Vital mushrooms – the 5 most important adaptogenic mushrooms in supplementation
Reishi, cordyceps, lion’s mane, chaga and shiitake – five mushrooms with a rich tradition in Eastern medicine, which have gained popularity in the global supplements market in recent decades. Find out about their botanical profiles, traditional uses, status in scientific research, and why communicating about them requires careful research framing.
The term ‘functional mushrooms’ (or ‘medicinal mushrooms’) refers to a group of higher fungi with a long tradition of use in Eastern medicine – primarily Traditional Chinese Medicine (TCM), Japanese Kampo and Tibetan medicine. Over the past two decades, functional mushrooms have been the subject of a growing body of scientific research, conducted mainly in Asia, Europe and North America. Nevertheless, under European regulations, none of them have health claims approved by the European Food Safety Authority – the scientific data are promising, but do not yet meet the rigorous criteria required for the approval of specific claims. For this reason, when communicating about vitality mushrooms, we focus on botanical descriptions, traditional uses and research findings, whilst exercising appropriate caution. This guide will present the five most important vitality mushrooms – reliably, without any marketing embellishment.
What are medicinal mushrooms and why are they being talked about?
Medicinal mushrooms are a group of higher fungi from various genera (Ganoderma, Cordyceps, Hericium, Inonotus, Lentinula, Grifola), which share a long tradition of use in Eastern medicine as ingredients in preparations designed to support the body’s general well-being. From a botanical perspective, they are organisms distinct from plants – fungi form their own kingdom (Fungi) with a specific profile of secondary metabolites.
The key bioactive compounds present in medicinal mushrooms are beta-glucans (specific polysaccharides with a complex structure), triterpenoids (found in certain fungi, e.g. reishi), polyphenols and B vitamins. The profile of these compounds varies significantly between different species, which influences their traditional uses.
Modern medicinal mushroom extracts can be prepared in various ways – most commonly from fruiting bodies (caps) or from mycelium. Standardisation for the content of specific beta-glucans is a key quality parameter – it significantly distinguishes between supplements made from comparable quantities of raw material. A reputable manufacturer provides transparent information on standardisation, the extraction method and the part of the mushroom used in production.
1. Reishi (Ganoderma lucidum) – the ‘mushroom of longevity’
Reishi is, without exaggeration, the most recognisable medicinal mushroom – known in Chinese tradition as ‘lingzhi’, and in Japanese as ‘reishi’ or ‘mannentake’. Its distinctive lacquered, reddish-brown cap has also made it a subject of Chinese decorative art.
Traditional use: in classical Chinese medicine, reishi was one of the most important ingredients in herbal preparations, used to support general vitality and the body’s adaptability. Traditionally intended for adults with demanding lifestyles.
Phytochemical profile: rich in triterpenoids (ganoderic acids), beta-glucans, peptidoglycans and sterols. The triterpenoid profile is a unique feature that distinguishes reishi from other medicinal mushrooms.
Research status: extensive scientific literature (mainly Chinese, Korean and Japanese), including clinical trials on humans. The EFSA has not approved any specific health claims – in our communications, we rely on descriptions of traditional use and the research framework.
Dosage: typically 400–1,200 mg of standardised fruiting body extract per day, divided into 1–2 doses. Traditionally, reishi is taken in the morning or evening as part of a long-term routine.
2. Cordyceps – the mushroom of energy and stamina
Cordyceps is a genus of parasitic fungi which, in the wild, grow on insects (mainly the larvae of butterflies of the genus Hepialus) in the high-altitude meadows of Tibet, Bhutan and Nepal. In Chinese medicine, it is known as ‘dong chong xia cao’ – literally ‘winter worm, summer grass’. Modern supplements usually contain cordyceps cultivated under controlled conditions (mainly Cordyceps militaris or Cordyceps sinensis).
Traditional use: in traditional Tibetan and Chinese medicine, cordyceps was one of the most highly prized fungi – traditionally recommended for people with demanding lifestyles, Tibetan athletes and adults seeking to maintain their general well-being.
