Manganese is an essential trace mineral with a critical role as a cofactor for manganese superoxide dismutase (MnSOD) — the primary mitochondrial antioxidant enzyme — and a necessary component of the enzymes responsible for glycosaminoglycan synthesis, making it directly relevant to cartilage formation, bone development, and cellular antioxidant defence in dogs.
In both Bounce and Boost, manganese is provided as a chelate of glycine — a highly bioavailable form in which the mineral is bound to the amino acid glycine, protecting it from competing mineral interactions in the gut and supporting more consistent absorption compared to inorganic mineral salts.
An essential trace mineral cofactor — chelated to glycine for enhanced bioavailability — that activates glycosyltransferase enzymes essential for glycosaminoglycan synthesis in cartilage, functions as the core of mitochondrial MnSOD antioxidant defence, contributes to bone matrix formation, and supports multiple metabolic enzyme systems.
Manganese is a specific cofactor for glycosyltransferases — the enzymes that build glycosaminoglycan chains including chondroitin sulphate and heparan sulphate. Without adequate manganese, the production of these cartilage matrix components is impaired, making it a functionally relevant mineral in joint health formulations.
MnSOD (manganese superoxide dismutase) is the primary antioxidant enzyme in the mitochondria. It converts superoxide radicals — a byproduct of normal cellular energy production — into less harmful hydrogen peroxide, which is then further neutralised. Manganese is the metal centre essential for this enzyme’s activity.
Manganese also serves as a cofactor for arginase (in the urea cycle), pyruvate carboxylase (in energy metabolism), and several other enzymes involved in carbohydrate, amino acid, and fat metabolism, contributing to broad metabolic function.
Glycine chelation protects manganese from being displaced by competing divalent cations including calcium, iron, and zinc in the gastrointestinal tract, supporting more consistent absorption and reliable contribution to tissue manganese levels.
Science Informed Reasons to Include This Ingredient in Your Dog’s Diet:
Glycosaminoglycan Synthesis — manganese is required as a cofactor for glycosyltransferase enzymes that assemble glycosaminoglycan chains, making adequate manganese availability essential for the production of chondroitin sulphate and other cartilage matrix components supported by the joint health actives in the formulation.
Mitochondrial Antioxidant Defence — as the metal centre of MnSOD, manganese is integral to the primary mitochondrial antioxidant enzyme system, protecting cells from the oxidative byproducts of energy metabolism and contributing to healthy cellular function throughout the body.
Bone Matrix Formation — manganese contributes to the activity of enzymes involved in bone matrix synthesis and mineralisation, supporting skeletal health alongside calcium and the other bone-relevant nutrients in the formulations.
Cartilage Health Foundation — because manganese directly enables glycosaminoglycan synthesis, it acts as a foundational mineral for cartilage health, complementing the structural joint actives (glucosamine, chondroitin, hyaluronic acid) at the enzymatic level.
Energy Metabolism Support — manganese is a cofactor for pyruvate carboxylase (gluconeogenesis) and other metabolic enzymes, contributing to normal energy metabolism, blood glucose homeostasis, and cellular energy production.
Urea Cycle Function — manganese activates arginase, an enzyme in the urea cycle responsible for the conversion of arginine to ornithine and urea, supporting normal amino acid metabolism and nitrogen excretion.
Enhanced Bioavailability via Chelation — glycine chelation protects manganese from competing mineral interactions in the gastrointestinal tract and supports more efficient absorption, providing a more reliable means of meeting tissue manganese requirements compared to inorganic sulphate forms.
Directly Relevant to Both Formulations — in Bounce, manganese supports the enzymatic foundations of cartilage synthesis underlying the joint health stack. In Boost, it contributes to the broader mineral and antioxidant nutrient matrix of the whole-body wellness formulation.
