According to the February 2008 edition of the "Journal of Vascular Health and Risk Management," bitter leaf can reduce bad and total cholesterol. In an animal model, supplementation with bitter leaf extract reduced LDL cholesterol by 50 percent while also boosting "good" HDL cholesterol. However, no research investigating bitter leaf on cholesterol has been conducted on humans.

Bitter leaf is an abundant source of the polyunsaturated fatty acids linoleic and linolenic acid. Because your body can't make these two fats, they are required from the diet. A study found in the November 2001 issue of the "American Journal of Clinical Nutrition" found that diets rich in these two fatty acids were protective against cardiovascular disease. In this study, those who consumed the greatest amounts of linoleic and linolenic fatty acids had a 40 percent lower risk of cardiovascular disease when compared to those that seldom consumed these two fats.
