What is vitamin A deficiency and how much vitamin A do you need every day?

Vitamin A is a fat -soluble vitamin that plays a crucial role in vision, immune function, growth and development of the body. A Vitamin A deficiency occurs if the body does not absorb or save enough vitamin A to cover daily needs.

The recommended daily supply of vitamin A varies depending on age and gender. According to the German Nutrition Society (DGE), adults need between 0.8 and 1.1 milligrams of retinol activity equivalent (RAE) per day. Pregnant and breastfeeding women have a higher need of 1.1 to 1.5 milligrams of Rae a day.

The symptoms of a vitamin A deficiency often develop gradually and can initially be unspecific. The most common signs include:

  • Malabsorption: Diseases of gastrointestinal tract such as celiac disease, Crohn's disease or chronic pancreatitis can affect vitamin A.
  • Liver diseases: Since vitamin A is stored in the liver, liver diseases such as cirrhosis or hepatitis can lead to a deficiency.
  • Interactions with medication: Certain drugs such as cholestyramine or orlistat can hinder the absorption of fat -soluble vitamins.
  • Genetic factors: Rare genetic disorders such as the vitamin A transporter defect lead to an increased need or reduced storage.

Frequently asked questions

How is a vitamin A deficiency?

Frequent symptoms of vitamin A deficiency are night blindness, dry eyes, dry and scaly skin, increased susceptibility to infect, delayed growth in children and dryness. In severe cases, a vitamin A deficiency can even lead to blindness.

Where is there a lot of vitamin A?

You can find a lot of vitamin A in animal foods such as liver, egg yolk, butter and high -fat fish species such as salmon or mackerel. Provitamin A is also contained in vegetable foods such as carrots, kale, spinach, paprika and apricots in the form of beta-carotene that can convert your body into vitamin A.

What does vitamin A do on the face?

Vitamin A is a real beauty booster for your face! It stimulates collagen production, which ensures tighter and younger -looking skin. In addition, vitamin A promotes cell renewal, which makes your complexion more even and more radiant. Vitamin can also help with acne: it regulates sebum production and thus counteracts impurities and inflammation. Your complexion becomes clearer and pure.

What blocks vitamin A recording?

What happens if you take too much vitamin A?

A too high supply of vitamin A over a longer period of time can lead to hypervitaminosis A. Symptoms of vitamin A overdose are headache, nausea, vomiting, blurred seeing, coordination disorders and skin changes. In the case of pregnant women, there is also an increased risk of malformations in the unborn child.

What is the difference between vitamin A and retinol?

The main difference between vitamin A and retinol is that vitamin A is a generic term for a whole group of fat -soluble vitamins, while retinol is a special form of vitamin A. Retinol is the purest and most active form of the vitamin that can be used directly by the body. You can absorb vitamin A through animal foods and vegetable carotenoids, whereas retinol mainly occurs in animal sources such as liver, egg yolk and dairy products. In cosmetics, retinol is often used as an anti-aging active ingredient because it stimulates collagen production and renews the skin.

Is beta-carotene the same as vitamin A?

No, beta-carotene is not the same as vitamin A, but it is a preliminary stage of it. Beta-carotene belongs to the group of carotenoids that the body can convert into vitamin A. However, this conversion process is limited, so that you take less vitamin A from beta-carotene than from animal sources with pre-shaped retinol. While vitamin A is mainly responsible for vision, immune system and cell growth, beta-carotene as antioxidant has further positive effects. It protects your cells from harmful free radicals and strengthens your skin from the inside against UV radiation.
