Key takeaways
- Look for the species’ Latin name and the part used: fruiting body or mycelium.
- Check whether it’s an extract, and how it was extracted.
- Read the full ingredients list, including any grain or additives.
- Treat percentages as meaningful only if you know how they were measured.
- Health promises and vague terms are warning signs.
A mushroom product label can tell you a great deal, if you know how to read it. It can also leave out a great deal. This guide walks through what a good label should show, what the terms mean, and the warning signs to watch for.
1. The species
Look for the Latin name as well as the common one: Hericium erinaceus, not just “Lion’s Mane”. Common names can be applied loosely, while the scientific name removes doubt. Be cautious of blends that list only “mushroom complex” without naming each species.
2. The part used
The label should say whether it contains the fruiting body, the mycelium or both. If you see “mycelium”, “myceliated” or “mycelial biomass”, check whether a grain such as rice or oats is also listed; it may make up a substantial part of the product. See Fruiting Body vs Mycelium.
3. The form and extraction
Is it an extract or simply dried mushroom? If extracted, how: hot water, alcohol or both? “Dual extract” usually means both. See What Does Dual Extract Mean?
4. The amount
The label should tell you how much you take per serving and, ideally, how much mushroom that represents. Extract ratios, such as 1:3, describe how much starting material went into the extract. See Understanding Mushroom Extract Ratios.
5. The full ingredients list
Everything in the product should be listed. For a tincture, that might be simply mushroom, water and alcohol. Watch for sweeteners, flavourings, fillers or flow agents, and consider whether they matter to you.
6. Figures and percentages
Some labels quote percentages of “polysaccharides” or “beta-glucans”. These can be useful, but only if you know how they were measured. A “polysaccharides” figure isn’t the same as a beta-glucan figure, and it can include starch. See Beta-Glucan Testing Explained.
7. The information required by law
In the UK, food supplements must carry certain information, including:
- the recommended daily amount, and a warning not to exceed it;
- a statement that food supplements should not be used as a substitute for a varied diet;
- a warning to keep the product out of the reach of young children;
- the name and address of the business responsible;
- a best-before date and a batch or lot number.
A label missing these basics is a red flag in itself.
Warning signs
- Health promises: claims to treat, cure or prevent disease, or specific health claims that aren’t authorised.
- Vague terms: “full spectrum”, “whole mushroom” or “proprietary blend” without explanation.
- No species or part named.
- Big numbers without context: very high percentages with no testing method stated.

When in doubt, ask
A good brand should be happy to answer questions about its species, sourcing, extraction and testing. If it can’t or won’t, that tells you something. Our guide How to Choose a Mushroom Extract brings all of this together.
Our labels
Every Spore & Bloom tincture names the species, uses fruiting bodies (and wild-harvested chaga), describes its dual extraction method and lists its full ingredients: mushroom, purified water and plant-derived ethanol. If there’s anything you’d like to know, get in touch.
