Vitamin A - key to eye, skin, and immune health
Vitamin A is an essential nutrient that plays a key role in the body. Learn everything about its functions, health benefits, sources, as well as the risks associated with deficiency and overdose.
The role of vitamin A in the body
Vitamin A is important for eye, skin, and mucous membrane health, as well as supporting the immune system. As an antioxidant, it helps protect cells from damage caused by free radicals. Vitamin A is also important for proper growth and development.
Health benefits of vitamin A
Vitamin A affects eye health by improving vision quality, especially at night. It also supports the immune system, helping fight infections. With the ability to strengthen skin barriers, vitamin A contributes to skin and hair health and can also help combat signs of aging.
Recommended daily intake of vitamin A
Daily vitamin A requirements depend on age, gender, and health status. Generally, adult men need about 900 mcg and women need about 700 mcg of vitamin A per day. However, it is important to note that pregnancy and breastfeeding increase the need for vitamin A.
Sources of vitamin A
Vitamin A is found in both animal and plant products. Good sources of vitamin A include liver, eggs, oily fish, carrots, sweet potatoes, broccoli, and spinach. Vitamin A supplementation may be considered in case of deficiency, but should be done under the guidance of a doctor.
What are the symptoms and effects of vitamin A deficiency?
Vitamin A deficiency can lead to vision disturbances, dry skin, mucous membranes, and weakened immune system. At risk groups for deficiency include children, pregnant women, people with fat absorption disorders, and vegetarians.
Vitamin A overdose
Vitamin A overdose can cause headaches, nausea, vomiting, dry skin, and loss of appetite. In extreme cases, it can lead to liver and bone damage. To avoid overdose, follow the recommended dose of vitamin A supplementation and consume it in moderate amounts from foods.
Vitamin A in cosmetics
Vitamin A cosmetics, such as retinol creams, can contribute to skin regeneration, reducing wrinkles and fighting acne. However, the use of vitamin A cosmetics may cause irritation, so it is important to test them on a small area of skin before using and follow the manufacturer's recommendations.
Summary
Vitamin A plays a key role in maintaining eye, skin, and immune health. To ensure proper body function, it is important to consume an adequate amount of vitamin A from a variety of sources. Vitamin A deficiency and overdose can lead to serious health problems, so it is important to monitor its intake carefully.
