The short answer is NO - as in TMNO: Phen375 contains L-Carnitine which has been linked to heart disease. An article published online April 7, 2013 in Nature Medicine - http://www.nature.com/nm/journal/vaop/ncurrent/full/nm.3145.html
- discusses concerns that intestinal metabolism of substances like choline and phosphatidylcholine produce trimethylamine, and that is metabolised to trimethylamine-N-oxide - (TMNO) a substance that is known to accelerate atherosclerosis. dietary L-carnitine, such is found in supplements like phen375 and red meat also produce TMNO.
Plasma L-carnitine levels in subjects undergoing cardiac workups are predictive of cardiovascular disease in patinets who have ligh levels of TMAO.
Omnivores produce more TMNO than vegans or gegetarians.
