Pure Encapsulations Magnesium Glycinate 90 Capsules Fast verdict: This is a clean, easy-to-compare magnesium glycinate capsule with 120 mg elemental magnesium each. Its main weakness is value: the label is simpler than many competitors, but the premium price is not backed by a public product-specific lab report in the reviewed sources. Best for: people who value a minimal formula and flexible one-capsule dose math Skip if: you want the lowest cost per 100 mg or a public batch certificate Serving: 1 capsule; suggested use 1 to 4 capsules daily Active formula: 120 mg magnesium as magnesium glycinate per capsule Quality signal: certified gluten-free, non-GMO, and hypoallergenic brand claims Value position: about $0.30 per capsule and $0.25 per 100 mg Who this product may fit People who want to see the elemental amount per capsule without dividing a multi-capsule serving. Shoppers who prefer a short other-ingredients list. People who value flexible capsule math more than bargain pricing. Readers who already know magnesium glycinate fits their broader decision. If the form choice is not settled, use the magnesium form selector before paying a premium for a label that may not match the real goal. Who should skip it Budget-first shoppers comparing cost per 100 mg of elemental magnesium. People who require a named sport certification or an inspectable batch COA. Anyone who expects a premium brand to guarantee a sleep or anxiety outcome. People with kidney disease or medication-spacing concerns who have not checked safety fit. A clean label does not remove magnesium's dose, GI, kidney, or medicine-spacing considerations. Review magnesium interactions when those issues apply. Label facts snapshot The label is unusually easy to compare because one capsule is one serving and provides 120 mg of elemental magnesium. The brand allows one to four capsules daily, but that flexibility also means daily cost can range widely. Per capsule Elemental magnesium 120 mg No four-capsule division is needed to understand the amount. Suggested use Routine range 1 to 4 daily Daily cost and total supplemental intake depend on the chosen routine. Bottle Count 90 capsules A 90-day supply at one daily or 22.5 days at four daily. Formula style Other ingredients Short list Vegetarian capsule and ascorbyl palmitate are the main listed extras. Proof status for this review This is a label-based editorial review. We checked the public label, serving size, active amount, current retailer or brand information, named quality signals, ingredient evidence, and recurring public review themes. It is not a hands-on test, lab certificate, or medical recommendation. We did not find a public batch COA or original in-hand evidence for this bottle. Brand-level manufacturing reputation should not be converted into an unstated product-specific test result. What is in the formula? Each vegetarian capsule supplies 120 mg of magnesium as magnesium glycinate. The suggested use is one to four capsules daily with food, which makes the label flexible but also changes the value and total-dose picture. The listed other ingredients are a vegetarian capsule and ascorbyl palmitate. The product is presented as certified gluten-free, non-GMO, and hypoallergenic. Magnesium glycinate is often chosen for tolerance, but user comfort and clinical usefulness still vary. The form name does not prove a sleep, anxiety, or migraine result for this exact bottle. Low routine One capsule daily 120 mg About 29% of the Daily Value and the lowest daily cost path. High label routine Four capsules daily 480 mg A high supplemental amount that needs total-intake and tolerance context. Formula Main distinction Minimal capsule This product sells simplicity more than a novel delivery system. Decision Main tradeoff Clarity vs premium price The label is easy to read; the value case is less automatic. Strengths, tradeoffs, and red flags What looks strong Excellent label clarity: 120 mg per capsule makes dose and cost math simple. Minimal excipients: the other-ingredients list is short. Flexible routine: the label offers a range rather than forcing a four-capsule serving. Dietary screening: gluten-free, non-GMO, and hypoallergenic claims are stated. What may change the decision Premium cost: the price per 100 mg is higher than several mainstream alternatives. Wide suggested-use range: one to four capsules can create very different dose and cost outcomes. Public proof gap: no batch-specific certificate was available in the reviewed source set. Red flags before you buy Do not assume a premium brand makes 480 mg daily appropriate for everyone. Do not treat public migraine, sleep, or anxiety testimonials as product-specific efficacy evidence. Check total magnesium from other products before using the high end of the label range. Price and value analysis At $27 for 90 capsules, one capsule costs about $0.30 and each 100 mg of elemental magnesium costs about $0.25. One capsule daily is a manageable premium; four daily raises the routine to about $1.20 per day. Per capsule Unit cost About $0.30 A clear number because each capsule is a serving. Per 100 mg Magnesium cost About $0.25 Higher than value-first multi-capsule options. At four daily Maximum label cost About $1.20/day The flexible label can become an expensive routine. Use the price per effective dose calculator when package size, serving burden, or active amount makes two products look more similar than they are. Is there third-party testing or quality proof? The public listing identifies certified gluten-free, non-GMO, and hypoallergenic positioning. Those are useful product-fit details, not substitutes for a posted potency or contaminant report. Without an inspectable batch COA or named independent certification in the source set, the quality score should reward label clarity while remaining conservative about verification. Use-case fit, evidence limits, and safety NIH describes magnesium as an essential nutrient and notes that supplement forms and absorption differ. The evidence belongs to magnesium and particular clinical contexts, not automatically to a premium bottle. A one-capsule serving stays below the supplemental magnesium upper limit, but the top of the label range provides 480 mg. Higher supplemental amounts are more likely to create GI effects and deserve a reasoned plan. Safety boundary Magnesium may cause diarrhea, nausea, or cramping even when a form is marketed as gentle. Kidney disease increases the importance of professional dose guidance. Separate magnesium from certain antibiotics and bisphosphonates according to professional instructions. Use lab and symptom context rather than escalating toward four capsules because the label permits it. If medicines, pregnancy, surgery, kidney or liver disease, abnormal labs, or multiple supplements are part of the picture, use the supplement interaction checklist and involve a qualified clinician or pharmacist. Alternatives to compare Compare this product against both a value-first glycinate and a lower-capsule mainstream option. Solaray Magnesium Glycinate Lower cost per 100 mg, but a four-capsule serving and added BioPerine. Nature Made Magnesium Glycinate A mainstream two-capsule option with 200 mg per serving. NOW Magnesium Glycinate Tablets A value-oriented tablet format with different swallowing and serving tradeoffs. FAQ How much magnesium is in each Pure Encapsulations capsule? Each capsule provides 120 mg of elemental magnesium as magnesium glycinate. How long does the 90-capsule bottle last? It lasts 90 days at one capsule daily, 45 days at two daily, or 22.5 days at four daily. Is the premium price justified? The strongest reasons to pay more are clear per-capsule dose math and a minimal formula. The reviewed sources did not provide public batch-level proof that makes the value decision automatic. Can this product be used for sleep? Some users report sleep benefits, but ingredient and testimonial evidence does not prove that this exact product treats insomnia.
