Finally back in stock after enormously popular demand - be sure to get yours before it's too late!
  • FOR CALM, RELAXATION & SLEEP - Feel the unique benefits of 100% Magnesium Glycinate, our twice-bound formulation (Bisglycinate) leverages the amino acid Glycine, known as an effective neurotransmitter in the brain which further boosts the calming effect of Magnesium tablets. Also suitable for restless leg syndrome relief, leg cramps at night and as Magnesium for sleep.
  • BIOAVAILABLE & GENTLE ON THE STOMACH - Our fully buffered chelated Magnesium is perfect for individuals who are sensitive to Magnesium Citrate or Oxide. The naturally calming Glycine molecule is inherently resistant to stomach acid - we bond the molecule twice (Magnesium Bisglycinate), to further enhance the transport to the gut, resulting in unrivalled absorption and results, while negating the requirement for absorption partners like Vitamin B6 or Zinc.
  • HOW TO TAKE FOR BEST RESULTS - Due to high bioavailability, less Elemental Magnesium is required per serving to see similar benefits to Magnesium Oxide based formulations. We therefore recommend taking two (2) capsules per day for the first month. If required, increase to three (3) capsules per day from month 2 onwards.
  • LABORATORY TESTED & CARBON OFFSET - All Oxford Origins products are carbon offset with the help of partner projects around the globe. Additionally, this Magnesium supplement is Vegan, non-GMO, free from dairy, soy, gluten, artificial colours and flavours. This Magnesium Complex is regulated for microbiology, PAH, pesticides, heavy metals and proudly conforms to, and exceeds EU regulations (EC) No: 1881/2006, 396/2005, 1169/2011.

Magnesium Glycinate Capsules FAQ

Why Choose Our Magnesium Glycinate?

Magnesium stands out as a crucial mineral, offering support for sleep, nervous system health, and muscle function. It's noteworthy that low magnesium levels are surprisingly common in the UK.

Magnesium cannot be taken in isolation, leading to the availability of various supplement forms. Magnesium glycinate, with its high bioavailability, ensures easy absorption by the body, providing an efficacy edge over less expensive magnesium forms.

An additional advantage of magnesium glycinate is the dual-action support that glycine provides. As an amino acid known for its calming effect on the brain, glycine positively influences sleep patterns through the body's circadian rhythm.

Moreover, magnesium glycinate is better tolerated than other magnesium forms, preventing digestive discomfort and potential upset stomach.

How Does Magnesium Contribute to Normal Sleep?

Magnesium, often referred to as the 'relaxation mineral,' plays a pivotal role in the production of GABA in the body—a neurotransmitter with a calming effect on the nervous system, essential for winding down the brain in preparation for sleep.

Restless nights, often caused by stress and racing thoughts, are managed by the body's stress response system, the HPA axis. Magnesium contributes to regulating the HPA axis.

Is Insufficient Magnesium Intake Common?

Despite being the fourth most abundant mineral in the body, data from the most recent National Diet and Nutrition Survey reveals that many individuals in the UK have insufficient magnesium intake. Contributing factors may include poor diet, pregnancy, illness, or medications. A daily intake of a high-quality magnesium supplement proves instrumental in maintaining optimal magnesium levels.

How Does Magnesium Support Muscle Recovery?

Magnesium collaborates closely with calcium, essential nutrients regulating muscle contractions. Calcium induces muscle contraction, while magnesium aids in muscle relaxation. Inadequate magnesium levels relative to calcium may lead to excessive muscle contraction, causing cramps and spasms. Incorporating magnesium helps strike a balance, supporting effective muscle recovery and preventing discomfort.
