Pure and Certified Organic four-mushroom beauty blend — Tremella, Chaga, Maitake and Reishi, grown in Portugal. Deep cellular hydration. Antioxidant armour. Collagen support from within. The Radiance formula in your morning smoothie.
For skin radiance from within — four beauty mushrooms.
What's in radiance
Radiance Blend brings together four certified-organic functional mushrooms — each with a distinct, research-backed role in skin health — in a 10:1 concentrated extract powder and capsule format: Tremella (Tremella fuciformis), whose polysaccharides retain up to 500 times their weight in water and support collagen I, elastin, and hyaluronic acid production in skin fibroblasts; Chaga (Inonotus obliquus), which carries the highest polyphenol and antioxidant density of any studied functional mushroom; Maitake (Grifola frondosa), shown in research to have the strongest flavonoid content and antioxidant activity among Reishi, Lion's Mane and Maitake tested head-to-head; and Reishi (Ganoderma lucidum), whose triterpenoids reduce skin inflammation and protect the barrier from oxidative stress.
All four mushrooms are grown in-house on Gribb's certified-organic farm in Portugal, concentrated to a 10:1 ratio — each 2,000mg serving equivalent to 20,000mg fresh fruiting body — and standardised to 32–40% beta-glucans (β1,3 / β1,6); available as a fine unflavoured powder or vegan HPMC capsules (pine fibre).

the mushrooms
Tremella fuciformis · 25%
The Hydrator - Polysaccharides retain 500× their weight in water. Supports collagen I, elastin & hyaluronic acid in skin fibroblasts. More hydrating than hyaluronic acid — and deeper penetrating.
Chaga - Inonotus obliquus · 25%
The Shield - Highest polyphenol content of any studied functional mushroom. Betulinic acid & melanin pigments neutralise free radicals and protect skin cells from oxidative ageing.
Maitake - Grifola frondosa · 25%
The Brightener - Highest flavonoid & antioxidant activity of Reishi, Lion's Mane & Maitake in head-to-head research. Polysaccharides support collagen synthesis and inhibit melanogenesis for even skin tone.
Reishi - Ganoderma lucidum · 25%
The Regulator - Triterpenoids (ganoderic acids) reduce skin inflammation and protect the barrier from environmental stressors. Anti-aging properties studied in dermatology and cosmetics research.

Ideal for
- Your skin is dehydrated from the inside — and no topical product is reaching it Tremella polysaccharides work systemically — supporting collagen, elastin, and hyaluronic acid production in skin fibroblasts with a water-retention capacity of up to 500× their weight. The hydration that starts in a scoop, not a serum.
- Dullness, uneven skin tone, free radical damage — you want to address the source Chaga's polyphenols and Maitake's flavonoids — the two highest antioxidant-density mushrooms in functional mushroom research — neutralise oxidative stress at the cellular level. Maitake also inhibits melanogenesis, the process behind dark spots and uneven tone.
- You've done collagen supplements — now you want the blend that supports your body's own production Tremella, Maitake, and Reishi all contain research-backed compounds that support collagen synthesis pathways from within — not supplemented collagen, but your own fibroblast activity, stimulated naturally by four mushrooms working simultaneously.

How to use
Powder — add 1 level tsp (2g) to any smoothie, drink, or warm beverage. Flavour-neutral — blends invisibly.
Capsules — take 2 capsules (2,000mg) daily with a glass of water. Any time of day, with or without food.
Best taken consistently as part of a daily routine. Most people notice changes in skin hydration, texture, and radiance after 3–4 weeks of consistent use. One pack = 30 days.
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 Radiance Blend is a certified-organic four-mushroom beauty supplement in powder and capsule format, combining Chaga — Inonotus obliquus (25%), Maitake — Grifola frondosa (25%), Tremella — Tremella fuciformis (25%), and Reishi — Ganoderma lucidum (25%).
All mushrooms grown in-house on Gribb's certified-organic farm in Portugal under PT-BIO-10. 10:1 concentrated extract — each 2,000mg serving equivalent to 20,000mg fresh fruiting body. Beta-glucans standardised 32–40% (β1,3/β1,6). Available as 60g fine powder (30 servings) or 60 × 1,000mg vegan HPMC capsules (pine fibre, 30 servings). Tremella polysaccharides studied for 500× water retention, collagen and hyaluronic acid support in skin fibroblasts. Chaga carries highest polyphenol density of studied functional mushrooms. Maitake shows strongest flavonoid and antioxidant activity in head-to-head comparisons. Reishi triterpenoids reduce skin inflammation and protect barrier from oxidative stress.
Vegan. No known allergens. Facility handles nuts, peanuts, sesame seeds, gluten, soy
Because they cover four distinct and complementary mechanisms of skin health simultaneously. Tremella hydrates at the cellular level — its polysaccharides retain up to 500 times their weight in water and support collagen and hyaluronic acid production in skin fibroblasts. Chaga provides the highest antioxidant density of any studied functional mushroom, neutralising the free radical damage that accelerates skin ageing.
Maitake has been shown in head-to-head research to have the strongest flavonoid content and antioxidant activity compared to Reishi and Lion's Mane — and its compounds inhibit melanogenesis for a more even complexion. Reishi's triterpenoids reduce skin inflammation and protect the barrier from environmental stress. No single mushroom delivers all four simultaneously. The blend does.
It means 10kg of fresh mushroom fruiting body is concentrated to produce 1kg of extract powder — for each of the four mushrooms in this blend. A 2g serving of Radiance Blend therefore delivers the bioactive equivalent of 20g of fresh mushroom. Combined with standardisation to 32–40% beta-glucans, it ensures that every dose is genuinely potent — not just labelled with impressive mushroom names at trace amounts.
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.
No — Radiance Blend powder is formulated to be flavour-neutral. At a standard 2g dose it blends invisibly into smoothies, matcha, oat milk, or warm drinks. In water alone you may notice a very mild, faintly earthy note at full concentration, but in any flavoured drink it is undetectable. It is one of the cleanest-tasting multi-mushroom powders available for exactly this reason.
Collagen supplements provide exogenous collagen that your body must break down and reassemble — with uncertain absorption efficiency. The mushrooms in Radiance Blend — particularly Tremella, Maitake, and Reishi — contain bioactive compounds that support your own collagen synthesis pathways from within: supporting fibroblast activity and reducing the oxidative stress that degrades existing collagen. They also address skin hydration, free radical damage, and inflammation simultaneously — things a collagen supplement alone cannot reach.
Yes. Every mushroom used in Gribb's Lion's Mane tincture is grown on Gribb's own certified-organic farm in Portugal — certified under PT-BIO-10. No third-party mushrooms are ever used, which means full traceability from spore to bottle. Every batch is lab-tested for beta-glucan content and purity before it leaves the farm.
