Magnesium supplementation improves sleep quality by modulating neurotransmitter activity and nervous system relaxation.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
