Country Life's **magnesium bisglycinate** delivers a full 400mg dose for sleep and muscle relaxation — right at the top of the clinically studied supplemental range, and in the form your body absorbs most easily. The bisglycinate form is also gentle on your stomach, so you can take the full dose without the digestive upset that some magnesium forms cause.
Worth knowing: a serving is three tablets, and 400mg of elemental magnesium sits just above the 350mg upper limit set for supplemental magnesium. That limit exists because magnesium can loosen stools at higher intakes — but bisglycinate is the form least likely to do that. For sleep, take all three tablets with your evening meal to reach the studied dose.
