Magnesium Chloride by ESC Laboratoire has muscle-relaxing properties and helps reduce muscle tension during periods of intense exercise. Magnesium chloride promotes relaxation in stressed horses. Magnesium is an essential mineral but is not produced by the body. It helps in the fixation of electrolytes (calcium and potassium). A magnesium deficiency increases the difficulty in recovering and in particular the risk of cramps and muscle pain appearing. What should you combine the magnesium chloride care product with? If there is a risk of muscle contracture after intense physical effort, magnesium chloride can be supplemented with a course of Hippo Crampes, a liquid complementary food enriched with Vitamin E and trace elements (selenium, iodine, zinc, cobalt). Hippo Crampes participates in cell regeneration and recovery during periods of intense effort.
