Precursor to serotonin: what it is and what role it plays

The medical definition of serotonin says that it is a chemical produced by nerve cells. It is mostly found in our digestive system. The ‘happy hormone’ is made from tryptophan, an essential amino acid which we find in different foods.

Maintaining a healthy level of serotonin in your body impacts not only your moods, but also other aspects such as sleep, blood clotting, and bone health. We will discuss each element.


As we’ve mentioned before, serotonin is responsible for regulating your moods. Low levels have been linked to anxiety and depression, while high levels can reduce your libido and decrease arousal.

Normal levels help you remain emotionally stable, focused on what you have to do, calm and happy.
