Beef gelatin is protein that is derived from boiling water and cow parts, such as ligaments, bones, tissue and skins. The extracted gel-like substance, which is odorless and tasteless, is utilized in food products, cosmetics, shampoos, and as a coating for medicines and vitamins.
Pig byproducts are also often used to make gelatin. Gelatin has extensive uses, especially in food products. Gelatin is useful as a thickening agent for pudding and other gel-like desserts.
Because gelatin contains collagen or protein, many people use it as a supplement for conditions such as osteoarthritis and osteoporosis. People also utilize it to strengthen nails and improve the quality of hair. However, there is insufficient evidence that gelatin can be effective for any of these purposes.
