You might believe that taking supplements is always good for your health — but when it comes to magnesium, there’s something important you should know.
The Rise of Supplement Trends
From magnesium to potassium, new supplement trends seem to pop up on social media every week. One week it’s all about boosting potassium, the next it’s “fibermaxxing.” While these trends may sound healthy, experts caution that not everyone should jump on them without understanding their personal health needs.
Magnesium, the fourth most abundant mineral in the body, is essential for many functions, including muscle and nerve activity, blood sugar control, and bone health. Many people are indeed deficient in magnesium, and some claim that taking supplements helps them sleep better or feel more relaxed. But that doesn’t mean it’s safe or necessary for everyone.
When Supplements Can Become Dangerous
Medical professionals have urged people to stop blindly following supplement trends they see online. In fact, if you fall into one of the following two categories, you should be particularly cautious before taking magnesium or any other supplement.
1. People With Kidney Problems
If you have kidney issues, magnesium supplements can be risky. According to WebMD, impaired kidneys struggle to filter excess magnesium from the body, which can lead to dangerous buildup — a condition known as magnesium toxicity.
High magnesium levels can cause severe side effects such as:
- Irregular heartbeat
- Low blood pressure
- Confusion
- Slow or shallow breathing
- Coma
- And in extreme cases, even death
Doctors strongly advise: Do not take magnesium if you have kidney problems.
