What are functional mushrooms?

Functional mushrooms are a category of non-psychoactive, bioactive fungi that offer a range of health benefits beyond basic nutrition. Unlike culinary mushrooms used primarily for flavour, functional mushrooms are valued for their rich profile of polysaccharides (especially beta-glucans), antioxidants, triterpenoids, and other unique compounds that contribute to immune modulation, cognitive support, stress resilience, and cellular protection.

Everything you need to know about our capsules, gummies and orders.

FAQs

All our products are 100% plant-based and free from animal-derived ingredients. We use vegan capsules (no gelatine), and our gummy supplements contain no honey or animal-based gelling agents. On top of that, we are proud to hold an official Halal certification, so you can feel confident knowing our products meet the required standards.

Functional mushrooms like reishi, lion’s mane have been used for centuries to support energy, focus, immunity, and stress balance. Our blends combine these mushrooms in science-backed ratios to help you feel your best, naturally.

With anything natural, results come with consistency. Mushrooms work gently and build over time. Some people notice sharper focus or calmer sleep within days; for others it’s weeks. Think of them as long-term allies for your well-being. But consistency is key! Suggested Use: Take 1–2 capsules daily with water, preferably with food, or as directed by a healthcare professional. Chew 1-2 gummies anytime of the day. Important Information: Do not exceed the recommended daily dose. Food supplements should not be used as a substitute for a varied and balanced diet or healthy lifestyle. If you are pregnant, breastfeeding, taking any medication, or have a medical condition, please consult a healthcare professional before use. Keep out of reach of children. Store in a cool, dry place away from direct sunlight.

Our products are free from gluten, soy, dairy, and common allergens. However, they are produced in facilities that may handle other ingredients. This product is not suitable for people with mushroom allergy.

We’re not just selling capsules in a jar. Every bottle is designed as a gift - to yourself or someone you love. Our mushrooms are organic, water-extracted, fruiting-body based, and packed in unique matte-green bottles with gold accents. It’s quality you can see, feel, and trust.
