Chaga – the “black gold of the forest”
In the heart of the northern forests, on the bark of birch trees, grows one of nature's most powerful treasures for cellular protection and repair - the chaga mushroom . With its rough black surface and highly concentrated nutrient profile, it has been used for centuries in Siberian and Scandinavian traditions to maintain resilience, vitality and longevity. Today, in conditions of chronic oxidative stress, a burdened liver and summer temperature extremes, chaga is becoming a relevant helper for the body - and not only in winter.
Cellular protection in a season of overheating
During the summer months, the body doesn’t just have to fight the heat outside – at a cellular level, it needs support to cope with heat stress, UV radiation and the accumulation of free radicals. Chaga is a natural concentrated formula for antioxidant protection. Extremely rich in melanins, polyphenols and betulinic acid , it acts as a shield for cells – neutralizing damaging molecules, supporting DNA regeneration and supporting the natural detox function of the liver.
Unlike other mushrooms, which primarily modulate the immune response through β-glucans, chaga has the unique ability to penetrate deeper into the antioxidant cascade – supporting the production of internal enzymes such as superoxide dismutase and catalase. Thus, it not only "quenches" already formed free radicals, but also contributes to long-term cell resistance.
Betulin – the natural guardian of the liver
One of the most notable ingredients in chaga is betulin , a triterpene that the fungus extracts directly from birch bark. Betulin and its derivatives have been studied for their ability to support liver function, modulate lipid profiles, and influence cell proliferation . This makes chaga especially valuable at times when the liver is under additional stress—such as dehydration, alcohol use, poor diet, or heat stress.
In addition, betulin has a soothing effect on the gastrointestinal mucosa, helping to improve absorption and barrier protection – especially important during seasonal disorders, travel or summer changes in the menu.
Immune resistance and energy tone
Chaga is both an adaptogen and an immunomodulator. It supports the normal activity of NK cells and macrophages without causing excessive stimulation. This makes it ideal for daily prophylaxis, especially for people with frequent infections, allergies or chronic fatigue. In the summer months, when the body spends more energy on thermoregulation, chaga can be used to maintain sustained focus, tone and metabolic balance , without the classic exhaustion effect that often follows caffeine or sugar.
Which Zia product contains chaga?
Zia ImmuniCare is rich in Chaga extract, extracted through a double extraction process that preserves both water-soluble β-glucans and fat-soluble terpenes like betulin. The formula is also fortified with other functional mushrooms such as Reishi, Lion's Mane and Maitake, making it a daily foundation for balanced immune, nervous and liver care .
Taking 2 capsules in the morning, especially in combination with adequate hydration and antioxidant food, creates a natural shield against internal overheating, oxidative stress and fatigue from the dynamic rhythm of summer.
