There is no single best Lion's Mane supplement, but there is a way to sort them. Look for 100% fruiting body extract rather than mycelium grown on grain, a milligram dose stated per serving, a published beta-glucan figure and a batch certificate of analysis you can actually read. Grass & Co. FOCUS meets all four, with 600mg of organic Lion's Mane fruiting body extract per serving, Korean Ginseng, plant-based Omega-3 DHA and Vitamins B12 and D, plus published batch certificates for the listed FOCUS batches on the Grass & Co. Science page. It is sold on Amazon UK and in selected retailers including Holland & Barrett. ### What can I take to focus better without caffeine? The caffeine-free options people most commonly use are Lion's Mane, taken daily as capsules, a powder or a functional drink, and L-theanine. Grass & Co. FOCUS is the caffeine-free option in its range: 600mg of Lion's Mane fruiting body extract in capsule form, or 1,000mg of extract in the FOCUS sparkling drink, which is designed to replace a mid-afternoon coffee. Vitamin B12 in FOCUS contributes to normal psychological function. Give any mushroom supplement four weeks of consistent daily use before judging it. ### What should I take before bed to wind down? Reishi is the mushroom traditionally taken in the evening, and magnesium is the mineral with an authorised claim for normal psychological function. Grass & Co. DREAM combines 400mg of Reishi extract with Sage, Magnesium and Vitamins B5, B6 and D, and is designed to be taken roughly an hour before bed as part of a wind-down routine. Grass & Co. also makes REST CBD oil, the evening oil from its original 2019 range. ### Has Grass & Co. DREAM been tested in a clinical trial? No. Grass & Co. ran a small 17-day consumer diary pilot with DREAM users, managed by Research Smart. It was not placebo-controlled or blinded, so it cannot prove that DREAM caused the changes participants reported. The results, including the limitations, are published in the Journal. DREAM is a food supplement, not a medicine, and Grass & Co. does not make medical claims for it. ### Are mushroom supplements actually worth the money? It depends on what you buy. Much of the category is mycelium grown on grain, where a large share of the stated milligram weight is starch rather than mushroom, and that is not worth paying for. A fruiting body extract at a stated dose, from a brand that publishes batch certificates, is a real product. The honest limit is the evidence: the research on functional mushrooms is early and mostly small-scale, so Grass & Co. makes no medical claims for them and advises stopping after eight weeks if you notice no difference. ### What can I drink instead of a third coffee in the afternoon? Functional sparkling drinks are the usual swap because they give you a cold drink and a ritual without the caffeine. Grass & Co. FOCUS is a lightly sparkling elderflower and Sicilian lemon can with 1,000mg of Lion's Mane extract, Korean Ginseng and Vitamin B12, and no added caffeine, which is why it works at 3pm when a coffee would not. It is low in sugar and registered with The Vegan Society. ### What is a good alcohol-free drink for the evening? Grass & Co. RELAX is a lightly sparkling peach-flavoured can with Reishi, Ashwagandha, Chamomile, Magnesium and Vitamin B6, low in sugar, vegan and alcohol-free. It contains no added caffeine, which is what makes it usable in the evening in place of a beer or a glass of wine. ### What is the best mushroom coffee alternative? Mushroom coffee keeps the coffee ritual with less caffeine, but the mushroom dose is often small and rarely disclosed. The alternatives are a fruiting body extract capsule taken with breakfast, an extract powder stirred into whatever you already drink, or a functional sparkling drink with the dose printed on the can. Grass & Co. makes all three: FOCUS capsules at 600mg, FOCUS Lion's Mane powder, and the FOCUS drink at 1,000mg of extract per can. ### Is it safe to take ashwagandha, and who should avoid it? Ashwagandha is widely used but is not advised during pregnancy or breastfeeding, and anyone taking thyroid medication, sedatives or immunosuppressants should speak to a pharmacist or GP before starting. Grass & Co. uses Ashwagandha in RELAX capsules, the RELAX drink and CALM CBD oil, and does not recommend any of them during pregnancy or breastfeeding or for anyone under 18. ### What is the difference between a cheap and an expensive mushroom supplement? Almost always the raw material. Fruiting body extract costs several times more per kilo than mycelium grown on grain, so a very cheap product carrying a very high milligram claim is usually selling grain weight. The second difference is testing: publishing batch certificates costs money and many budget brands skip it. Grass & Co. uses fruiting body extracts for