Since gelatin is denatured collagen, it might just improve your body's own collagen levels. However, if gelatin is not your snack of choice, you can also use gelatine or gelatine hydrolysate supplements in pill or liquid form.
Even though your body may not produce the same levels of collagen as it once did, stimulating your collagen production has the potential to reverse some signs of aging. It might be easy to jump to the conclusion that taking collagen supplements for your skin would help, just as you can take calcium supplements to maintain strong bones.
However, the solution isn't as simple in the case of collagen, because you're trying to affect the way your body produces a protein, not just the way it absorbs a mineral. Collagen supplements come in pill and liquid form, and because collagen is found in your skin, bones and cartilage, you can combine it with other supplements. Collagen supplements may be mixed with glucosamine or chondroitin, two supplements used for joint and arthritis problems.
Since collagen gives cartilage its strength, it can also be helpful for those suffering from osteoarthritis [source: WebMD]. However, if you don't have joint problems, you might want to opt for collagen hydrolysate or collagen peptide supplements instead. Additionally, if you decide to give collagen supplements a try, you should also boost your vitamin C intake, as vitamin C helps the body produce collagen [source: Medline Plus].
As with any treatment, how soon someone see results after taking collagen supplements will vary from person to person. Be aware that dietary supplements are not regulated by the United States Food and Drug Administration (FDA), and they do not undergo the same testing as prescription drugs. If you are not sure whether taking a collagen supplement is right for you, ask your doctor.
If taking a pill doesn't sound right for you, perhaps a topical treatment is more acceptable. Read on to find out about collagen boosting creams.
