What is it and what is it used for? El Naturalista Hair & Nails, in a 48-capsule presentation, is a food supplement specifically designed to help maintain healthy hair. It also helps revitalize brittle and brittle nails. It contains a formula that combines sulfur-containing amino acids such as taurine, cystine and methionine with essential minerals such as iron and zinc. In addition, it provides folic acid and B vitamins to create a blend that promotes the recovery and maintenance of these parts of the body. Its high concentration of L-methionine and L-cysteine ​​plays a key role in the synthesis of keratin. This helical protein contains high levels of sulfur, an element present in both nails and hair. On the other hand, zinc is an inhibitor of 5-alpha-reductase, which is why it is recognized as an essential mineral in the process of keratin synthesis. Iron, in turn, is considered a key nutrient in nutrition. When iron levels are insufficient in the body, it can trigger hair loss, and the hair can become dry and brittle. Finally, soy lecithin is a component rich in inositol that promotes hair health. In addition to all this, B vitamins play a direct role in keratin metabolism. They also promote the proper functioning of other minerals. These vitamins are closely linked to the growth, strength and thickness of nails. In addition, folic acid is important for cell renewal in various tissues in the body, including hair. Who is it for?
