Pure Encapsulations Pure Encapsulations - Magnesium Glycinate, 180 caps
Pure Encapsulations Magnesium Glycinate - A highly bioavailable form of magnesium that supports the metabolism of macronutrients and energy production. Magnesium is an essential bone matrix mineral that promotes healthy bone metabolism. Magnesium also plays essential roles in maintaining healthy muscle contractile function. As magnesium regulates calcium channels, it may have an important role in controlling cramping. Several clinical trials have found that magnesium supports muscle function during intense exercise and helps to lessen nighttime leg cramps.

Why people keep reordering it
- Highly absorbable forms
- Chelated forms your body takes up, instead of oxide that mostly passes through.
- Calm and recovery
- Supports muscle relaxation, sleep quality and everyday stress resilience.
- Gentle on digestion
- Formulated to skip the laxative effect of cheaper magnesium.
Best suited to: night cramps or legs that will not settle, loose stools from other magnesium supplements, tired of swallowing four or five capsules.
What the research supports
One capsule gives you 120 mg of magnesium, and at two to three a day the bottle lasts two to three months.
Studies use 300 to 400 mg a day.
- Muscle cramps (evidence: moderate, from randomized controlled trial, meta-analysis)
- Muscles need magnesium to release after they tighten, and a shortfall leaves them prone to cramping. Trials at 300 mg and up show fewer cramps, most clearly in people who started out low.
- Sleep (evidence: mixed, from )
- Magnesium helps quiet an overactive nervous system, which is why some people take it before bed. Trials on sleep are split, and it tends to work best in people who were low to begin with.
- Digestive tolerance (evidence: moderate, from randomized controlled trial, meta-analysis)
- Bisglycinate binds magnesium to an amino acid rather than a salt, so it moves through the gut gently. It consistently causes less loose stool than oxide or citrate at the same elemental dose.

Is it right for you
Worth it if
- Night cramps or legs that will not settle
- Three capsules reach 360 mg of elemental magnesium, and the glycine carried with it has its own calming action on the nervous system.
- Loose stools from other magnesium supplements
- Bisglycinate is an amino acid chelate rather than a salt, so it does not draw water into the intestine the way citrate and oxide do.
- Tired of swallowing four or five capsules
- 120 mg of elemental magnesium per capsule is at the high end for a bisglycinate, so a studied dose is two or three pills rather than a handful.
Look elsewhere if
- Wanting magnesium to move the bowels
- Magnesium citrate or oxide produces the osmotic effect that bisglycinate is specifically chosen to avoid, and costs less to do it.
- Already using an electrolyte or greens powder
- Add up the elemental magnesium first. Those powders often carry 100 to 200 mg already, and stacking mostly buys you loose stools.
- Someone who struggles with capsules
- Magnesium bisglycinate powder stirred into water delivers the same form without swallowing three capsules, though it takes more volume and does not taste like nothing.
What to expect
If you are running low, two or three capsules in the evening often shows up as easier sleep onset and fewer night cramps within a week. Magnesium status itself refills slowly, so judge muscle tension and sleep quality at three to four weeks of steady use rather than on day two.
How it compares
- Compared with magnesium citrate
- Bisglycinate is absorbed as a chelate and stays gentle at three capsules, where a matched elemental dose of citrate loosens most people up. The tradeoff: Citrate is cheaper per milligram of elemental magnesium and is the better buy if regularity is what you are actually after.
- Compared with a cheaper bisglycinate at 100 mg per capsule
- 120 mg per capsule means fewer pills for the same elemental dose, and there is nothing in the capsule beyond the magnesium, the vegetarian shell and a trace of ascorbyl palmitate. The tradeoff: You pay a brand premium per capsule for that, and the difference in pill count is one capsule at a full dose.
