Unbuffered Magnesium Glycinate 1000mg | Xandro Lab | 90 Capsules | 100% Chelated Supports Sleep Muscle Recovery Nerve

WHAT IS MAGNESIUM?Magnesium is an essential mineral your body uses every day but can't make on its own. It's a cofactor in over 300 bodily processes, from producing energy and maintaining a steady heartbeat to helping muscles relax and supporting the nervous system as it winds down for sleep. An estimated 2.4 billion people worldwide don't get enough magnesium from food alone (Passarelli et al., The Lancet Global Health, 2024), making it one of the most common nutritional gaps globally.This is why magnesium is one of the most commonly supplemented minerals worldwide.Supports restful sleepRelieves muscle tiredness and supports recoverySupports relaxation, nerve, and heart functionContributes to bone healthWHY WE UPGRADEDNot all magnesium glycinate is the same. Many “buffered” formulas combine magnesium glycinate with magnesium oxide, allowing them to display a higher elemental-magnesium number on the label.Magnesium oxide contains a high proportion of elemental magnesium, but it has low solubility and is generally less bioavailable than more soluble forms of magnesium. This means a larger number on the label doesn’t necessarily mean more magnesium is available for your body to use.Our formula provides 140 mg of elemental magnesium entirely from unbuffered magnesium glycinate (aka magnesium bisglycinate*), with no magnesium oxide added. It is designed for good solubility, absorption and digestive tolerance."Glycinate" vs. "bisglycinate", what’s the difference? They are the same molecule. Magnesium binds two glycine molecules, and "bis" just means two.Buffered vs. unbuffered magnesium glycinateSame magnesium on the label. The difference is how much of it you use. BufferedUnbufferedWhat's in itMagnesium glycinate mixed with magnesium oxide100% magnesium glycinate (aka magnesium biglycinate), nothing addedThe number on the labelLooks higher – oxide inflates it, but doesn’t reflect what’s absorbedLooks lower and reflects what’s actually in the capsule – but all of it is chelated, so better absorbedWhat your body absorbsLess – the oxide portion is barely taken up (~4%)More – chelated magnesium uses amino acid pathways in your gutOn your stomachCan loosen stools (oxide acts as a laxative)Gentle, non-laxativePriceUsually cheaperUsually costs moreWHY IT COSTS MOREYou can buy magnesium glycinate for half this price. The difference is what you’re paying for.The less expensive bottle typically means a buffered formulation, fewer quality controls, or both. This product costs more because of how it’s made:Fully unbuffered – no magnesium oxide subsidising the doseManufactured in a GMP-certified, HACCP facility in SingaporeIndependently third-party tested for purity, microbial safety, heavy metals, and disintegrationNo fillers, no artificial colors, no preservativesA superior formulation that’s an investment in compounding your Biocap.HIGHLIGHTSIn each 2-capsule serving:1000 mg of 100% magnesium glycinate – unbuffered, no magnesium oxide140 mg of elemental magnesium per serving (33% of the Daily Value), designed to complement the magnesium you get from foodSupports restful sleep, muscle recovery, and healthy nerve and heart functionZero fillers: no rice powder, no buffering agents, no artificial colors or preservativesGluten-free, dairy-free, non-GMO, suitable for vegans90 vegetarian capsules – a 45-day supplyQuality: Manufactured in a GMP-certified, HACCP facility. Independently third-party tested for purity, microbial safety, and heavy metals. Made in Singapore.Building your Biocap starts with the fundamentals your body runs on every day. Magnesium is one of them – it’s a cofactor in over 300 bodily processes, from energy production to nerve signaling. Getting a form your body can actually use is part of that daily investment.WHO IT’S FORFor better sleepTake 30 to 60 minutes before bed. Magnesium supports the nervous system processes involved in winding down and staying asleep.For muscle recoveryTake after training or activity. Magnesium plays a role in muscle relaxation and recovery after exertion.For everyday nervous system supportMagnesium is a cofactor in nerve signaling and helps maintain a healthy stress response.Caution: If you’re pregnant or nursing, have a medical condition, or take prescription medication, consult a healthcare professional before use.SCIENTIFIC EVIDENCEAn estimated 2.4 billion people worldwide, roughly 31% of the global population, do not get enough magnesium from diet alone (Passarelli et al., The Lancet Global Health, 2024).In a clinical trial of adults with insomnia, magnesium supplementation led to improvements in sleep time, sleep efficiency, and insomnia severity scores compared to placebo (Abbasi et al., 2012).In a study of nearly 4,000 adults, higher magnesium intake was associated with better sleep quality and a lower likelihood of short sleep duration (Zhang et al., 2022).In a double-blind study, magnesium supplementation significantly reduced muscle soreness at 24, 36, and 48 hours after intense exercise, compared to placebo (Reno et al., 2022).A randomized controlled trial in healthy elderly women found that 12 weeks of magnesium supplementation significantly improved physical performance measures, including chair-stand time and walking speed (Veronese et al., 2014).In a randomised, double-blind trial, 250 mg of elemental magnesium bisglycinate taken 30 to 60 minutes before bed showed a modest but statistically significant improvement in insomnia severity scores over 4 weeks (Schuster et al., 2025).In a 2-year trial, magnesium supplementation led to a significant increase in bone density in 71% of treated postmenopausal women (Stendig-Lindberg et al., 1993).A large cohort study found that low serum magnesium levels were associated with increased fracture risk over long-term follow-up (Kunutsor et al., 2017).In a preclinical study, mice given the same elemental dose of magnesium from different compounds did not absorb it equally. Glycinate raised brain magnesium levels where another form did not, and reached the bloodstream at every dose tested, while some forms required higher doses to do so (Ates et al., 2019). Animal data – not yet confirmed in humans.PRODUCT DETAILSServing size: 2 capsulesServings per container: 45Elemental magnesium per serving: 140mg (33% DV)From: 1000mg Magnesium Glycinate (unbuffered)Other ingredients: Hypromellose (vegetarian capsule)Does not contain: Magnesium oxide, buffering agents, flavoring, artificial colors, preservatives, or additivesHOW TO USETake 2 capsules daily, after food, preferably in the evening.
