Magnesium One - 120 x Magnesium Glycinate 500mg Capsules

Magnesium is involved in over 600 enzymatic reactions in your body — from energy production and protein synthesis to nervous system regulation and muscle function. Yet studies consistently show that the majority of adults do not get enough from diet alone. The result is a silent deficiency that shows up as poor sleep, muscle tension, elevated stress, and impaired recovery.

Not all magnesium is created equal. Most cheap supplements use magnesium oxide, which has notoriously poor bioavailability — as low as 4%. Magnesium One uses magnesium glycinate, the form chelated with the amino acid glycine. This delivers significantly higher absorption rates and virtually eliminates the digestive discomfort common with other forms.

Glycine itself has calming properties, which is why magnesium glycinate is particularly effective for sleep quality and nervous system support. Clinical research in the Journal of Research in Medical Sciences has shown magnesium supplementation improves sleep onset, duration, and efficiency in adults with low baseline levels.

Every capsule is pharmaceutical-grade, independently tested, and free from gluten, dairy, soy, and artificial additives. Take one to two capsules in the evening, 30 to 60 minutes before bed, for best results.

• Supports deeper, more restorative sleep by activating the parasympathetic nervous system and regulating GABA receptors — enhanced by the naturally calming properties of the chelated glycine
• Addresses the widespread magnesium deficiency that affects the majority of adults — a silent shortfall linked to poor sleep, muscle cramps, elevated stress, and impaired recovery
• Uses magnesium glycinate, the most bioavailable and gut-friendly form available — significantly better absorbed than magnesium oxide, citrate, or carbonate with virtually zero digestive discomfort
• Supports over 600 enzymatic reactions in your body including energy production, protein synthesis, blood pressure regulation, and nervous system function
• Promotes faster muscle recovery and reduced tension after exercise by supporting proper muscle contraction and relaxation at the cellular level
• Helps regulate the stress response by modulating cortisol and supporting healthy HPA axis function — making it one of the most effective natural tools for daily stress management
• Pharmaceutical-grade magnesium glycinate, independently third-party tested for purity exceeding 99%, and free from gluten, dairy, soy, and artificial additives

Take 1 capsule daily with a meal. Consistent daily use is important for sustained results. Do not exceed the recommended dose.

Why is Magnesium so important?

Magnesium is involved in over 600 reactions in your body — from energy production to DNA repair. Despite this, an estimated 50–80% of adults in Western countries are deficient, and standard blood tests miss most cases because only 1% of the body's magnesium is in the blood.

Why Magnesium Glycinate?

Not all forms of magnesium are equal. The glycinate form achieves significantly higher absorption than common forms like magnesium oxide, and the glycine component provides additional benefits — it helps lower core body temperature to signal your body it's time for sleep.

What does the research say?

A double-blind, placebo-controlled trial showed magnesium supplementation significantly improved time to fall asleep, sleep duration, and sleep quality in older adults with insomnia. Abbasi et al., Journal of Research in Medical Sciences, 2012 ↗

Magnesium deficiency amplifies the body's stress response by increasing cortisol output. Supplementation helps bring these pathways back into balance, supporting both recovery and sleep quality.

Why Magnesium One?

We chose glycinate specifically for its superior absorption, gentle digestion, and the added sleep-supporting benefits of the glycine bond. Each batch is independently tested for purity and heavy metal content.
