Product information "Heilnatura Spirosol"

PLEASE NOTE THE INDICATED DELIVERY TIME!

Damp and cold weather puts our lungs to the test: cold, dry air and constant temperature changes irritate the bronchi, and stubborn mucus-producing coughs are quick to follow. But whether it’s frost, spring pollen, or summer smog, Spirosol helps you breathe freely all year round. The balanced formula with N-acetyl-L-cysteine liquefies stubborn mucus and makes it easier to cough up, quercetin soothes inflamed airways, and vitamin C and zinc strengthen cellular defenses.

Spirosol supports the treatment of bronchitis, clears the lungs of pollutants, and provides noticeable relief, especially for smokers’ lungs or those exposed to polluted environments. Taken regularly, it promotes the regeneration of the respiratory tract, reduces the risk of new lung diseases, and gives you the energy that comes with every deep breath. Treat yourself to the freedom of breathing with ease again. Trust Heilnatura and Dr. Viktor Jurk: Breathing is life.

FAQ

Spirosol by Heilnatura is a physician-developed dietary supplement by Dr. Viktor Jurk, designed to support normal lung function. The unique formula combines eight powerful natural ingredients tailored to the needs of your lungs.

The product is especially supportive as an adjunct measure in the management of bronchitis and helps with stubborn mucus cough. The balanced formula with 200 mg of quercetin and 150 mg of N-acetyl-L-cysteine thins thick mucus and makes expectoration easier, while quercetin soothes inflamed airways.

Spirosol is particularly valuable for people who want to cleanse their lungs, whether due to environmental exposure, for lung regeneration in smokers, or with recurrent respiratory issues. It does not replace medical treatment, but it is a helpful companion for healthy airways.

Spirosol offers numerous benefits for your respiratory health:

  • For chronic respiratory issues: Dr. Jurk especially recommends Spirosol for people with chronic conditions such as bronchitis or COPD. Ingredients like N-acetyl-L-cysteine help thin mucus in the airways and make expectoration easier, while quercetin calms irritated airways.
  • Natural lung cleansing: Spirosol supports the airways’ self-cleaning and helps cleanse the lungs, which is particularly important for smokers and for people exposed to pollutants, smoke, or fine dust.
  • Relief for persistent symptoms: With stubborn cough with or without mucus, the combination of NAC, thyme extract, and bitter orange extract is expectorant and antibacterial. This effectively supports bronchitis management as part of an overall therapy plan.
  • Protection against lung disease: The antioxidant properties of quercetin, zinc, and selenium protect against free radicals and may lower the risk of chronic pulmonary conditions.

Spirosol is simple and convenient to take:

Dosage: Take one Spirosol capsule by Heilnatura daily with plenty of water. No confusing dosing and no top-ups. While many brands split the daily dose into several servings, one capsule of Spirosol covers the entire day.

Best time to take it: Aim for the same time every day, ideally right after waking up in the morning. This gives your airways optimal support to start the day.

Duration of use: The recommended duration depends on individual needs, so there is no one-size-fits-all guidance. For adjunct support in bronchitis or for ongoing lung cleansing in smokers, longer-term use may be appropriate.

Important notes: Spirosol contains carefully combined plant extracts and bioactive compounds and is not recommended during pregnancy or breastfeeding. Speak with your doctor or midwife before use.

Dr. Jurk’s vision: “Breathing is life.” This guiding principle reflects his belief that free, unburdened breathing is the foundation of vitality and quality of life. The program is based on the insight that our airways face daily stressors from cold, dry air to pollen, smog, and fine dust.


Spirosol is suitable for the following applications, among others:
  • Prevention during the cold season: protect lung function against infections
  • Support for chronic issues: help in the management of bronchitis and stubborn cough
  • Regeneration for stressed lungs: especially for smokers and for people in polluted environments

The program aims to promote natural lung cleansing, prevent respiratory diseases, and help everyone tap into the energy that comes with every deep breath.

