Health experts are seriously studying the possibility of the natural sleep-enhancing food supplement melatonin’s potential benefit in extending the lifespan.
In test-tube and animal experiments, researchers have found that melatonin protects cells, strengthens the immune system, slows the growth of some tumors, and protects the heart and blood vessels.
Tests with laboratory mice suggest that melatonin might also reduce the effects of aging and enhance sexual function, but scientists caution that these results are very preliminary and still not conclusive.
Experts agree though that the preliminary findings are exciting and promising.
Regarding the question if melatonin can extend lifespan, in tests on both rats and mice, melatonin caused a significant 20 percent increase in their lifespan.
