Back of Pack

Every product is priced by what is actually in it: pence per gram of mushroom extract, worked out from the label. Front-of-pack numbers are usually the raw mushroom a dose is equivalent to, not what is in the pack, so they are not used here.

Each row says when we last confirmed its price. A product sold by more than one shop appears once per shop, because they are different purchases at different prices, and we do not yet link them to each other.

A few packs state what a dose is equivalent to in raw mushroom, and the extraction ratio, but never how much extract is actually in them. Those are priced by dividing one by the other and marked Worked out, not stated, because the arithmetic is the brand’s and the figure is ours.

Comparable (68)

These labels say enough to price. Cheapest per gram of extract first. Tick any two or more and press Compare to put them side by side.

Priced, but not like for like (6)

The figure is real and the comparison would not be. A coffee with a token amount of mushroom in it is not a bad supplement, it is a different product, and ranking it against capsules would flatter the capsules for the wrong reason.

Cannot be compared (341)

Not a gap in the table. Each of these is a specific thing the label does not say, and that is worth knowing before you buy.

Quantity not published (170)

We read the label and it gives no figure at all for how much mushroom is in it.

Basis not stated (80)

The label gives a weight but never says whether it is extract or raw equivalent. Those differ by roughly ten times, so pricing it would mean guessing which.

Servings not disclosed (28)

The label gives a quantity per serving but never says how many servings are in the pack, so the pack cannot be priced.

Raw powder, not extract (25)

Sold as ground mushroom rather than a concentrated extract. A 10:1 extract is about ten times the strength by weight, so pricing the two on the same scale would make this look far worse value than it is.

Sold by weight, mushroom content not given (19)

The pack weight is printed, but not how much of it is mushroom. Common for lattes, coffees and blends, where mushroom is one ingredient among several.

Held while we check it (10)

This figure is so far out of line with every comparable product that we do not believe it. Usually that means we have misread the label. It is set aside until someone has looked, rather than shown to you as a price.

Only a front-of-pack figure (8)

The pack prints a headline figure but the label never says how much is in a serving, or whether that figure is extract or the raw mushroom it is equivalent to. Headline figures are usually the raw equivalent, so we do not price from them.

Raw equivalent only (1)

The label states what the extract is equivalent to in raw mushroom, but not how much extract is actually in it.

Tick products above, then compare them side by side.
