Magnesium Glycinate: A Superior Form of Magnesium for Optimal Health Benefits

April 16, 2023 | Supplements and Nutrition

Magnesium is an essential mineral that plays a crucial role in over 300 biochemical reactions within the human body. It is involved in various functions, including nerve transmission, muscle function, energy production, and bone health. With magnesium’s importance in maintaining overall well-being, it is essential to ensure adequate intake. Magnesium glycinate, a highly bioavailable form of magnesium, has become increasingly popular among health-conscious individuals seeking to optimize their magnesium intake. In this article, we will delve into the benefits and science behind magnesium glycinate, highlighting its superiority over other forms of magnesium.

The Science Behind Magnesium Glycinate

Magnesium glycinate, a chelated form of magnesium bound to the amino acid glycine, boasts several advantages over other magnesium forms, such as magnesium oxide, citrate, or chloride. The primary benefit lies in its bioavailability, which pertains to the percentage of a substance that can be absorbed and utilized for its intended purpose when introduced into the body.

Extensive research has demonstrated that magnesium glycinate’s bioavailability is superior, thanks to glycine’s presence. As an amino acid, glycine plays a crucial role in facilitating the transport of magnesium across the intestinal wall, ensuring efficient absorption into the bloodstream. Consequently, this enhanced absorption means that a larger proportion of magnesium is available for the body to utilize, leading to more significant health benefits.

Moreover, the glycine component of magnesium glycinate offers additional health advantages. Glycine is an inhibitory neurotransmitter that can contribute to improved sleep quality and reduced stress by calming the nervous system. When combined with magnesium’s natural muscle-relaxing properties, the two compounds can work synergistically to promote relaxation and better sleep quality.

Furthermore, the chelated nature of magnesium glycinate also contributes to its gentle effect on the gastrointestinal system. Some forms of magnesium, like magnesium oxide or citrate, can cause digestive discomfort or laxative effects due to their osmotic properties, which draw water into the intestines. Magnesium glycinate, on the other hand, is less likely to cause such side effects due to its enhanced absorption and reduced impact on the intestinal environment. This makes it an ideal choice for individuals with sensitive digestive systems or those who have experienced adverse effects from other magnesium supplements.

Benefits of Magnesium Glycinate

  1. Improved sleep quality: Magnesium plays a critical role in regulating the sleep-wake cycle by influencing the production of melatonin, a hormone responsible for sleep regulation. Magnesium glycinate, in particular, has been found to be effective in promoting relaxation and improving sleep quality due to the calming effects of glycine.
  2. Enhanced muscle function: Adequate magnesium levels are crucial for proper muscle function, as the mineral plays a role in muscle contraction and relaxation. Magnesium glycinate supplementation can help prevent muscle cramps, spasms, and weakness associated with magnesium deficiency.
  3. Reduced anxiety and stress: Magnesium glycinate has been shown to exert a calming effect on the nervous system, potentially reducing symptoms of anxiety and stress. This effect can be attributed to magnesium’s role in regulating neurotransmitters and the additional calming properties of glycine.
  4. Improved bone health: Magnesium is essential for maintaining bone health, as it plays a role in bone mineralization and calcium regulation. By ensuring adequate magnesium levels, magnesium glycinate supplementation can help support bone strength and density, reducing the risk of osteoporosis.
  5. Cardiovascular health: Magnesium is vital for maintaining proper heart function and blood pressure regulation. Magnesium glycinate supplementation has been linked to a reduced risk of hypertension, arrhythmias, and other cardiovascular issues.

FitNeuro: A Comprehensive Magnesium Supplement for Optimal Brain Health

FitNeuro is a cutting-edge magnesium supplement that combines the power of three highly absorbable forms of magnesium: Magtein® (magnesium l-threonate), Albion® di-magnesium malate, and TRAACS® magnesium lysinate glycinate chelate. This potent blend is designed to optimize brain health, cognitive function, and overall well-being, making FitNeuro a superior choice for individuals seeking to enhance their magnesium intake.

Magtein® (magnesium l-threonate) is a patented form of magnesium that has been specifically designed to cross the blood-brain barrier efficiently. This unique characteristic allows Magtein® to effectively increase magnesium concentrations in the brain, which can lead to improved cognitive function, memory, and learning. In fact, research has shown that Magtein® can support synaptic density and plasticity, which are essential for healthy brain function.

Albion® di-magnesium malate is another highly absorbable form of magnesium, which is bound to malic acid. This combination offers enhanced bioavailability and ensures that a higher proportion of magnesium is absorbed and utilized by the body. Moreover, malic acid is known to play a vital role in energy production within cells, making Albion® di-magnesium malate an excellent choice for those looking to support their overall energy levels and well-being.

Lastly, TRAACS® magnesium lysinate glycinate chelate is a form of magnesium that is bound to two essential amino acids: lysine and glycine. This chelated form offers superior bioavailability and absorption, similar to magnesium glycinate. Additionally, the presence of lysine and glycine provides added health benefits, such as supporting immune function, muscle repair, and collagen production.

FitNeuro’s unique combination of Magtein® (magnesium l-threonate), Albion® di-magnesium malate, and TRAACS® magnesium lysinate glycinate chelate offers a comprehensive approach to magnesium supplementation. By targeting brain health, energy production, and overall well-being, FitNeuro is an ideal choice for individuals seeking a powerful, effective, and easily absorbable magnesium supplement.

Potential Side Effects and Precautions

Magnesium glycinate is generally well-tolerated, with few side effects reported. However, excessive intake of magnesium supplements can lead to gastrointestinal issues such as diarrhea, bloating, and cramping. It is essential to follow the recommended dosage guidelines to avoid these side effects. Additionally, individuals with kidney problems should consult their healthcare provider before taking magnesium glycinate, as impaired kidney function can affect the body’s ability to excrete excess magnesium.

Tips for Choosing and Using Magnesium Glycinate

  1. Select a high-quality supplement: To ensure optimal benefits, choose a magnesium glycinate supplement from a reputable manufacturer that adheres to strict quality control standards.
  2. Follow the recommended dosage: The recommended daily intake of magnesium varies depending on age, sex, and life stage. Consult the product label or your healthcare provider for guidance on the appropriate dosage.
  3. Opt for a slow-release formula: Some magnesium glycinate supplements feature a slow-release formula, which can help maintain steady magnesium levels throughout the day and reduce the risk of gastrointestinal side effects.
  4. Combine with a healthy diet: Although supplementation can be beneficial, it is essential to maintain a balanced diet rich in magnesium-containing foods such as leafy greens, nuts, seeds, legumes, and whole grains.
  5. Monitor for potential interactions: Magnesium glycinate may interact with certain medications, including antibiotics, diuretics, and bisphosphonates. Consult your healthcare provider if you are taking any of these medications to avoid potential interactions.


Magnesium glycinate stands out as a superior form of magnesium due to its high bioavailability and numerous health benefits. By incorporating magnesium glycinate supplementation into your daily routine, you can support a wide range of physiological functions, including sleep regulation, muscle function, stress management, bone health, and cardiovascular health. Always choose a high-quality supplement, follow the recommended dosage, and consult with your healthcare provider before starting any new supplement regimen.