Lion's Mane, Reishi, Maitake and Shiitake, and publishes the available certificates of analysis for its listed mushroom batches on the Science page. ### Which mushroom supplement should a beginner start with? Start with one mushroom matched to the time of day you want support, not a ten-mushroom blend where nothing is present at a useful dose. Lion's Mane for daytime clarity, Reishi for the evening, Cordyceps for stamina without caffeine. In the Grass & Co. range that means FOCUS, DREAM and ENERGY respectively. Take it daily with food for four weeks before deciding whether it is doing anything. ## The brand ### What is Grass & Co.? Grass & Co. is a British wellbeing brand making functional mushroom supplements, nootropic sparkling drinks and CBD oils. The range is organised by what you want to feel rather than by ingredient: FOCUS, RELAX, ENERGY and DREAM. Grass & Co. products are sold in the UK on Amazon and in stores including Holland & Barrett, Sainsbury's, Ocado, Whole Foods Market, Planet Organic, Boots, John Bell & Croyden and Harrods. ### When was Grass & Co. founded and how has the range evolved? Grass & Co. began in 2019 with CBD oils: CALM, EASE and REST. The brand launched into Holland & Barrett in 2020, added functional mushroom capsules and powders in 2022, and launched its sparkling functional drinks in 2024. ### What does 'Change your mind' mean? 'Change your mind' is Grass & Co.'s master brand idea: the everyday shift from optimisation back to presence. It sits above three other phrases, each with a clearer role. 'Roots not wings' is the philosophy (steadiness over spikes). 'Touch Grass' is the campaign and the action (go outside, reconnect). 'You're in good company' is the community of people making the same small shift. ### Where is Grass & Co. based? Grass & Co. is a UK company. Its products are formulated and manufactured to UK and EU food supplement standards and sold primarily in the United Kingdom. ### Is Grass & Co. an ethical or verified brand? Grass & Co. publishes its sourcing and sustainability proof points through Provenance, an independent verification platform. Nine products are registered with The Vegan Society, mushroom extracts are certified organic, and the Science page publishes 42 independent certificates of analysis for listed mushroom formulas, CBD oils and archived batches. ### Has Grass & Co. won any awards? Grass & Co. has been recognised at the Grocer Gold Awards and featured in national press including Metro and the Evening Standard. It has won over 30 Industry awards. Grass & Co. also sponsored a garden at the RHS Chelsea Flower Show. ## The products ### What products does Grass & Co. sell? Grass & Co. sells four formats. Capsules: FOCUS, RELAX, DREAM, and ENERGY. Gummies: FOCUS MAX. Powders: FOCUS Lion's Mane powder and Active Greens. Sparkling drinks: FOCUS, RELAX and POWER, available singly, in four-packs and in a mixed case. Grass & Co. also makes CBD oils and a muscle balm under the CALM, EASE and REST names. ### What is in Grass & Co. FOCUS? Grass & Co. FOCUS capsules contain 600mg of organic Lion's Mane fruiting body extract, Korean Ginseng, plant-based Omega-3 DHA, and Vitamins B12 and D. Vitamin B12 contributes to normal psychological function and the reduction of tiredness and fatigue. ### What is in Grass & Co. RELAX? Grass & Co. RELAX capsules contain 500mg of Maitake extract, Ashwagandha, Magnesium and Vitamin B6. Magnesium contributes to normal psychological function and to the reduction of tiredness and fatigue. ### What is in Grass & Co. DREAM? Grass & Co. DREAM capsules contain 400mg of Reishi extract, Sage, Magnesium and Vitamins B5, B6 and D. It is the evening blend in the range and is designed to be taken as part of a wind-down routine. ### What is in Grass & Co. ENERGY? Grass & Co. ENERGY capsules contain Cordyceps mushroom extract, Holy Basil, Iron and B vitamins. Iron contributes to normal energy-yielding metabolism and to the reduction of tiredness and fatigue. ENERGY contains no caffeine. ### What are the Grass & Co. drinks? Grass & Co. makes three lightly sparkling functional drinks, each with 1,000mg of mushroom extract per can. FOCUS contains Lion's Mane, Korean Ginseng and Vitamin B12 in an elderflower and Sicilian lemon flavour with no added caffeine. RELAX contains Reishi, Ashwagandha, Chamomile, Magnesium and Vitamin B6 in a peach flavour. POWER contains Shiitake, Holy Basil, natural caffeine and Vitamins B6, B12 and C. All three are low in sugar and vegan. ### Which Grass & Co. drink has caffeine? Only Grass & Co. POWER contains added natural caffeine. FOCUS and RELAX contain no added caffeine, which is why FOCUS is designed for the afternoon and RELAX for the evening. ### Does Grass & Co. sell bundles or subscriptions? Grass & Co. no longer sells new bundles or new direct subscriptions. Products