The relationship between sleep and the gut flora

Is it possible that getting a good night’s sleep depends on the gut? The answer is; yes.

Almost 20% of the world’s population suffer from sleep problems and spend their nights twisting and turning. And anyone who has stared sleeplessly at the ceiling, counting sheep, knows that this experience can be stressful and extremely frustrating. The next day can be a real pain, and poor sleep for an extended period of time can cause both illness and affect the memory. Research also shows that poor sleep affects the gut flora negatively, which can be problematic since this is where most of the immune system is located.

Irregular sleep routines

A study conducted at the Weizmann Institute of Science in Rehovot, Israel, examined what happens to the gut flora when sleep is irregular. The study focused on stool samples from lab mice and then also tested a small group of people who were jet lagged.

One thing that became apparent following the study conducted on mice was that the activity in the gut flora looked different during the day compared with at night. When the mice were awake and active, the bacteria in the gut flora were mainly involved in burning nutrients and repairing DNA. During the period of the day when the mice rested and slept, the intestinal bacteria instead transported away toxins and built up different parts of the gut flora. If, on the other hand, the mice suffered from a disrupted and irregular circadian rhythm, the same fluctuations and activities did not occur in the gut flora, which indicates that the circadian rhythm and sleep quality may have an effect on the composition and function of the gut flora.

“When the study’s test subjects returned to more regular sleeping habits, the concentration of unhealthy bacteria decreased again”

The part of the study that was performed on humans showed that the participants with jet lag had increased concentrations of the type of bacteria more common in individuals suffering from obesity and diabetes. These bacteria are also associated with weight gain, increased levels of blood glucose and a higher percentage of body fat. When the study’s test subjects returned to more regular sleeping habits, the concentrations of unhealthy bacteria dropped again and the balance in the gut flora stabilised.

The largest variety of intestinal bacteria

A study published in the American journal Plos One also showed that there may be a connection between the gut flora and our sleep. In the study, different values in the bodies of test subjects, relating to sleep quality, were monitored while they slept, using advanced measuring tools. The researchers then took samples of the test subjects gut flora, and were able to conclude that those test subjects who got the most qualitative sleep were also the ones who had the greatest variety of bacteria in their guts.

The gut flora and serotonin

You may know that melatonin is the sleep hormone that makes us tired. But in order for melatonin to be created, another hormone is required, namely; serotonin, and 95% of the serotonin in our bodies is produced in the gut – which is affected by sleep. Serotonin is often described as a “happiness hormone” and has a powerful effect on our mood and cognitive function and also plays an important role in regulating our sleep cycles. Keeping the intestines in good shape is therefore important for both mood, cognition and ultimately sleep.

Tips for improving sleep quality

So what can one do to ensure a good night’s sleep? Here are some tips to help you.

  • Exercising, fresh air, plenty of daylight and regular sleeping hours are some of the things that are said to promote sleep quality.
  • Putting down your mobile phone and avoiding coffee and tea are other examples of measures you can take to attract the Sandman.
  • Lying comfortably on your back in a safe environment and then focusing on your breathing is also said to be helpful.

A little bit of mindfulness, in other words. Since intestinal health also seems to have an effect on sleep, an anti-inflammatory and intestinal-friendly diet may be worth trying.

What our customers say


I started with Synbiotic15 only hoping to improve my gut health and was surprised my skin got better. It’s been a drastic improvement – my eczema on my back, arms and cheeks are almost gone. And I don’t get flare ups anymore. I also feel less bloated / uncomfortable. Am Super happy with it.

Synbiotic15 has been amazing, so much so, that it will now be a part of my daily routine no matter what.

Natalie Dau

Professional athlete, mum and media personality


I probably felt bloated 3-4 times a week and it was a big issue for me. Yet I couldn’t figure out what exactly triggered it or how to stop it. Taking Synbiotic15 makes me feel good. I can really feel the difference and I don’t get bloated. Which is huge for me! It gives me more confidence and more comfort.”

Claire Jedrek

Presenter, race driver and mum


Before taking synbiotic15, I suffered from a painful, bloated abdomen (as if 9 months pregnant). I visited several doctors, but the cause was unclear. A food intolerance test revealed so many nutrients to which I reacted badly, it was impossible to stick to. A friend suggested Synbiotic15. Her experience was convincing, so I tried, and with effect! I suffer significantly less from bloating. I was planning to try it once, but because of the super results I'm extending it. If you have gut problems, I can definitely recommend this.

As a nutritionist – when I recommend a supplement, it’s important that the quality is as close as possible to what you can get from nature. For me, Synbiotic15 fits those criteria. After clients started with Synbiotic15, one of the first things they noticed is improved digestion and more energy. The best way to start any health journey.

It’s such a big difference since taking Synbiotic15. My body feels good, my energy levels are high, and I somehow feel lighter. This is great, I feel awesome.

Paul Foster

Host, model, and actor


I tried Synbiotic15 for two months and it’s when you stop that you really feel the difference. The probiotics calm your internals and everything becomes more consistent; I think it helps the bloating too. It’s not an instant fix but a good addition to supplements for feeling better all round, and a help with IBS.

When you take care of your gut, you’ll get so much more energy. And while you don’t need a supplement – Synbiotic15 helps to kickstart your progress and supports the lifestyle changes you make.

I have many allergies which have a severe reaction to my bowel movements. By taking supersymbiotic my bowel movements are much smoother, very happy.
