What is vitamin A?
Vitamin A is one of the essential vitamins needed for many biochemical processes in the body. It is basically a group of fat-soluble compounds, including retinol, retinal, and retinyl esters. Vitamin A is naturally present in many foods. Our body stores vitamin A in the liver. We need this vitamin to keep our immune, reproductive, and skin health and vision strong.
Vitamin A: Benefits & Uses
Here are a few vitamin A functions in the body.
- Protect eye health: Inadequate vitamin A can result in poor vision health and cause night blindness. Therefore, if you wish to preserve your eyesight, include vitamin A foods in your diet.
- Support immune health: Vitamin A is needed to maintain a strong body's natural defense system. It is also involved in the synthesis of white blood cells. Therefore, vitamin A deficiency can make us more susceptible to infections and diseases.
- Antioxidant: Vitamin A acts as a potent antioxidant and protect us from the damaging effects of free radicals and oxidative stress.
- Promote healthy skin: Vitamin A may help prevent acne. Studies suggest that people with vitamin A deficiency are prone to acne issues. Due to vitamin A benefits for skin, it is a popular ingredient in skin creams.
- Healthy bones: Vitamin A is essential for strong bones as it is involved in developing new bone cells. It also helps absorb calcium, which is a critical bone mineral.
- May reduce cancer risk: Researchers believe that diets rich in vitamin A reduce the risk of developing bladder, cervical, and lung cancer.
Vitamin A Types
Vitamin A exists in two forms.
- Retinol: Retinol vitamin A is mainly found in animal-based vitamin A rich foods, like whole egg, meat, liver, and dairy foods.
- Beta-carotene (Pro vitamin A): This form is primarily found in plant-based vitamin A food sources like oranges, bell peppers, pumpkin, green leafy vegetables, carrots, sweet potato, papaya, and mango.
When we consume vitamin A in the form of beta-carotene, it gets converted to retinol for absorption in the small intestine.
