Coffee 2.0 review
Coffee 2.0 is a very complete mushroom coffee: 7 mushrooms, 18 ingredients and around 100 mg of caffeine per cup, as much as a regular coffee. It is a good choice if you want to keep all your caffeine. If, on the other hand, you are looking to cut down, Brainstoorm contains 20 mg, five times less, in a vegan recipe with no animal collagen. We compared the two labels line by line, using the actual doses of extract.
Who is writing: Mush n Go makes Brainstoorm, a direct competitor of Coffee 2.0. This page compares what each brand states on its website and, for Brainstoorm, the technical data sheet from our contract manufacturer. Figures recorded on 6 October 2026. We have no connection with Tasty Dose, the brand that sells Coffee 2.0.
Brainstoorm coffee flavour
Lion's mane, cordyceps and chaga from the fruiting body, maca, ashwagandha and roasted chicory. The taste of coffee, five times less caffeine.

Two good products, for two opposite needs.
Coffee 2.0 and Brainstoorm look alike on the shelf: a powder to stir in, mushrooms, plants. The difference comes down to one number: caffeine. Coffee 2.0 delivers as much as a coffee. Brainstoorm was designed to deliver five times less.
- Brainstoorm is for you if coffee makes you jittery or eats into your sleep, if you eat vegan, or if you like to know exactly what is in your cup: eleven ingredients, each with its dose.
- Coffee 2.0 is for you if you want as many mushrooms as possible, want to keep your usual dose of caffeine, and do not mind bovine collagen.
- On price, Coffee 2.0 is slightly cheaper as a one-off purchase (€1.33 per cup versus €1.42). Brainstoorm pulls ahead on subscription (€1.00, then €0.78 over 3 months).
What is Coffee 2.0
A powdered supplement, sold by Tasty Dose.
Coffee 2.0 is a powdered food supplement from the brand Tasty Dose, sold online in around twenty European countries. You prepare it like instant coffee: one spoonful in hot water or milk. The brand presents it as “one of the most powerful mushroom coffees in Europe” and claims more than 400,000 customers.
The ingredients in detail
What is in one serving of Coffee 2.0.
Tasty Dose states the dose of each ingredient and, for the mushrooms, the extraction ratio. That is a real plus: many brands settle for a “mushroom blend” with no figures. Here is the full breakdown.
| Ingredient | Stated dose | Ratio | Actual extract |
|---|---|---|---|
| Lion's mane | 4,000 mg | 5:1 | 800 mg |
| Tremella | 5,040 mg | 20:1 | 252 mg |
| Samsoniella hepiali | 2,000 mg | 10:1 | 200 mg |
| Shiitake | 1,000 mg | 4:1 | 250 mg |
| Maitake | 1,000 mg | 5:1 | 200 mg |
| Reishi | 1,000 mg | 10:1 | 100 mg |
| Cordyceps | 960 mg | 20:1 | 48 mg |
| Total 7 mushrooms | 15,000 mg | 1,850 mg | |
| Rhodiola | 1,000 mg | 10:1 | 100 mg |
| Maca | 250 mg | not stated | — |
| Ashwagandha | 160 mg | not stated | — |
| Guarana | 60 mg | of which 30 mg caffeine |

Reading the 15,000 mg
Mushroom equivalent or extract: the same product, two numbers.
Coffee 2.0 advertises 15,000 mg of mushrooms per cup. The brand specifies at the bottom of the page that this is a “mushroom equivalent, based on extraction ratios”. Brainstoorm states its doses in the same way. Here is how to read these numbers, ours as well as theirs.
An extract is a concentrate
A 10:1 extract means it took 10 g of dried mushroom to obtain 1 g of extract. The final powder weighs ten times less than the starting material.
The equivalent is the starting weight
When a label states “1,000 mg” with a 10:1 ratio, the cup contains 100 mg of extract. Both numbers are correct; they simply do not measure the same thing.
What to compare
Always the same column on both sides: extract against extract, or equivalent against equivalent. That is what the following table does.
The third useful number
The standardised content: the share of polysaccharides guaranteed in the extract. Brainstoorm's technical data sheet states it; the Coffee 2.0 page does not mention it.
Dosages compared
Brainstoorm and Coffee 2.0, line by line.
For each ingredient, the table gives the actual weight of extract and then, in brackets, the dried-plant equivalent shown on the label. The Brainstoorm figures are those of the coffee flavour, for a 6 g serving.
| Per cup | Brainstoorm coffee | Coffee 2.0 |
|---|---|---|
| Caffeine | 20 mg, microencapsulated | around 100 mg |
| Lion's mane | 100 mg (1,000 mg) | 800 mg (4,000 mg) |
| Cordyceps | 250 mg (1,000 mg) | 48 mg (960 mg) |
| Chaga | 20 mg (1,000 mg) | absent |
| Other mushrooms | none | 5 species, 1,002 mg (10,040 mg) |
| Maca | 375 mg (3,000 mg) | 250 mg, form not specified |
| Ashwagandha | 40 mg of extract | 160 mg, form not specified |
| Rhodiola | in the choc version (25 mg) | 100 mg (1,000 mg) |
| Fibre | chicory 3,500 mg, acacia 889 mg | inulin, amount not stated |
| Vitamin B5 | 6 mg, 100% of the reference intake | present, amount not stated |
| Collagen | none | 1,000 mg, bovine |
| Part of the mushroom | fruiting body | not specified |

