Not intended to diagnose, treat, cure or prevent any disease. Food supplements should not replace a varied, balanced diet and healthy lifestyle. ⚠️ Consult your GP before taking this supplement if you have kidney (renal) impairment, are pregnant or breastfeeding, or are taking antibiotics (quinolones, tetracyclines) or bisphosphonates. Do not exceed 400mg elemental magnesium daily from supplements without clinical supervision. What Is Magnesium Bisglycinate? Magnesium Bisglycinate is a chelated form of magnesium in which one magnesium ion is bonded to two molecules of glycine — a naturally calming amino acid. The chemical name is magnesium diglycinate (CAS 14783-68-7, molecular formula C₄H₈MgN₂O₄). The chelation process creates a stable mineral-amino acid complex that is absorbed more efficiently than inorganic magnesium forms such as oxide or carbonate, and is significantly gentler on the digestive system. Each capsule delivers 650mg of magnesium bisglycinate, providing approximately 91mg of elemental magnesium — around 14% of the bisglycinate compound weight by molecular ratio. This is higher elemental magnesium per capsule than many lower-strength magnesium glycinate products on the UK market. You can buy Magnesium Bisglycinate 650mg Capsules directly from Charge Products at chargeproducts.co.uk or on eBay with same-day UK dispatch. Magnesium is an essential mineral involved in over 300 enzymatic reactions in the human body. It plays a central role in energy metabolism, protein synthesis, muscle and nerve function, electrolyte balance, and the maintenance of normal bones and teeth. UK population studies consistently show widespread suboptimal magnesium intake — making supplementation relevant for a broad range of adults. Our Magnesium Bisglycinate 650mg Capsules are encapsulated in-house at our own UK facility, which holds a 5 Star Food Hygiene Rating awarded by Southend-on-Sea City Council. Zero fillers. Zero binders. Zero flow agents. Vegan HPMC capsule shell. Food supplement — not a medicine. COMMONLY ASKED Is Magnesium Bisglycinate the Same as Magnesium Glycinate? Yes — they are chemically identical. Magnesium bisglycinate and magnesium glycinate both describe one magnesium ion bonded to two glycine molecules (CAS 14783-68-7, formula C₄H₈MgN₂O₄). The prefix "bis" simply means two — it is the more technically precise chemical name. "Glycinate" is the consumer shorthand used on most supplement labels. There is no functional, bioavailability or efficacy difference between products labelled bisglycinate and those labelled glycinate when both are fully chelated. = Same Compound = Same Bioavailability ≠ Name Only difference Authorised EU/UK Health Claims for Magnesium Magnesium has 9 authorised EU/UK health claims — one of the most comprehensive claim sets of any food supplement ingredient. These claims are established and require no further qualification: ⚡ Energy Metabolism Magnesium contributes to normal energy-yielding metabolism 😴 Tiredness & Fatigue Magnesium contributes to reduction of tiredness and fatigue 💪 Muscle Function Magnesium contributes to normal muscle function 🧠 Nervous System Magnesium contributes to normal functioning of the nervous system 🧘 Psychological Function Magnesium contributes to normal psychological function 💧 Electrolyte Balance Magnesium contributes to electrolyte balance 🦴 Bones & Teeth Magnesium contributes to maintenance of normal bones and teeth 🧬 Protein Synthesis Magnesium contributes to normal protein synthesis 🔬 Cell Division Magnesium has a role in the process of cell division Authorised under retained EU Regulation 1924/2006 (GB NHC Register). Claims apply at a minimum of 56mg elemental magnesium per daily serving. Each 650mg capsule provides approximately 91mg elemental magnesium. Magnesium Bisglycinate vs Other Magnesium Forms Form Bioavailability Digestion Best For Bisglycinate / Glycinate ✅ High — chelated form, gut-protected Excellent — no laxative effect Sleep, calm, muscle, daily use Citrate Good Loose stools at higher doses Constipation, occasional use Malate Good Generally well tolerated Energy, muscle soreness L-Threonate Good — crosses blood-brain barrier Well tolerated Cognitive support Oxide Low (as low as 4%) Laxative — draws water into bowel Not recommended for daily supplementation Bioavailability comparison: Coudray et al. (2005, Magnesium Research) — tested ten magnesium compounds and found organic chelated forms significantly outperformed inorganic forms including oxide. PubMed 16548135 The Glycine Advantage — Why Bisglycinate Is Different 😴 Glycine's Independent Sleep Role Glycine is an inhibitory neurotransmitter in the brainstem and spinal cord. Japanese RCT data (Bannai et al., 2012 — PubMed 22293292) showed 3g glycine before bed reduced sleep onset time, improved sleep quality and reduced next-day fatigue. When you take magnesium bisglycinate, you receive both magnesium and a meaningful glycine dose in one capsule. 🧘 Stress & Cortisol Regulation Magnesium acts as a co-factor in cortisol regulation and supports adrenal function. Low magnesium is associated with heightened stress reactivity and elevated cortisol. A 2026 dietary analysis found that individuals with low magnesium intake reported significantly higher subjective stress levels. Bisglycinate's superior absorption makes it particularly relevant for addressing this. 💪 Muscle Function & Recovery Magnesium regulates calcium channels in muscle cells, preventing excessive muscle contractions that cause cramping. It has an authorised EU/UK claim for normal muscle function. Bisglycinate's superior absorption means more elemental magnesium reaches muscle tissue compared to poorly absorbed forms like oxide. 🧬 Digestive Tolerance Unlike magnesium citrate or oxide, bisglycinate does not draw water into the bowel. It is absorbed in the small intestine via amino acid transporters, bypassing the osmotic mechanism that causes the laxative effect of other forms. This makes it suitable for long-term daily supplementation and for those with sensitive digestion.

