How do they make melatonin
 

What is melatonin?
Melatonin is a hormone made by a part of the brain called the pineal (say: “pie-nee-all”) gland. Melatonin may help our bodies know when it’s time to go to sleep and when it’s time to wake up.

Melatonin supplements (in pill form) are also available. Two types of melatonin may be used in these pills: natural and synthetic (manmade). Natural melatonin is made from the pineal gland of animals. This form could be contaminated with a virus so it is not recommended. The synthetic form of melatonin does not carry this risk. If you are not sure if your melatonin is natural or synthetic, ask your doctor or pharmacist before taking it.
