What's Chaga
Inonotus obliquus — Chaga — is one of the most studied functional mushrooms in nutritional science, valued across multiple herbal traditions in Siberia, Japan, Korea, China, and Northern Europe for centuries; Gribb cultivates it on their own certified-organic farm in Portugal under PT-BIO-10, in controlled indoor conditions that guarantee traceability, purity, and batch-to-batch consistency impossible to achieve with wildcrafted material.
Gribb's Chaga is dual-extracted — hot water extraction to release the water-soluble beta-glucans (β-1,3/β-1,6), polysaccharides, and polyphenols, and organic alcohol extraction to capture the fat-soluble triterpenoids and other lipophilic compounds — producing a full-spectrum tincture standardised to 32–40% beta-glucans (β1,3/β1,6)
This product is not intended to diagnose, treat, cure, or prevent any disease.

SPECIFICATIONS
Every gram tracked from spore to bottle
Wildcrafted Chaga has no supply chain traceability — origin, age, contamination exposure, and heavy metal content are unknown variables. Gribb's indoor cultivation means every batch is traceable to the exact growing conditions, substrate, and harvest date. PT-BIO-10 certified at every stage.
Consistency
Standardised beta-glucans every batch — not estimatedWild Chaga polyphenol and beta-glucan content varies dramatically with geography, tree species, age, and harvest season. Gribb's controlled conditions produce consistent beta-glucan levels, standardised to 32–40% (β1,3/β1,6) and lab-tested every batch. The potency you read on the label is the potency you receive.
Purity
No heavy metals, pesticides, or environmental contaminationWild Chaga grows in forests exposed to acid rain, industrial pollution, and heavy metal deposition — Siberian and Northern European forests are not pristine. Indoor organic cultivation eliminates all environmental contamination risk. Certified organic substrate. Controlled water supply. No exposure to external pollutants.
Verified Bioactives
The same β-1,3/β-1,6 glucan confirmed by sciencePeer-reviewed research comparing cultivated and wild Inonotus obliquus confirms the same mixed-linkage β-1,3/β-1,6 glucan structure in both. Cultivated Chaga also produces melanin — eumelanin, the form found in human skin — and the full spectrum of polyphenols and triterpenoids produced by the fungus itself. The core bioactives are present and verified.

What to expect
Ritual beats intensity. Same time, every day. That's the whole game.
WEEK 1–2
Your body is absorbing and adjusting to the blend. The functional mushrooms
and adaptogenic botanicals need time to build in your system — most people
notice little change yet and that is completely normal. Stay consistent.
WEEK 3
This is usually when subtle shifts begin. Days feel slightly more even. The
afternoon dip that used to derail you starts to feel less sharp. Not a spike —
a steadier floor.
MONTH 1+
The cumulative effect. Most people at this point notice the difference on the
days they forget to take it. The vitality feels like yours — not something
borrowed from caffeine.

Why dual extraction matter
Most functional mushroom products use a single extraction — which means they only capture part of what this mushroom has to offer.
Gribb's tincture uses a dual-extraction process: first with hot water to release the water-soluble beta-glucans, then with organic alcohol to extract the fat-soluble compounds. The two extracts are then combined into a single, full-spectrum liquid. It's a more time-intensive method — and the reason this tincture delivers what a capsule or powder alone cannot.

