Magnesium Bisglycinate Chelate (TRAACS®)
Mechanism of Action +
### The Biochemistry of Magnesium Magnesium is the fourth most abundant mineral in the human body and the second most abundant intracellular cation after potassium. It serves as an obligatory cofactor for over 300 enzymatic reactions, primarily those involving the transfer of phosphate groups. Every molecule of ATP (adenosine triphosphate) synthesized or consumed in the body must bind to a magnesium ion to form a biologically active Mg-ATP complex. Without magnesium, ATP is highly unstable and biologically inert. Beyond cellular energy metabolism, magnesium is critical for the structural integrity of nucleic acids, proteins, and mitochondria. It regulates ion channels, particularly the calcium channels in muscle and nerve cells, acting as a natural calcium antagonist to facilitate muscle relaxation and prevent neuronal excitotoxicity.
### The Chelation Advantage: TRAACS® Technology The fundamental challenge with mineral supplementation is bioavailability. Inorganic magnesium salts, such as magnesium oxide or magnesium sulfate, dissociate rapidly in the acidic environment of the stomach. The resulting free magnesium ions carry a high hydration energy, meaning they attract and bind to water molecules in the intestinal lumen. This osmotic effect is the primary cause of the laxative effect (diarrhea) associated with cheap magnesium supplements. Furthermore, free magnesium ions must compete with other divalent cations (like calcium, zinc, and iron) for uptake through the Transient Receptor Potential Melastatin (TRPM6 and TRPM7) ion channels in the enterocytes.
TRAACS® (The Real Amino Acid Chelate System), developed by Albion Minerals (now Balchem), solves this via true molecular chelation. In magnesium bisglycinate chelate, one magnesium atom is bound to the carboxyl and amino groups of two glycine molecules, forming a stable, heterocyclic ring structure. This neutralizes the ionic charge of the magnesium. Because the molecule is electrically neutral, it does not attract water in the gut, virtually eliminating osmotic diarrhea.
### Pharmacokinetics and Dipeptide Transport Because the magnesium is hidden within the amino acid structure, the gastrointestinal tract recognizes the chelate as a dipeptide rather than a free mineral. This allows the compound to bypass the easily saturated TRPM6/7 ion channels. Instead, it is absorbed via the highly efficient PEPT1 (Peptide Transporter 1) channels located in the brush border of the small intestine. This alternative absorption pathway significantly increases the fractional absorption rate of magnesium, making bisglycinate one of the most bioavailable forms available. Once inside the enterocyte and systemic circulation, cytoplasmic enzymes gradually hydrolyze the chelate, releasing the elemental magnesium and free glycine into the bloodstream.
### Glycine's Synergistic Neurological Role The dissociation of magnesium bisglycinate yields a secondary bioactive compound: glycine. Glycine is a non-essential amino acid that functions as a major inhibitory neurotransmitter in the brainstem and spinal cord. It also acts as a co-agonist at the NMDA (N-methyl-D-aspartate) receptors in the brain. While glutamate activates NMDA receptors (causing excitation), magnesium physically blocks the NMDA receptor pore, preventing excessive calcium influx and neuronal excitotoxicity. The simultaneous delivery of magnesium (the NMDA blocker) and glycine (the inhibitory neurotransmitter) creates a powerful synergistic effect that calms the central nervous system, lowers core body temperature, and facilitates the onset of sleep.
### Cardiovascular and Metabolic Mechanisms In the cardiovascular system, magnesium regulates vascular tone. By competing with calcium for binding sites on voltage-dependent calcium channels in smooth muscle cells, magnesium prevents excessive intracellular calcium accumulation. This induces vasodilation, reducing peripheral vascular resistance and lowering blood pressure—a mechanism supported by robust clinical data in hypertensive individuals. Metabolically, magnesium is required for the autophosphorylation of the insulin receptor. Intracellular magnesium deficiency impairs insulin signaling, leading to insulin resistance. Supplementation restores receptor sensitivity, improving glucose disposal and glycemic control in populations with metabolic syndrome or type 2 diabetes.

Everything About Magnesium Bisglycinate Chelate (TRAACS®) Article
## The Ultimate Guide to Magnesium Bisglycinate Chelate (TRAACS®)
Magnesium is the unsung hero of human biochemistry. Involved in over 300 enzymatic reactions, it is the biological key that unlocks cellular energy, regulates muscle contraction, and maintains the delicate electrical balance of our nervous system. Yet, despite its critical importance, magnesium represents the second most common micronutrient deficiency in the developed world, trailing only behind Vitamin D.
Modern agricultural practices have depleted the soil of its natural mineral content, and the heavy processing of modern diets strips away what little magnesium remains. Consequently, supplementation is no longer just an option for many—it is a necessity. However, the world of magnesium supplements is fraught with cheap, poorly absorbed forms that do more to upset your stomach than they do to improve your health. Enter Magnesium Bisglycinate Chelate, specifically the patented TRAACS® form by Albion Minerals.
## The TRAACS® Difference: What is a True Chelate?
If you have ever taken a cheap magnesium supplement and spent the rest of the day running to the bathroom, you have experienced the pitfalls of inorganic magnesium salts. Forms like magnesium oxide and magnesium sulfate are highly unstable in the acidic environment of the stomach. When they break down, they release free magnesium ions. These ions are highly hydrophilic—they attract water. As they travel through your intestines, they pull water from your body into the bowel, resulting in osmotic diarrhea.
TRAACS® stands for "The Real Amino Acid Chelate System." Developed by Albion Laboratories (now Balchem), this patented technology solves the absorption problem through molecular chelation. In this process, a single magnesium ion is covalently bound to two molecules of the amino acid glycine.
