Rebuilding gut bacteria – when the gut flora is out of its natural balance

The gut is not only the longest but also the most underestimated organ in the human body. If it doesn't function properly, nutrient absorption is limited, which drains your energy and can even cause dangerous nutrient deficiencies in the long term. At the same time, the gut is the seat of the immune system. If you often get sick and experience constant digestive problems, it’s likely that your gut function is impaired.


At its core, the gut is nothing more than a permeable tissue tube. Everything hinges on the gut flora – the so-called microbiome. These are bacterial strains that support your body in fighting harmful pathogens and in nutrient absorption. However, the gut flora is delicate. Stress, medications, and an unbalanced diet can disrupt its balance. If you don’t actively support your body in rebuilding gut bacteria, it will have a hard time regenerating its gut flora.


How can I rebuild healthy gut bacteria?

The good news: You can help your body rebuild its gut bacteria. The bad news: This usually requires a lot of patience, as the good bacterial strains first need to resettle in your gut and then take time to grow back to their original size. The following three measures can help you rebuild healthy gut bacteria.


Gut cleansing – is it really necessary?

Gut cleansing is a complete reset of your gut, carried out in three steps:


  1. Gut cleaning: This is the most unpleasant part. A colon cleanse empties your gut completely.

  2. Detoxification: The intake of detoxifying minerals removes toxins and bad bacteria from your gut.

  3. Rebuilding the gut flora: Now follow all the measures we will explain to you later in this article.


There is no scientific evidence that gut cleansing is necessary or even helpful for rebuilding a healthy gut flora. However, there are many positive personal testimonials. If you’re considering this method, you should discuss it with your doctor beforehand.


Rebuilding gut bacteria through proper nutrition

Nutrition plays a key role in rebuilding the gut flora. You should avoid all foods that negatively affect the microbiome. At the same time, you can provide your body with nutrients that help the healthy gut bacteria grow.


  • What you should avoid: Sugar is the biggest enemy of a healthy gut flora. Why? Because it serves as a breeding ground for bad bacteria and fungi that disrupt the delicate balance of your gut flora. Avoid sugar and all highly processed foods with many artificial additives – such as sweet pastries or ready-made meals. Saturated fats should also be largely eliminated.

  • What you should eat: Fiber is indigestible food components that act as food for healthy gut bacteria. When rebuilding your gut flora, you should eat a diet rich in fiber – at least 30 grams per day. You can support the colonization of gut bacteria by consuming probiotic foods. These are foods that naturally contain healthy gut bacteria – such as natural yogurt, kefir, or sauerkraut.


Important – don't expect too much too quickly: It is possible to restore the balance of the gut flora through proper nutrition alone. However, this does not happen overnight and requires a lot of discipline. A permanent change in diet is key to success.


Avoiding stress

Excessive physical and mental stress negatively impacts your entire body, particularly your gut. Why? Because the stress hormone cortisol increases inflammation in the gut. This damages the intestinal lining and causes healthy gut bacteria to die off gradually. In addition to a healthy diet, it is important to avoid stress and actively promote relaxation.


Exercise is a proven method for both goals. An intense workout reduces stress, after which you can relax wonderfully. Additionally, relaxation methods such as autogenic training, progressive muscle relaxation, or simple meditation exercises are recommended.


Taking gut bacteria – Probiotics for quick colonization of gut bacteria

Probiotics help you speed up the rebuilding of gut flora. These are dietary supplements that contain healthy and viable gut bacterial strains. In short, you can take gut bacteria and ensure the colonization of healthy bacterial strains yourself. It is important to use a high-quality product for this. Cheap mass-produced products often have an unfavorable composition and contain unnecessary fillers and additives. According to scientific studies, this can even have a negative effect on your gut.


PROBIOTIC was developed in collaboration with leading gut experts and clinically tested by Japanese and German research partners and academic institutions. The preparation follows the human biotic pattern, which is a unique composition of human gut bacteria and high-quality prebiotics – without any useless fillers and additives. PROBIOTIC helps you quickly rebuild gut bacteria and benefit long-term from the positive effects of a healthy gut flora – including more energy, a stronger immune system, and fewer digestive issues.


  • Strong human gut bacteria: PROBIOTIC contains gut bacteria that naturally occur in your gut – and they are very resilient. They deprive bad bacteria of their living conditions and accelerate the rebuilding of your gut flora.

  • High-quality prebiotics: To speed up the growth of bacterial strains, PROBIOTIC contains selected prebiotics – acacia fiber and Nutriose. These are fibers that serve as food for the good gut bacteria and promote quick colonization. We deliberately avoid inulin, a prebiotic that ferments very quickly and can cause bloating and diarrhea.

  • Acid-resistant DRCaps®: Special hard capsules ensure that the healthy gut bacteria reach the gut unharmed and can exert their effect there.

  • Constant laboratory testing: The bacterial strains contained in PROBIOTIC undergo constant laboratory testing. Through regular microscopic examinations, we ensure that we maintain our high-quality standards over the long term.
