What Is Magnesium Glycinate and How Does It Work?

Magnesium glycinate (also magnesium bisglycinate) is a chelated form of magnesium, which binds the elemental magnesium with the amino acid, glycine (NIH, 2023). This combination improves the absorption of the intestine and reduces the laxative effect of other preparations such as oxide or citrate.

Magnesium is involved in more than 300 enzymatic processes, which affect nerve impulses, muscle formation, sugar regulation in the body, and muscle contraction (Mayo Clinic, 2023). Combined with glycine, which is the naturally relaxing neurotransmitter of the body, the outcome is a very easily absorbable mineral that promotes relaxation and sleep as well.

Why Your Body Needs Magnesium

Magnesium glycinate is a supplement that replenishes such stores without causing any side effects to the digestive system. According to the National Institutes of Health about half of adults fail to meet the daily magnesium requirements. It can cause fatigue, cramps, anxiety, and irregular heartbeat due to deficiency (NIH, 2023).

Low levels may stem from:

• Diets coupled with lack of leafy greens and nuts which are processed foods.
• Excess caffeine or alcohol
• Stress and poor sleep
• Some drugs (diuretics, PPIs, antibiotics)

• Patients taking antibiotics (especially the tetracyclines or fluoroquinolones) – magnesium will inhibit the absorption of the drug when taken at the same time.
• Patients using blood-pressure or heart medication – magnesium can augment the effect of calcium blocking agents or diuretics.
• Individuals who experience chronic diarrhea or gastrointestinal disorders – the fluid imbalance likely to exist may aggravate with magnesium supplements.
• People whose heart beats slowly or who are in a severe heart block – the relaxing effect of magnesium on the muscles can further decrease the strength of the cardiac rhythm.
• Patients who are taking thyroid drugs – magnesium may affect absorption; take at least four hour intervals between doses.
• Osteoporosis patients taking bisphosphonate medications – do not take magnesium at the same time of day so that drug absorption becomes impaired.
• Children and teenagers – only under doctoral guidance should it be supplemented.
• Pregnant or breastfeeding women – should only be used with the recommendation of a doctor to maintain the appropriate dosage and safety.
