Paradise Collagen Essence uses patented BioCell Collagen synergized with our Natures C and poly 25 ( He Shou Wu formula) for optimal support for the joints, hair and skin. BioCell Collagen is a more expensive and rarer type II collagen sourced from chicken sternal cartilage. It does not contain Cow or Pig. It naturally provides bioavailable hyaluronic acid, (partly responsible for the skin's moisture, suppleness and elasticity).Chondroitin Sulfate, and small amounts of glucosamine. Our Natures C is sourced from quality amla fruits and our Poly 25 Shou Wu formula is based on traditional herbs that have been used for thousands of years to support healthy hair, skin, joints, back and knees.
