Magnesium glycinate is highly bioavailable, easily absorbed by the body, and treats magnesium deficiency
Magnesium is an essential mineral that plays a crucial role in various physiological and biochemical functions in the body. It is involved in more than 600 enzymatic reactions and is necessary for maintaining optimal bone density, regulating serum glucose levels, controlling nerve firing, and causing muscle relaxation. However, many people do not consume enough magnesium in their diets, which can lead to a magnesium deficiency.
Magnesium glycinate is a form of magnesium that is highly bioavailable, meaning it is easily absorbed by the body. It is formed by combining magnesium with the amino acid glycine, creating a true chelate. This combination provides an absorption advantage over other forms of magnesium, such as magnesium oxide, which has limited bioavailability due to its poor solubility. The absorption of magnesium glycinate occurs primarily in the small intestine, with some absorption in the large intestine. It is absorbed as an ion within an hour of ingestion and reaches 80% absorption after 6 hours.
The high bioavailability of magnesium glycinate makes it an effective treatment for magnesium deficiency. It can be easily absorbed by the body, helping to correct low magnesium levels. This is particularly beneficial for individuals with conditions that affect magnesium absorption, such as diabetes or inflammatory bowel disease (IBD), or those whose magnesium levels are impacted by alcohol or medication use. By addressing magnesium deficiency, magnesium glycinate supplementation can provide additional benefits, including improved bone health, blood sugar management, reduced anxiety, and better sleep.
In addition to its absorption advantages, magnesium glycinate is generally well-tolerated and safe for most people. It is available in pill or powder form and can be purchased from supplement or health stores. However, it is always recommended to consult with a healthcare professional before starting any new supplement, especially if you are taking medications, to ensure there are no potential interactions or adverse effects.

Magnesium L-threonate is brain bioavailable, passes through the blood-brain barrier, and improves neuronal function
Magnesium L-threonate is a unique compound that is efficiently absorbed by the body due to the bonding of threonic acid (a sugar compound derived from vitamin C). It has been shown to pass through the blood-brain barrier more effectively than any other form of magnesium. This is due to its high bioavailability compared to other magnesium supplements, which don't cross the blood-brain barrier easily.
The blood-brain barrier (BBB) is formed by brain capillary endothelial cells, which separate the blood from the extracellular fluid in the neuropil. The BBB plays a pivotal role in the tight regulation and rigorous stabilization of the chemical composition of brain extracellular fluid, promoting normal neuronal signalling.
Magnesium L-threonate's ability to cross the blood-brain barrier means it can effectively deliver magnesium to brain cells, thereby increasing magnesium levels in the brain and neurons. This can lead to improved neuronal function and brain health, particularly in memory, learning, attention, and focus.
In a 2010 study, healthy Chinese adults who took a magnesium L-threonate-based supplement for 30 days recorded better scores on a clinical memory test than those who took a placebo. Another study found that supplementation with magnesium L-threonate in older American adults significantly improved overall cognitive scores compared to a placebo.

Magnesium glycinate is cost-effective and gentle on the digestive tract
Magnesium glycinate is a cost-effective and gentle option for those seeking to improve their sleep. It is a highly bioavailable supplement, which means it is easily absorbed by the body through the small intestine. This high rate of absorption makes it an ideal choice for individuals experiencing magnesium deficiencies or conditions that can lead to magnesium deficiencies, such as digestive disorders.
Magnesium glycinate is formed by combining magnesium with the amino acid glycine, which gives it calming properties. This combination helps promote relaxation and sleep by reducing stress and anxiety, which are common barriers to sleep. Research has shown that glycine may help relax the mind and body, making it easier to fall asleep and stay asleep. Its calming effects and high bioavailability make it a popular choice for those seeking a good night's rest.
In addition to its sleep-promoting benefits, magnesium glycinate can also provide other advantages. Its ability to influence blood sugar and heartburn regulation makes it a versatile supplement. It is also less likely to cause digestive discomfort, a common side effect of other magnesium forms. This gentleness on the digestive tract means you can take it close to bedtime without worrying about stomach disturbances.
Furthermore, magnesium glycinate is a more budget-friendly option compared to magnesium L-threonate. Its cost-effectiveness, combined with its calming and relaxing effects, makes it a popular choice for individuals seeking to improve their sleep quality and duration. However, it is always recommended to consult with a healthcare professional before starting any new supplement to ensure it aligns with your specific needs and health goals.

Magnesium L-threonate improves sleep quality, enhances memory, and boosts cognitive function
Magnesium L-threonate (MgT) is a supplement that can improve sleep quality, enhance memory, and boost cognitive function. MgT is unique in its ability to cross the blood-brain barrier, allowing it to enter the brain more efficiently and increase magnesium levels in the brain. This increased bioavailability of magnesium in the brain has been linked to improved sleep, enhanced cognitive function, and better memory retention.
Several studies have demonstrated the benefits of MgT in improving sleep quality. In one randomized controlled trial, 35-55-year-olds with self-reported sleep problems showed significant improvements in sleep quality and daytime functioning after taking MgT for 21 days. MgT improved deep/REM sleep stages, mood, energy, alertness, and daily activity and productivity. Another study found that MgT supplementation improved sleep behaviour, mood, and mental alertness.
MgT has also been found to enhance cognitive function and improve memory. In a randomized, double-blind, placebo-controlled study, healthy Chinese adults who took Magtein®, a magnesium L-threonate-based formula, showed significant improvements in all five subcategories of "The Clinical Memory Test" compared to a placebo group. Older participants showed more improvement than younger ones, suggesting that MgT may be particularly beneficial for memory and cognition in older adults.
Additionally, MgT has been found to boost overall brain health and cognitive processing. MIT researchers discovered that MgT can increase the density of synapses, which are the communication connections between brain cells. This increase in synaptic density can lead to improved cognitive processing and enhanced brain function. MgT has also been found to reduce brain age by more than nine years in adults with early cognitive impairment, further highlighting its potential for improving brain health and function.
While magnesium glycinate is a more common and budget-friendly option for addressing magnesium deficiency, magnesium L-threonate stands out for its unique ability to cross the blood-brain barrier, making it a superior choice for improving sleep quality, enhancing memory, and boosting cognitive function.
