Herbal Extract Significantly Extends The Lifespan Of Fruit Flies

June 18, 2013: 12:00 AM EST
A study in fruit flies has found that an extract of the plant Rhodiola rosea increases the lifespan of the flies beyond the increase gained by calorie restriction. It had already been shown that fruit flies live longer when the amount of yeast they consume is decreased. When the flies are also fed the herbal extract they lived about 24 percent longer. The extract also delayed the loss of physical performance as the flies aged and even extended the lives of old flies. The researchers said they are not claiming that Rhodiola supplements will enable humans to live longer. Their discovery is increasing the understanding of how supplements that purportedly promote longevity actually work in the body.
