From the Guidelines
Magnesium glycinate is generally considered superior to magnesium succinate due to its higher bioavailability and gentler effect on the digestive system. When comparing the two, it's essential to consider the benefits and harms of each form of magnesium supplementation. While the provided study 1 focuses on magnesium oxide (MgO) rather than magnesium succinate or glycinate, it highlights the importance of magnesium supplementation in improving bowel movements and quality of life.
- Key differences between magnesium succinate and glycinate include their absorption rates and potential effects on the body.
- Magnesium glycinate is bound to the amino acid glycine, which may enhance absorption and have calming effects on the nervous system.
- Magnesium succinate, on the other hand, binds magnesium to succinic acid, which plays a role in energy production through the Krebs cycle.
- Typical dosing for magnesium glycinate is 200-400mg of elemental magnesium daily, often taken in divided doses.
- Both forms are less likely to cause digestive upset compared to magnesium oxide or citrate, as seen in the study 1, which reported little to no difference in diarrhea leading to treatment dose change or discontinuation between MgO and placebo.
- When choosing between magnesium succinate and glycinate, consider that magnesium glycinate has more research supporting its use for anxiety, sleep, and muscle relaxation, while magnesium succinate might theoretically offer additional metabolic support, although more research is needed to confirm this.
From the Research
Comparison of Magnesium Succinate and Magnesium Glycinate
- Magnesium succinate and magnesium glycinate are two different forms of magnesium supplements, each with its own unique characteristics and potential benefits.
- According to a study on the absorption profile of different magnesium compounds 2, magnesium glycinate was found to be one of the amino acid-bounded compounds that showed increased tissue magnesium levels.
- However, there is no direct comparison between magnesium succinate and magnesium glycinate in the provided studies.
- The study 2 did investigate the effects of different organic magnesium compounds, including magnesium citrate and magnesium malate, on tissue magnesium levels, but magnesium succinate was not included in the study.
- Another study 3 discussed the role of magnesium in cardiovascular disease, but did not specifically compare different forms of magnesium supplements.
- Studies 4, 5, and 6 focused on the role of magnesium in kidney function and disease, but did not provide a direct comparison between magnesium succinate and magnesium glycinate.
Bioavailability and Absorption
- The study 2 found that the absorption of organic magnesium compounds, such as magnesium glycinate, was better than that of inorganic compounds.
- However, the study did not investigate the bioavailability and absorption of magnesium succinate specifically.
- The effects of split dosages of high doses of magnesium compounds on tissue magnesium levels were also investigated in the study 2, but the results did not provide a clear comparison between different forms of magnesium supplements.
