Melatonin Supplements May Help With Cholesterol Levels

High cholesterol is a risk factor for cardiovascular disease. A recent study suggests that regular melatonin supplementation may help lower cholesterol levels.


Researchers from Shiraz University of Medical Sciences in Iran examined eight studies that were published between 1997 and 2014. The studies included participants between the ages of 16 and 74 from Iran, Poland, the United States, Brazil, and Mexico. One study had only male participants, while the others had both male and female participants.


After examining the data, the researchers found that a noticeable reduction of very low-density lipoprotein (VLDL) cholesterol occurred after melatonin supplementation. Additionally, they found a decrease in triglycerides in participants who took 8 mg of melatonin daily for eight weeks. They also noted a decrease in total cholesterol in people whose total cholesterol baseline evels were 200mg/dL who took 8mg per day of melatonin.


There were also improvements in LDL and HDL cholesterol levels, but they were not significant.


The study was published online ahead of print on November 16, 2017, in Clinical Nutrition.


Melatonin is a hormone that exists naturally in the human body. Previous studies suggest that it may help with sleep, and it is also used for other ailments, although with limited research to support those benefits. Melatonin can be taken in supplement form.
