Bye-bye flu!

Stay fit through cold season with a natural immune boost

In the cold season, a strong immune system is our best ally against colds and fatigue. Natural remedies, balanced gut health, and targeted nutrients can help us get through the winter healthy and active. From tried-and-tested classics to real insider tips: We’ll show you how you can strengthen your defenses gently yet effectively.

Flu or cold? Learn the difference and protect yourself better

Flu or cold? The terms are often confused, even though the two illnesses differ significantly. A cold is usually milder and develops gradually with coughing, a runny nose, and hoarseness. The flu, on the other hand, starts suddenly, often with a high fever, headaches, and aching limbs, and can put a heavy strain on the body.

From a naturopathic perspective, the flu can be seen as a “cleansing process” of the body – a natural, body-owned detox function that helps eliminate burdensome substances and strengthen the immune system. Fever, coughing, and a runny nose are more than just symptoms; they support the removal of everything that does not belong in the body. Some even view the flu as the body’s way of telling us to allow ourselves the rest we need and to trust our natural defenses.”

The best natural home remedies for flu and colds – Simple and effective

Before we look at specific dietary supplements for the immune system, it is worth taking a look at time-tested home remedies that are often passed down from generation to generation. They are easy to use, readily available, and gently support your body without overwhelming it.

  • Hot drink made with ginger, lemon, and turmeric:
    This combination brings together the power of three natural remedies. Ginger warms and has anti-inflammatory effects, turmeric strengthens the immune system, and lemon juice provides valuable vitamin C. Simply steep fresh ginger slices and a pinch of turmeric in hot water and add a little fresh lemon juice shortly before drinking.
  • Thyme tea:
    Thyme is a proven remedy for coughs and soothes the airways. A tea made from fresh or dried thyme also has antibacterial properties and supports overall well-being.
  • Bone broth:
    Bone broth is rich in minerals, amino acids, and collagen – a true superfood for the cold season. It supports regeneration and strengthens the body. On our website, you’ll find a recipe for easily preparing this nutrient-rich broth yourself.
  • Calf wraps:
    In cases of fever, cold calf wraps can help gently lower body temperature. They have a calming effect and promote circulation.
  • Inhalations:
    Steam with essential oils such as chamomile or thyme can open the airways and loosen mucus. Ideal for a blocked nose or cough to help clear the airways.
  • Warm baths and foot baths:
    A warm bath or hot foot bath promotes circulation, helps the body relax, and can strengthen the immune system. Additives such as eucalyptus or lavender oil are especially soothing.

These home remedies offer valuable initial support. Combined with targeted immune system strengthening through a healthy microbiome and glutathione, they can optimally prepare the body for cold season.

Your gut as an immune booster: Why 80% of defense cells are located here

A healthy gut is crucial for a strong immune system. Around 70–80% of immune cells are located there and protect your body from pathogens. A balanced gut acts like a natural barrier against many typical complaints that trouble us especially during cold season.

This is exactly where our ActiveBravo Probiotic comes in: This high-quality probiotic strengthens the natural balance of your microbiome and promotes the colonization of “good” bacteria in the gut. These support immune defense by warding off harmful microorganisms – for a natural strengthening of your immune system.

A little insider tip:
Your microbiome produces important messenger substances that regulate the immune system and thus form a healthy line of defense. A balanced microbiome ensures that your body can better recognize and fight off pathogens. Especially in the winter months, when our immune system is challenged by cold and less sunlight, a stable microbiome can help you stay healthy and resilient.

To optimally support the good gut bacteria, they also need prebiotic nutrients – the “food” for their growth. Fiber-rich and at the same time keto-friendly prebiotics such as chicory root, Jerusalem artichoke, and dandelion root are particularly suitable. Another ideal addition is our ColoStabil: This formulation combines valuable fiber and supports the natural movement of the gut. Together with ActiveBravo Probiotic, you create the perfect foundation for a resilient microbiome and strengthened immune defense.

By the way, a balanced gut does even more for you: It helps optimally absorb important nutrients and supports the body in feeling good all around. This way, you can get through the winter with a strong immune system and full of energy.

Glutathione – The ultimate protective shield for your immune system during cold season

Glutathione is one of the body’s most powerful antioxidants and acts as a natural “protective shield” against harmful substances and stressors that burden the immune system. It not only helps your body fight off pathogens, but also supports detoxification – especially valuable during cold season.

N-Acetylcysteine (NAC) – More than just a mucus thinner

Our product “Glutathion Comp” contains N-acetylcysteine (NAC), a valuable active ingredient that can additionally support immune defense during cold season. As a building block of glutathione, NAC has antioxidant and anti-inflammatory effects – properties that are especially important during cold season. In addition, NAC helps loosen stubborn mucus in the airways, providing relief for coughs and congested airways.

But that’s not all: NAC also supports our immune cells, especially granulocytes, which act as “first responders” in defending against pathogens. Through this comprehensive effect, NAC strengthens the body and helps protect it naturally against colds and flu.

Our Glutathion Comp addresses exactly this: With a high-quality formulation, it helps your body replenish glutathione reserves and reduce oxidative stress – for targeted relief and strengthening of the immune system.

A little insider tip:
Glutathion Comp contains N-acetylcysteine (NAC), a special form of the amino acid cysteine that serves as a direct precursor to glutathione. NAC is known to act as an antioxidant and protect the mucous membranes of the airways. Especially during colds and flu season, it supports the body in loosening mucus and relieving the airways – an often underestimated aid for free breathing in winter.

N-Acetylcysteine: The all-rounder for strong defenses and clear airways

N-acetylcysteine (NAC) was originally developed in the 1960s as a mucus thinner for respiratory diseases. Today we know that NAC can do much more: It has anti-inflammatory and antioxidant effects and supports the immune system in detoxification. White blood cells in particular – our first line of defense – benefit from NAC, as it supports their work against pathogens and dead cells. NAC is therefore a true all-rounder for cold season.

With Glutathion comp, you not only supply your body with a powerful antioxidant, but also create the basis for faster recovery and stable defenses – so you can get through cold season healthy and full of energy.

Proven home remedies such as strengthening hot drinks or nutrient-rich bone broth, combined with targeted gut health through probiotics and prebiotic fiber, promote defenses gently and effectively.

A strong microbiome in the gut, which strengthens around 70–80% of immune cells, and the antioxidant glutathione as a protective shield against stressors prepare you in the best possible way.
