When taken in very large amounts (greater than 350 mg daily), magnesium is POSSIBLY UNSAFE. Large doses might cause too much magnesium to build up in the body, causing serious side effects including an irregular heartbeat, low blood pressure, confusion, slowed breathing, coma, and death.
The benefits of magnesium supplementation in healthy individuals aren't clear, but Dr. Nassar says that taking a magnesium supplement every day likely isn't unsafe for most people. Just be sure you're not taking too much magnesium. The maximum dietary allowance for most adults is around 400 mg or less.

Early signs of excessive magnesium intake can include low blood pressure, facial flushing, depression, urine retention, and fatigue. Eventually, if untreated, these symptoms can worsen and include muscle weakness, difficulty breathing, irregular heartbeat, and even, in very rare cases, cardiac arrest.

Can you take vitamin D and magnesium together? Yes. In fact, it's probably best to take both together. Because so many people have low magnesium levels, vitamin D supplements on their own aren't very helpful for a large portion of the population.
When taken in very large amounts (greater than 350 mg daily), magnesium is POSSIBLY UNSAFE. Large doses might cause too much magnesium to build up in the body, causing serious side effects including an irregular heartbeat, low blood pressure, confusion, slowed breathing, coma, and death.
Highly absorbable, magnesium glycinate is recommended for anyone with a known magnesium deficiency and less likely to cause laxative effects than some other magnesium supplements.
Worsening of Underlying Conditions: If you have an underlying health condition that is managed with magnesium supplementation, stopping it suddenly can worsen the symptoms or lead to a flare-up of the condition.
