Breathe Freely with Spirosol

Cold, dry weather, pollen, or polluted air can strain the bronchi and lead to mucus-producing coughs. Spirosol supports easy breathing all year round: N-acetyl-L-cysteine helps loosen stubborn mucus, quercetin soothes irritated airways, and vitamin C as well as zinc can strengthen the body’s cellular defense.

Dr. Viktor Jurk especially recommends Spirosol for those suffering from chronic respiratory conditions such as bronchitis or COPD. It can also help smokers or people in polluted environments by making it easier to cough up mucus and cleanse the lungs.

When taken regularly, it may support the regeneration of the airways, reduce the risk of new lung conditions, and restore your energy. Give yourself the freedom to breathe easily again. Trust in Heilnatura and Dr. Viktor Jurk: breathing is life.

Breathe freely with Spirosol

How Spirosol Works

Spirosol is a doctor-developed dietary supplement designed to support normal lung function. Its ingredients are combined to help reduce inflammation, loosen mucus, and promote the natural self-cleaning process of the airways.

Spirosol does not replace medical treatment for bronchitis or other conditions, but serves as a supportive companion. It contains the following active ingredients:

  1. Quercetin: This powerful antioxidant flavonoid may reduce inflammation in the airways and protect cells from oxidative stress caused by environmental toxins or smoke, supporting lung cell regeneration and relieving persistent cough.
  2. N-acetyl-L-cysteine (NAC): As a precursor to the body’s antioxidant glutathione, NAC helps liquefy thick mucus, making it easier to cough up while supporting lung detoxification.
  3. Bitter orange extract: Contains synephrine and other bioactive compounds that may dilate the bronchi, ease breathing, and provide antibacterial effects.
  4. Thyme extract: Rich in essential oils such as thymol and carvacrol, thyme has mucus-loosening, antibacterial, and antiviral properties.
  5. Cordyceps sinensis: May support oxygen uptake, reduce inflammation, and strengthen the immune system.
  6. Zinc: Supports the body’s defenses against respiratory infections.
  7. Selenium: Protects the lungs from free radicals and supports immune response.
  8. Riboflavin (vitamin B2): Promotes energy production in respiratory cells.

Through this targeted combination of plant extracts, vitamins, trace elements, and antioxidant components, Spirosol supports respiratory health holistically and may help ease breathing while promoting recovery.

Pro-Biosan
Regular price: From €15.90

Contents and Dosage of Pro-Biosan Capsules Recommended Use: Take 2×2 capsules of the Biosan Complex daily, ideally before meals, with sufficient liquid. Content: 60 capsules per pack Ingredients: Guar gum powder, bacterial strains, psyllium husk powder, black cumin extract Ingredients / 4 Capsules Amount Guar gum powder 200 mg Bacterial strain blend 800 mgequivalent to 2.5 billion CFU/g** Psyllium husk powder 720 mg Black cumin extract 240 mg Biosan for Supporting the Gut Flora Our Heilnatura Pro-Biosan is a highly effective dietary supplement in convenient capsule form, specifically designed to support gut health. The combination of carefully selected lactobacilli, additional probiotic bacteria, and valuable micronutrients helps stabilize the intestinal flora and supports the body’s energy and metabolic processes. Complemented by psyllium husk powder and black cumin extract, Biosan can help reduce inflammation, strengthen the immune system, and sustainably promote intestinal function. Effects of Biosan Our Pro-Biosan Complex supports gut health on an individual level by addressing the specific needs of your digestive system. A balanced gut flora and proper digestion are essential for vitality, energy, and overall well-being. Products like Pro-Biosan combine lactic acid–producing bacterial cultures with dietary fibers such as psyllium husks and black cumin extract to support the gut on multiple levels—from bacterial balance to natural intestinal movement. Below are some of the benefits of the ingredients: Regulation of Digestion Psyllium husks are swelling dietary fibers that bind water and increase stool volume, gently stimulating natural bowel activity. This can be helpful for both constipation and irregular bowel movements. They also have a prebiotic effect, serving as food for beneficial gut bacteria and promoting a healthy microbial environment. The black cumin extract further supports digestion, soothes mucous membranes, and can help relieve bloating or cramps. Support of the Gut Flora The quantity of bacteria included and the carefully selected lactic acid–producing cultures contribute to stabilizing the gut flora through their specific properties. Contribution to Energy Production and Nutrient Absorption A healthy gut improves nutrient absorption. Since certain probiotic strains produce digestive enzymes, they facilitate the breakdown of food components. This can help reduce tiredness and fatigue, as the body is able to convert nutrients into energy more efficiently. Protective Support During Stressors Such as Antibiotics During or after antibiotic therapy, the gut flora can become imbalanced. Probiotics support the recolonization of the gut with beneficial bacteria, while psyllium husks provide a mild, balancing effect on digestion. Black cumin extract additionally helps soothe the gastrointestinal tract. Support of the Immune System A large part of the immune system is located in the gut. Probiotics can help improve the balance of intestinal bacteria and thereby strengthen immune function. Overall, the combination of probiotic strains and prebiotic fibers creates a favorable environment for bacterial diversity and stable digestive function. This synergy enhances the positive effects on gut health and energy balance. Buy Pro-Biosan from Heilnatura In our shop, you can purchase the Pro-Biosan Complex, a carefully developed dietary supplement designed to support gut health. With a combination of probiotic bacterial cultures, psyllium husks, and black cumin extract, it promotes digestion, micronutrient absorption, and energy metabolism—for a high-performing “power organ” gut.
