Low serotonin levels can cause changes in your mental health, such as sadness, depression, irritability, trouble sleeping, and aggression

Serotonin is a neurotransmitter that is mostly known for being a hormone that balances your moods, but it’s also responsible for the following. Serotonin:

  • Is a neurotransmitter that regulates the intensity of the signals your neurons emit.
  • Regulates gastrointestinal function.
  • Helps you form blood clots.
  • Stimulates the part of your brain that causes you to vomit if you consume something that’s toxic or an irritant.
  • Regulates the calcium levels in your bones.
  • Maintains the quality of your dreams
  • Adjusts your libido and sexual function.

Because serotonin is involved in a variety of processes in the human body, there are lots of different symptoms when your levels are low.

Serotonin isn’t just associated with digestive processes: in fact, 95% of it is found in your intestines.

When you have low levels of serotonin, it’s common to suffer from constant mood swings, as well.
