Listen in because what you know helps ensure healthy choices you can live with. Today on Healthy Talk, you wanted to know:Hello Dr. Mike, I'm a big fan of your show. First question is Carnosine. They say that it's a dipeptide, and I have learned that dipeptides are digested into amino acids. So, Carnosine will not survive as Carnosine in the digestion process. Is this supplement therefore a gimmick?Carnosine is naturally produced in your body, found mostly in your muscle tissue and brain. There is a synthetic form that is sold as a supplement and can be used as a natural way to help cure high blood pressure, prevent cataracts, improve your eyesight, fight your wrinkles, and so much more.Caronsine does in fact survive the digestion process because the enzymes that break down peptides don't act on dipeptides. They break down larger and larger proteins into smaller peptides that are absorbed into your body.I have resveratrol from a Japanese knotweed. I heard some supplement manufacturer emphasized that theirs is not from knotweed. Does this mean knotweed is inferior?No, resveratrol is a compound found in natural plants as well as in tons of dietary sources.If you're wondering about the label, don't hesitate to call the manufacturing company and ask for their certificate of analysis. If a person on the other line is hesitant or doesn't know what that is, you probably should consider using a different brand.How do I ascertain if a supplement will adversely impact my pharmaceutical medications?There are very few dangerous interactions between drugs and supplements. However, to be on the safe side, you might want to check Drugs.com.If you have a health question or concern, Dr. Mike encourages you to write him at askdrmikesmith@radiomd.com or call in, toll-free, to the LIVE radio show (1.844.305.7800) so he can provide you with support and helpful advice.
