Magnesium takes care of the balance of electrolytes, to which it belongs. This is the name given to the group of metallic elements that maintain the balance between water and salt in our body. However, their only weakness is that they are excreted through sweat, which means we lose magnesium during physical activity.
Increased needs for this metal are also observed in pregnant and breastfeeding women, women of reproductive age, the elderly, and people who sweat more.
