🧪 Formulation Notes

Collagen Joint Support Powder is a combination of ingredients that help to support the formation and function of healthy joint tissue. This product uses hydrolyzed collagen that has been enzymatically treated for ease of absorption, as well as MSM (methylsulfonylmethane), a biologically active form of sulfur, that serves as building blocks for collagen synthesis. Glucosamine is included as an essential structural component that is naturally present in bones and joints. Numerous scientific studies have demonstrated that glucosamine can help to support healthy joint structures and promote joint comfort.
