When considering complementary or alternative treatments, be open-minded yet skeptical. Keep in mind that supplements are not regulated, and learn about the potential benefits and risks. Here is an article from Mayo Clinic that might interest you about evaluating claims made by the producers and/or sellers of supplements, natural products and other alternative medicines. http://mayocl.in/2tGC0Jp

Quercetin is getting a lot of attention these days for its potential benefit. When evaluating the information be sure to note whether the evidence is based on test tube and animal trials or whether there have been human trials. Many drugs show promise in early trial phases but do not prove effective in later human trials. In the case of quercetin, more human research is needed. See this article and related research:

You might also be interested to know that Mayo Clinic is researching a drug called a senolytic – dasatinib plus quercetin - that has just moved into early human research.
“We are studying the effectiveness of this and other senolytic drugs, but that does not mean that these should be used by patients or prescribed by physicians for any off-label conditions,” says Dr. Kirkland. “I want to emphasize that no one should take these drugs. This research is only beginning.”

As always, please consult with your medical provider before taking supplements.
