Melatonin Research: Increased Lifespan
in Experimental Animals

Although much further investigation is required, it can definitely be stated that melatonin prolongs the lifespan of experimental animals. Much of the available information in this regard was presented by Dr. W. Pierpaoli in his book The Miracle of Melatonin, published by Simon and Schuster.

In one typical experiment, median survival of control animals was 23,8 months compared to 28,1 months in the melatonin-treated animals. This reflects a significant increase in lifespan of 18% which, in human terms, means an increase of nearly 13 years in life expectancy. In this experiment, melatonin was given nightly to the experimental group.
