C-Jello Collagen Jelly Bar is made of hydrolysed German Fish Collagen, a marine-based collagen. They are wild caught fishes from the deep oceans such as cod, haddock and pollock. These fishes are free from growth hormones or antibiotics. When collagen is hydrolysed, protein molecules are broken down into smaller molecules, and are absorbed faster into the body. Collagen is the building block of our bones, skin and muscles and C-Jello promotes stronger ligament and joints, healthier hair and stronger nails, and improves overall health. C-Jello Collagen Jelly Bar is gluten-free, dairy-free and egg-free.
