  • About Magnesium Glycinate Capsules

    Magnesium Glycinate Capsules deliver this essential mineral in a highly bioavailable chelated form, where magnesium is bound to the amino acid glycine for superior absorption. This gentle formulation supports muscle relaxation, promotes healthy sleep quality, and helps maintain optimal magnesium levels without the digestive discomfort often associated with other magnesium forms.

    Our Magnesium Glycinate Story

    We spotted a fundamental problem in the magnesium supplement market: despite magnesium being involved in over 300 enzyme systems and being crucial for countless biological processes, most people weren't getting the benefits they needed. Traditional magnesium supplements suffered from poor absorption rates and often caused uncomfortable digestive side effects, leaving users frustrated and magnesium-deficient.

    The solution was to focus on the chelated form of magnesium glycinate, where the mineral is chemically bound to glycine. This molecular structure allows the magnesium to bypass the typical absorption barriers in the digestive tract, delivering superior bioavailability while remaining gentle on the stomach. We carefully source our magnesium glycinate and subject every batch to rigorous third-party testing to ensure you receive a product that actually works the way magnesium supplementation should.

    Benefits

    • Supports Sleep: Promotes muscle relaxation and nerve function, helping users experience improved sleep quality and reduced muscle tension when taken regularly.
    • Improves Cognition: Supports various aspects of brain health including memory, focus, and information processing speed through magnesium's role in neurotransmitter function.
    • Supports Stress Levels: Helps regulate the body's stress response and promotes calm and relaxation, with studies suggesting it helps reduce anxiety symptoms and improve resilience to stressful situations.
    • Supports Mood: Contributes to emotional balance through magnesium's neuroprotective properties and its involvement in neurotransmitter systems that influence mood regulation.

    Magnesium glycinate also supports long-term wellness by contributing to heart health through blood pressure regulation and healthy heart rhythm maintenance, while also playing a crucial role in bone health by supporting bone mineral density and calcium absorption.

    Mechanism of Action

    • Enhanced Bioavailability: The glycine component acts as a carrier for magnesium, allowing absorption as an intact dipeptide in the proximal small intestine through specialized dipeptide transport pathways.
    • pH Buffering Action: Glycine serves as an excellent pH buffer, significantly reducing the pH increase at tight junctions that typically hinders magnesium absorption in the digestive tract.
    • Enzymatic Cofactor Function: Once absorbed, magnesium acts as a cofactor in over 300 enzyme systems, regulating diverse biochemical reactions including protein synthesis, muscle and nerve function, and energy production.
    • Neurotransmitter Support: The glycine portion functions as an inhibitory neurotransmitter, contributing to the calming effects often experienced with magnesium glycinate supplementation.
    • Cellular Energy Production: Magnesium participates directly in both oxidative phosphorylation and glycolysis pathways, supporting efficient cellular energy metabolism throughout the body.

    Overview of the Science

    Research on magnesium glycinate has shown promising results across various areas of health and wellness. Studies suggest that this highly bioavailable form of magnesium may offer benefits for sleep quality, stress management, and cognitive function. Several clinical trials have demonstrated that magnesium supplementation can improve sleep parameters, including sleep efficiency and onset latency [1]. This is particularly notable in older adults and individuals with sleep disturbances. The mechanism appears to be related to magnesium's role in regulating neurotransmitters and melatonin production.

    In terms of stress management, magnesium glycinate has been shown to help regulate stress hormones and support the body's stress response. Some studies have found that magnesium supplementation may reduce anxiety symptoms and improve resilience to stressful situations. Cognitive function is another area where magnesium glycinate shows potential. Research indicates that it may support various aspects of brain health, including memory, attention, and information processing speed. This could be due to magnesium's involvement in neurotransmitter function and its neuroprotective properties.

    While magnesium glycinate shows promise on its own, some studies suggest that combining it with other supplements may offer synergistic benefits. For instance, pairing it with Bacopa Monnieri might enhance cognitive performance, while combining it with L-Theanine could provide additional support for stress management and relaxation.

    Ingredients

    Magnesium Bisglycinate Chelate Monohydrate:

    • 1,600mg per serving (2 capsules)
    • Provides 200mg elemental magnesium
    • 50% Daily Value

    The bisglycinate chelate form offers superior bioavailability compared to common magnesium compounds like oxide or citrate. In this chelated form, magnesium is bound to two glycine amino acids, creating a stable structure that protects the mineral from interference by other nutrients during absorption. This chelation process results in gentler digestion and more efficient uptake, making it an ideal choice for those who experience digestive discomfort with other magnesium forms.
