Quick Answer
BOOSTD Chaga Extract UK is a 50ml full-spectrum spagyric liquid extract of Inonotus obliquus — the King of Mushrooms. Alcohol-free, glycerin-based, with a 1:2.5 extraction ratio and reconstituted mineral salts for enhanced bioavailability. Rich in beta-glucans, triterpenes and chlorogenic acid. Traditionally used in Siberian and Northern European folk medicine for immune resilience and antioxidant protection.
BOOSTD Chaga Extract UK — The King of Mushrooms, Full-Spectrum
Chaga (Inonotus obliquus) is a parasitic fungus that grows on birch trees across the boreal forests of Siberia, Scandinavia and Northern Europe. It is technically a sterile conk — a dense sclerotium that takes 10 to 15 years to reach bioactive maturity. In Siberian and Northern European folk traditions it has been used for centuries as a tea and tonic for immune resilience, vitality and antioxidant protection. Its density of bioactive compounds — including beta-glucans, triterpenes and one of the highest concentrations of antioxidant phenols found in any natural substance — has made it one of the most researched functional fungi in modern science.
BOOSTD Chaga is not a powder or a capsule. It is a full-spectrum spagyric liquid extract — a form of extraction that preserves every fraction of the sclerotium, including the mineral salts that standard tinctures discard. The result is a 50ml alcohol-free extract in pharmaceutical-grade amber glass, delivering 1ml per day with a bioactive density that raw powder or simple tea cannot match.
The Bioactive Compounds in Chaga
Beta-glucans — specifically (1→3), (1→6)-β-D-glucans. These are biological response modifiers that interact with immune receptors to support the body’s natural immune regulation. Beta-glucans are the most studied class of compounds in functional fungi research.
Triterpenes — Inotodiol and Betulinic Acid — betulinic acid is sequestered from the birch host tree and concentrated within the fungal matrix. This is unique to Chaga growing on birch and is one reason why host tree species matters for Chaga quality.
Chlorogenic Acid — the dominant polyphenol in Chaga, quantified in published research at concentrations of 741 to 970mg per kg. A powerful antioxidant that contributes to Chaga’s role in supporting the body’s defence against oxidative stress.
Melanin — high-molecular-weight pigments found in the black exterior of the sclerotium. These contribute significantly to Chaga’s antioxidant profile and are responsible for its characteristic dark appearance.
Why Spagyric Extraction
Standard tinctures extract the bioactive compounds and discard the rest. Spagyric extraction goes further — the post-extraction biomass is calcined at high heat to recover purified mineral salts, which are then reintroduced into the liquid extract. These ionic mineral salts create an alkaline buffer that protects delicate phenolic compounds and facilitates superior cellular uptake through electrolyte-mediated signalling pathways.
The 1:2.5 extraction ratio means 1 part raw Chaga sclerotium produces 2.5 parts finished extract — a high-potency concentration. This allows a meaningful daily dose of 1ml while significantly reducing the oxalate load compared to raw powder consumption.
The extract uses pharmaceutical-grade vegetable glycerin as the solvent — not alcohol. Glycerin is a stable, gentle solvent that preserves bioactive compounds without denaturing them. The finished extract is stored in pharmaceutical-grade amber glass, which provides UV-C protection to prevent degradation of chlorogenic acid and other phenolic compounds.
What Chaga May Support
Immune Function — Beta-glucans act as biological response modifiers, supporting the body’s natural immune regulation. Preclinical research has examined Chaga’s role in modulating cytokine production including IL-6 and TNF-α. Human clinical evidence is limited and ongoing.
Antioxidant Protection — Chaga’s chlorogenic acid and melanin content give it one of the highest antioxidant densities of any natural substance studied. Antioxidant activity is well-established in vitro and supports the body’s defence against oxidative stress.
Inflammation Balance — Preclinical research using macrophage models shows Chaga extracts may reduce proinflammatory biomarkers dose-dependently. Modern research is examining the mechanisms involved in inflammatory pathway modulation.
Seasonal Resilience — Traditionally used in circumboreal cultures during periods of environmental stress and seasonal change to maintain general vitality. This traditional use aligns with modern understanding of beta-glucan immune modulation.

Product Questions
What is Chaga?
Chaga (Inonotus obliquus) is a parasitic fungus growing on birch trees across Siberia and Northern Europe. Technically a sterile sclerotium, not a fruiting body, it takes 10 to 15 years to reach bioactive maturity. Rich in beta-glucans, triterpenes, chlorogenic acid and melanin. More detail at The Science Behind Chaga.
What is a spagyric extract?
A spagyric extract separates and recombines all fractions of the source material. In standard tinctures the mineral fraction is discarded. In spagyric extraction the post-extraction biomass is calcined at high heat to recover purified mineral salts, which are reintroduced into the liquid extract to support bioavailability through ionic signalling.
Why is BOOSTD Chaga alcohol-free?
BOOSTD Chaga uses pharmaceutical-grade vegetable glycerin as the solvent. Glycerin is a stable, gentle solvent that preserves bioactive compounds without denaturing them and is suitable for those avoiding alcohol for health, personal or religious reasons.
What does the 1:2.5 extraction ratio mean?
1 part raw Chaga sclerotium produces 2.5 parts finished liquid extract. This high-potency concentration allows a meaningful daily dose of 1ml while significantly reducing oxalate load compared to raw Chaga powder consumption.
How do I take BOOSTD Chaga Extract?
1ml per day — one full pipette — directly under the tongue or mixed into water, juice or a warm drink. Store in a cool, dark place away from direct sunlight.
Is Chaga safe to take daily?
At the recommended 1ml daily dose, BOOSTD Chaga Extract is considered safe for healthy adults. The primary safety concern with Chaga relates to its calcium oxalate content — a concern associated with raw powder at very high doses (10g or more per day), not with a concentrated liquid extract at 1ml per day.
Who should not take Chaga?
Those with a history of kidney stones or chronic kidney disease should avoid Chaga due to its oxalate content. Those on anticoagulant medication should consult their GP. Those on blood sugar medication should consult their GP. Not recommended during pregnancy or breastfeeding. Not recommended for those under 18.
Can Chaga treat cancer?
No. Laboratory studies examining Chaga in relation to cancer cell pathways are strictly preclinical and research-context only. Chaga is not an approved treatment for any form of cancer or any other disease. It is a food supplement and must not be used to replace conventional medical treatment.
