Vitamin A, or beta-carotene or retinol. It is a fat-soluble vitamin and which stores in the liver and adipose tissue. Its first role in the body is to support growth and expansion of bone tissue. Extremely important for the proper production of hormones, which is important for the proper course of pregnancy. Indispensable for the proper functioning of the organ of sight. Its deficiency causes blurred vision, particularly nocturnal. Vitamin A is also important for our skin. Thanks to it, the protective function of the epidermis is strengthened and the loss of water is reduced. It increases the production of collagen, which affects the firmness of the skin. Vitamin A deficiency can lead to your eyes drying out, impair immunity, and breakage of the hair and nails. In addition to poor diet and problems with absorption, alcohol and smoking are contributing to its deficiency. It also works well in the fight against acne, but only after consulting your doctor. Working at the computer (people who strain the eyesight) also often affects the increased demand for vitamin A.
