Vitamins are essential substances that participate in all vital processes in the body. They support the immune system, metabolism, the functioning of internal organs, and the health of skin, hair, and nails. Although vitamins are needed in relatively small quantities, their deficiency or excess can significantly affect human health.<\/p>\n

Why are vitamins important for the body?<\/strong><\/h2>\n

Each vitamin performs unique functions, ensuring the normal functioning of different body systems. Some of them help regulate energy metabolism, others promote cell growth, support the nervous system or strengthen the immune system.<\/p>\n

The body is unable to synthesize most vitamins on its own, so they must be obtained from food or in the form of dietary supplements.<\/p>\n

Main groups of vitamins and their functions<\/strong><\/h2>\n

Vitamins are divided into water-soluble<\/strong> and fat-soluble<\/strong>.<\/p>\n

Water-soluble vitamins<\/strong><\/h3>\n

These vitamins do not accumulate in the body and are excreted in the urine, so they need to be regularly replenished through nutrition.<\/p>\n

Fat-soluble vitamins<\/strong><\/h3>\n

These vitamins can accumulate in the body, so their deficiency develops more slowly than water-soluble vitamins.<\/p>\n
