It increases bone strength.
It improves vision and eye health.
Vitamin A is an antioxidant that helps fight free radicals and leaves the skin feeling younger and healthier.
The benefits of this vitamin go beyond what we can write here, so you could definitely research this particular vitamin further to find out more! But one thing is for sure, Vitamin A is good for your health.
Vitamin A helps to keep the skin healthy and clear by regulating the cell turnover rate of skin cells, which means it can help to fade blemishes and fight acne. It also maintains the moisture content of the skin by stimulating the production of sebum, an oily substance that helps to trap moisture.
Can you get too much Vitamin A? Yes! Although Vitamin A is extremely important for good health, getting too much of it can cause serious problems. There are two types of overdose that could occur with Vitamin A: acute or chronic.
Acute overdoses happen abruptly over a short period of time and the person overdosing will experience symptoms such as nausea, vomiting, diarrhea, and abdominal pain. Chronic overdoses happen over a long period of time and the person overdosing will experience symptoms such as headaches, fatigue, loss of appetite, irritability, and dry skin.
People who eat a lot of liver are at risk for Vitamin A toxicity because it is very high in Vitamin A. It is not recommended that adults should eat more than one serving of liver (3.5 ounces) per week.
There are also various medications that may cause Vitamin A toxicity like oral contraceptives, cholesterol-lowering medicines, beta carotene supplements, and other blood pressure or HIV/AIDS medications. Talk to your doctor if you are prescribed any medication for any condition and you want to know if it is safe to take with your multivitamins.
The best way to avoid overdosing on Vitamin A is by taking a daily multivitamin/mineral supplement that only contains the recommended amount. If you are already following a vitamin routine, continue taking your supplements according to the instructions but make sure you update the current supplement with all your new supplements. Follow this process every time you take on a new vitamin supplement.
From simple health issues like eye problems to serious birth defects, Vitamin A deficiency can be lethal for some people. It is one of the top nutritional concerns in third world countries where malnutrition is very common because of poverty and access to food. In America, Vitamin A deficiency is very uncommon so taking a multivitamin every day is not as important as it is for someone who doesn’t have access to food.
Vitamin a dosage:
Vitamin A is an important source in the body and is used for several functions. This vitamin is found in fish which can be consumed in the form of oil and in carrots.
The recommended dose of Vitamin A per day is between 800-900 micrograms (3,000 IU) for adult men and 700-800 micrograms (2,500 IU) for women. The maximum amount that should be taken by a person at one time has not been determined. However, it’s always better to take this vitamin after consulting your doctor to avoid any complications related to its overdose.
There are two forms of Vitamin A supplements: retinol derivatives, which have lower toxicity levels than carotenoids, and carotenoids, which do not increase the risk of birth defects. Vitamin A belongs to a group of chemicals known as retinoids. The most common version of vitamin A is retinol, which helps convert light into nerve impulses in the eye.

Retinyl palmitate is converted into retinoic acid when it comes in contact with skin cells and provides anti-aging effects on skin and reduces wrinkles. This form of Vitamin A does not irritate the skin but may cause a mild stinging sensation in the eyes if it gets into them accidentally. Retinyl palmitate cream/ointment is used to treat skin blemishes, roughness, dryness, and other signs of aging.
Retinyl palmitate cream may be unsafe to use during pregnancy. Animal studies have shown adverse effects on the fetus, however, there are limited human studies. The benefits of using retinol cream may be acceptable despite its risk. Please consult your doctor. Vitamin A Intensive Cream by SkinCeuticals 30ml
A carotenoid is a form of vitamin A that is obtained naturally from plants and does not cause any side effects, unlike retinol derivatives that can produce painful reactions in the eyes if it comes into contact with them. It should also not be taken orally as this can lead to toxicity in the body which can damage the liver and may even be fatal.
Carotenoid is present in sweet potatoes, carrots, broccoli, and spinach. It helps to protect the skin from sun damage as well as improve eye function. Carotenoid cream can be used as a night cream or sunscreen. Vitamin A Cream by Neutrogena 0 1 35 Fl Oz
Retinol is a form of vitamin A that helps improve signs of aging on the skin such as fine lines and wrinkles, firmness, and uneven texture without significant irritation. This vitamin should not be taken orally as this can lead to toxicity in body which can damage the liver and may even be fatal.