Each recipe has its own logic. Coffee 2.0 bets on quantity: seven species, a generous dose of lion's mane, and the caffeine of a real coffee. Brainstoorm bets on balance: three selected mushrooms, five times more cordyceps extract, a good dose of maca, chaga, and five times less caffeine. Its vitamin B5, at 100% of the reference intake, contributes to the reduction of tiredness and fatigue and to normal mental performance.
Caffeine
100 mg on one side, 20 mg on the other.
This is the real dividing line. An espresso contains around 80 mg of caffeine according to the European Food Safety Authority. With around 100 mg per serving, Coffee 2.0 therefore drinks like a strong coffee, enriched with mushrooms. The brand says so itself: the product is not recommended for children, pregnant women or people sensitive to caffeine, and it advises against drinking it late in the evening.
Brainstoorm takes the opposite approach. Each cup contains 20 mg of NewCaff® microencapsulated caffeine, coated so that it is released gradually. The coffee taste comes from roasted chicory, which contains none.
One cup a day
Coffee 2.0: 100 mg. Brainstoorm: 20 mg. The EFSA benchmark for an adult is 400 mg a day, from all sources combined.
With your usual coffees
Two espressos plus one Coffee 2.0: around 260 mg. The same two espressos plus one Brainstoorm: around 180 mg.
In the afternoon
At 20 mg, a cup of Brainstoorm after lunch weighs four times less on your evening than an espresso.
If caffeine is what matters to you, our article how many cups of coffee a day does the maths cup by cup, and coffee and anxiety sets out the signs of having too much.
Vegan, sweeteners, flavours
What the ingredient list changes day to day.
Beyond the doses, three practical points separate the two recipes.
| Brainstoorm | Coffee 2.0 | |
|---|---|---|
| Vegan | yes, both flavours | no: bovine collagen, except Premium Dark Roast |
| Sweetener | xylitol | none (Café Classique), stevia (cocoa flavours) or sucralose (Caramel Salé, Iced Coffee) |
| Flavours | 2: coffee, choc-hazelnut | 8 |
| Number of ingredients | 11, each with its dose | 18, some of them without a stated dose |
| Manufacturing | France, Toulouse area | European Union |
Coffee 2.0 has the edge on choice: eight flavours, where Brainstoorm offers only two. Brainstoorm has the edge on simplicity: a short recipe, with no ingredients of animal origin, and the same mushrooms in both flavours.
Price, shipping, guarantee

Prices recorded on 6 October 2026 on mushngo.com and tastydose.com, France store, excluding temporary promotions. Coffee 2.0 includes four free gifts with the first order (frother, spoon, cup, samples).
As a one-off purchase, the two are within 9 cents of each other, in favour of Coffee 2.0, whose guarantee runs 30 days longer. If you drink your cup every day, the Brainstoorm subscription becomes the better deal: €1.00 per cup monthly, €0.78 over three months, with free shipping.
Which one to choose
Ask yourself just one question: how much caffeine do you want?
If the answer is “as much as before”, Coffee 2.0 is a serious product, transparent about its ratios, and you will not go wrong. If the answer is “less”, you are exactly the person we created Brainstoorm for: the taste and the ritual of a morning coffee, without the racing heart at 10 am or the slump at 3 pm.
- 20 mg of caffeine per cup, released gradually, to keep the ritual without the jitters.
- Three mushrooms from the fruiting body, 1,000 mg of equivalent each, with the dose of extract known for every line.
- 3,000 mg of maca equivalent and 6 mg of vitamin B5, which contributes to the reduction of tiredness and fatigue.
- Vegan recipe, with no animal collagen, made in France.
- No mushroom taste: roasted chicory brings the roundness and bitterness of a coffee.
- 60-day money-back guarantee: you taste, you decide.
More than 50,000 people have already replaced one of their cups with Brainstoorm, and rate it 4.8 out of 5.
Before starting either one
- Both products contain caffeine and are not recommended for children or for pregnant and breastfeeding women.
- Brainstoorm is not recommended if you have a thyroid, liver or heart condition: ask your doctor for advice.
- A food supplement is not a substitute for a varied diet. Do not exceed the stated daily dose.
