Pharmaceutical Gelatin: Gelatin is used to make the shells of hard and soft capsules for medicines, dietary/health supplements, syrups, tablet sugar-coat, vitamin nutrition base frosting, soft adhesive powder, bio-pharmaceuticals, etc. It is highly digestible and serves as a natural protective coating for medications. The gelatin layer protects against sunlight and oxygen, thereby giving the medicine a longer shelf life. But the layer also ensures that medicines can be easily and safely swallowed and that the active components are released in the correct part of the digestive tract.
