Gelatin is a protein made from animal products.
Gelatin is used for weight loss and for treating osteoarthritis, rheumatoid arthritis, and brittle bones (osteoporosis). Some people also use it for strengthening bones, joints, and fingernails. Gelatin is also used for improving hair quality and to shorten recovery after exercise and sports-related injury.
In manufacturing, gelatin is used for preparation of foods, cosmetics, and medicines.
How does it work?
Insufficient Evidence to Rate Effectiveness for...
- A kind of arthritis called osteoarthritis. There is some clinical evidence that gelatin might relieve pain and improve joint function in patients with osteoarthritis.
- Brittle bones (osteoporosis).
- Strengthening bones and joints.
- Strengthening fingernails.
- Improving hair quality.
- Weight loss.
- Shortening recovery after exercise and sports-related injury.
- Other conditions.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
Gelatin is LIKELY SAFE for most people in food amounts and POSSIBLY SAFE in the larger amounts used as medicine. There's some evidence that gelatin in doses up to 10 grams daily can be safely used for up to 6 months.
There is some concern about the safety of gelatin because it comes from animal sources. Some people are worried that unsafe manufacturing practices might lead to contamination of gelatin products with diseased animal tissues including those that might transmit mad cow disease (bovine spongiform encephalopathy). Although this risk seems to be low, many experts advise against using animal-derived supplements like gelatin.
The appropriate dose of gelatin depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for gelatin. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
