🧪 Formulation Notes

50% more potent

Promotes healthy joints

Source Naturals Glucosamine Chondroitin provides important building blocks for healthy joints and connective tissues. Glucosamine, an amino sugar, is an essential structural component of glycosaminoglycans, large linear molecules that help to lubricate joints. Manganese and vitamin C are involved in the synthesis of collagen, and chondroitin sulfate lends additional structural support via its high degree of interaction with collagen fibers. Molybdenum aids in complete metabolism of glucosamine and chondroitin.

Contains no yeast, dairy, egg, gluten, soy or wheat. Contains no starch, preservatives, or artificial color, flavor or fragrance.
