1. Vitamin A. It is a natural antioxidant. The main function of the substance is to protect against infections and viruses. Vitamin A (or retinol) fights bacteria. It is also useful for vision: thanks to retinol, tension, fatigue go away from the eyes, the picture becomes clearer.
2. B vitamins. They have a complex effect on the body as a whole. They are especially important for the immune, circulatory and nervous systems. These substances improve metabolism, affect mental activity, activate the brain, speed up metabolism. For example, vitamin B12 (cobalamin) is essential for the normal functioning of the nervous system. The lack of this substance is fraught with negative consequences - mental disorder, the development of multiple sclerosis. It is the B vitamins that give our body vigor, energize and improve the physical and mental state.
3. Vitamin D. Calciferol is a complex of nutrients necessary for the normal functioning of the cardiovascular, immune and endocrine systems. Vitamin D takes part in the work of the intestines and kidneys, contributes to the stable state of the muscular system. Diabetes, atherosclerosis, and cancers are what calciferol is against.
4. Vitamin E. The substance affects the cardiovascular and circulatory systems. Thanks to vitamin E, blood clotting improves and blood vessels expand. Tocopherol acts on the skin, rejuvenating and restoring them. Well, if you are planning to conceive a child, vitamin E is an essential element.
5. Macronutrients. They are important for the full functioning of the body. For example, potassium improves memory, brain function, stabilizes blood pressure, and strengthens the heart muscle. Potassium and phosphorus affect the functioning of the intestines, bone tissue, and kidneys. Phosphorus separately influences the teeth, strengthening them. Calcium and sulfur are needed for healthy hair, nails, and bones. Sulfur removes free radicals from the body and improves blood sugar levels.
6. Microelements. The record holders for the amount of chromium, selenium and cobalt are here. What is their task? Cobalt takes part in hematopoiesis, cell renewal, elimination of bad cholesterol, slows down the aging of the skin. Thanks to cobalt, proteins, fats and carbohydrates are synthesized faster, and the endocrine system works smoothly. Chromium breaks down harmful cholesterol, promotes the synthesis of useful cholesterol, which has a positive effect on the heart and blood vessels. Chromium is a trace element that maintains the integrity of DNA, that is, it has a positive effect on heredity. Multiple sclerosis, stroke, obesity, gastritis - for all these diseases, chromium is prescribed. The viruses of hepatitis, herpes and tuberculosis are resisted by selenium. It also slows down the onset of menopause in women.
7. Amino acids. They help vitamins and minerals to be better absorbed and to perform their strengthening, antiviral, restorative and other functions. Amino acids are essential for bones, nails, hair, ligaments, tendons, muscles. Thanks to these substances, heavy metals and radionuclides are removed from the body.
8. Fatty acid. They are necessary as a prophylactic agent against cancer of the stomach, intestines, mouth, breast, ovaries, as well as against Alzheimer's disease, senile dementia. Fatty acids are beneficial for the brain and heart. These substances improve mood, reduce fatigue, and promote the production of serotonin.
