What is serotonin used for?

Serotonin is not just a fancy word to impress your friends at dinner parties. It is actually an incredibly important neurotransmitter, involved in everything from mood regulation to digestion. In this article, we’ll dive deep into the world of serotonin and explore what it’s used for!

Getting to Know Serotonin

Before we can fully understand what serotonin is used for, let’s take a moment to get to know this fascinating little molecule.

What Is Serotonin?

Serotonin, also known as 5-hydroxytryptamine (or 5-HT for short), is a neurotransmitter that plays many roles within the body. It’s synthesized from the amino acid tryptophan, which can be found in foods such as eggs, turkey, and dairy products.

How Does Serotonin Work?

When neurons in the brain release serotonin, it binds to specific receptors on other neurons or cells throughout the body. This binding process then triggers various responses depending on where those receptors are located.

The Role of Reuptake

After being released by one neuron and sending its signal to another cell, most of the serotonin molecules will be reabsorbed back into their originating cell through a process called reuptake. However,some antidepressant medications work by blocking this reuptake process, allowing more serotonin to remain active between cells and potentially ease symptoms of depression.

The Physical Effects of Serotonin

Serotonin isn’t all about making you happy – although that certainly helps too! In fact,serotonin has numerous physical effects, some even more significant than its psychological ones.

Digestion

Did you know that about 95% of your body’s total supply of serotonin exists outside your nervous system? That means it has other functions beyond just sending signals between nerve cells! One major place where serotonin is found is the digestive system, where it plays a key role in regulating gut motility and other important processes.

Blood Clotting

Serotonin also acts as a vasoconstrictor – that is, it makes your blood vessels narrower. While too much of this narrowing can be problematic,the right amount actually helps to reduce bleeding by promoting clot formation at sites of injury.

Bone Density

Recent studies have suggested that serotonin may play an unexpected role in bone density regulation. In fact, mice bred without the ability to synthesize serotonin developed thinner bones compared with their normal counterparts!

The Psychological Effects of Serotonin

Of course, we can’t talk about what serotonin is used for without mentioning its crucial psychological effects.

Mood Regulation

Perhaps most well-known among these effects is its impact on mood regulation; low levels of serotonin are associated with depression , while increases in available serotonin are thought to improve symptoms such as hopelessness and sadness.

Anxiety Reduction

Serotonin appears to help calm anxiety by reducing activity in various parts of the brain involved in panic responses or fight-or-flight reactions. This calming effect explains why some types of antidepressants that raise serotonin levels have proven helpful for treating anxiety disorders like generalized anxiety disorder (GAD) and obsessive-compulsive disorder (OCD).

How Can You Boost Your Serotonin Levels?

So now you might be wondering: how can I get more happy neurotransmitters flowing through my system?

Eating Right

One way to naturally increase your body’s level of tryptophan,serotonin’s precursor amino acid, and thus hopefully bump up your available 5-HT supply is by eating foods rich in tryptophan such as cheese or nuts.

Foods high in tryptophan:
- Cheese --> Swiss
- Nuts --> Walnuts

However, since very little dietary tryptophan actually makes it to the brain (where serotonin is synthesized and used), there are other approaches to consider as well.

Exercise

Many forms of exercise, particularly cardio, have been linked with increases in serotonin levels. So if you’re feeling down and sluggish, acing up your sneakers for a little jog just might help lift your spirits!

Conclusion: The Many Roles of Serotonin

Overall, it’s clear that serotonin isn’t just one thing or used for one purpose – this neurotransmitter plays many essential roles throughout the body! So whether you’ve got tummy troubles or are feeling blue,serotonin may be able to lend you a helping hand. Just don’t forget to thank him properly next time he does!
