Serotonin – the happy hormone

What is serotonin?

Serotonin is created by a biochemical conversion process that combines tryptophan with tryptophan hydroxylase. Serotonin is also a neurotransmitter, although some consider it to be a hormone.

Where is it produced?

Serotonin is produced in the intestines and the brain. It is also present in the blood platelets as well as the central nervous system (CNS).

Causes for low serotonin levels:

  • Prolonged periods of stress may deplete serotonin levels
  • Genetic factors, faulty metabolism, and digestive issues can impair absorption and breakdown of our food which can reduce the ability to build serotonin
  • Poor and unbalanced diet
  • Toxic substances like heavy metals, pesticides, pharmaceutical medicine use, and some prescription drugs can cause permanent damage to the nerve cells that make serotonin and also other neurotransmitters
  • Substances such as caffeine, alcohol, nicotine, NutraSweet, antidepressants, and some cholesterol lowering medications can deplete serotonin and other neurotransmitter levels
  • Hormone changes cause low levels of serotonin and neurotransmitter imbalances
  • The lack of sunlight contributes to low serotonin levels
