Vitamin A (retinol, retinal, retinoic acid)
Vitamin A is a strong antioxidant important for the skin and its elasticity, softness and structure, as well as vision, growth, bone and teeth formation, immunity and the functioning of the nervous system. It is necessary for the reproductive system of both males and females and is important for the development of the embryo during pregnancy.

Good to know
A vitamin A test is recommended when indications and symptoms appear that show its deficiency: night-blindness, dry eyes and hair, Bitot’s spots (pearly spots on the conjunctiva) as well as for those who suffer from thyroid and skin diseases, cataracts and inflammation of the ocular mucous membrane. More vitamin A is needed when engaging intensively in sports, during pregnancy and breastfeeding.
- scaly, dry skin
- dryness of the eyes
- breaking nails
- breakout of pimples
- sores in the mouth
- declining condition of the hair
- disordered vision
- slower growth for children
It has been shown that long-term and substantial vitamin A deficiency may cause the development of eye diseases, e.g., night-blindness, cornea inflammations.
Excess vitamin A in the body is associated with the use of nutritional supplements. The excess of this vitamin accumulates in the liver; a prolonged increase in its concentration can, therefore, even cause liver damage.
Symptoms characteristic to overdosing:
- headaches, bone and joint pains
- peeling skin
- foggy vision
- deteriorated vision definition
- Your test results will be ready within 1 working day.
