The best mushroom supplement is one whose label shows exactly what you’re getting: which mushroom (people choose lion’s mane for focus, reishi for evenings, cordyceps for exercise), the mg of extract per serving, fruiting body or mycelium, and a beta-glucan percentage. We checked UK labels in October 2026, and few state all four.
Below: where each format fits your day, how to read a label, what seven UK labels state (ours included), the research and safety.
Which mushroom product fits your routine?
We make one mushroom product: the Reishi Mushroom Adaptogenic Complex, a reishi hot chocolate. It’s reishi mushroom with cocoa, maca, coconut sugar. Stir 1 to 2 teaspoons (4 to 8g) into warm milk. It contains a little natural caffeine from the cacao.
To be straight with you: our label doesn’t yet state how much reishi is in each serving, the extract ratio, or whether it’s fruiting body or mycelium. We’ve asked for them to be added. Until then, judge it as a reishi hot chocolate, not a high-strength reishi supplement.
| When | Format | What to check | From us? |
|---|---|---|---|
| Evening | Reishi hot chocolate | Reishi per serving, sugar, a little caffeine | Reishi Cacao (ours) |
| Daytime | Lion’s mane or cordyceps capsules | mg of extract, fruiting body, beta-glucan % | We don’t make one |
| Morning | Mushroom coffee | Mushroom mg and caffeine per cup | We don’t make one; see mushroom coffee |
Comparing reishi drinks? See our mushroom hot chocolate guide. Alongside it, our Magnesium Glycinate Sleep Complex is a berry drink with 290mg of magnesium per serving (magnesium contributes to a reduction of tiredness and fatigue), and Flow CBD Oil is a daytime broad spectrum CBD oil with ashwagandha and maca.
Our pick
Reishi Mushroom Adaptogenic Complex
Reishi Cacao is a hot chocolate made with reishi mushroom, cacao and maca. It contains a little natural caffeine from the cacao, so it suits earlier in the evening.

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.
Value: a pouch is about 30 servings. We can’t give a price per mg of reishi until the amount is on our label. Subscribe and Save lowers the price of every order; skip, pause or cancel any time.

Best mushroom supplement by goal

How to choose: 7 things to check on the label
| Check | What good looks like |
|---|---|
| 1. Extract, not just ground powder | Mushroom cell walls are tough. Hot-water or dual extracts make the compounds easier to absorb |
| 2. Fruiting body | The label says “fruiting body”, or explains what part of the mushroom is used |
| 3. Beta-glucans listed | A percentage of beta-glucans, not just “polysaccharides”, which can include starch |
| 4. Clear dose | mg of each mushroom per serving, not a hidden “proprietary blend” |
| 5. Third-party testing | Tested for heavy metals and contaminants, with results you can see |
| 6. Short ingredients list | No unnecessary fillers, artificial sweeteners or flavourings |
| 7. Honest claims | No promises to cure, treat or “boost immunity”. Mushrooms have no authorised health claims in the UK |
UK mushroom supplements compared: what the labels state
Label facts from each brand’s own website, checked October 2026. Evopure isn’t connected with these brands, and we don’t rate them.
| Product | Mushroom per serving | Fruiting body? | Beta-glucans stated? |
|---|---|---|---|
| DIRTEA Mushroom Coffee | Lion’s mane 1,000mg | Yes | Yes: over 40% |
| Spacegoods Rainbow Dust | Lion’s mane, cordyceps, chaga: 1,000mg each | Yes | Not stated |
| Rheal Shroom Coffee | Lion’s mane 250mg | Not on the page we read | Not stated |
| Four Sigmatic Mushroom Coffee | Lion’s mane; amount not on the page we read | Yes | Not stated |
| Holland and Barrett Lion’s Mane capsules | 1,000mg of 20:1 extract (2 capsules) | Yes | No; 50% polysaccharides |
| Ankhway Mushroom Gummies | 10 mushrooms, 25mg of 10:1 extract each (2 gummies) | Yes | 48%, measured on the raw extract |
| Evopure Reishi Cacao | reishi mushroom; amount not stated yet | Not stated yet | Not stated yet |
Watch for “equivalent” figures: Ankhway’s 2,500mg is the dried-mushroom equivalent of 250mg of extract. See mushroom gummies for doses compared with the studies.
Fruiting body vs mycelium
The fruiting body is the mushroom you see above ground. Mycelium is the root-like network, and many cheaper products grow it on grain such as oats or rice. When the mycelium and grain are dried and ground together, much of the product can be starch from the grain. A 2025 lab study of chaga supplements found that products made from mycelium grown on grain were rich in starch, while the chaga mushroom itself contained none (the researchers work for a mushroom extract supplier, so read it with that in mind). That doesn’t make every mycelium product poor, but it’s why a stated beta-glucan content matters.
Powder, capsules or a drink?
| Format | Pros | Cons |
|---|---|---|
| Capsules | Tasteless, easy, exact dose | Lower amount per capsule |
| Powder | Flexible dose; stir into coffee, smoothies or porridge | Earthy taste |
| Drink blends (cacao, coffee, tea) | A ritual you’ll keep up; taste is taken care of | Check how much mushroom is in each serving |
| Tinctures | Quick to take | Often alcohol-based |
The best format is the one you’ll take every day. See how to make mushroom tea and mushroom coffee.
Do mushroom supplements work?
The honest answer is that the research is early. Most studies are small, use different extracts and doses, and many are in animals. Some human highlights:
- Lion’s mane: a Japanese trial in 30 older adults with mild memory problems found better cognitive scores after 16 weeks than placebo. A UK trial in young adults found small effects on speed and a trend towards lower stress.
- Reishi: in a trial of 132 adults with long-term fatigue, an extract improved fatigue and wellbeing more than placebo over 8 weeks.
- Cordyceps: small trials on exercise performance and recovery, with mixed results.
Give any mushroom supplement 4 to 8 weeks of daily use before deciding whether it suits you.
Side effects and who should avoid them
- Stomach upset is the most common side effect. Start with a smaller serving.
- Reishi: may slow blood clotting and lower blood pressure, so avoid it with blood thinners, with blood pressure medicines, or before surgery, unless your doctor agrees. Rare liver problems have been reported, usually with powders or alongside alcohol; the MSD Manual notes that taking powdered reishi for more than a month could damage the liver.
- Chaga: high in oxalates; avoid if you’ve had kidney stones or kidney problems.
- Lion’s mane: avoid if you’re allergic to mushrooms.
- Medicines: some mushrooms may lower blood sugar or blood pressure, so check with a pharmacist if you take medicines for either.
- Flow CBD Oil contains ashwagandha: avoid it if you have a thyroid, liver or autoimmune condition or are due to have surgery. See ashwagandha side effects.
- We don’t recommend our products during pregnancy or breastfeeding. They’re for adults (18+) only, and if you take any medication, check with your GP or pharmacist first.
