Quorum Sensing: What is your gut telling you?

Mar 27, 2024

Quorum sensing (QS) plays a fascinating role in human gut health, acting as a communication system for the trillions of bacteria residing in our gut. Here's a breakdown of its significance and how you can apply this information to building a happier gut.


What is Quorum Sensing?

Imagine a community of bacteria in your gut. QS allows them to communicate with each other using chemical signals. As the bacterial population grows, the concentration of these signals increases. Once a certain threshold is reached, the bacteria sense they're at a high enough density and can collectively activate specific genes, influencing their behavior.

Impact on Gut Health

As you can imagine, QS is crucial for maintaining a healthy gut microbiome. This communication system regulates a variety of bacterial functions:

Feeding a crowd - Bacteria can use QS to coordinate the breakdown of complex carbohydrates for shared benefit.


Community protection - Some bacteria use QS to build protective communities called biofilms. Biofilms can be beneficial or detrimental depending on the bacterial species.


Competition and cooperation - QS allows bacteria to acquire resources more easily if there is competition for them from rival colonies. Bacteria may also cooperate in beneficial activities like waste removal.


Potential for Therapeutic Intervention

Currently, researchers are beginning to explore the potential of manipulating QS for therapeutic purposes. Early results show that by influencing bacterial communication, we might be able to reduce the growth of harmful pathogens. Disrupting their communication could limit their ability to cause infections or colonize the gut.


We may also be able to promote the growth of beneficial bacteria through this method. Certain probiotic strains might then be chosen for their ability to positively influence the gut microbiome through QS.


While promising, this field is still in its early stages. Accurately mimicking the complex gut environment for research and developing specific, safe interventions for tapping into QS manipulation still poses significant challenges. However, understanding QS offers exciting possibilities for promoting gut health and potentially treating various gut-related disorders. Further research is needed to fully map its potential.


Consider supplementing with the following proven beneficial bacteria for gut health:

Lactobacilli bacteria are well-known for their ability to produce lactic acid, which aids digestion and inhibits the growth of harmful bacteria. Some studies suggest specific strains like Lactobacillus plantarum and Lactobacillus casei might utilize QS to influence the gut environment positively.1


• Bifidobacteria contribute to gut health by breaking down complex carbohydrates and producing beneficial short-chain fatty acids. Certain Bifidobacteria strains, like Bifidobacterium longum, might also play a role in gut immune function through QS mechanisms.1

Also, consider incorporating prebiotic rich foods or supplements. Prebiotics are non-digestible fibers that serve as food for beneficial gut bacteria. Prebiotics like inulin and fructooligosaccharides (FOS) have been shown to promote the growth of specific gut bacteria, including those involved in beneficial QS interactions. However, the specific mechanisms of how prebiotics influence QS are still being studied.1


Remember that research on dietary support for manipulating specific QS pathways to gut health is still evolving. Consulting your healthcare provider regarding specific dietary recommendations for your unique gut health needs is always recommended.

Chronic and excessive stress can build over time and become harder for our bodies to adapt and cope. While men and women share many of the same stresses, studies show that women are more affected by high levels of stress than men. The most common symptoms of stress women experience are fatigue, irritability, sleep issues, lack of motivation, digestive challenges and nervousness. In addition, there are life experiences unique to women that bring their own set of stresses – namely pregnancy and motherhood.

The scientific evidence is in—we all need Omega-3s. That's why they're called essential fatty acids. And, while there's no doubt that Omega-3s are critical for staying healthy, they cannot be made in the body. You must get them from your diet or supplements, but should you take flax oil or fish oil to get what you need?

