Introducing lactobacillus reuteri

So as you might know there are many millions of bacteria living in the human gut, from as many as one thousand different species. Most of them are beneficial and even necessary to the normal functioning of our body. We call these good guys “probiotics”.
Now this whole excitement over the bacterium lactobocilus reuteri, which is usually abbreviated to l. reuteri, started when a team of researchers from various north American and European universities fed probiotic yogurt to mice during gastrointestinal studies.

Probiotic yogurt, as the name suggests, is yogurt that contains various probiotic bacteria. To their surprise, the researchers noticed substantial improvement in the appearance of the fur of the mice that were fed this yogurt. And this improvement was apparent in as little as 7 days. In contrast to the mice that got the probiotic yogurts, mice that were fed the standard laboratory dry food had dull fur and suffered from hair loss and dermatitis.

Now the obvious problem the researchers originally faced was that the probiotic yogurt contains, aside from probiotic bacteria, well, the yogurt itself. But after further experimentation the researchers were able to confirm that it was indeed the probiotic organisms and not the yogurt that was responsible for these effects. Listen to this guys: simply adding l. reuteri to the drinking water of the mice, led to the same effects on their fur that had been observed through eating the full yogurt. So this was the conclusive proof that the l. reuteri was responsible for all the fur improvements.

Now as a side note before we get onto the results of these studies, l. reuteri was first discovered in human bodies in the 1960. At that time it was present in about 30-40 of the human population. But due to the declining quality of our diet, its presence in the human population has now gone down to the point where it’s only found in 10-20% of the population. It’s usually passed on from mother to child via breastfeeding.

So let’s get back to exactly what the researchers found that this bacterium does in mice, and guys the list is impressive.

-Firstly, it leads to healthier skin by literally thickening the dermal layer.
-It also stimulates the growth and proliferation of sebocytes, which are the cells that secrete sebum in the scalp and other skin regions. More sebocytes translate into the secretion of more sebum, which leads to shinier fur.
-The lactobacillus reuteri also induces a more acidic pH, resulting in radiant skin and shiny hair.
-Finally, and most importantly, it stimulates hair follicles to enter the anagen or growth phase of the hair cycle. And in this particular respect the effects are dramatic. The researchers found that l. reuteri supplementation resulted in 74% anagen hairs, vs. 36% in the control mice that were fed the standard laboratory diet. More than doubling in the number of actively growing hairs. You can see this effect in action in this photograph:

All the mice in this photograph had been shaved on a patch of their back five days prior. But the mouse on the left had not received l. reuteri, whereas those on the right had. The difference in growth rate is astounding. Also notice how much more shiny, rich and healthy looking the newly grown hair is on the mice that were given the l.reuteri. This is what these researchers called the probiotic “glow of health”.
