Grass & Co


Suitable for Vegans


Grass & Co. Power Shiitake Mushroom supplement is a high-strength vegan formula which boosts energy and reduces fatigue with a blend of Shiitake mushrooms, Holy Basil, Iron, and Vitamins B9 and B12. 

Shiitake mushrooms are functional mushrooms, and when dried and powdered, the high volume of water they contain is absent, concentrating the beneficial nutrients they contain. People choose shiitake mushrooms as a supplement because they contain amino acids, B Vitamins, Vitamin D, and a range of trace elements, including iron, manganese, phosphorus, selenium, potassium, copper, and zinc. Shiitake also contains a unique polysaccharide known as lentinan. Shiitake’s benefits make it the perfect natural supplement to boost your energy levels and enhance your overall wellbeing.

Each flavourless Grass & Co. Power Shiitake Mushrooms energy boosting capsule contains 300mg of the full spectrum of the mushrooms' fruiting bodies (600mg per dose), including beta-glucan polysaccharides and antioxidants. This Shitake Mushroom supplement also contains Iron and B12, which contribute to normal energy-yielding metabolism, as well as folic acid, which reduces tiredness and fatigue.

Directions: As a food supplement, take one to two Shiitake mushroom capsules per day. Do not exceed two capsules per day. 

Not intended for use by persons under the age of 18 or if pregnant. Do not store in direct sunlight. Keep out of reach of children. Food supplements should not be used as a substitute for a varied diet and healthy lifestyle. May contain traces of peanuts.

What are functional mushroom supplements?
Functional mushrooms deliver a wide range of nutritional benefits and are rich in beta-d-glucan polysaccharides, triterpenoids, antioxidants, vitamins and amino acids.

Are these mushroom supplements the same as magic mushrooms?
No. Magic mushrooms contain psychoactive compounds, such as psilocybin that can produce hallucinations or altered states of consciousness. In contrast, functional mushrooms are daily supplements that may provide many health benefits.

Are mushroom supplements better than eating mushrooms?
Yes! You can eat some of the mushroom types used in the Grass&Co range. But, others, like chaga, are really tough and fibrous. However, functional mushroom supplements deliver more of the naturally potent nutritional benefits and are richer in beta-d-glucan polysaccharides, triterpenoids, antioxidants, vitamins and amino acids. Also, the process of extraction breaks down the chitin (a polysaccharide) in the cell walls which our bodies are not able to do. Therefore, our powerful mushroom supplements are more concentrated, bioavailable and convenient than edible mushrooms.

Are mushrooms legal?
Yes. Grass & Co. mushroom supplements are derived from 100% legal mushroom extracts sourced in Canada and made in the UK.

What’s unique about Grass & Co. Mushrooms?
Grass & Co only use 100% fruiting bodies. Mushroom supplements sourced from fruiting bodies rather than mycelium are richer in the beneficial bioactive compounds and nutrients that shoppers are looking for.  The cultivation of our Mushrooms is also vitally important in ensuring the purity of our extracts. Grass & Co source mushrooms grown on wood substrates as would happen in nature. There are no sterile laboratories or artificial lights. They are grown in greenhouses with natural lighting and fresh air flow. Naturally grown mushrooms offer the full spectrum of active compounds. They contain no additives, mycelium, grains or fillers and are non-GMO and gluten-free.

Can you stack or take more than one type of mushrooms every day?
Yes. We recommend taking no more than 1-2 of each type of Mushrooms Capsules per day e.g. FOCUS, RELAX, BIOME, POWER and DREAM.  Grass & Co. always recommend to ‘Start low and go slow.’ But, the total recommended limit is 2,000mg (or 2g) of mushroom extract powder per 24 hours. So, you can stack the capsules across the day as each Mushrooms offers its own distinctive nutritional profile. For example, you could take:

  • WAKING: BIOME 1 x Cap = 275mg (Chaga) AM:
  • FOCUS 2 x Caps = 600mg (Lion's Mane)
  • NOON: POWER 2 x Caps = 600mg (Shiitake) P
  • M: RELAX 1 x Cap = 250mg (Maitake BED:
  • DREAM 1 x Cap = 200mg (Reishi)

Do grass & co. Independently test mushrooms?  
Yes. And, just like our CBD, we openly share these Certificates of Analysis on our website product pages. This ensures that customers can be sure exactly how much of the mushrooms and their key components, such as beta-glucans they’re getting.

Are these mushroom supplements vegan?
Yes. The entire Grass & Co. range is vegan and cruelty-free.