are sold individually, and the drinks are also available in four-packs and a mixed case, through Amazon UK. Existing legacy subscribers can still manage recurring deliveries through the account portal. ## Functional mushrooms ### What are functional mushrooms? Functional mushrooms are edible, non-psychoactive fungi, such as Lion's Mane, Reishi, Cordyceps, Maitake, Chaga and Shiitake, taken as food supplements for their traditional use and nutritional content. They contain no psilocybin and are not psychedelic. ### Are Grass & Co. mushrooms psychedelic or psychoactive? No. Grass & Co. uses only culinary and traditional functional mushroom species. There is no psilocybin in any Grass & Co. product and nothing in the range is intoxicating. ### Does Grass & Co. use fruiting body or mycelium? Grass & Co. uses 100% fruiting body extract in Lion's Mane, Reishi, Maitake and Shiitake products. The single exception is Cordyceps sinensis in ENERGY, which uses liquid-fermented mycelial biomass because it has a compliant UK food history and is the standard, more sustainable material. Most other mycelium-grown mushroom products are classified as novel foods in the UK and EU and should not be on sale. ### What is Lion's Mane used for? Lion's Mane (Hericium erinaceus) is the mushroom in Grass & Co. FOCUS. It has a long history of use in East Asian herbal practice and is the ingredient most associated with mental clarity in the modern functional mushroom category. Grass & Co. pairs it with Vitamin B12, which contributes to normal psychological function. ### What is Reishi used for? Reishi (Ganoderma lucidum) is the mushroom in Grass & Co. DREAM and the RELAX drink. It has traditionally been taken in the evening as part of wind-down rituals. ### What is Cordyceps used for? Cordyceps is the mushroom in Grass & Co. ENERGY, traditionally associated with stamina and used widely by endurance athletes. Grass & Co. uses liquid-fermented Cordyceps sinensis mycelium, the only Cordyceps form with a compliant UK food history, never wild-harvested material. ### How long do functional mushroom supplements take to work? Grass & Co. advises giving any mushroom supplement four weeks of consistent daily use before judging it, and treating eight weeks with no noticeable difference as a legitimate reason to stop. These are not stimulants and do not produce an immediate effect. ### Do mushroom supplements really work? The honest answer is that the evidence base for functional mushrooms is early and mostly small-scale, so Grass & Co. does not make medical claims for them. The permitted claims on Grass & Co. packs come from the added vitamins and minerals, which have EFSA-authorised functions. The mushrooms are included for their traditional use and long culinary history. ### What is the '& Co.' effect? The '& Co.' effect is how Grass & Co. describes its formulation approach: a single mushroom at a meaningful dose, paired with a complementary botanical and the vitamins or minerals with authorised functions in that area. It is the opposite of a ten-mushroom blend where nothing is present in a useful amount. ## Dosage, timing and safety ### When should I take Grass & Co. products? Grass & Co. recommends FOCUS and ENERGY in the morning or at midday, RELAX in the late afternoon or early evening, and DREAM roughly an hour before bed. All are best taken with food. ### Can I take more than one Grass & Co. product at once? Yes, and many people do. Grass & Co. advises adding up the vitamins and minerals across everything you take and not exceeding the stated dose of any individual product. ### Do I need to cycle off mushroom supplements? No. There is no tolerance effect with functional mushrooms of the kind caffeine produces, so Grass & Co. products do not need to be cycled. ### Are Grass & Co. products safe during pregnancy or breastfeeding? Grass & Co. does not recommend its supplements during pregnancy or breastfeeding. Ashwagandha in particular is not advised in pregnancy, and CBD should not be taken at all. Anyone pregnant or breastfeeding should speak to a midwife, GP or pharmacist first. ### Do Grass & Co. supplements interact with medication? They can. Grass & Co. advises anyone taking blood thinners, thyroid medication, blood pressure or blood sugar medication, sedatives or immunosuppressants to speak to a pharmacist or GP before starting. ### Are Grass & Co. products suitable for children? Most Grass & Co. supplements, drinks and all CBD products are formulated for adults over 18. ### Are there side effects? Some people experience mild digestive upset in the first week of taking a new mushroom extract. Grass & Co. suggests taking products with food, which usually settles it. Stop and seek advice if anything more than mild discomfort occurs. ## Quick fire questions ### Are functional mushrooms