Pure and Certified Organic functional mushroom blend — Agaricus blazei, Lion's Mane and Reishi — grown in Portugal. Beta-glucans for growing immune systems. A curious mind that stays on. Calm resilience built from the ground up. For the whole family's long game.
What's in junior
Children's bodies are building everything — immune responses, neural connections, stress resilience, gut microbiome. The foundations laid now compound over time. Junior is Gribb's certified-organic functional mushroom blend designed to support that foundation with three of the most well-regarded mushrooms in traditional herbal practice: Agaricus blazei, Lion's Mane, and Reishi.
Each mushroom is chosen for its distinct profile of naturally occurring beta-glucans and bioactive compounds. Together they form a complementary trio that fits quietly and simply into a child's daily routine — flavour-neutral in powder form, invisible in a smoothie, yogurt, or warm milk. No strange tastes. No resistance. Just organic whole-fruiting-body mushrooms, grown by Gribb in Portugal, standardised to 32–40% beta-glucans (β1,3 / β1,6), and free of any fillers, mycelium on grain, or third-party sourcing.
Available as a fine powder or vegan HPMC capsules for older children and teens who prefer a capsule format. One product, two formats, every age from 3 upward — with paediatrician guidance always recommended before starting.
This product is a not a medicine. It is not intended to diagnose, treat, cure, or prevent any disease. Always consult a paediatrician or healthcare professional before introducing supplements to children, particularly for children under 6, those with health conditions, or those on medication.
the mushrooms
Agaricus blazei - Himematsutake · 33%
The Immune Foundation - Unusually high beta-glucan and proteoglycan content. One of the most studied mushrooms for innate immune support. Native to Brazil, beloved in Japanese wellness tradition as the "Sun Mushroom."
Lion's Mane - Hericium erinaceus · 33%
The Growing Mind - Contains hericenones and erinacines — compounds studied for their role in supporting nerve growth factor (NGF) and neural development. The functional mushroom most associated with brain and cognitive support.
Reishi - Ganoderma lucidum · 34%
The Calm Regulator - Triterpenoids (ganoderic acids) that modulate immune response and support stress adaptation. Known as the "mushroom of immortality" in Traditional Chinese Medicine. One of the highest beta-glucan concentrations of any edible mushroom.
Ideal for
- Your child seems to catch every bug going around — you want to support their immune system naturally
Agaricus blazei's beta-glucans and proteoglycans support the innate immune system — the first line of defence that children are still actively developing. - You're building healthy habits early — and you want supplements that support a growing mind
Lion's Mane contains hericenones and erinacines studied for their role in supporting nerve growth factor — a key compound in neural development during childhood and adolescence. - You want clean, organic ingredients you can actually trace — not a mystery capsule from a warehouse

Always consult a paediatrician or healthcare professional before introducing functional mushroom supplements to your child, particularly for children under 6, those with known health conditions, allergies, or those on medication. Dosage should be guided by your child's age, weight, health status, and individual needs. Do not exceed the recommended daily dose. Junior is a dietary supplement and part of a varied, balanced diet — not a substitute for medical care.
Natural health sources suggest functional mushrooms may be introduced from age 3, starting with the lowest dose and increasing gradually. The mushrooms in Junior — Agaricus blazei, Lion's Mane, and Reishi — are among those most commonly considered for children by integrative health practitioners.
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.

Why dual extraction matter
Most Lion's Mane 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
Gribb's Vitality Tincture is a certified-organic triple mushroom extract combining Chaga (Inonotus obliquus, 33%), Reishi (Ganoderma lucidum, 33%), and Shiitake (Lentinula edodes, 34%) — all whole fruiting body, grown in-house on Gribb's own farm in Portugal. T
he tincture uses a double extraction process — hot water for water-soluble beta-glucans and organic alcohol for fat-soluble compounds including triterpenoids — producing a full-spectrum extract standardised to 32–40% beta-glucans (β1,3 / β1,6). Each 1ml serving delivers 2,000mg of functional mushroom content.
The product contains 20–30% organic alcohol and spring water. Each 50ml bottle provides approximately 50 daily servings. Vegan. Certified organic PT-BIO-10. Flavour-neutral — suitable for sublingual use or added to any drink. Also available in powder and vegan HPMC capsule formats.
Natural health sources and integrative practitioners generally suggest that functional mushrooms like Agaricus blazei, Lion's Mane, and Reishi may be introduced from around age 3, starting with the lowest dose (half a small teaspoon of powder) and increasing gradually. That said, every child is different, and we always recommend consulting with a paediatrician or healthcare professional before introducing any supplement — especially for children under 6, those with health conditions, or those on medication. Junior is a food supplement, not a medicine.
The three mushrooms in Junior are chosen because their bioactive profiles are particularly well-suited to the areas most relevant to growing children. Agaricus blazei contains unusually high levels of beta-glucan proteoglycans that support the innate immune system — the first line of defence children are still developing. Lion's Mane contains hericenones and erinacines studied for their role in nerve growth factor (NGF), which supports neural development. Reishi's triterpenoids are among the most studied compounds for immune regulation and stress adaptation. Together they form a complementary trio rather than three versions of the same thing.
Yes — every mushroom in this kit 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.
Agaricus blazei, Lion's Mane, and Reishi are among the most widely used and well-studied functional mushrooms in traditional and integrative health practice, and are generally considered safe for children at appropriate doses when used as a food supplement. Junior contains no alcohol (unlike Gribb's tinctures), no synthetic additives, no mycelium on grain, and no fillers. We always recommend speaking with a paediatrician before introducing any supplement, particularly for younger children or those with specific health needs.
The powder is flavour-neutral — it has a very faint, earthy undertone at full concentration, but when added to a smoothie, yogurt, warm milk, or any flavoured drink, it becomes completely undetectable. Most parents find their children don't notice it at all. The capsule format is available for older children and teens who would prefer to take it that way.
Agaricus blazei — also known as "Cogumelo do Sol" in Brazil and "Himematsutake" in Japan — is an edible and medicinal mushroom with a long history in both Brazilian and Japanese wellness traditions. It contains unusually high levels of bioactive polysaccharides, particularly beta-glucans, and is one of the most studied functional mushrooms for immune support. It has a mild, pleasant, slightly almond-like flavour in its whole form, which fully disappears in powder extract.
The powder is the most versatile format — it mixes invisibly into any food or drink and is ideal for younger children who can't swallow capsules. The capsules (vegan HPMC, made from pine fibre) are better suited to older children and teenagers who prefer a straightforward capsule they can take with water. Both contain exactly the same mushroom blend at the same standardised beta-glucan content.
Each 60g pack provides approximately 30 servings at the full 2g adult dose. At the child dose (1g / half a teaspoon), a single pack provides approximately 60 servings — a two-month supply. At the age 6+ dose, expect 30–60 servings depending on exact dose used.
