Andrew Lessman's Marine Collagen Peptides with MSM provides a unique source of highly soluble and absorbable collagen peptides, selected for their ability to deliver benefits to the vital collagen structure of our skin, hair, and nails, as well as to our joints, bones, and blood vessels. To further enhance and promote protein synthesis in these critical tissues, 500mg of methyl-sulfonyl-methane (MSM) is included as an exceptional source of highly bioavailable organic sulfur. These marine collagen peptides mix easily with water and are flavor-neutral, while also free of carbohydrates, sugar, lactose, fat, cholesterol, and sodium. It is non-GMO (not genetically modified) and contains no added flavors, sweeteners, or preservatives. Collagen is the primary structural protein in the body, comprising almost one-third of the body's entire protein mass. The healthy structure and function of our skin, bones, blood vessels, and connective tissues is built upon a foundation of collagen protein. The healthy appearance of our skin is dependent upon the integrating structure provided by collagen protein, which is why it is so often deceptively used in so many topical beauty products.
