Over the years melatonin has become a common sleep aid supplement because of its relative safety and short term effects.

Unfortunately new research is highlighting just how short-lived the effect of long-term melatonin supplements can be, with a March 2018 paper stating, “Sleep quality of both discontinued and persistent melatonin users not deviate from controls.”

Not only does melatonin supplementation’s effects wear off over time, but it also adversely affects the pineal gland and other organs as it is a “hormone” that is negatively affecting the body’s internal operations.

Tryptophan differs from direct melatonin supplementation in that Tryptophan is the raw material that the body needs to produce melatonin. Therefore it’s typically better to focus on the nutritional supplementation aspect than on direct hormonal supplementation.
