what the evidence says

Citrate is one of the better-absorbed common magnesium forms, with its most reliable, best-evidenced effect being osmotic: it draws water into the bowel, which is why it doubles as a regularity aid and why higher doses loosen stools. The general magnesium evidence for sleep and stress applies, with the deficiency caveat throughout.
