Vitamin A

Vitamin A is also one of the fat-soluble vitamins and belongs to the antioxidants. It affects your vision, gene regulation (cell growth/differentiation, reproduction and embryogenesis) and the development or maintenance of various tissue structures such as the (mucous) skin, bones and connective tissue. Your body produces vitamin A by converting it from your food. In diet, in plant sources we mostly find the inactive precursor (the beta-carotene) in yellow and green vegetables such as carrots, spinach, kale and fennel. In animal sources, it can be found as a storage form (retinyl ester), for example in liver, fish and eggs. Nicotine, alcohol and caffeine deplete your body of vitamin A.

Reasons for my level to change:

Reasons for a deficiency are e.g.: – insufficient intake with food, – reduced absorption capacity (e.g. in chronic intestinal diseases or acute gastrointestinal diseases), – increased need (e.g. during pregnancy), lower storage capacity (e.g. in alcohol dependence with associated liver damage)

When should I get tested?

If there is reasonable suspicion of a deficiency – in the best case, it will be determined by a doctor. However, vitamin A, C and biotin level determinations are rarely carried out, as they are usually consumed in sufficient form with a balanced diet. Yes, even with the occasional pizza or a pack of chips in between.