Phytochemical profile: cordycepin, adenosine, polysaccharides, beta-glucans, sterols, amino acids. Cordycepin is a unique compound characteristic of this fungus.
Research status: extensive scientific literature, particularly regarding its potential impact on exercise performance. The EFSA has not authorised any specific claims. In our communications, we draw on tradition and the research framework.
Dosage: typically 500–1,500 mg of standardised extract per day. Cordyceps is traditionally taken in the morning or before training.
3. Lion’s Mane (Hericium erinaceus) – a mushroom for the brain and nerves
Lion’s Mane is a mushroom with a very distinctive appearance – white, drooping ‘spikes’ resembling a lion’s mane or a white hedgehog. Hence its English name ‘lion’s mane’ and the Polish name ‘soplówka’. It grows naturally on deciduous trees in Europe, Asia and North America.
Traditional uses: In Chinese and Japanese medicine, lion’s mane mushroom has traditionally been used as an ingredient in preparations intended for adults with demanding mental lifestyles. In Japanese tradition, it was also valued in cuisine – as an ingredient in exquisite dishes.
Phytochemical profile: hericenones, erinacins, beta-glucans, polyphenols. Hericenones and erinacins are compounds unique to Hericium erinaceus.
Research status: a growing body of scientific literature in recent years, particularly regarding its potential impact on cognitive function and the nervous system. The EFSA has not approved any specific health claims. Communication regarding traditional uses and research framing is cautious.
Dosage: typically 500–1,500 mg of standardised extract per day. Traditionally taken in the first half of the day.

4. Chaga (Inonotus obliquus) – “the diamond of the forest”
Chaga is a parasitic fungus that grows mainly on birch trunks in the forests of Siberia, Scandinavia, Canada and the northern United States. It has traditionally been valued in Siberian folk medicine, where it is known as the “diamond of the forest”. In Poland, it occurs naturally on birch trees in the northern and eastern forests.
Traditional use: in Siberian folk medicine, chaga was traditionally used in the form of infusions and decoctions, intended for adults leading a physically demanding lifestyle. This tradition dates back hundreds of years. It is also part of the herbal tradition in Scandinavian medicine.
Phytochemical profile: melanins, beta-glucans, betulinic acid (characteristic of birch trees), polyphenols, triterpenoids. Its high polyphenol content makes chaga one of the most antioxidant-rich medicinal mushrooms in laboratory analyses.
Research status: promising laboratory and clinical trial data, although most studies are still at a preliminary stage. The EFSA has not approved any specific claims. Communication focuses on tradition and research framing.
Dosage: typically 400–1,500 mg of standardised extract per day. Traditionally, chaga is taken in the form of infusions or aqueous extracts.
[Warning: Chaga contains oxalates – people with calcium oxalate kidney stones or kidney disease should exercise caution. Chaga may affect the absorption of certain medicines – if you are taking long-term medication (particularly anticoagulants and antidiabetics), consult your doctor before taking this supplement.]
5. Shiitake (Lentinula edodes) – a classic in cooking and supplementation
Shiitake is a mushroom known primarily as an ingredient in Japanese, Korean and Chinese cuisine – in Asia, it has been valued for over 2,000 years both for its culinary uses and as a component of herbal preparations. Today, shiitake is one of the most widely cultivated mushrooms in the world – second only to the button mushroom.
Tradition of use: in traditional Chinese and Japanese medicine, shiitake has traditionally been used in preparations designed to strengthen the general health of adults. Its unique status, bridging cuisine and traditional medicine, is characteristic – it is one of the mushrooms which, in Eastern tradition, has never been exclusively a ‘medicine’ or exclusively ‘food’.
Phytochemical profile: lentinan (a specific beta-glucan), eritadenine, ergosterol (a precursor of vitamin D2), amino acids. Lentinan is a unique beta-glucan that makes shiitake one of the most extensively studied medicinal mushrooms.
Research status: extensive scientific literature, particularly on lentinan and its biological mechanisms. Nevertheless, the EFSA has not approved specific health claims for shiitake as a supplement. Communication lies at the intersection of tradition and research framing.
