Magnesium Glycinate

Magnesium is an essential mineral that supports numerous areas of health, including the nervous system, muscle function, and sleep. Despite its importance, low levels of magnesium are surprisingly common in the UK.

Magnesium supplements come in various forms, with Magnesium Glycinate standing out due to its high bioavailability. This means it is easily absorbed by the body, making it more effective than cheaper forms of magnesium. Additionally, Magnesium Glycinate is well-tolerated and less likely to cause digestive discomfort compared to other forms of magnesium.

One of the unique benefits of Magnesium Glycinate is the dual action of glycine, an amino acid known for its calming effect on the brain. Glycine can positively influence sleep by regulating the body's circadian rhythm, enhancing the overall benefits of the supplement.

Our Magnesium Glycinate supplement is crafted in the UK without additives, providing a high-quality option to support your health naturally.

Take 2 capsules per day during or after a main meal. For best results, take 1 capsule with breakfast and 1 capsule with lunch.

For maximum benefit, take for at least 90 days. Magnesium is a water-soluble mineral and will begin to work quickly, but to fully replenish depleted magnesium levels can take up to 4 months.

Store in a cool, dry place.

  • Reduces Anxiety and Depression: The calming effects of magnesium and glycine together may lower symptoms related to stress and anxiety. (1)
  • Improves Sleep Quality: Enhances sleep by promoting muscle relaxation and supporting biochemical pathways associated with sleep, leading to improved focus and reduced daytime fatigue. (2)
  • Supports Blood Pressure: Works with calcium to maintain proper blood pressure levels and prevent hypertension, beneficial for cardiovascular health. (3)
  • Decreases PMS Symptoms: Shown to alleviate cramps and pain associated with PMS, likely due to its anti-inflammatory and muscle-relaxing properties. (4)

Magnesium Glycinate's efficacy in alleviating anxiety is attributed to its multifaceted biochemical influence on the nervous system.

It modulates neurotransmitter systems, reducing the release of excitatory neurotransmitters, acting as an antagonist at the NMDA receptor, and increasing GABA receptor agonist properties.

Magnesium influences serotoninergic pathways, enhancing serotonin receptor transmission, crucial for mood regulation. It interacts with the HPA axis, reducing ACTH release and modulating stress hormone sensitivity, thereby attenuating stress responses.

Furthermore, magnesium mitigates oxidative stress and stabilizes cellular and mitochondrial functions, supporting its role in long-term mental health benefits by improving sleep quality and lowering stress levels​​ (5).

Magnesium glycinate is often considered one of the most bioavailable forms of magnesium.

This means it's more easily absorbed by your body compared to other cheaper forms of magnesium, such as oxide.

The glycine in magnesium glycinate helps increase the absorption of magnesium across the intestinal wall, making it an effective choice for those looking to improve magnesium levels. (5)
