40, depending on the manufacturer. Some products containing additives, such as vitamin E, will be more expensive.
Vitamin A is essential for bodies. We can get it from the food we eat, as well as from supplements. It is essential for many functions in our body including maintaining healthy vision, strengthening our immune system and even aiding the growth and development of babies in the womb.
Though a deficiency is not common in Canada, pregnant women and those in developing countries are most at risk of vitamin a deficiency.The best way to ensure an adequate nutrient intake is to eat a varied and balanced diet, full of fruits, vegetables, whole grains, healthful fats, and lean proteins.
