One controversial study shows that gut health is more important than we think...

Can improving gut health really improve cogntive function and our response to stress?

I'm about to blow your mind...

This is going to be a bit controversial but it has some really important lessons. You may have heard the fact that bacteria and probiotics are the essence of life. Without them, you would die pretty early in life. Here's what I mean.

The body is made up of approximately 10 trillion human cells and 100 trillion bacterial cells. So technically in that capacity, you are 90% bacteria. There are actually more bacterial cells in your body than there are stars in our galaxy. 

With that in mind, you can probably understand why having healthy bacterial flora is extremely important for your overall longevity

I want to show you a controversial study that I learned about while studying neuroscience at Duke. It was done by a neuroscientist named John Cryan of University College Cork in Ireland.

He was curious to test the stress response of mice when put into certain situations when fed a certain bacteria. So he took two groups of mice. The first group was fed a probiotic strain known as lactobacillus rhamnosus. The second group, which was his control group, didn’t receive any probiotic strains.

Cryan hypothesized that the lactobacillus rhamnosus would help with a stress response.

He threw both groups into buckets of water and measured their latency to give up. There was no way for either group to get out of the bucket.

The control group, who didn't have any probiotics, would give up. Their stress response was so high that they would swim around in circles and simply give up after four minutes. Cryan would pluck them out of the water before actually drowning. He didn't let them die.

On the other hand, the group that he fed the lactobacillus rhamnosus to would not stop swimming. They just would not give up. While the control group was ready to die at a certain point, the lactobacillus rhamnosus group simply did not give up. They would just keep on swimming.

Afterwards he measured the cortisol levels of both groups.

He found that the control group actually had 100 times higher cortisol levels than the group that was fed lactobacillus rhamnosus. The latter were the ones who didn't give up.

They were the ones who actually had such a low stress response that they had more energy and a will to live. Now this is where things get more controversial.

Cryan wanted to really test this theory that lactobacillus rhamnosus is what caused the drastically lower cortisol levels.

He severed the vagus nerve of the group of mice that took the lactobacillus rhamnosus then he replicated the same experiment. He threw both groups of mice back into the water. What happened next was that both groups acted the same. They gave up after minutes of swimming.

What this taught us is that there is communication between the gut and brain that lowers cortisol levels with this one strain of bacteria.

While this was done in mice, humans have the same body structures as these mice did and we have the same vagus nerve. We have the GABA receptors in our brain communicate with our gut with this strain of bacteria.

So it does point to the fact that humans may have a similar result.

You're probably wondering the same thing as I did the first time I saw these studies. Where can I get probiotics? What's the best way to get the right bacteria, specifically the strains of bacteria that are great for men? How can I implement this into my diet or supplement regime?

You can get these benefits from food.

... or from probiotic supplements.

One issue with this is a lot of people do not like to eat fermented foods due to their taste. Another option that you have is a product we formulated specifically for men called Floracil50 by UMZU.
