Magnesium is involved in many normal processes, including muscle and nerve function and energy metabolism. Its importance does not mean that taking extra magnesium reliably improves sleep or causes weight loss.
Start with food variety
Nuts, seeds, legumes, whole grains and leafy vegetables can contribute magnesium. Choose foods that fit your preferences and needs rather than trying to obtain every nutrient from one “superfood”.
A symptom is not a diagnosis
Poor sleep, fatigue or muscle symptoms can have several causes. A supplement should not replace an assessment when symptoms persist. Nor should magnesium be promoted as a way to lower cortisol, remove abdominal fat or resolve insulin resistance.
Supplements have limits and risks
Higher supplemental doses can cause side effects and interact with medicines. Kidney problems can change safety considerations. Discuss the product and dose with a healthcare professional when supplementation is being considered.
