WHAT IS VITAMIN A?

Vitamin A is a fat-soluble vitamin that plays an important role in maintaining human health. It is found in a variety of foods, including animal and plant foods. Vitamin A exists in many forms, including retinol, retinyl esters, and β-carotene.

SOURCE

Vitamin A:

Animal foods:

Liver: Animal liver is a good source of vitamin A, especially beef liver and chicken liver. Liver is rich in retinol and retinyl esters.

Egg yolk: Egg yolk also contains a certain amount of vitamin A, mainly in the form of retinol esters.

Cod liver oil: Cod liver oil is a good source of vitamin A and vitamin D, especially cod liver oil from sharks, whales and deep-sea fish.

Plant foods:

Carrots: Carrots are rich in beta-carotene, a plant-derived provitamin A. In the body, beta-carotene can be converted into active retinol.

Spinach: Spinach is a green leafy vegetable rich in beta-carotene and other carotenoids, and is one of the good sources of vitamin A.

Pumpkin: Pumpkin is rich in beta-carotene and is a nutritious source of vitamin A.

Sweet peppers: Red, yellow and orange bell peppers contain high amounts of beta-carotene and are a good source of plant-based vitamin A.

EFFECT

Maintain visual health: Vitamin A is one of the components of the visual pigment in the retina and is essential for maintaining visual health and normal visual function. It helps maintain the normal structure of the retina and is involved in the activity of photoreceptors during visual conduction.

Promote growth and development: Vitamin A plays an important role in cell differentiation, growth and development. During infancy and childhood, vitamin A is necessary for maintaining normal growth and development. Vitamin A deficiency may lead to problems such as growth retardation and skeletal deformities.

Maintain skin and mucous membrane health: Vitamin A helps maintain the normal structure and function of the skin and mucous membranes. It promotes the renewal and repair of epidermal cells, helping to prevent problems such as dry skin, roughness, ulcers and infections.

Support the immune system: Vitamin A is also very important for the normal functioning of the immune system. It helps to enhance the body's resistance to infection, promotes the proliferation and activity of immune cells, and helps reduce the occurrence of infections and diseases.

Maintain reproductive health: Vitamin A is also important for the health of the reproductive system in men and women. It is involved in regulating the development and function of germ cells, helping to maintain normal reproductive hormone levels and the normal function of the reproductive system.

SIDE EFFECT

Acute poisoning: Long-term intake of large amounts of vitamin A may lead to acute poisoning, manifested by symptoms such as headache, dizziness, nausea, vomiting and fatigue.

Skin problems: High doses of vitamin A may cause dry, flaky, itchy skin or even abnormal skin pigmentation.

Bone problems: Excessive vitamin A may affect bone health, leading to bone hyperplasia or reduced bone density, increasing the risk of fractures.

Liver damage: Long-term high intake of vitamin A may cause damage to the liver, manifesting as abnormal liver function or liver damage.

Nervous system problems: In extreme cases, vitamin A poisoning may cause neurological problems such as dizziness, insomnia, feelings of lethargy, and mood swings.

Bleeding problems: Excessive amounts of vitamin A may interfere with the blood clotting process, increasing the risk of bleeding.

Affects bone development: Long-term excessive intake of vitamin A by pregnant women may affect the bone development of the fetus and even increase the risk of birth defects.

Vision problems: Although vitamin A is essential for visual health, excessive intake may affect vision, causing symptoms of blurring or blindness.

STORAGE

Moisture-proof: Vitamin A should be stored away from humid environments, as moisture may cause the product to deteriorate or mold.

Light-proof: Vitamin A should be stored in light-proof containers or packaging to avoid direct sunlight.

High-temperature protection: Vitamin A is best stored at room temperature or slightly below room temperature, avoiding excessive temperatures, as high temperatures may accelerate its degradation.

Avoid oxygen contact: Try to keep the packaging or container of vitamin A sealed to reduce the oxidative effects of oxygen on it.
