Strong evidenceMagnesium
Multiple randomised trials associate adequate magnesium status with normal sleep onset and muscle function. We state function, not disease.
The evidence근거
We grade the evidence, and we grade it honestly.
Most supplement sites imply everything works equally. We put a grade on every ingredient — including the ones that are only traditional use — so you can decide with your eyes open.
