AI avatars and influencers promote high-dose magnesium supplements on social media, claiming benefits for anxiety, sleep, and weight management. However, doctors warn these trends often spread misinformation about health risks, particularly for those with kidney or heart issues. The standard recommended intake of magnesium is around 400mg per day, but some supplements contain up to 700mg, raising concerns about potential overdoses. Excessive magnesium can lead to severe side effects including diarrhea, nausea, and in extreme cases, cardiac arrest. Experts stress the importance of relying on natural food sources for magnesium rather than supplements and call for greater responsibility from social media platforms regarding health-related advertisements. The dietary supplement market is booming, with a predicted growth rate, further complicating the landscape of health misinformation. While magnesium serves vital health functions, especially in certain medical conditions, its broad promotion lacks sufficient scientific backing and can endanger public health.
