> 15 grams ?? Sounds hard on the kidneys but its a citrate formulation. Okay, I stand corrected on that one.Well, that's what Citro-mag brand has in it (15 g/300 mL), and I'd assume others are similar. I can't remember if I used one or two bottles.
It doesn't tend to enter systemic circulation though, so I would downplay the effect on the kidneys. It's a hyperosmotic laxative. The magnesium ions draw water from the gut wall into the gut. Some electrolytes get drawn in, too, so they recommend you hydrate with e.g. gatorade to replace the fluids. The hyperosmotic effect is far quicker than the uptake effect. By far the bulk of the mag gets flushed out the anus, rather than via uptake/renal discharge. In fact, net mag balance can go negative, due to electrolyte losses into the gut.
