Magnesium is an essential mineral involved in over 300 enzymatic reactions in the body. Its deficiency, very common in the Spanish population due to soil depletion and the modern diet, manifests as fatigue, muscle cramps, insomnia, anxiety, and irritability. Not all types of magnesium are the same: magnesium bisglycinate is the most bioavailable and best-tolerated form for digestion, while citrate and malate are also excellent options. In this collection, you'll find magnesium supplements in various forms and dosages, from trusted brands like Solgar, Solaray, and Physalis, so you can choose the one best suited to your needs.
