Serotonin

Most people have heard of the neurotransmitter serotonin. It is known as the “feel good” chemical. Serotonin causes the good feeling you get after you see a picture of a cute dog, or receive a gift. But serotonin doesn't just affect your brain and emotions. It affects almost every major system in the body.

To start, about 95% of your body’s serotonin is manufactured in your intestines. As a result of this, the saying ‘You are what you eat!’ becomes even more important. If you have a healthy diet that includes whole foods like fruits, vegetables, and lean meat, your body has an easier time making and processing serotonin. But if you have a bad diet that includes lots of processed foods, your serotonin levels will be hindered, making you feel worse.

Serotonin also modulates cardiac function. Serotonin receptor expression increases in failing cardiac ventricles. Studies suggest that serotonin antagonists may help improve cardiac function. 

Overall, Serotonin is a very versatile chemical, that does more than you may think. Not much is known about serotonin, since it was discovered just 50 years ago, but more research is being done everyday.
