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.

The fizzy evening ritual has a devoted following: reviewers say the warm drink itself signals wind-down and keeps them regular. The raspberry-lemon flavour divides people and the laxative kick is real if you overscoop. Parents mention sharing smaller doses with teens.
