Magnesium glycinate — also known as magnesium bisglycinate — is magnesium bonded (chelated) to two molecules of the amino acid glycine. The chelated structure improves absorption and makes it gentler on digestion than other magnesium forms.
As per EFSA-authorised health claims, magnesium contributes to:
- Muscle, nerve, and psychological function
- Energy-yielding metabolism and electrolyte balance
- Reduction of tiredness and fatigue
- Maintenance of bones and teeth
- Protein synthesis and cell division
- 100% Pure Magnesium Glycinate — No fillers, flow agents, or unnecessary additives
- Fully-Chelated & Non-Buffered — High-absorption magnesium glycinate, free from magnesium oxide
- Third-Party Lab Tested — Independently verified purity and potency you can trust
- Made in the UK — Produced to ISO 9001, HACCP and GMP-certified standards

WHY CHOOSE MAGSUPPS
At MAGSUPPS we specialise in magnesium — and nothing else. Here’s what makes our magnesium glycinate different.
Most magnesium glycinate supplements aren’t pure magnesium glycinate. Many brands use a buffered ingredient — a blend of magnesium glycinate and magnesium oxide — without disclosing it.
Magnesium oxide is cheaper, poorly absorbed, and more likely to cause the digestive issues magnesium glycinate is specifically praised for avoiding. Most don’t list it on the ingredients panel.
Customers believe they’re buying pure magnesium glycinate when they’re not. Ours is different.
MAGSUPPS Magnesium Glycinate is fully-chelated and non-buffered — free from magnesium oxide, fillers, flow agents, and unnecessary additives. Just two ingredients. Magnesium glycinate and a vegan capsule shell. Nothing else.
THIRD-PARTY LAB TESTED
From local UK manufacturing to independent third-party testing — every batch verified for purity and potency, with the Certificate of Analysis published publicly on our website.
Certificate of Analysis — Batch TC002, tested by Mission Mountain Laboratories (ISO/IEC 17025 accredited). Verifying magnesium content, heavy metals, and microbial safety.
REAL CUSTOMERS, REAL RESULTS
Trusted by thousands of customers across the UK — here’s what they’re saying.
“This is the best magnesium glycinate I have tried. It’s clean, no bulking agents and really does work. My pain levels have reduced and I am most definitely sleeping a lot better.” – Amazon Customer
“Great product! I noticed better sleep and increased performance in the gym. This is one of the few magnesium products that is pure and not buffered with the cheap magnesium oxide form.” – Vik
“Amazing pure product, very relaxing!” – Tess
“My sleep is actually better throughout the night and much deeper sleep, as also reflected in my sleep tracker, plus I don’t seem to have as many stressful dreams. So I am definitely going to continue with these as I believe they build up in your system. I recommend these are worth a try.” – Mr K
“If you’re looking for help with sleep, I can safely say this works. I was researching so many magnesium glycinate manufacturers and all seemed to fill their products with oxides or other nastys. This is pure. What I will say, is that I have 2 capsules before bed and my dreams have never been so vivid!” – Sam

FREQUENTLY ASKED QUESTIONS
Your top questions about magnesium glycinate — answered.
Magnesium glycinate — also known as magnesium bisglycinate — is magnesium bonded (chelated) to two molecules of the amino acid glycine. This chelated structure improves how the body absorbs magnesium, and makes it gentler on digestion than other magnesium forms.
As per EFSA-authorised health claims, magnesium contributes to:
- Muscle, nerve, and psychological function
- Energy-yielding metabolism and electrolyte balance
- Reduction of tiredness and fatigue
- Maintenance of bones and teeth
- Protein synthesis and cell division
Magnesium glycinate’s combination of high absorption and gentle digestion is what makes it one of the most well-tolerated forms of magnesium available — and a popular choice for everyday use.
Magnesium glycinate combines two compounds independently linked to sleep and relaxation — magnesium and glycine.
Magnesium contributes to normal psychological function and helps calm the nervous system. Glycine is an amino acid well-researched for its calming properties — studies suggest it can reduce the time it takes to fall asleep and improve overall sleep quality.
Together they make magnesium glycinate one of the most popular forms for those looking to support restful sleep.
Daily magnesium requirements vary by age and gender. In the UK, the recommended daily intake for adults is 300mg for men and 270mg for women.
Each MAGSUPPS Magnesium Glycinate capsule delivers 100mg of elemental magnesium (from 750mg of pure magnesium glycinate) — take 1 to 3 capsules daily depending on your needs. If you are unsure about the right dose for your individual needs, consult a healthcare professional.
Magnesium glycinate can be taken at any time of day. Most people prefer to take it in the evening — the calming properties of both magnesium and glycine make it well suited to a night-time routine. Taking it with food can also help absorption and reduce any chance of digestive discomfort.
Most people notice a difference within one to two weeks of consistent daily use — some sooner. Magnesium builds up in the body over time, so results are cumulative rather than immediate. Consistency matters more than timing.
Buffered magnesium glycinate is blended with magnesium oxide — a cheaper, far less absorbable form — to inflate the elemental magnesium number on the label. Most brands don’t disclose it. Non-buffered means pure magnesium glycinate with no magnesium oxide added. That’s what MAGSUPPS delivers.
Magnesium glycinate is one of the gentlest forms of magnesium available and is unlikely to cause digestive side effects at recommended doses. Unlike magnesium oxide, it is well tolerated even at higher doses. Taking significantly more than the recommended daily intake may cause loose stools in some individuals.
Yes. MAGSUPPS Magnesium Glycinate is suitable for both vegetarians and vegans. The magnesium glycinate ingredient is plant-derived and the capsule shell is made from hydroxypropyl methylcellulose (HPMC) — a vegan-friendly alternative to gelatine. Our products are not tested on animals.
