Hello! and welcome to Wikipedia. The number of ads on a page is often a sign of bad sources but that is not always the case. Have a look at WP:MEDRS for a good guide on preferred sources on WP:MEDICINE articles. In my opinion the linked article is not a high quality source because it offers advice rather than scientific health information suitable for an encyclopedia. Try going through the list of references at the end of said article and see if it leads to some good sources. Wafflephile (talk) 18:14, 8 March 2013 (UTC)[reply]
