Why Magnesium Glycinate?
There are many forms of magnesium. Magnesium oxide (the cheapest) is poorly absorbed and causes diarrhea in many people. Magnesium glycinate is bound to glycine (an amino acid), which improves absorption and is gentle on the digestive system. It's the form most often recommended by integrative medicine doctors.
Sleep Benefits
Magnesium activates the parasympathetic nervous system (rest and digest) and regulates melatonin. Many people report significantly better sleep quality within a week of starting magnesium glycinate. Take it 30–60 minutes before bed for best results.
Muscle Cramps
Magnesium is essential for muscle relaxation — it's the counterpart to calcium, which causes muscle contraction. Deficiency is a common cause of nighttime leg cramps and muscle spasms. Many people find that magnesium supplementation eliminates cramps that have bothered them for years.
