Vitamin A is an essential nutrient for the maintenance of good health. It helps maintain vision, skin, and mucous membranes. Vitamin A also helps your immune system fight infections.
Vitamin A is found in animal products such as fish, beef, and poultry; yellow, orange, and dark green vegetables; egg yolks; fortified dairy products like milk or yogurt; fortified cereals like Cheerios (which are made with brown rice); and some fruits such as cantaloupe melon or papaya fruit (notably not watermelon).
While there are no recommended dietary intake levels set by Health Canada for vitamin A supplements per se (there are recommendations regarding how much retinol should be consumed daily), if you have been diagnosed with a deficiency or have an increased need due to illness or pregnancy/lactation then you may want to talk with your doctor about taking a supplement containing vitamin A alone or in combination with other vitamins such as E & D3
Vitamin A is a fat-soluble vitamin that plays an important role in many body functions.
Vitamin A is a fat-soluble vitamin that plays an important role in many body functions. It's involved in vision, skin health, the immune system, growth and development (especially during pregnancy), reproduction, and more.
Vitamin A can be found naturally in foods such as meat, shellfish, eggs, and dairy products. It's also added to some foods like breakfast cereals or juices.
The body cannot make vitamin A, so it must come from food sources.
Vitamin A is a fat-soluble vitamin. This means it can't be stored in the body and needs to be consumed on a regular basis. Vitamin A is found in meat sources such as fish, beef, and poultry; however vegetables containing high levels of beta-carotene are also excellent sources of vitamin A. Retinol and retinyl esters are forms of vitamin A, while retinaldehyde (RALDH2) catalyzes the conversion from retinol to retinoic acid which is responsible for cellular differentiation during embryonic development or tissue regeneration after injury.[1]
Many people get enough vitamin A from their diet without supplementing with additional amounts through foods or supplements.[2] However, if you do need extra supplementation there are many options available including liquid drops under the tongue (sublingual), pills taken orally with water once daily before bedtime

Vitamin A is fat-soluble, so it can be stored in the body for long periods of time. This means that you don't have to worry about getting too much vitamin A if you eat large amounts of food containing this nutrient. If you consume more than the recommended daily allowance (RDA), however, some may be stored as excess fat deposits on your body or liver cells (hepatocytes). Be sure not to exceed the RDA--which varies depending on age and gender--and consult with your doctor before starting any new supplement regimen!
Vitamin A is water soluble; therefore excess amounts will be excreted through urine rather than stored in fatty tissues like most other vitamins do when ingested beyond what's needed by our bodies' needs at any given time or situation."
Vitamin A is found in meat sources such as fish, beef, and poultry.
Vitamin A is found in meat sources such as fish, beef, and poultry. Vitamin A is also found in vegetables such as carrots, spinach, and kale. This vitamin can be stored in the liver for up to 2 months so you don't need to eat it every day to get enough of this nutrient.
If you've got a deficiency of vitamin A, you may experience symptoms such as weakness and fatigue because it helps with healthy skin, hair, and nails too!
Vegetables containing high levels of beta-carotene are also excellent sources of vitamin A.
- Vegetables containing high levels of beta-carotene are also excellent sources of vitamin A.
- Beta-carotene is converted to vitamin A in the body, but not as well absorbed as retinol.
- Beta-carotene can be used to treat certain conditions such as night blindness and xerophthalmia (dry eyes). Vitamin A helps form and maintain healthy skin, teeth, and skeletal and soft tissue (such as mucus membranes), as well as promotes good vision, especially in low light conditions by promoting the production of rhodopsin (the pigment responsible for detecting light) in the retina of your eye.
There are two forms of vitamin A, retinol and retinyl esters, which are found in animal products and plants respectively.
There are two forms of vitamin A, retinol and retinyl esters, which are found in animal products and plants respectively. Retinol is easily absorbed by the body and can be found in milk, cheese, eggs, and butter. It's also available as a dietary supplement in tablets or capsules containing vitamin A palmitate (vitamin A bound to palmitic acid), which is more easily absorbed by the body than beta-carotene.
Vitamin A helps to form bone tissue and keeps your skin healthy by keeping oil production under control on your face while also moisturizing it from within so you don't have dry patches on top of wrinkles!
Takeaway:
Vitamin A is an essential nutrient for the maintenance of good health. It plays an important role in many body functions, including vision and cell growth. The body cannot make vitamin A so it must come from food sources. Many people get enough vitamin A from their diets, however, some groups may need to take a supplement such as pregnant women or those who have liver disease or ulcers on their stomach lining (peptic ulcer).
Vitamin A is found in meat sources such as fish, beef, and poultry; vegetables containing high levels of beta-carotene are also excellent sources of vitamin A such as carrots and sweet potatoes.
Conclusion
While many people get enough vitamin A from their diets, some groups may need to take a supplement. Vegans and vegetarians should consider taking a multivitamin with vitamin A since this nutrient is not found in plant foods. If you are concerned about your intake of vitamin A or other nutrients, talk with your doctor about testing options available at your local health clinic.
