Science Meets Nature
Kingdom Five takes its name from the Fifth Kingdom of Life — Fungi, a domain distinct from plants or animals, defined by its intelligence and interconnection. Fungi form the foundation of biological renewal, transforming and sustaining ecosystems through complex biochemical networks.
Our mushrooms are cultivated in Tasmania, an environment renowned for its purity. With some of the cleanest air, water, and soil in the world, Tasmania provides ideal conditions for growing fungi of exceptional quality. Because mushrooms absorb the environment around them, our location is central to the integrity and potency of the final product.
Every batch of Kingdom Five is grown in controlled conditions to ensure consistency, traceability, and safety. We use only the fruiting body — the part of the mushroom richest in active compounds like beta-glucans and polysaccharides. No mycelium. No grain filler. Just pure, bioactive material at its most potent form.
Through precision cultivation and uncompromising standards, we deliver the full potential of the Fifth Kingdom — refined for focus, immunity, and vitality.

Common Questions
What makes K5 different from other mushroom supplements?
K5 is a precisely formulated blend of five functional mushrooms, each chosen at a specific ratio for its clinically supported benefits to focus, immunity, and vitality. Unlike many mushroom supplements grown in unregulated conditions overseas — often in China — Kingdom 5 uses mushrooms cultivated in the clean, temperate environment of Tasmania, where air, soil, and water purity are carefully monitored. Mushrooms naturally absorb their surroundings, making growing conditions critical to safety and efficacy.
Unlike products that rely on mycelium grown on grain, Kingdom 5 contains 100% fruiting body extracts, the most nutrient-dense and bioactive part of the mushroom. Each batch is precisely balanced for synergistic effects and verified for beta-glucan content, ensuring measurable potency, transparency, and consistency in every serve. We can confidently say this is the purest source of mushrooms on the market.
Are your mushrooms 100% fruiting body?
Yes. Every mushroom used in Kingdom 5 is derived exclusively from the fruiting body, the part of the mushroom richest in beta-glucans, triterpenes, and polysaccharides — the key compounds responsible for their biological activity.
Unlike mycelium-based products, which are often grown on grain and diluted by starch, our fruiting bodies are grown and harvested in Tasmania under monitored environmental conditions, ensuring purity, traceability, and optimal potency.
Are there any fillers, additives, or preservatives?
No. Kingdom 5 contains no fillers, binders, additives, or preservatives — just pure, concentrated mushroom extracts. Each ingredient is carefully processed to preserve active compounds and tested for heavy metals and microbial contaminants.
What are the key benefits of Kingdom 5?
Kingdom 5 supports mental focus, immune function, and vitality through a scientifically balanced formulation of five functional mushrooms. Beta-glucans and antioxidants help modulate immune activity, while compounds such as hericenones and erinacines from Lion’s Mane support cognitive performance and clarity.
The product’s purity and full fruiting-body composition ensure high bioavailability of active compounds — allowing your body to benefit from the mushrooms’ natural adaptogenic and restorative effects.
How do I take Kingdom 5?
Mix one serve (approximately 1 gram) with water, coffee, smoothie or your preferred beverage. Consistency is key — daily use allows the body to build resilience and balance through cumulative adaptogenic effects.
How much should I take per day?
The recommended serving is 1 gram per day, based on research-supported dosages for functional mushroom extracts. This level provides an effective amount of beta-glucans and polysaccharides without over saturating the system.
However, different body size and individual tolerances do vary. We recommend starting at the recommended dose of 1 gram per day and adapting it if you feel the need.
Can I take Kingdom 5 every day?
Yes. K5 is designed for safe, daily use. Functional mushrooms are adaptogens — they work best when taken consistently to help the body adjust to stress, support immunity, and maintain equilibrium.
How long does delivery take?
All orders are processed within 1–3 business days and shipped from Tasmania using Australia Post or Sendle. Delivery typically takes 3–7 business days depending on your location.
Once dispatched, you’ll receive a tracking link for full transparency and updates on your order’s progress.
How does the subscription option work?
Our subscription service ensures you never run out of K5. You can choose a 30- or 60-day delivery schedule, and we’ll automatically send your next supply directly to your door.

Returns are accepted only in original packaging to maintain product integrity. Once received and inspected, refunds are processed promptly.
Are there any side effects?
K5 is packed with beta-glucans, polysaccharides, and natural detoxifiers, which work together to support your health. These powerful compounds may cause mild digestive changes for a small percentage of users, as your body adjusts.
Why It Happens
- Prebiotics for Gut Health:Mushrooms like Turkey Tail and Lion’s Mane are rich in prebiotic polysaccharides, which nourish beneficial gut bacteria. This gut microbiome shift may lead to temporary bloating or loose stools.
- Detoxification Effects: Reishi supports detox pathways with its triterpenes, which may cause your body to eliminate toxins, leading to mild digestive changes.
- Fiber and Chitin:Blue Oyster mushrooms contain chitin, a natural fiber that may initially be harder to digest but supports gut health long term.
How to Ease Into It
- Start Slowly: Begin with half a dose for the first 1-2 weeks.
- Take with Food: Eating with meals can buffer digestion.
- Stay Hydrated: Water helps your body process fibers and detoxifiers effectively.
Temporary but Beneficial
These adjustments are normal and typically subside within 1–2 weeks, leaving you energized, focused, and balanced.
