Not all probiotics support the gut-brain connection. Only select strains, like L. plantarum PS128, are classified as psychobiotics.


These unique probiotics are scientifically researched and clinically proven to support brain function, mental clarity, and emotional balance.


Found in our supplements, they offer a targeted approach to enhancing mental health through the gut-brain axis.
 

Did You Know?

A clinical trial on patients with major depressive disorder found that L. plantarum PS128, a key ingredient in Reviest®, significantly improved depression symptoms after just 8 weeks of use. 


But how does it work? This powerful strain helps modulate the gut microbiota and reduce inflammation, which plays a critical role in brain function and mood regulation.

One study showed that PS128 can influence serotonin levels in the gut, where most of the body’s serotonin is made. This can help regulate mood and behavior.


Another study on rodents found that PS128 also affects dopamine levels, which are important for mood, movement, and overall mental health.


These findings point to PS128's potential as a psychobiotic, influencing both serotonin and dopamine levels, which offers therapeutic benefits for conditions such as depression, anxiety, and sleep disturbances

Frequently Asked Question

Ever Wonder How Gut Health Impacts Your Mood and Mind?

Your gut is often called your “second brain” because it directly affects mental well-being. An imbalance in gut bacteria can lead to stress, mood swings, and cognitive fog.


At Reviestlife , we use scientifically-backed probiotics like PS128 to support the gut-brain axis. Our formulas are meticulously crafted to restore balance, reduce stress, and enhance mental clarity. Trusted by experts, our products are made with the highest quality, so you can feel confident in the results.

What Are Probiotics Anyway and Why Are They Important?

Probiotics are live microorganisms that support gut health by balancing good and bad bacteria. They play a crucial role in digestion and are connected to mental well-being via the gut-brain axis.

 
They’re commonly found in foods like yogurt and supplements. These tiny helpers are not just good for digestion – they also influence mental well-being through the gut-brain axis, helping to manage mood, stress, and cognitive function.

What is the Gut-Brain Axis or Simply, the Gut-Brain Connection?

In simple terms, the gut-brain axis is a communication network between your gut and brain. Through nerves, hormones, and biochemical signals, they constantly share information, affecting mood, stress, and cognitive function.


This means that gut health has a direct impact on mental well-being, and vice versa. By maintaining a scientifically proven balance in the gut using probiotics, you can support both your digestive and mental health for overall improved well-being.
