Mechanism of Action +
### The Biochemistry of Manganese
Manganese is an essential trace element required for the proper functioning of multiple physiological processes, primarily acting as a catalytic cofactor or structural component for a variety of critical enzymes. In the human body, manganese is concentrated in the mitochondria, bones, liver, kidneys, and pancreas. Its biochemical roles can be categorized into antioxidant defense, metabolic regulation, and connective tissue synthesis.
#### Mitochondrial Antioxidant Defense: Manganese Superoxide Dismutase (MnSOD) One of the most vital roles of manganese is its function as the active metal center in Manganese Superoxide Dismutase (MnSOD or SOD2). Located exclusively within the mitochondrial matrix, MnSOD is the primary antioxidant enzyme responsible for scavenging superoxide radicals generated as a byproduct of the electron transport chain during oxidative phosphorylation. By catalyzing the dismutation of the highly reactive superoxide anion into hydrogen peroxide and diatomic oxygen, manganese protects mitochondrial DNA, proteins, and lipid membranes from oxidative damage. This mechanism is crucial for cellular longevity, energy production, and mitigating oxidative stress in high-demand tissues like skeletal and cardiac muscle.
#### Connective Tissue and Cartilage Synthesis Manganese is an obligate cofactor for glycosyltransferases, a family of enzymes responsible for the synthesis of proteoglycans and glycosaminoglycans (GAGs). These complex carbohydrates are the primary structural components of the extracellular matrix in cartilage, bone, and connective tissue. Specifically, manganese facilitates the transfer of sugar moieties from nucleotide sugars to the growing carbohydrate chain. This biochemical pathway explains why manganese is frequently included in premium joint support matrices alongside glucosamine, chondroitin, and MSM. Without adequate manganese, the structural integrity of articular cartilage is compromised, leading to impaired joint recovery and increased susceptibility to mechanical wear.
#### Metabolic and Neurological Pathways Manganese also serves as a cofactor for several key metabolic enzymes: 1. **Pyruvate Carboxylase**: Essential for gluconeogenesis, converting pyruvate to oxaloacetate in the liver. 2. **Arginase**: The final enzyme in the urea cycle, responsible for converting arginine to urea and ornithine, facilitating the detoxification of ammonia. 3. **Glutamine Synthetase**: Highly concentrated in the brain, this enzyme converts glutamate (an excitatory neurotransmitter) and ammonia into glutamine, playing a critical role in neurotransmitter recycling and neuroprotection.
### The TRAACS® Chelation Technology
The absorption of inorganic trace minerals (such as manganese sulfate or manganese oxide) is notoriously inefficient. Inorganic minerals dissociate in the acidic environment of the stomach, leaving the free metal cation vulnerable to binding with dietary inhibitors like phytates, oxalates, and tannins, which form insoluble, unabsorbable complexes. Furthermore, free mineral cations must compete for uptake through the Divalent Metal Transporter 1 (DMT1) in the intestinal lumen, leading to competitive inhibition between minerals like iron, zinc, calcium, and manganese.
TRAACS® (The Real Amino Acid Chelate System), developed by Albion Minerals (now Balchem), solves these pharmacokinetic limitations through true amino acid chelation.
#### Coordinate Covalent Bonding In a TRAACS® manganese bisglycinate chelate, a single manganese atom is bound to two molecules of the amino acid glycine. The amino and carboxyl groups of the glycine molecules form coordinate covalent bonds with the manganese ion, creating a stable, heterocyclic ring structure. Glycine is selected as the optimal ligand due to its low molecular weight, which ensures the entire chelate molecule is small enough to be efficiently absorbed.
#### Pharmacokinetics and Dipeptide Transport Because the manganese ion is fully enclosed within the glycine rings, the molecule carries a neutral charge. This structural stability protects the mineral from the acidic pH of the stomach and prevents it from interacting with dietary antagonists in the gastrointestinal tract.
Upon reaching the small intestine (specifically the jejunum), the manganese bisglycinate chelate does not rely on the easily saturated DMT1 pathway. Instead, the body recognizes the chelate as a dipeptide (a small protein fragment). It is actively transported across the enterocyte membrane via the Peptide Transporter 1 (PEPT1) pathway. This alternative absorption route is highly efficient, requires less energy, and completely bypasses the competitive mineral absorption bottlenecks.
Once inside the mucosal cell, cytoplasmic enzymes hydrolyze the chelate, releasing the free manganese for transport into the bloodstream via transferrin or alpha-2-macroglobulin, while the glycine is utilized for normal cellular metabolism or protein synthesis. This targeted delivery system results in significantly higher cellular uptake, lower required dosages, and the elimination of gastrointestinal side effects commonly associated with unchelated mineral supplements.

Everything About Manganese (as TRAACS® Manganese Glycinate Chelate) Article
## The Definitive Guide to Manganese (as TRAACS® Manganese Glycinate Chelate)
When evaluating sports nutrition and clinical joint support formulas, trace minerals are often overlooked in favor of macronutrients or high-dose botanicals. However, trace minerals like manganese are the biological spark plugs that allow these larger systems to function. Manganese is an essential cofactor for antioxidant defense, metabolic regulation, and, most notably for athletes, the synthesis of connective tissue.
But not all manganese is created equal. The form in which a mineral is delivered dictates whether it will be absorbed by your cells or flushed down the toilet. Enter **TRAACS® Manganese Glycinate Chelate**—the gold standard in mineral delivery technology.