When we talk about healthy aging for women, conversations tend to focus on menopause, hormones, and breast and bone health. While these are all important topics regarding women and aging, we can’t forget to look at some other crucial areas regarding a woman’s overall health and longevity. Heart health in particular is an important–but often sidelined–topic when it comes to women’s health.* While it can seem like we have no control over how well we age, there are vital steps a woman can take to do her best to ensure heart health throughout her lifetime. Focusing on a healthy diet and consistent exercise, while also managing mental and emotional well-being, are critical to maintaining heart health. There are also powerful supplements that women can incorporate into their daily health routines to support cardiovascular wellness and overall healthy aging.* Olive Extract EP20™ for Overall Healthy Aging* Nothing says healthy aging quite like the Mediterranean diet, full of lean proteins, healthy fats, and antioxidant-rich dietary staples. If you’re looking for a way to reap some of the benefits of the Mediterranean diet yourself, try Olive Extract EP20. This exciting new formula supports an array of healthy aging benefits, including immune function, balanced cholesterol levels, and overall cardiovascular health.*† The monounsaturated and polyunsaturated fats in olives and olive oils provide many health benefits, but those aren’t the only healthy components that make up these healthy foods. Polyphenols and other compounds in olive fruits and leaves (including oleanolic acid, oleuropein, hydroxytyrosol, and alpha tocopherol) support healthy aging, cognitive function, and the cardiovascular system, plus protect against the risk of oxidative stress. Because Olive Extract EP20 delivers a full spectrum of olive fruit and leaf compounds in one concentrated supplement, it provides a convenient, consistent source of these nutrients daily.* Aronia Berry Complex™ for a Strong Heart* Another simple way to support heart health as you age is with Aronia Berry Complex. This product combines Aronia Berry Extract AB40™ with French Grape Seed Extract VX1® to deliver powerful antioxidant protection and support virtually every aspect of cardiovascular health.* Aronia berries by themselves have an incredible antioxidant ORAC value, outshining the benefits of many other berries, including strawberries, blueberries, and cranberries. But they also have a tart taste that many people don’t enjoy. In order to make aronia berries palatable, they’d need to be blended with a high quantity of sugar, which would diminish any health gains from the botanical. Additionally, with berries, your intake of compounds would vary greatly depending on when and where the berries were harvested. That’s why an aronia extract standardized for 40 percent polyphenols–like Aronia Berry Extract AB40–is a better choice. It provides a consistent level of beneficial compounds in a convenient form. The other ingredient in Aronia Berry Complex–French Grape Seed Extract VX1–features powerful health-promoting nutrients called oligomeric proanthocyanidins (OPCs) that support a wide range of health needs for women. These OPCs are small and easily absorbable, allowing them to deliver maximum benefits. Taken on a daily basis, this supplement supports weight management††, cholesterol balance†, focus and concentration, blood pressure health†, cellular protection^, and healthy immune function.*

I discovered Pranic Healing by chance, more than nine years ago in Brazil, where I’m originally from. As a successful software engineer for more than two decades, I had always been very skeptical about anything that was not palpable or fully endorsed by western science. After stumbling upon an article featuring a Harvard study on the benefits of meditation, I decided I had to give it a try. So, I reached out to this genius childhood friend of mine who simply told me to take a Pranic Healing Level 1 class, and my journey began. I registered without thinking and barely read what the class was about, so I had no idea what to expect of this weekend long work-shop. Perhaps some new age, handholding, “let’s get together and feel all right” kind of thing? It couldn’t be farther from that! In a Pranic Healing class the human energy anatomy is taught very methodically and with a high level of detail. We learn about the 11 major chakras (energy centers), their physical and psychological functions, plus practical and powerful no-touch hand movements to remove energy blockages and improve the quality of the energy flowing through a person’s body. Ultimately, a Pranic Healing session can lead to an accelerated rate of self-healing, substantially improving the quality of one’s health, both physically and emotionally. As cool as this may sound, my engineer’s mind instantly rejected it all. I even considered not returning for the second day of class, but there was something inside telling me to “finish what I had started”. Besides, on the second day we would learn the Meditation on Twin Hearts, my main goal from the very beginning.
