Many potential benefits of gelatin remain unproven, including relief of joint pain, growing stronger finger nails, and making one’s hair healthier. Generally, however, researchers agree that gelatin is safe for most people to consume. Side effects of heavy consumption may include heartburn, bloating, and gas. Some people are allergic to gelatin and therefore should not attempt to use it as a supplement. It is generally recommended that a person see a doctor before starting a new diet or supplement.
While not among the proven benefits of gelatin, some doctors report that gelatin is effective for improving joint health. Athletes who took gelatin supplements found noticeable relief in their knee pain and stiffness, though it is unclear whether the pain relief was actual relief brought on by gelatin, coincidence, or a placebo effect. Gelatin supplements can be found in drug and vitamin stores or purchased online, and does not require a doctor’s prescription.
Other unproven benefits of gelatin include strengthening of the hair and nails, weight loss, and the treatment of brittle bones. As of early 2012, these benefits lack sufficient evidence to conclude whether or not they can be brought on by consuming gelatin. With guidance from a doctor, it might not be harmful to attempt treatment with gelatin supplements.
Some side effects of gelatin include heartburn, an unpleasant taste in the mouth, and bloating of the stomach area. Most experts consider gelatin likely safe in food amounts, but possibly less safe when heavily consumed as a remedy; however, gelatin is derived from the tissue of dead animals, and there is a small chance of the final product being contaminated by disease. Generally, however, this chance is so insignificant that gelatin is consumed without worry in many countries.
Most people with gelatin allergies experience mild symptoms, such as hives, while severe reactions are becoming increasingly common, especially in Asian countries. Low blood pressure, lightheadedness, and anaphylaxis are severe reactions to gelatin that require immediate treatment. Gelatin is used in a wide variety of products and medicines, like vaccines, gel tablets and gelatin desserts, so it can be difficult to avoid the substance.
It is important to explore the disadvantages and benefits of gelatin with a doctor before starting treatment. The benefits may not be enough to outweigh its disadvantages, especially if a person has a gelatin allergy. There may also be other, more effective methods of treatment depending on the ailment.
