Muscles+ by ESC Laboratoire is a care product that combines the energizing benefits of spirulina with vitamins, trace elements and amino acids recognized for their muscle support properties and in particular: Vitamin E: Vitamin E is an essential nutrient that promotes muscle development by supporting connective tissue that ensures skin and muscle elasticity. It also contributes to the body's resistance to training by supporting blood oxygenation and the proper functioning of the cardiovascular system. Selenium: selenium plays a major anti-oxidant role in athletes, in close connection with Vitamin E. Selenium conditions the activity of anti-oxidant enzymes and participates in the regeneration of vitamin E. A selenium deficiency can lead to greater fatigue during exercise, impaired recovery and muscle pain. Lysine: Lysine is an essential amino acid, which means that the body cannot produce it and must be obtained from food. It is present in significant quantities in muscles and has numerous biological functions. It contributes, among other things, to the development of the horse's muscles and the repair of muscle micro-lesions after exercise, the growth of bones, the formation of collagen and antibodies, as well as the metabolism of carbohydrates.