Retinol creams are safe for pregnant women but only after consulting with your doctor about their safety. However, dermatologists still advise avoiding using retinol during pregnancy because it may cause harm to the unborn baby.
Retin-A is one of the best known products containing this vitamin, which helps treat acne and improve signs of aging by increasing the formation of collagen in skin cells. Side effects include redness, scaling, stinging, or burning sensation for which you should take a lower dose initially and gradually increase the dosage under medical supervision.
Vitamin a food:
Foods that contain vitamin A include fish, liver, and dairy products. Foods like carrots and sweet potatoes are good sources of dietary beta-carotene which is a type of vitamin A.
Pregnant women should also take care as too much vitamin A can lead to birth defects in unborn babies. People who have liver cancer or diabetes shouldn’t take this Vitamin supplement as it might worsen the condition.
Don’t stay indoors on sunny days and apply sunscreen before going out for long hours as UV rays from the sun can cause skin damage even if you don’t burn easily at first. Taking vitamin supplements may help your body get more vitamins and minerals than what you normally eat but they won’t prevent sun damage completely so protect yourself with sunscreen lotion or lip balm that has SPF 15 or more.

Some creams with retinol derivatives may be unsafe to use during pregnancy as they can cause harm to an unborn baby. However, there are herbal remedies that contain carotenoids that provide similar benefits without side effects such as irritation on the skin. Consult your doctor before using any Vitamin A cream during pregnancy.
Benefits of vitamin a for the skin:
Retinol is the purest form of vitamin A which can be used to treat acne and reduce signs of aging on the skin. It also helps in boosting collagen production in cells so that fine lines, wrinkles, age spots, and other marks on the skin are reduced over time.
After applying retinol cream, it penetrates deep into the dermis where sun damage has occurred due to overexposure to sunlight that triggers free radicals in skin cells. These radicals cause the destruction of collagen which leads to sagging of skin and wrinkles.
Vitamin A is known for its antioxidant properties which help remove harmful toxins from the body, reduce inflammation and prevent premature aging caused by environmental factors like exposure to the sun or smoking when taken orally.
Similarly, carotenoids in foods like carrots, sweet potatoes, dark leafy greens, and apricots are known to protect skin from damage caused by UV rays when eaten regularly. These antioxidants can also reduce inflammation which is advantageous for people with acne or psoriasis on the skin.
Vitamin A is essential for the production of sebum in skin cells that help moisturize it naturally so using sunscreen lotion with SPF 15 or higher before going outdoors is necessary even if you have an oily skin type.
It’s better to incorporate plenty of vitamin A-rich foods in your diet rather than taking supplements unless advised by dermatologist to do so for specific skin conditions.
Vitamin A supplements are available in the form of capsules, tablets or liquids. Retinol is also known as vitamin A and can be used in skin creams to help reduce wrinkles, fine lines, and other signs of aging on the skin.
Retinol-based Vitamin A creams are not advised for use during pregnancy or breastfeeding period but you can take tablets containing beta-carotene instead which is a type of Vitamin A that your body converts into retinol when needed.
Beta-carotene is an antioxidant that has similar properties to Retinol so it helps reverse sun damage like dryness and discoloration caused by overexposure to the sun. It can also boost collagen in cells to keep complexion glowing and reduce the appearance of acne scars and other marks on the skin.
Vitamin A supplements may not be suitable for people who take blood thinners like warfarin as it can affect Vitamin K levels in the body that’s essential for the clotting of blood after an injury. People with liver disease should also avoid taking retinol-based supplements as they increase the risk of drug toxicity due to the reduced metabolism process in the liver.
Overdose of Vitamin A from any source can cause side effects such as irritation, redness, and itchiness on facial skin while excessive intake from supplements or oral form can lead to nausea, fatigue, loss of appetite, and weight loss.
