Probiotics and the Gut-Brain Connection

July 18, 2022

It’s amazing that there is still so much we are discovering about health, nutrition, and the human mind even today. One such area we are learning more about is the Gut-Brain Axis.

The gut-brain axis is simply your gut and brain communicating back and forth through the enteric nervous system. Because of this communication, the billions of microorganisms that inhabit the digestive tract, called the gut microbiota, can influence various normal mental processes and phenomena and is involved with mental and neurological health.

Recently, it has become well established that the gut microbiome influences development and physiology, playing a key role in the balance of health. Emerging evidence has also suggested a role of the gut microbiota in brain function and behavior as well as playing an integral part in regulating the enteric nervous system, endocrine system, and the immune system.

Over the last few centuries, the gut microbiota has experienced tremendous change from the modern transformations in diet, lifestyle, medical care, pesticides, processed foods, additives, and so on. Part of the struggle with maintaining a healthy gut arises when we don’t have a healthy diet and develop picky eating habits. So what can you do to help balance the gut in situations like these?

Probiotics, but not just any probiotics!

It's been shown that targeting specific species within the microbiota can support mental health. Certain probiotic strains have been shown to increase the levels of dopamine (supports focus), serotonin, and brain-derived neurotropic factor or BDNF (supports mood).

Our new products, MicroVita® Focus and MicroVita® Mood, include these helpful strains to support focus, mood, and overall healthy gut wellbeing. We partnered with Dr. Jennifer Kozek, the author of Healing Without Hurting in formulating the MicroVita® probiotics.

Jennifer Kozek is the author of Healing Without Hurting and a board-certified psychotherapist. She has a Masters of Science in Counseling, and is certified in integrative medicine for mental health and she have extensive experience in private practice.

MicroVita® Focus includes six probiotic strains that have been clinically shown to support focus, attention, and cognition. It contains PS128® (Lactobacillus plantarum), which has been clinically shown to support attention and reduce hyperactivity. Three studies of PS128 with autistic children and adolescents indicate it can improve neurological symptoms in some patients.

MicroVita® Mood has six probiotic strains that have been clinically shown to support mood, reduce stress, and diminish anxiety. It contains Lactobacillus helveticus (Rosell-52)*, which has been shown to decrease anxiety and depression. Another study showed that individuals that supplemented Rosell-52 showed significant improvement in sleep quality, mood score, and the ability to feel pleasure.

So if you're looking to support your gut and mental health, be sure to try our new MicroVita® probiotics—coming August 2022!
