Cysteine also helps detoxify and protect cells from free radicals. In addition, due to the sulfur content, L-cysteine has important antioxidant properties. In combination with glycine and glutamic acid, L-cysteine promotes the formation of one of the most powerful antioxidants in the human body – glutathione. Glutathione, among other functions, is responsible for preserving antioxidants, such as vitamins C and E in active form. This is very important to help protect the body from toxins. Advantages of L-cysteine: Cysteine is capable of performing several important functions in the human body due to its specific structure, including sulfur, contributing significantly to overall health and well-being. For various chronic diseases, for example cataracts or arthritis, a large positive result will result in the taking of this amino acid.

The body can also turn this multifunctional nutrient into taurine, which is important for conducting electrical nerve impulses, digestion, and also the cardiovascular system. *How to use. For problems with hair loss and prevention, I advise taking Cysteine + Methionine + Zinc + Selenium. All 4 together and separately from the intake of other supplements, so they are better absorbed and complement each other, that is, they act in synergy. Drink courses: Cysteine + Methionine together 2-3 months after 1-2 months break, Zinc – month after month, Selenium – a week after 2 weeks. This is an approximate course.
