Wang MY, Peng L, Weidenbacher-Hoper V, Deng S, Anderson G, West BJ.

132 heavy smokers completed a one-month, randomized, double blind, placebo-controlled clinical trial designed to investigate the effect of Tahitian Noni Juice on blood lipids. Drinking 1 to 6 fluid ounces per day significantly reduced cholesterol levels, triglycerides, and hs-CRP. Decreases in LDL and homocysteine, as well increases in HDL, also occurred in noni juice drinkers. (original abstract available at http://www.hindawi.com/journals/tswj/2012/594657/).
