Gelatin comes from collagen and is a protein. Its unusual composition of amino acids provides significant health benefits. Researchers have found that gelatin helps keep joints flexible, supports cognitive health, and even has the potential to make skin and hair look better. Soups, broths, sauces, gummy candies, marshmallows, cosmetics, and pharmaceuticals all frequently use gelatin as a component. This frequent gelling agent is derived from animal sources and is therefore very protein-rich. Read on to find out if gelatin is good for your health and who should probably stay away from it. Collagen from animals, most commonly cows and pigs, is used to create the protein known as gelatin. Capsules, cosmetics, ointments, and foods all benefit from its incorporation. Collagen is a structural protein found in skin, bone, and cartilage. It's possible that ingesting gelatin can stimulate more collagen synthesis in the body.