Wholesale Available — contact chargeproducts.co.uk/pages/contact How to Take Magnesium Bisglycinate 650mg Capsules 1 Take 1–2 capsules dailyStart with 1 capsule and increase to 2 if needed. Most people take 1 capsule in the morning and 1 in the evening, or 2 capsules together in the evening for sleep and relaxation support. 2 Take with foodTaking with a small amount of food improves absorption and further reduces any chance of digestive sensitivity, though bisglycinate is already one of the most stomach-friendly forms available. 3 Evening preferred for sleep supportTaking magnesium bisglycinate 30–60 minutes before bed is preferred by those specifically seeking sleep and relaxation support — the glycine component supports calm and reduces motor neuron excitability. 4 Be consistent — allow 2–8 weeksMost people notice improvement in sleep quality and muscle tension within 1–2 weeks. Broader effects on mood and stress resilience take 4–8 weeks. Do not exceed 400mg elemental magnesium daily from supplements without GP guidance. 160K+ Verified Sales ⭐ 5 FSA Rating 650mg Per Capsule 9 Authorised Claims 2016 UK Est.

Yes — they are chemically identical. Both names describe one magnesium ion bonded to two glycine molecules (CAS 14783-68-7). "Bisglycinate" is the technically precise name; "glycinate" is the common consumer shorthand. There is no functional or bioavailability difference. How much elemental magnesium is in each 650mg capsule? Each 650mg capsule provides approximately 91mg elemental magnesium — about 24% of the daily 375mg NRV. This is based on magnesium comprising approximately 14% of the molecular weight of the bisglycinate compound. What are the authorised UK health claims for magnesium? Magnesium has 9 authorised EU/UK health claims: normal energy-yielding metabolism · reduction of tiredness and fatigue · normal muscle function · normal functioning of the nervous system · normal psychological function · electrolyte balance · maintenance of normal bones and teeth · normal protein synthesis · has a role in cell division. When is the best time to take magnesium bisglycinate? Evening, approximately 30–60 minutes before bed, is preferred for sleep support — the glycine component promotes relaxation. Taking with food improves absorption. Daily consistency matters more than the specific time of day. Is magnesium bisglycinate gentle on the stomach? Yes — bisglycinate is one of the most stomach-friendly forms of magnesium. Unlike citrate or oxide, the chelated form is absorbed via amino acid transporters without drawing water into the bowel. No laxative effect at standard doses. How does magnesium bisglycinate compare to magnesium oxide? Magnesium oxide has very low bioavailability — as low as 4% in some studies — and commonly causes digestive discomfort. Magnesium bisglycinate is chelated and significantly more bioavailable, with no laxative effect. Chelated forms consistently outperform oxide in bioavailability research. How long does magnesium bisglycinate take to work? Most people notice improvements in sleep quality and muscle tension within 1–2 weeks. Broader mood, energy and stress effects develop over 4–8 weeks of consistent daily use. Can I take magnesium bisglycinate with Vitamin D? Yes — Vitamin D3 and magnesium work synergistically. Magnesium is required for the activation of Vitamin D in the body, and Vitamin D supports magnesium absorption and utilisation. They pair well together. Space magnesium from calcium by around 2 hours if taking both. Is this product suitable for vegans? Yes. The capsule shell is vegan HPMC.
