The appropriate use of gelatin for pain depends on the patient's age and other health conditions, states WebMD. As of 2014, there is insufficient scientific evidence available to recommend a gelatin dosage, although some evidence indicates that it is safe to take up to 10 grams daily for six months.
Made from animal products, gelatin is a protein that is sometimes used for weight loss and treatment of osteoarthritis, rheumatoid arthritis and osteoporosis, according to WebMD. Some people also use it to improve hair quality, shorten recovery time after exercise or sports injuries, and strengthen fingernails, joints and bones. As of 2014, more scientific evidence is needed to determine the effectiveness of gelatin for any of these uses.
Gelatin is considered likely safe in food amounts and possibly safe in larger medicinal doses, according to WebMD. Sometimes it causes heaviness in the stomach, an unpleasant taste in the mouth, heartburn, belching and bloating. Some concern has been raised pertaining to the safety of gelatin because it is an animal product. It is possible that improper manufacturing procedures can lead to contamination of gelatin with animal tissues containing diseases, such as mad cow disease. The risk of contamination appears low, but many experts still believe that animal-derived supplements such as gelatin should be avoided.
