Our cartilage-based blend is rich in bioactive growth factors and vital amino acids that work synergistically with collagen type II for optimal joint, hair, nail, and skin health. Our grass fed bovine "living" collagen is sourced from the cartilaginous parts of the animal, including the trachea and scapula. As such, our whole-food collagen retains the ancestral properties our DNA still expects today to express vibrant health and wellness.
