Melatonin 3 mg 60 capsules
Melatonin is an important neurohormone found in humans and many organisms. It was isolated from the bovine pineal gland in 1958.

In addition to the pineal gland, Melatonin can also be synthesized in the liver, kidneys, gastrointestinal tract, adrenal glands, heart, gonads, uterus, platelets, leukocytes, natural killer cells, and other immune system cells.

While 80% of the melatonin circulating in the human body is synthesized in the pineal gland, The amount of melatonin that is made in other organs is very low. So it does not significantly contribute to blood circulation.
