Grass & Co: CBD, Mushrooms and Ashwagandha Products Explained (UK)

What does Grass & Co. sell?

The range on grassandco.uk and Holland and Barrett on 23 October 2026:

Each mushroom product pairs one functional mushroom with herbs and vitamins. The CBD oils and balm are listed separately as “The Originals”.

Grass & Co. CBD oil: CALM, EASE and REST

All three are 10ml oils that mix CBD with botanicals and vitamins. Grass & Co.’s ingredient notes describe the hemp extract as broad spectrum, and the Holland and Barrett listings say the oils “contain no trace of THC”. Figures are from the Holland and Barrett labels.

• Grass & Co. CALM: CBD in MCT oil with ashwagandha extract (2.1mg per serving), chamomile extract, L-theanine, mint oils and vitamins B5, B6 and B12.
• Grass & Co. EASE oil: CBD in almond and olive oil with turmeric (3mg per serving) and ginger (2mg) extracts, L-theanine, orange oil and vitamins D and K2. It contains almond, so check it if you have a nut allergy.
• Grass & Co. REST: CBD in MCT and olive oil with lavender, hops extract, L-theanine, bergamot flavouring and B vitamins.

A “serving” on the label is two doses: 35mg of CBD on the 500mg oils and 70mg on the 1,000mg. If you’d rather skip to choosing one, our guide to the best CBD oils in the UK explains what we’d check first. In a 10ml bottle, the 500mg oils hold 50mg of CBD per ml and the 1,000mg 100mg per ml, so 10mg is about 0.2ml or 0.1ml. Grass & Co.’s CBD page quotes the FSA’s 10mg a day advice, and one of its comparison pages says the current CALM pack instruction is four drops. That is about 10mg on the 500mg bottle. Our CBD oil strengths guide has a drops chart for any brand, and the CBD daily limit in the UK explains the 10mg figure.

On the herbs: our guides to taking CBD and ashwagandha together and CBD and turmeric cover what’s known. Ashwagandha isn’t advised in pregnancy, and Grass & Co. says the same for its products.

Grass & Co. EASE CBD balm

The EASE CBD Muscle Balm is a 60ml pot with 300mg of CBD in a base of plant oils, scented with tea tree, eucalyptus, peppermint, camphor and arnica. Holland and Barrett lists it as vegan and THC free. It’s for skin, so the 10mg food advice doesn’t apply. Holland and Barrett also listed a GLOW 250mg CBD day cream. For how balms work and what to check, see our CBD balm guide.

Is Grass & Co. on the FSA list? Lab reports and THC

Yes. We downloaded the FSA’s public list of CBD products on 23 October 2026 and found six Grass and Co entries, all marked “Validated” under application RP-324: CALM 500mg and 1,000mg, EASE 500mg and 1,000mg, and REST 500mg and 1,000mg (the site currently sells REST in 500mg only).

Validated means the FSA has checked that the application has the information it needs to move on to a safety assessment. It isn’t an approval, but validated products can stay on sale in England and Wales while they are assessed. See what the FSA’s CBD decision means for buyers.

Grass & Co.’s Science page publishes 42 certificates of analysis, readable on the page. Nine cover the CBD oils, from Eurofins, the most recent dated July 2026, and test the full cannabinoid profile including THC. Grass & Co. says its certificates show no THC. The mushroom certificates (Eurofins and NLAB) report beta-glucans. To read any certificate yourself, see how to read CBD lab reports, and for the spectrum terms, full spectrum vs broad spectrum.

Where Evopure fits

Evopure is a separate UK company and isn’t connected with Grass & Co. Like the Originals, our oils blend CBD with plant extracts, which is still unusual in UK CBD:

• Flow CBD Oil: broad spectrum CBD with ashwagandha and maca, made for daytime.
• Sleep CBD Oil: broad spectrum CBD with passion flower and a terpene blend led by myrcene, for an evening routine.
• Relief CBD Oil: broad spectrum CBD with turmeric and black pepper extract.

All three come in 500mg and 1,000mg, are 0% THC and are on the FSA public list, linked to validated applications RP438, RP821 and RP47. They are vegan, made in the UK and tested by ISO 17025 accredited labs, with reports on request from our lab testing page. Our products are for adults (18+) only. We don’t recommend our products during pregnancy or breastfeeding.

The FSA’s 10mg a day figure is precautionary advice rather than a legal limit, set while longer-term safety research continues. At Evopure we think it is a very cautious figure, and many adults use more. If you go above it, increase slowly, and check with your GP or pharmacist first if you take any medication.

Grass & Co. DREAM, FOCUS, RELAX and ENERGY capsules

Each jar holds 60 vegan capsules, two per serving. Per serving, from grassandco.uk:

DREAM, FOCUS and RELAX use fruiting body extracts; ENERGY’s cordyceps is grown by liquid fermentation. Grass & Co. says DREAM hasn’t been through a clinical trial: it ran a 17-day consumer diary that wasn’t placebo-controlled. Its own FAQ calls mushroom research early and mostly small-scale. Our guides to reishi, lion’s mane, maitake and cordyceps go through the studies.

Grass & Co. drinks, gummies, powders and BOOST

• Liquid FOCUS: 250ml sparkling can with 1,000mg lion’s mane extract, ginseng and B12. Caffeine free.
• Liquid RELAX: 1,000mg reishi extract, 250mg ashwagandha extract, magnesium and B vitamins, peach and chamomile flavour.
• Liquid POWER: shiitake extract and 78mg of natural caffeine per can from guarana and coffee, labelled not for children or during pregnancy or breastfeeding.
• FOCUS MAX gummies: lion’s mane and ginseng, zero sugar; contains soy.
• FOCUS powder and ACTIVE greens: a 100g lion’s mane powder, and a 120g greens powder with lion’s mane, KSM-66 ashwagandha and maca.
• Grass & Co. BOOST: sold at Holland and Barrett, not on grassandco.uk’s shop page. A one-a-day “Sea Greens” capsule with 333mg algae omega-3, ginkgo, maca and CoQ10.

None of these contain CBD. For more on the formats, see mushroom gummies and CBD and functional drinks in the UK.

Where to buy Grass & Co.

Grass & Co. has closed its own online checkout. Its FAQ says the mushroom, drinks and powder range is sold through Amazon UK, and the CBD range through Holland and Barrett while Amazon listings are in progress. It also lists stockists including Sainsbury’s, Boots, Ocado and Whole Foods Market. Our guides to Holland and Barrett CBD and Boots CBD cover those shelves, and we’ve written similar fact checks on Love Hemp and Orange County CBD.

iIf you take medication, read can CBD interact with medication? CBD isn’t a treatment for anxiety, sleep problems, pain or any other condition. If something is affecting your daily life, see your GP.