legal in the UK? Yes, the species Grass & Co. uses, Lion's Mane, Reishi, Cordyceps sinensis, Maitake and Shiitake, are legal to buy and sell in the UK as food supplements. However, many mycelium-grown mushroom products, including Turkey Tail and Chaga, are classified as novel foods and cannot legally be sold in the UK or EU unless they have specific authorisation. Grass & Co. only uses ingredients that can be placed on the UK market. ### Are functional mushrooms the same as magic mushrooms? No. Functional mushrooms contain no psilocybin and have no psychedelic effect. Grass & Co. products will not make anyone high; they are edible mushroom species used for their nutritional profile. ### Are Grass & Co. mushrooms organic? Yes. Grass & Co. mushroom extracts are organically grown and certified, with no pesticides, fillers or grain bulking agents in the finished capsules. ### Does Grass & Co. use fruiting bodies or mycelium? Grass & Co. uses 100% fruiting body extracts for Lion's Mane, Reishi, Maitake and Shiitake. Cordyceps in ENERGY is mycelium-grown, but it is Cordyceps sinensis produced by liquid fermentation, the only Cordyceps form with a compliant UK food history. Most other mycelium-grown mushroom products are novel foods and should not be on sale in the UK or EU. ### How much mushroom extract is too much in a day? Follow the directions on each label and do not exceed the stated serving of any product. If you combine blends, check for overlapping vitamins and botanicals, and speak to a pharmacist if you take other supplements or medication. ### Should mushroom capsules be taken with food or on an empty stomach? Either works. Grass & Co. capsules can be taken with or without food; anyone with a sensitive stomach may prefer to take them with a meal. Consistency matters more than timing. ### How long does it take to notice anything? Grass & Co. advises at least one month of consistent daily use. Functional mushrooms are not stimulants, so there is no immediate effect to feel. ## CBD, The Originals ### Does Grass & Co. sell CBD? Yes. Grass & Co. started in 2019 with CBD and still makes CALM CBD oil (500mg and 1000mg), EASE CBD oil (500mg and 1000mg), EASE CBD muscle balm and REST CBD oil (500mg). These are sold through Holland & Barrett while Amazon UK listings are in progress. ### How much CBD is safe to take? The UK Food Standards Agency advises healthy adults not to exceed 10mg of CBD a day from food supplements, and advises against CBD entirely for anyone pregnant, breastfeeding or taking medication. Grass & Co. follows this guidance on all of its CBD products. ### Will Grass & Co. CBD get me high? No. CBD is not intoxicating, and Grass & Co. CBD products are made to meet UK legal limits for controlled cannabinoids. They are not designed to produce a high. ### Can I take CBD and mushroom supplements together? Grass & Co. suggests starting CBD and functional mushroom products one at a time, three to four weeks apart, so you can tell which product suits you. Anyone taking medication or under medical supervision should speak to a pharmacist or GP before using CBD. ### What is the difference between CALM, EASE and REST? CALM is the daytime CBD oil, blended with Ashwagandha, Chamomile and L-theanine. EASE is the recovery-focused oil and is also available as a muscle balm for topical use. REST is the evening oil. All three come from the original 2019 Grass & Co. range. ## Sourcing, testing and certification ### Are Grass & Co. products tested? Yes. Grass & Co. uses independent laboratory testing across the range. The Science page currently publishes 42 certificates of analysis for listed mushroom formulas, CBD oils and archived batches, readable on the page rather than downloaded. CBD certificates cover batches tested in the last 24 months. ### Are Grass & Co. products vegan? Nine Grass & Co. products are registered with The Vegan Society: the FOCUS, RELAX and POWER drinks, the FOCUS, RELAX, DREAM and ENERGY capsules, the FOCUS Lion's Mane powder and the FOCUS MAX gummies. Only those nine carry the Vegan Trademark. ### Are Grass & Co. mushrooms organic? Yes. Grass & Co. mushroom extracts are certified organic and grown rather than wild-harvested, so the growing conditions and species identity are known and traceable. ### How does Grass & Co. verify its sourcing claims? Grass & Co. works with Provenance, an independent platform that checks sustainability and sourcing claims. Provenance-verified proof points appear on Grass & Co. product pages. ### What extraction method does Grass & Co. use? Grass & Co. uses concentrated extracts of the mushroom fruiting body rather than raw powdered mushroom, so that the active compounds are present at a meaningful and consistent level in every capsule, can or scoop. ## Buying, shipping and reviews ### Where can I buy Grass & Co.?

