How does melatonin affect the body?
Melatonin helps the body regulate the cycle of being asleep and awake. When more light is present, melatonin levels decrease signaling to the brain that it is time to prepare to be awake. In contrast, when less light is present the inverse takes place with an increase in melatonin signaling to the brain that it is time to prepare for sleep.
Where & how is melatonin made in the body?
While many tissues in the body produce melatonin the main producer is the pineal gland in the brain. This process takes place as melatonin is synthesized from serotonin which is preceded by serotonin’s synthesis from tryptophan hydroxylase.
