Capsule Information
The simplest way to fortify your immune defences
High-dose Chaga. No underdosing.
More antioxidants and beta-glucans per serving. Clinically meaningful levels for immune support and oxidative stress protection.
Concentrated for immune resilience, cellular protection, and whole-body wellness.
Nothing added. Nothing diluted.
Dosage information
Each capsule contains equivalent to 2,500mg of Ultrasonic Triple-Extract Chaga Mushroom Powder. 5x the standard industry dose. Most people notice improved resilience to seasonal challenges and overall wellbeing within 14-30 days of consistent use.
Extraction process
Step 1: Ultrasonic Cell Disruption
Ultrasonic waves are passed through a liquid containing mushroom fruiting body. This breaks open the chitin cell walls of the mushroom, dramatically improving extraction efficiency and preserving delicate compounds.
Step 2: Hot Water Extraction
This isolates water-soluble polysaccharides like beta-glucans, which support immune and gut health.
Step 3: Ethanol Extraction
The remaining mushroom solids are soaked in ethanol (often 30–70%). This extracts alcohol-soluble compounds such as triterpenes, cordycepin, and ergosterols, depending on the species (especially important for Reishi, Chaga, and Cordyceps).
The collected extracts (from water and alcohol phases) are combined, concentrated under low heat, and then spray-dried or freeze-dried into a powder.

Questions?
We’re here to help
Is the dose strong enough to do anything?
Yes. Our capsules contain clinical doses – the same amounts used in peer-reviewed studies that showed measurable results. Most high street supplements contain 200-500mg of mushroom extract. We use 2,000-2,500mg per serving. That's the difference between trace amounts and functional doses. Lion's Mane at 2,500mg improved cognitive test scores in clinical trials. Reishi at 2,000mg reduced cortisol response by 27%. Cordyceps at 2,500mg enhanced ATP production and endurance. We don't do fairy dusting. If it's in the capsule, it's there to work.
How long does it take to feel results?
It varies by mushroom and person, but most people notice shifts within 7-14 days. Mental clarity from Lion's Mane often appears within the first week. Energy improvements from Cordyceps can be felt within days. Stress resilience from Reishi builds over 2-4 weeks as your nervous system adapts. Immune support from Chaga and skin benefits from Tremella compound over 30-90 days. Functional mushrooms aren't stimulants – they work with your body's systems, so consistency matters more than immediate effects.
Is this safe to take every day?
Yes. Functional mushrooms have been consumed daily for centuries in traditional medicine and are recognized as safe by modern research. Clinical studies use daily dosing protocols for 8-12 weeks with no adverse effects. Our mushrooms are organic, third-party tested for heavy metals and contaminants, and contain only fruiting body extracts – no fillers, mycelium, or grain. If you're pregnant, breastfeeding, or on prescription medication, consult your healthcare provider before starting any new supplement.
Are these ‘magic mushrooms’?
No. Functional mushrooms are completely legal and non-psychoactive. They contain zero psilocybin or any hallucinogenic compounds. Species like Lion's Mane, Reishi, Cordyceps, Chaga, and Tremella are medicinal mushrooms valued for cognitive, immune, and adaptogenic benefits – not psychoactive effects. They work by delivering bioactive compounds like beta-glucans, triterpenes, and polysaccharides that support your body's natural systems. Think of them as nutrient-dense functional foods, not recreational substances.
Can I take this with medication?
Functional mushrooms are generally safe alongside most medications, but we always recommend consulting your doctor or pharmacist first – especially if you're taking immunosuppressants, blood thinners, or diabetes medication. Reishi may have mild blood-thinning properties. Cordyceps can affect blood sugar regulation. While interactions are rare, your healthcare provider knows your full medical history and can give personalized guidance. When in doubt, ask a professional.
Why are our capsules better than high street stores?
Three reasons: dose, extraction, and source.
Dose: High street brands often use 200-500mg of mushroom powder per capsule. We use 2,000-2,500mg of concentrated extract – clinical doses proven to deliver results.
Extraction: Most high street products use raw mushroom powder or single extraction, leaving bioactive compounds locked inside indigestible cell walls. We triple-extract to break down chitin and release beta-glucans, triterpenes, and polysaccharides your body can actually absorb.
Source: We use 100% organic fruiting bodies, not mycelium on grain (which dilutes potency with filler). Third-party tested for purity. No unnecessary ingredients. Just functional compounds at doses that work.
Are the claims actually backed by science?
Yes. Every benefit we mention is referenced from peer-reviewed clinical studies. Lion's Mane improving cognitive function: published in multiple journals including studies showing improved test scores in Alzheimer's patients. Reishi reducing cortisol: documented in stress response studies. Cordyceps enhancing ATP production: verified in exercise performance research. Chaga's antioxidant activity: measured in oxidative stress marker studies. Tremella's hydration benefits: studied for polysaccharide water retention. We link to research on every product page. No vague claims. No pseudoscience. Just clinical data.
Are your products third party tested?
Yes. Every batch is third-party tested for heavy metals (lead, arsenic, mercury, cadmium), microbial contamination, and pesticide residues. We also verify beta-glucan and active compound content to ensure you're getting what's on the label. Certificates of analysis are available on request. We don't just meet UK and EU safety standards – we exceed them. Quality control isn't optional when you're putting something in your body daily.
