Magnesium Glycinate by Shed Supplements

The verdict. If you buy one thing off this page, this is the strongest candidate. Magnesium is one of the few supplements where the evidence is broad, the deficiency is genuinely common, and the cost of being wrong is close to zero. Glycinate is the form to pick if the last magnesium you took sent you to the bathroom.

Who this is for

• You sleep lightly, or wake at three and can't settle.
• You train, sweat a lot, and eat a fairly ordinary diet.
• Magnesium citrate or oxide upset your stomach and you assumed magnesium wasn't for you.

Who should skip it

If you have reduced kidney function, magnesium is one to clear with a doctor first — the kidneys are what clear the excess. If you already eat a lot of leafy greens, nuts, and legumes, you may simply not need it. And if you want a stimulant effect, this is the opposite kind of product.

What's actually in it

Magnesium bound to glycine. The binding is the whole point: glycinate is well absorbed and gentle on the gut, where cheaper forms like oxide are poorly absorbed and citrate has a laxative effect. Check elemental magnesium per serving on the label — that's the number that matters, and it is often far lower than the headline figure on the front.

What the research actually looks at

Magnesium is involved in hundreds of enzymatic processes, and the research looks at supporting muscle function, nervous system function, and sleep quality. It's better-evidenced than most of this category — though "better-evidenced" still means modest, real effects rather than transformation, and the strongest results tend to come from people who were low to begin with.

How we'd use it

Evening, with food. Give it two weeks. If you're taking it for sleep, take it at the same time nightly rather than only on bad nights — this is a level-raiser, not a switch.

The honest trade-offs

• Glycinate costs more per milligram than oxide or citrate. You're paying for absorption and tolerance.
• Capsules are usually large, and hitting a full dose often means two or three.
• Magnesium can interact with some antibiotics and other medicines. Space it out, and check.

Bottom line

The most defensible purchase in the whole store. Correct form, sensible category, low risk. If you're building a routine from nothing, start here.
