What it is: Glucosamine + Chondroitin with Manganese is a three-ingredient joint and cartilage support formula developed by Pure Encapsulations®, delivering Glucosamine HCl (500 mg, from crab and shrimp), Chondroitin Sulfate (400 mg, from bovine cartilage), and Manganese (2 mg, as manganese ascorbate) per vegetarian capsule. This hypoallergenic formula is free of gluten, dairy, soy, and artificial additives — consistent with Pure Encapsulations®' foundational commitment to clean, allergen-conscious supplementation. The three-ingredient combination targets the structural and metabolic requirements of articular cartilage from complementary angles — providing the biosynthetic building blocks for cartilage matrix synthesis, the proteoglycan ground substance that maintains joint cushioning and lubrication, and the trace mineral cofactor required for glycosaminoglycan and collagen production. Designed for practitioner-directed use in joint health and cartilage support protocols, this formula has been part of the Pure Encapsulations® line since its introduction in 2001.
How it works: Glucosamine + Chondroitin with Manganese supports cartilage integrity, joint comfort, and connective tissue health through three mechanistically complementary and synergistic pathways. Glucosamine HCl (500 mg, from crab and shrimp) serves as a direct biosynthetic building block and rate-limiting substrate for the endogenous synthesis of glycosaminoglycans — including chondroitin sulfate — and hyaluronic acid within articular cartilage and synovial fluid. Studies have indicated that Glucosamine HCl supports healthy cartilage integrity in part by maintaining healthy matrix metalloproteinase (MMP) enzyme activity, which governs cartilage matrix remodeling and degradation balance. Chondroitin Sulfate (400 mg, from bovine cartilage) is the primary glycosaminoglycan responsible for building the proteoglycan ground substance of cartilage — large aggregating molecules that attract and retain water within the cartilage matrix, providing the compressive resilience and hydration necessary for load-bearing joint function. Chondroitin sulfate additionally inhibits the catabolic enzymes responsible for cartilage matrix breakdown and supports healthy inflammatory balance within joint tissue. Manganese (2 mg, as manganese ascorbate) provides the trace mineral cofactor essential for glycosaminoglycan and mucopolysaccharide synthesis — the sugar-protein scaffolding of cartilage and connective tissue — and supports the antioxidant activity of manganese superoxide dismutase (MnSOD), the primary mitochondrial antioxidant enzyme protecting chondrocytes and joint tissue from oxidative damage. The ascorbate form of manganese also delivers Vitamin C activity that is essential for collagen cross-linking and provides additional antioxidant protection within the joint environment.
When to use it: Glucosamine + Chondroitin with Manganese is appropriate for practitioner-directed use in adult clients requiring comprehensive cartilage matrix support, joint comfort, and connective tissue integrity — particularly those experiencing age-related cartilage wear, reduced joint mobility, or elevated physical activity demands on weight-bearing joints. Pure Encapsulations® recommends an initial loading protocol of three capsules daily in divided doses with meals for two to three weeks, followed by a maintenance protocol of two capsules daily in divided doses with meals — a flexible dosing structure that accommodates individualized clinical titration. As this formula contains crustacean shellfish (crab, shrimp), it is contraindicated in clients with shellfish allergies. Use with caution in clients taking anticoagulant medications, and consult a healthcare practitioner before use during pregnancy or lactation. Rare mild gastrointestinal symptoms may occur — taking with food minimizes this risk.

Key Ingredients
Glucosamine HCl (from crab, shrimp) — 500 mg Glucosamine HCl is the hydrochloride salt form of glucosamine, derived from crustacean shellfish (crab and shrimp) and recognized as one of the most clinically studied forms of supplemental glucosamine for joint health support — with a more concentrated elemental glucosamine content per unit weight compared to glucosamine sulfate, providing a higher absolute glucosamine dose per 500 mg capsule. As a direct biosynthetic building block and rate-limiting substrate for chondroitin sulfate and hyaluronic acid synthesis within articular cartilage and synovial fluid, Glucosamine HCl supports the anabolic repair and maintenance of cartilage matrix through chondrocyte proteoglycan and aggrecan synthesis. Published studies indicate that Glucosamine HCl supports healthy cartilage integrity in part by maintaining healthy matrix metalloproteinase (MMP) enzyme activity — the enzymatic system governing cartilage matrix remodeling balance — supporting joint comfort and mobility through substrate-driven matrix maintenance.
Chondroitin Sulfate (from bovine) — 400 mg Chondroitin Sulfate is a sulfated glycosaminoglycan derived from bovine cartilage, providing the primary structural glycosaminoglycan responsible for building the proteoglycan ground substance of articular cartilage — the large aggregating macromolecules that attract and retain water within the cartilage matrix to provide the compressive resilience, cushioning, and hydration necessary for load-bearing joint function. Beyond its structural role, Chondroitin Sulfate inhibits the activity of cartilage-degrading enzymes including matrix metalloproteinases and aggrecanases, suppresses IL-1β-driven catabolic gene expression in chondrocytes, and provides direct biosynthetic substrate for cartilage repair — addressing both the anabolic and anti-catabolic dimensions of cartilage maintenance simultaneously. At 400 mg per capsule, this bovine-sourced Chondroitin Sulfate provides a meaningful structural glycosaminoglycan dose that complements the biosynthetic pathway support of Glucosamine HCl, collectively addressing the cartilage matrix from both substrate provision and structural replenishment angles.
Manganese (as Manganese Ascorbate) — 2 mg Manganese ascorbate is an organic salt form of manganese delivering this trace mineral alongside ascorbate — the bioavailable anion of Vitamin C — providing the mineral as an efficiently absorbed form with complementary antioxidant co-factor activity from the ascorbate component. Manganese is a required cofactor for the glycosyltransferase enzymes responsible for glycosaminoglycan and mucopolysaccharide biosynthesis within articular cartilage and connective tissue — directly supporting the synthesis of chondroitin sulfate, proteoglycans, and collagen that constitute the structural extracellular matrix of joint tissue. Additionally, manganese is the specific metallic cofactor for manganese superoxide dismutase (MnSOD) — the primary mitochondrial antioxidant enzyme protecting chondrocytes from the reactive oxygen species generated during inflammatory joint stress — making adequate manganese status essential for both cartilage matrix anabolism and chondrocyte oxidative protection within a comprehensive joint support protocol.