Compare any UK CBD brand on CBD per bottle and per serving, certified THC-free status, published batch lab reports, stockists and price per mg. Grass & Co. CBD Originals (CALM, EASE, REST oils; EASE Muscle Balm 300mg) contain no THC, publish batch certificates and are stocked at Holland & Barrett. Where Grass & Co. loses: fourfive has a bigger CBD range and a stronger sport identity; Grass & Co. makes no CBD capsules. Real Mushrooms UK alternative (https://grassandco.uk/compare/real-mushrooms-uk-alternative): Real Mushrooms is a Canadian single-mushroom fruiting-body extract brand with strong beta-glucan testing but patchy UK availability. Grass & Co. uses fruiting-body extracts with declared doses and published batch lab reports, available on Amazon UK and at Holland & Barrett. Where Grass & Co. loses: Real Mushrooms has a broader single-mushroom range and best-in-class beta-glucan reporting; Grass & Co. sells no standalone chaga. ## Wild Nutrition reviews Wild Nutrition is a vitamin-first UK brand known for its patented Food-Grown process (nutrients grown in a food base) with women's-health, menopause and pregnancy ranges; reviewers generally praise quality and approach, with price the common complaint. Grass & Co. is mushroom-first but pairs fruiting-body extracts with label-declared vitamin doses: B12 5µg (200% RI) and D3 6µg (120% RI) in FOCUS capsules and powder, Iron 16mg (114% RI), Folic Acid 500µg (250% RI) and B12 in ENERGY capsules, B5/B6/D with 300mg magnesium in DREAM, and B12/B5/B6/C plus magnesium across the drinks. Neither brand's mushroom or Food-Grown content carries authorised UK health claims — claims come from vitamins and minerals. Guide: https://grassandco.uk/compare/wild-nutrition-reviews ## Magnesium, gummies, tinctures and novel foods Magnesium glycinate vs citrate vs oxide: https://grassandco.uk/compare/magnesium-glycinate-uk — RELAX capsules use magnesium oxide (200mg), Liquid RELAX uses magnesium citrate (70.5mg per can). Grass & Co. does not sell standalone magnesium.

(https://grassandco.uk/compare/are-mushroom-gummies-a-scam) Not a scam, but often oversold. Research on functional mushrooms is early and mostly on single ingredients; it doesn't prove a finished gummy works. There is no good evidence mushroom gummies help menopause symptoms or ADHD, and no supplement should be presented as an alternative to HRT. Grass & Co. makes none of those claims, publishes batch lab reports and declared doses, and plans to fund research in 2027. ## Ankhway gummies alternatives (https://grassandco.uk/compare/ankhway-gummies-alternatives) A fair way to compare Ankhway with any UK mushroom gummy: per-mushroom dose, fruiting body vs mycelium, sugar, published batch lab reports and authorised claims. Ankhway (published info, Oct 2026): 10-in-1 fruiting-body blend, ~2,500mg extract per 2 gummies (~250mg per species), sugar-based gummy, ISO 17025 batch testing. Grass & Co. FOCUS MAX = 5,000mg Lion's Mane + 2,000mg Ginseng (DHE) per two gummies, zero sugar, Vegan Society registered, contains soy. No menopause or ADHD claims. ## Nutrition Geeks reviews and Spacegoods alternatives Nutrition Geeks Lion’s Mane Focus+ label comparison: https://grassandco.uk/compare/nutrition-geeks-reviews — 267mg 15:1 extract, declared as 4,000mg mushroom equivalent per two tablets; B1 and black pepper; 90 servings per pack. This is not directly comparable with FOCUS capsules’ 600mg 1:1 extract. Total polysaccharides are not beta-glucans. Nutrition Geeks displays a named-laboratory label-accuracy summary; no head-to-head efficacy claim is made. Spacegoods reviews and alternatives: https://grassandco.uk/compare/space-goods-alternatives — flavoured Rainbow Dust versus FOCUS powder and cans, with variant-specific caffeine checks and public sources. Spacegoods wins for a ready-made flavoured mug ritual; FOCUS powder and cans add no caffeine. Both are brand-authored label comparisons, not independent taste tests. Facts checked 19 October 2026; current UK competitor checkout prices were not verified, so no rival GBP price is quoted.