Frequently Asked Questions
Deliberate choice — and a meaningful one. Wildcrafted Chaga from Siberian or Northern European forests has no supply chain transparency: origin, environmental contamination exposure, heavy metal content, and harvest age are unknown variables that cannot be verified after the fact. Gribb cultivates Inonotus obliquus in controlled indoor conditions on their certified-organic farm in Portugal, which means every batch is traceable from spore to bottled tincture, grown on certified-organic substrate, free from pesticides, heavy metals, and environmental pollutants, and harvested at an optimised stage for bioactive content.
The science is clear on the core question: peer-reviewed research comparing cultivated and wild Inonotus obliquus confirms that the same mixed-linkage β-1,3/β-1,6 glucan — the primary polysaccharide of scientific interest in Chaga — is present in both cultivated and wild material. Cultivated Chaga also produces melanin (eumelanin, the form found in human skin, with its own research interest in antioxidant and neuroprotective properties), polyphenols, polysaccharides, and triterpenoids — all compounds produced by the fungus itself rather than derived from a tree host. What cultivated Chaga offers that wildcrafted cannot is verified consistency: standardised to 32–40% beta-glucans (β1,3/β1,6) and lab-tested every batch, so the potency on the label is the potency you receive. Wild Chaga potency varies significantly by geography, age, and season and cannot be standardised.
Yes — cultivated Inonotus obliquus produces melanin. Specifically, it produces eumelanin— the same form of melanin found in human skin — derived from L-DOPA pathways. This is distinct from the allomelanin produced by wild conk, but it is a genuine melanin with its own documented antioxidant properties and ongoing research interest. The melanin in Chaga is part of what gives the fungus its characteristic dark pigmentation and contributes to its polyphenol density. In Gribb's dual-extracted tincture, both the water-soluble and fat-soluble fractions are captured, ensuring the full melanin-associated polyphenol profile is present in every serving.
Chaga is one of the functional mushrooms where dual extraction matters most. The water-soluble stage (hot water) releases beta-glucans, polysaccharides, and water-soluble polyphenols — the compounds most studied in Chaga research. The organic alcohol stage captures triterpenoids, fat-soluble phenolic compounds, and other lipophilic bioactives that a hot water extraction leaves behind entirely. A single-extracted Chaga product — or a raw powder — provides only the water-soluble layer. Gribb's dual extraction combines both stages into a single full-spectrum tincture, standardised to 32–40% beta-glucans (β1,3/β1,6) to confirm the water-soluble fraction, with the alcohol stage ensuring the fat-soluble compounds are fully captured alongside it.
Chaga has been used across multiple independent herbal traditions for centuries. In Siberian folk medicine it was traditionally prepared as a hot water decoction and consumed as a daily beverage for general vitality and wellbeing. In Japanese tradition it is known as "the diamond of the forest" and has been used in Japanese herbal practice for generations. Korean and Chinese herbal medicine have each independently valued Inonotus obliquus for its polyphenol-rich profile. Norwegian and Finnish folk medicine documented its use for centuries in Northern Europe. This convergence of multiple geographically separate herbal traditions each independently discovering and valuing the same mushroom reflects the depth of its naturally occurring bioactive compounds — something that lab cultivation preserves fully while adding the traceability and purity that traditional foraging could never provide.
Yes — every mushroom is grown in our own certified-organic urban farm in Portimão, Portugal. We grow them ourselves from spore through to harvest. Nothing is imported from third-party suppliers or rebranded from elsewhere.
Our production is certified organic by NATURALFA (PT-BIO-10) and every batch is third-party tested before it ships. Full traceability from farm to your door.
Yes — the tincture contains 20–30% organic alcohol, which is required for the dual-extraction process and acts as a natural preservative. At a standard 1ml dose, the amount is very small. To minimise it, add the drops to a hot drink — the heat causes most of the alcohol to evaporate quickly without affecting the mushroom compounds.
Take 1 full dropper (1ml / approx. 20 drops) up to twice daily. For fastest absorption, hold it under the tongue for 30–60 seconds before swallowing. Alternatively, add it directly to any hot or cold drink. Most people find the easiest approach is to add it to their morning coffee or tea — it becomes habit immediately and you never forget a dose.
Each 50ml bottle contains approximately 50 daily servings at the recommended 1ml dose. At once daily, that's roughly 7 weeks. At twice daily, approximately 3–4 weeks.
Yes — this tincture is designed for daily use as part of a consistent wellness routine.
As with any supplement, if you are pregnant, breastfeeding, have a medical condition, or are taking medication, please consult your healthcare provider before starting. This is a food supplement, not a medicine, and is not intended to diagnose, treat, cure, or prevent any disease.
