Magnesium One - 120 x Magnesium Glycinate 500mg Capsules

Magnesium is involved in over 300 enzymatic reactions in your body — including the ones that govern sleep, muscle recovery, and the nervous system's ability to settle down at the end of the day. Most adults are running at the lower end of optimal levels, and the symptoms are easy to mistake for everyday stress.

Magnesium One delivers it in the form your body absorbs most reliably: glycinate.

Why most magnesium supplements miss

Magnesium comes in many forms. Magnesium oxide (the cheapest) has bioavailability around 4%. Magnesium citrate is moderate. Magnesium glycinate — magnesium bound to the amino acid glycine — is one of the most bioavailable forms, with bonus support for calm and sleep architecture from the glycine itself.

The form matters more than the milligram count on the label. A high-dose cheap magnesium that you don't absorb does less than a moderate-dose well-formulated one.

How magnesium supports healthy aging

Magnesium contributes to normal muscle function, nervous system function, and the energy-yielding reactions inside every cell. It supports the sleep architecture that lets your body actually recover overnight. It backs the calming side of biology that becomes harder to access naturally after 40.

What's in each capsule

500mg of magnesium glycinate per capsule, providing approximately 100mg of elemental magnesium. Two capsules daily delivers a meaningful daily intake. Hypromellose capsule, no proprietary blends, no synthetic additives.

Who it's for

Adults 40+ whose sleep, recovery, or muscle function isn't where they want it. Trainers and active adults supporting recovery. Anyone whose longevity routine has the daytime energy side covered and wants to support overnight restoration too.

How to take it

Two capsules in the evening, roughly an hour before bed. Magnesium glycinate is gentle on the stomach and works well taken with or without food. Daily use is where the effect compounds.

What to expect

Most people notice steadier evenings and easier sleep onset within the first one to two weeks. Muscle recovery improvements typically follow over weeks two to four. Magnesium glycinate is not a sedative — it supports your body's natural calming and recovery pathways.

• 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.
