Too much magnesium can cause muscle cramps and spasms.

Infact verdict: Mixed (48/100).

The claim that too much magnesium can cause muscle cramps and spasms is not strongly supported by the evidence. The sources indicate that magnesium generally acts as a muscle relaxant and is used to prevent cramps and spasms. Excessive magnesium intake is more commonly associated with muscle weakness rather than cramps. The evidence suggests that an imbalance between calcium and magnesium, rather than excess magnesium alone, may lead to muscle issues. Therefore, the claim is misleading as it oversimplifies the relationship between magnesium and muscle function.