### What is TRAACS®?
TRAACS® stands for **The Real Amino Acid Chelate System**. Developed by Albion Minerals (now a part of Balchem), this patented technology solves the fundamental problem of mineral supplementation: poor bioavailability.
In nature, minerals are inorganic elements. When you consume cheap mineral salts like manganese sulfate or manganese oxide, they enter the acidic environment of your stomach and dissociate into free ions. These free ions are highly reactive. They bind to dietary inhibitors like phytates (found in grains), oxalates (found in leafy greens), and tannins (found in tea and coffee), forming insoluble complexes that your body cannot absorb. Furthermore, free mineral ions must compete with one another—iron, zinc, calcium, and manganese all fight for the same limited absorption doorways (like the DMT1 transporter) in the intestinal wall.
Albion's TRAACS® technology circumvents this entirely. Through a precise, patented process, a single manganese ion is chemically bound (chelated) to two molecules of the amino acid glycine. This creates a stable, neutral, heterocyclic ring.
Because the manganese is "hidden" inside the amino acids, it does not react with dietary inhibitors. More importantly, the intestines recognize the molecule not as a mineral, but as a dipeptide (a small protein). It is actively absorbed through the PEPT1 peptide transport pathway, completely bypassing the competitive mineral bottlenecks. The result is unparalleled absorption, zero gastrointestinal distress, and maximum cellular delivery.
### Why Athletes and Active Individuals Need Manganese
While manganese is involved in over 300 biological processes, its role in sports nutrition primarily centers around two critical functions: joint repair and antioxidant defense.
#### 1. The Architect of Cartilage If you look at premium joint support products—such as NutraBio's Glucosamine Chondroitin MSM matrix—you will almost always find manganese included at a dose of 1mg to 2mg. This is not an accident.
Manganese is an obligate cofactor for a family of enzymes called glycosyltransferases. These enzymes are the construction workers of your joints. They are responsible for taking the raw materials (like glucosamine and chondroitin) and assembling them into proteoglycans and glycosaminoglycans (GAGs). These complex structures form the shock-absorbing extracellular matrix of your articular cartilage.
Without adequate manganese, supplementing with high doses of glucosamine is like delivering bricks to a construction site with no bricklayers. The raw material is there, but the structural assembly is impaired. By providing highly bioavailable TRAACS® Manganese, you ensure that the enzymatic machinery required for joint repair is fully optimized.
#### 2. Mitochondrial Antioxidant Defense (MnSOD) Intense physical training generates massive amounts of oxidative stress, particularly within the mitochondria (the powerhouses of the cell). As the electron transport chain churns out ATP to fuel your muscles, it also leaks superoxide radicals—highly damaging reactive oxygen species.
Manganese is the active metal center of **Manganese Superoxide Dismutase (MnSOD)**, the primary antioxidant enzyme located inside the mitochondria. MnSOD neutralizes these superoxide radicals, converting them into less harmful molecules. By maintaining robust MnSOD activity, manganese helps protect cellular machinery from exercise-induced oxidative damage, supporting better endurance, faster recovery, and overall cellular longevity.
### The Albion Minerals Difference
The supplement industry is rife with products making unfounded claims. Many companies use the word "chelate" loosely, simply mixing inorganic minerals with amino acids in a vat and hoping for the best. This results in "complexes" that fall apart in the stomach.
Albion Minerals set the industry standard by being the first to scientifically prove the molecular structure of their chelates. Using cutting-edge technologies like Fourier Transform Infrared Spectroscopy (FT-IR) and X-ray crystallography, Albion validates that coordinate covalent bonds have actually formed between the mineral and the amino acid ligand.
Their total mineral portfolio is supported by over 160 scientific publications and nearly 80 human clinical trials. When you see the TRAACS® logo on a supplement facts panel, you are guaranteed a nanoparticle-free, fully reacted amino acid chelate that delivers exactly what it promises.
### Dosage and Synergies
The clinical standard for supplemental manganese in joint formulas is typically **1mg to 2mg per day**. Because TRAACS® Manganese Glycinate Chelate is so highly bioavailable, massive doses are not required. In fact, the median dose found in top-tier clinical joint matrices is exactly 1mg.
Manganese works synergistically with: * **Glucosamine Sulfate**: Provides the structural backbone for cartilage. * **Chondroitin Sulfate**: Draws water into the joint matrix for lubrication. * **MSM**: Provides the sulfur bonds necessary for connective tissue strength. * **Vitamin C**: Required for collagen synthesis, complementing manganese's role in proteoglycan formation.
### Safety and Interactions
TRAACS® Manganese Glycinate Chelate is exceptionally safe and well-tolerated. Because it is bound to glycine, it is gentle on the stomach and does not cause the nausea or cramping sometimes associated with cheap mineral oxides.
However, like all minerals, it should be timed correctly if you are taking certain medications. If you are prescribed thyroid medication (like levothyroxine), certain antibiotics (tetracyclines or quinolones), or bisphosphonates for bone health, you should separate your mineral supplements from your medication by at least two hours. Even chelated minerals can potentially interact with the absorption of these specific drugs.
### The Bottom Line
When it comes to trace minerals, the delivery system is just as important as the nutrient itself. TRAACS® Manganese Glycinate Chelate represents the pinnacle of mineral science. Whether you are an athlete looking to bulletproof your joints, or simply seeking to optimize your cellular antioxidant defenses, looking for the TRAACS® trademark on your supplement label ensures you are getting a product that your body can actually use.