This creates a stable, ring-like structure that neutralizes the electrical charge of the magnesium. Because it is electrically neutral, it does not attract water in the gut, virtually eliminating the laxative effect. Furthermore, the body does not recognize this molecule as a mineral; it recognizes it as a dipeptide (a small protein). This allows the magnesium bisglycinate to bypass the standard, easily saturated mineral ion channels and instead be absorbed through highly efficient peptide transporters (PEPT1) in the intestinal wall.
## Clinical Evidence and Health Benefits
### 1. Cardiovascular Health and Blood Pressure According to the Examine.com database, one of the most robust, highly-graded (Grade B) benefits of magnesium supplementation is its ability to lower blood pressure. Magnesium acts as a natural calcium channel blocker. In smooth muscle cells lining the blood vessels, calcium causes contraction (vasoconstriction), while magnesium facilitates relaxation (vasodilation). Large meta-analyses have confirmed that magnesium supplementation significantly reduces both systolic and diastolic blood pressure, particularly in individuals who are already hypertensive or deficient in the mineral.
### 2. Glycemic Control and Insulin Sensitivity Magnesium plays an obligatory role in carbohydrate metabolism. The insulin receptor on your cells requires magnesium to function properly (a process called autophosphorylation). When intracellular magnesium levels drop, the receptor becomes deaf to insulin's signals, leading to insulin resistance. Clinical trials show that restoring magnesium levels via supplementation improves glucose disposal and enhances insulin sensitivity, making it a critical nutrient for those managing metabolic syndrome or type 2 diabetes.
### 3. Sleep Quality and Nervous System Regulation Magnesium bisglycinate is widely regarded as the best form of magnesium for sleep, and for good reason—it delivers a two-pronged approach to nervous system relaxation. First, the magnesium physically blocks NMDA receptors in the brain, preventing excitatory neurotransmitters like glutamate from overstimulating the nervous system. Second, as the chelate breaks down, it releases glycine. Glycine is an inhibitory neurotransmitter that lowers core body temperature and calms the brainstem. While Examine grades the evidence for sleep as "Moderate to Low" (Grade C) due to small sample sizes, the practical, real-world efficacy of magnesium bisglycinate for improving sleep architecture is profound, particularly in the elderly or those under high stress.
### 4. Muscle Cramps: Fact vs. Fiction Magnesium is heavily marketed as a cure for exercise-induced muscle cramps. However, clinical data paints a more nuanced picture. Examine notes that while magnesium is highly effective for treating leg cramps associated with pregnancy, the evidence does not strongly support its use for acute, exercise-induced cramping in athletes who are not deficient. Cramping during exercise is more often related to neuromuscular fatigue or sodium depletion. That said, maintaining adequate baseline magnesium is essential for overall muscle function and recovery.
## Dosage Guidelines and Label Literacy
The recommended daily allowance (RDA) for magnesium is roughly 400-420mg for adult men and 310-320mg for adult women. Clinical studies typically use doses ranging from 200mg to 400mg of **elemental** magnesium daily.
This is where label literacy becomes critical. Magnesium bisglycinate chelate is a large molecule, and the elemental magnesium only makes up about 10% to 14% of the total weight. Therefore, to get 200mg of actual, elemental magnesium, you need to consume roughly 1,500mg to 2,000mg of the magnesium bisglycinate compound.
**Red Flag:** If a supplement label says "Magnesium Bisglycinate - 400mg" and does not specify the elemental yield, you are likely only getting about 40mg of actual magnesium per serving. Always look for labels that explicitly state the elemental magnesium content.
## Synergy: The Vital Trio and Creatine
Magnesium does not work in isolation. It is a critical component of the "Vital Trio"—Magnesium, Vitamin D3, and Vitamin K2. Magnesium is required by the liver and kidneys to convert inactive Vitamin D into its active hormonal form (calcitriol). Once active, Vitamin D increases calcium absorption. Vitamin K2 then acts as the traffic cop, directing that calcium into the bones and teeth, preventing it from calcifying in the arteries. Without magnesium, this entire biological cascade fails.
Additionally, athletes should note that ATP (the energy currency of the cell) must bind to magnesium to be biologically active. Because creatine works by increasing cellular ATP stores, ensuring adequate magnesium levels is essential for maximizing the benefits of creatine supplementation. Albion Minerals even produces a specific compound, Creatine MagnaPower®, to capitalize on this synergy.
## Safety, Side Effects, and Contraindications
Magnesium bisglycinate is exceptionally safe and boasts the highest gastrointestinal tolerance of any magnesium form. The Mayo Clinic notes that while high doses of generic magnesium can cause diarrhea, nausea, and GI irritation, the glycinate form minimizes these risks.
The primary contraindication for magnesium supplementation is **kidney disease**. The kidneys are responsible for excreting excess magnesium. If renal function is impaired, magnesium can build up in the blood, leading to hypermagnesemia, which can cause dangerous cardiac arrhythmias. Individuals with kidney disease should never supplement magnesium without strict medical supervision.
Furthermore, magnesium can bind to certain medications in the digestive tract, rendering them ineffective. If you are taking bisphosphonates (for osteoporosis) or certain classes of antibiotics (tetracyclines or fluoroquinolones), you must separate your magnesium dose from your medication by at least two hours.
## Conclusion
Magnesium Bisglycinate Chelate (TRAACS®) represents the pinnacle of mineral supplementation technology. By combining the essential physiological benefits of magnesium with the calming neurological effects of glycine, and wrapping it in a delivery system that guarantees absorption without digestive distress, it stands as the premier choice for correcting deficiencies, supporting cardiovascular health, and optimizing sleep.
