Magnesium has an important neuromuscular function, acting simultaneously with calcium. Calcium is a stimulator of muscle contractions and Magnesium, by contrast, promotes muscle relaxation. As a brand that values scientific research, we know that magnesium is one of the most deficient nutrients in the Western diet. So often we no longer even recognize the signs of their deficiency: tiredness, irritability, cramps, and anxiety, are just some of the signs. Not to mention that bad night sleep, stress, exercise, among others, increase the body's needs in this mineral. With Magnesium you are provided with 570 mg of magnesium per day, enough to ensure your needs, even on the most intense and stressful days.
