Magnesium supplement craze faces scientific scrutiny

Magnesium has become a high‑profile dietary supplement, promoted for better sleep, reduced stress, fewer cramps and more energy. While the mineral is essential for muscle and nerve function, scientific evidence for many of these claims in healthy people is limited. The European Union allows health claims that magnesium helps reduce fatigue and supports normal metabolism, but it does not endorse benefits such as universal energy boosts or sleep improvement.

Health experts warn that taking popular supplements—including magnesium, vitamins A, D, E, K, iron, creatine, collagen, omega‑3, melatonin and probiotics—without medical assessment can exceed established Upper Intake Levels. As Dr. Bertina Ferrández notes, "Casi todos los nutrientes tienen un límite superior de consumo seguro" and exceeding these limits raises the risk of adverse effects and can mask underlying health conditions. She also stresses the importance of checking interactions with medications, pregnancy, lactation, and renal or hepatic issues.

Overall, the trend reflects a broader pattern of supplement overuse driven by social‑media hype, emphasizing the need for balanced diets and professional guidance over reliance on pills.
