Probiotics and Serotonin production have been linked for some time now. Recently, scientists have identified specific probiotics that increase serotonin production. Before introducing our list of the best probiotics for serotonin production, we wanted to give you an overview of the science.
Once again, keep in mind that we aim to provide unbiased information and advice. This website is based on our enthusiasm for these products’ potential. We welcome feedback from our readers and will continue to update it based on that information, our own experience, and emerging research.
What is Serotonin?
Serotonin is a neurotransmitter, a chemical that helps transmit signals in the brain. It is widely known for its role in regulating mood but has various other important functions. Here are some key points:
1. Mood Regulation: This neurotransmitter is often referred to as the “feel-good” chemical because it contributes to feelings of well-being and happiness. Imbalances in levels are associated with mood disorders such as depression and anxiety.
2. Sleep: It also regulates sleep patterns by controlling the sleep-wake cycle and is a precursor to melatonin, a hormone that regulates sleep.
3. Appetite: This neurotransmitter helps regulate appetite and digestion. It is found in the gastrointestinal tract and helps control bowel movements and function.
4. Memory and Learning: It plays a role in cognitive functions, including memory and learning.
This neurotransmitter is synthesized from the amino acid tryptophan and is primarily found in the brain, bowels, and blood platelets. The balance of levels is crucial for maintaining mental and physical health, and signaling disruptions can significantly affect mood, sleep, and other physiological processes.
Probiotics and Serotonin, the Basics
Probiotics, which are live microorganisms that confer health benefits when consumed in adequate amounts, have been linked to various aspects of human health, including digestive health, immune function, and mental health. One area of interest is their potential role in influencing neurotransmitter levels. Serotonin is a neurotransmitter primarily found in the gastrointestinal tract, where it plays a crucial role in regulating mood, appetite, and sleep. Research suggests that the gut microbiota, the community of microorganisms in the digestive system, may interact with this system. An increasing amount of evidence suggests that probiotics may play a role in the probiotics and serotonin system.
Best Probiotics for Serotonin Production
Identifying the “best” probiotics for serotonin production is challenging because research in this area is ongoing, and individual responses to mood probiotics can vary. However, certain strains have shown promise in influencing levels indirectly through their effects on gut microbiota and related pathways. What follows are some probiotics that increase serotonin that have been studied.
Research Review
Lactobacillus rhamnosus: This may be one of the best probiotics for serotonin production, given that it has been extensively researched for its effects on mood and anxiety. Animal studies have shown that Lactobacillus rhamnosus can increase levels in the brain and reduce anxiety-like behaviors. However, more research is needed to understand its specific mechanisms of action in humans.

Bifidobacterium infantis: Known for its ability to support gut health, Bifidobacterium infantis has also been studied for its potential effects on mood. Some research suggests that it may help reduce symptoms of depression and anxiety, possibly by modulating the gut-brain axis and serotonin levels. This strain shows up on most lists of probiotics that increase serotonin production.

Lactobacillus helveticus: This probiotic strain has been investigated for its anxiolytic (anti-anxiety) effects. Studies have shown that Lactobacillus helveticus supplementation can reduce anxiety-like behaviors in animal models, possibly by modulating neurotransmitter levels.

Bifidobacterium longum: Another one of the best probiotics for serotonin production, this strain also belongs to the Bifidobacterium genus, Bifidobacterium longum, has shown promise in preclinical studies for its potential to modulate serotonin levels and improve mood-related behaviors. It may exert its effects through various mechanisms, including immune modulation and gut barrier function.

Lactobacillus plantarum: Research suggests that Lactobacillus plantarum may have antidepressant-like effects in animal models. While the exact mechanisms are not fully understood, they’re thought to involve modulation of inflammation, neurotransmitter levels, and gut barrier function. This makes it potentially one of the best probiotics for serotonin production.

When selecting a probiotic supplement, it’s essential to consider the specific strains, dosage, formulation, and any additional ingredients. Additionally, individual responses can vary, so what works well for one person may not have the same effects for another. It’s advisable to consult with a healthcare professional before starting any probiotic regimen, especially if you have specific health concerns or conditions.
Studies About Probiotics that Increase Serotonin
Several studies have demonstrated a connection between probiotics and serotonin production: 
Regulation of Tryptophan Metabolism: Tryptophan is an amino acid precursor to serotonin. Some strains of gut bacteria can metabolize tryptophan, influencing the availability of this precursor for synthesis. Probiotics may modulate the gut microbiota in a way that affects tryptophan metabolism.
Gut-Brain Axis Communication: The gut-brain axis is a bidirectional communication network linking the gut and the central nervous system. Probiotics can influence this axis, potentially affecting production and signaling. By modulating gut microbiota composition, probiotics may indirectly influence serotonin levels and related mood regulation.
Inflammation and Immune Function: Dysbiosis, an imbalance in gut microbiota composition, has been linked to inflammation and altered levels of neurotransmitters. Probiotics have anti-inflammatory properties and can help restore gut microbial balance, which may, in turn, impact levels.
Animal Studies: Some animal studies have shown that certain probiotic strains can increase serotonin levels in the gut, leading to changes in behavior indicative of improved mood and reduced anxiety.
Probiotics and Serotonin, Cautions
While the evidence supporting the link between probiotics and serotonin is promising, more research is needed to fully understand the mechanisms involved and determine the specific strains, doses, and formulations that may be the best probiotics for serotonin production and improving human mental health outcomes. For now, it does appear quite promising that there are probiotics that increase serotonin production.
Summary and Our Work
It’s essential to note that while the link between probiotics and serotonin appears quite likely, and thus, probiotics that increase serotonin production can complement traditional treatments for mood disorders, they should not be considered a substitute for professional medical advice or treatment. If you’re considering using mood probiotics to improve mood or mental health, it’s best to consult with a healthcare provider to develop an appropriate plan tailored to your individual needs. This is particularly true if you are on any prescription medications or have sensitivities or allergies.