The Spirosol capsules by Heilnatura contain carefully combined plant extracts and bioactive compounds such as quercetin, bitter orange extract, and cordyceps, which are not recommended during pregnancy or breastfeeding. If you are pregnant, nursing, or planning a pregnancy, consult your physician or midwife before use.

Ich seit 14 Jahren COPD und suche schon länger nach einer Alternative zur Schulmedizin. Seit 4 Wochen nehme ich nun Spirosol und bin begeistert über die Wirkung. Meinen Medikamentenverbrauch habe ich drastisch einschränken können. Mir geht es auch ohne Cortison gut. Danke dafür

Bewertung von Ernst C.

unglaublich Ich habe von dem Produkt durch Werbung bei Telegram erfahren. Es hörte sich gut an und ich bestellte es. Dann lass ich bei "google", dass Spirosol ein Mittel für lungenkranke Pferde sei und war sehr enttäuscht. Die Not bei mir war aber so groß, dass ich es trotzdem probierte. Und siehe da ........ unglaublich........ das ist besser als alles was mir der Arzt bisher verordnet hat und zumindest bei mir ohne jegliche Nebenwirkung. Die Kurzatmigkeit ist sehr spürbar zurückgegangen, das Leben fühlt sich wesentlich besser an.

Content: 90 Capsules (€0.27* / 1 Capsules)

From €24.00* (previously €27.90*)
Our premium milk-thistle capsules contain a standardized extract from the seeds of milk thistle (Silybum marianum), a time-honored member of the Asteraceae family. With its purple thistle-like blossoms and white-marbled leaves, the plant has been prized for centuries and is now considered the world’s most researched liver herb. Each capsule delivers a consistent 80 % silymarin content for reliable potency. The seeds naturally supply silymarin, a complex of bioactive flavonoids (silybin, silychristin, silydianin) with strong antioxidant properties. Milk-thistle liver formulas have been valued for hundreds of years and are now the focus of intensive research. Effect Heilnatura milk-thistle capsules provide carefully extracted silymarin. Discover what this remarkable plant extract can do: May support treatment of liver conditions such as cirrhosis by acting as an adjunct. Could help lower cholesterol levels. The silymarin extract reaches peak plasma levels 1.5 hours after ingestion. Studies show significant improvements in key liver markers: ALT and AST can drop markedly. May reduce fat accumulation in the liver (hepatic steatosis). Helps stabilize liver-cell membranes and may shield them from harmful substances. Silymarin can boost protein synthesis and activate DNA-repair pathways, promoting healthy cell regeneration and the removal of toxins. Dosage Suggested use Take two milk-thistle capsules daily.

Pro-Biosan

From €24.90* (previously €29.90*)
Heilnatura Pro-BiosanBacterial strain blends, especially in the form of probiotics, offer various benefits for gut health and overall well-being. Both psyllium husk powder and black seed extract are often used to support digestion, gut health, anti-inflammation and the immune system. Below are some of the benefits of the ingredients:Improved intestinal health: Probiotics contain beneficial strains of bacteria that can support the intestinal flora. Healthy intestinal flora is important for good digestion, the absorption of nutrients and strengthening the immune system. Strengthening the immune system: A large part of our immune system is located in the gut. Probiotics can help to improve the balance of intestinal bacteria and thus strengthen immune function. Improvement of digestion: Probiotics can help reduce digestive disorders such as bloating, constipation or diarrhea by restoring the healthy bacterial population in the gut. Support with food intake: Some strains of bacteria in probiotics produce enzymes that can help with the digestion of food and the absorption of nutrients. Prevention of antibiotic-associated problems: Antibiotics can also destroy beneficial gut bacteria. Taking probiotics during and after antibiotic treatment can help maintain the balance of gut flora and reduce diarrhea or other associated problems. A combination of different strains can produce synergistic effects and better support digestive health.Consumption recommendation:  Take 2x2 capsules daily before a meal with plenty of liquid.Inhalt:  60 capsules Ingredients (4capsules):  Ingredients                              share Guarkernmehl Pulver              200mgBacterial strain mixture          800mg corresponds to 2,5 Mrd.
