Functional mushrooms are easy to buy and hard to buy well. The same name, lion's mane or reishi, can sit on a bottle of concentrated extract from the fruiting body or on a bag of ground grain with a little mycelium in it. Both are legal, both look similar, and the price difference does not always point the right way. Here are the seven things to check, in the order that matters most.
1. Fruiting body or mycelium
The fruiting body is the mushroom you would recognise in the forest. Mycelium is the root like network it grows from. Many cheap products are made by growing mycelium on rice or oats and then grinding the whole block, grain included. The result contains a lot of starch and comparatively little of the compounds people buy the mushroom for.
What to look for: the words fruiting body on the label, ideally 100 percent. Warning signs: mycelium, mycelium on grain, myceliated grain, or no information at all. If a product lists the mushroom under its Latin name but says nothing about the part used, ask.
2. Powder or extract, and the extract ratio
Mushroom powder is the dried mushroom, ground. It is honest and cheap, but mushroom cell walls are made of chitin, which the human gut breaks down poorly, so a large part passes through. An extract uses hot water, alcohol or both to pull the soluble compounds out and concentrate them.
The extract ratio tells you how much raw mushroom went into one unit of extract. A 12:1 extract means twelve kilograms of dried mushroom per kilogram of extract. Higher is not automatically better, because very high ratios can mean a narrow selection of compounds, but a product with no ratio at all leaves you guessing.
3. Double extraction
Mushrooms contain two main groups of compounds. Beta glucans are water soluble, triterpenes and compounds such as the hericenones of lion's mane are not. One solvent gets one group. Double extraction uses hot water first and alcohol second, then combines the two. For reishi, cordyceps, chaga and lion's mane this matters, which is why double extracted is now a search term of its own.
Two follow up questions: is the alcohol removed afterwards, and if not, how much remains? Alcohol free double extracts exist and suit children, pregnant women, people who avoid alcohol and anyone who takes drops several times a day.
4. Standardised content, and which number you are reading
Serious extracts state what they contain, usually as a percentage of polysaccharides or, more precisely, of beta glucans. The two are not the same. Polysaccharides can include starch from grain substrate, which is why a mycelium on grain product can show an impressive polysaccharide number. A beta glucan figure from a laboratory test is harder to fake. If a label says polysaccharides, ask for the beta glucan value.
5. No fillers, no flavourings
Read the ingredient list to the end. Maltodextrin, rice flour, dextrose and anti caking agents stretch the product. Capsules often need a flow agent, which is acceptable in small amounts but should be named. Instant mushroom coffees frequently contain more sugar, creamer or flavour than mushroom. The shorter the list, the better.
6. Origin, organic certification and lab tests
Mushrooms absorb what is around them, including heavy metals. Where the mushroom grew and how it was tested matters more than for most foods. Look for an organic certificate, a named country of origin, and a certificate of analysis for heavy metals, pesticides and moulds. A supplier who tests will show the results when asked. For chaga, wild harvested birch chaga from the north is the traditional source.
7. Form, dose and packaging
Drops, capsules, powder, tea or coffee: the right form is the one you will actually use every day. Whatever the form, the label should state the amount of extract per portion in milligrams and a daily dose. Light degrades active compounds, so dark or violet glass is a plus for liquid extracts. And check how many portions a pack really holds. A 100 ml bottle at 3 ml per day is about 33 days.
The checklist
- Fruiting body, stated on the label
- Extract, not just powder, with an extract ratio
- Double extracted, alcohol removed or amount stated
- Beta glucan or polysaccharide figure from a lab test
- No fillers, flavourings or sugar
- Origin, organic certificate and certificate of analysis
- Dose per portion in milligrams, portions per pack, light proof packaging
How Ra Hygge extracts are made
So that you can apply the list to us: Ra Hygge liquid extracts are made from 100 percent fruiting body, double extracted with hot water and alcohol, with the alcohol removed afterwards, at a ratio of 12:1 and standardised to 30 percent polysaccharides, in violet glass bottles of 100 ml, which is about 33 portions of 3 ml. There is a lion's mane extract, a reishi extract, a chaga extract, a cordyceps extract and a tremella extract, as well as a set of three. If you prefer powder, the extract collection also has 40 g powdered extracts. How to choose between the mushrooms is a separate question, which we answer in the article on which functional mushroom is right for you.
Frequently asked questions
Fruiting body or mycelium: which is better?
For the mushrooms sold as functional mushrooms, the fruiting body is the part that was traditionally used and that most studies looked at. Mycelium grown on grain is cheaper to produce and the powder contains a lot of the grain. If the label does not say fruiting body, assume mycelium.
What does double extracted mean?
The mushroom is extracted twice, once with hot water and once with alcohol, because the two groups of compounds dissolve in different solvents. Water takes the beta glucans, alcohol takes the triterpenes and similar compounds. A good double extract removes the alcohol afterwards or states clearly how much remains.
Is powder or extract better?
Powder is simply the dried, ground mushroom. An extract concentrates the soluble compounds and breaks open the chitin cell walls that humans digest poorly. Powder is cheaper per gram, extract is cheaper per useful portion. Compare the stated extract ratio and the dose per portion, not the price per pack.
How do I recognise a serious supplier?
They name the part of the mushroom, the extraction method, the extract ratio and the dose per portion, they can show a certificate of analysis for heavy metals, pesticides and moulds, and they do not promise cures. Vague wording such as proprietary blend or mushroom complex without amounts is a warning sign.
How much should a good mushroom extract cost?
Compare the price per daily portion, not per bottle or per gram. A 100 ml double extract at 3 ml per day lasts about a month, and a cheap powder that needs several grams a day can end up costing more for less. Ask what one portion delivers before you look at the price tag.
