Why does gut health matter?
Your gut is the center of your health. It influences your immune system, your energy, your mood and much more. With the right products, you can support it in a targeted way.

Stronger Immune System
About 70% of the immune system is located in the gut. A healthy gut flora strengthens your body's natural defense sustainably.
More Daily Energy
Optimal nutrient absorption in the gut supplies your body more efficiently – you feel fitter and more productive.
Better Concentration
The gut-brain axis influences your mental clarity. A healthy gut promotes focus and cognitive performance.
Improved Digestion
Fiber and healthy gut bacteria ensure smooth digestion and fewer discomforts.
Balanced Mood
95% of serotonin is produced in the gut. A healthy gut flora supports your emotional well-being.
Balanced Cholesterol Levels
One of the eight fibers consists of beta-glucans from oats. These play a role in maintaining normal blood cholesterol levels.

Health Reflection Questionnaire
The reflection questionnaire is a personal tool that helps you consciously reflect on your current health situation. It covers areas such as body, mind, substance consumption, and general energy level.
Ideally, you fill out the questionnaire before or at the beginning of taking your products and repeat it after 120 days to visualize possible changes.

A healthy gut microbiome, omega-3 fatty acids, and vitamin D are closely interconnected. Only when all three building blocks are in balance can your body function optimally.
How a powerful synergy is created
- A healthy gut flora significantly improves the absorption of vitamin D and omega-3 fatty acids.
- Omega-3 fatty acids have anti-inflammatory effects and support the gut barrier.
- Vitamin D regulates the immune system in the gut and positively influences the composition of gut bacteria.
- Studies show: People with higher omega-3 levels often also have better vitamin D levels.
