When I think of serotonin, I picture happiness.

Big Pharma has successfully marketed serotonin as our joyful neurotransmitter. With it, thoughts of happiness, love and enjoyment are profound. Therefore, we can piece together what happens when serotonin is low, but what happens if we have too much?

Serotonin Syndrome has been influencing researchers in recent times. High levels are most often caused by serotonergic pharmaceutical drugs, supplements, and certain illicit drugs. There’s also the chance your neurotransmitter profile is geared toward serotonin dominance.

When your brain is swamped with serotonin, aggressiveness is a very common symptom. This may sound counterintuitive, but an illustrative example is when illicit drug users ‘rage out’, often depicted via media sources.

Dilated pupils are a good indication that you have elevated levels of serotonin, as the muscle groups in the iris become activated. In fact, our body’s ability to find deep sleep comes from our pupils dilating to amber light (think campfire) and initiating not only serotonin production, but also melatonin. This is why your eyes dilate when illicit drugs are used. It’s no surprise that high levels of serotonin cause fatigue, making the person feel very sleepy and drowsy.

High serotonin has also been linked to high blood pressure and hypertension, and since serotonin plays a role in temperature regulation, some people may have hot and cold flushes, which can lead to constant shivering.

Though the biggest issue with elevated serotonin is its ability to cause mania. This has been directly linked to long-term use of SSRI’s, and is often confused with clinical diagnoses of other mental health conditions such as bipolar disorder.

Serotonin is present in our brain (10%) but mostly within our digestive system (90%). One of its main roles is peristalsis, the movement of our gut. When levels become too high, diarrhoea and vomiting are common side effects.

But there’s hope, and some ways to lower Serotonin can be quite simple.

  • Dietary intervention: Try lowering food groups that contain tryptophan (amino acid that initiates serotonin production). Carbohydrates help with the uptake of this amino acid, so a high fat and protein diet would be a good place to start.
  • BCAA’s (Branch Chain Amino Acids): Have been found to effectively inhibit tryptophan absorption.
