References & Sources

Please verify every citation yourself. We list real publications and public-agency pages that relate to the ingredients and topics discussed on this site, but links and page addresses change, and a study on an ingredient does not mean the same result applies to the CitrusBurn capsule. Open each link, check that the title, authors and journal match, and read the original source before relying on it.

Numbers in square brackets on our review point to the entries below. Note that these sources concern individual ingredients or general topics. We did not find a published clinical trial of the finished CitrusBurn formula, so none is listed.

A note on berberine

We discuss berberine on the review page in general terms only (studied mainly for blood sugar and metabolic markers, with possible medication interactions). If you want to read more, search a current medical database such as PubMed or the NIH websites for recent systematic reviews on berberine, and discuss it with a pharmacist.