Dosage: typically 400–1,500 mg of standardised extract per day. Fresh or dried shiitake mushrooms can also be eaten in their natural form – e.g. in Asian dishes.
Maitake and other complementary medicinal mushrooms
In addition to the five most commonly discussed medicinal mushrooms, it is worth mentioning maitake (Grifola frondosa), also known as the ‘dancing mushroom’ – traditionally used in Japanese cuisine and medicine. Maitake contains specific polysaccharides from the beta-glucan group, which are the subject of scientific research. Other mushrooms commonly found in supplements include turkey tail (Trametes versicolor), Agaricus blazei and the Brazilian mushroom – all of which have a tradition of use, but also lack approved EFSA claims.

Beta-glucans – why they are important and how to read labels
Beta-glucans are specific polysaccharides found in the cell walls of fungi (and certain cereals – e.g. oats). They are one of the main bioactive compounds responsible for the potential biological effects of vital fungi. From a consumer’s perspective, however, the most important thing is that the quality of the extract depends significantly on its beta-glucan content – and it is precisely this information that a reputable manufacturer should provide on the label.
Standardisation for beta-glucans (e.g. “extract standardised to a minimum of 30% beta-glucans”) is a concrete quality assurance. The absence of such information means that you do not know the actual content of active compounds in the preparation. Powdered fruiting bodies without standardisation may contain as little as a few per cent beta-glucans, whilst good-quality standardised extracts can reach 30–50 per cent.
The second parameter is the part of the mushroom used for extraction. The fruiting body (cap) usually contains higher concentrations of bioactive compounds than the mycelium grown on grain. Some cheaper preparations contain mainly grain with mycelium – which significantly reduces their actual value. A reputable manufacturer will clearly state whether the extract comes from the fruiting body, the mycelium, or both parts.
[tip: When reading the label of a medicinal mushroom product, check three key pieces of information: 1) standardisation for beta-glucans (percentage content), 2) the part of the mushroom used for extraction (fruiting body, mycelium, or both), 3) the type of extraction (aqueous, alcoholic, dual extract). The absence of this information means that the preparation may be significantly weaker than the ingredient weight on the label would suggest.]
When to consider medicinal mushrooms in your supplement regime
Medicinal mushrooms are ingredients primarily aimed at people who are consciously exploring the herbal traditions of Eastern medicine or who are interested in supplementation based on promising, though still preliminary, scientific research. Their place in a mindful supplementation routine is more as a ‘supplement’ than a ‘foundation’.
Vital mushrooms may be considered by:
People interested in the tradition of Eastern medicine – for whom vital mushrooms form a natural part of a broader approach based on herbs and supplements with a traditional history of use.
People who value the diversity of bioactive compounds – the profile of fungal polysaccharides is unique and distinct from typical vitamin, mineral or herbal supplements.
Adults seeking supplementation during periods of a demanding lifestyle – once the basics have been covered (EFSA-approved vitamins and minerals, Omega-3, and possibly basic adaptogens), medicinal mushrooms are often considered as an ‘advanced’ level of a mindful routine.
On the other hand, if the aim is to provide tangible support for specific areas of health with scientifically proven efficacy, it is advisable to prioritise ingredients with EFSA-approved health claims – vitamins, minerals and Omega-3. Vital mushrooms are an interesting area, but one still under investigation – the informed consumer makes a decision about supplementing with them with a full understanding of these limitations.
Comprehensive formulations – do “ ” “vital mushrooms combined” make sense?
Comprehensive formulations containing blends of several vital mushrooms in a single capsule are also available on the market. From a practical point of view, there are two sides to this.
Advantages: convenience (one preparation instead of several), a variety of bioactive compound profiles in a single formula, cost-effectiveness.
Disadvantages: lower doses of each individual mushroom, sometimes a lack of standardisation for specific compounds, difficulty in assessing ‘what works’.
A sensible approach for someone just getting to know medicinal mushrooms might be to start with a complex preparation – as an ‘introduction’ to this category. Once you have got into a routine and, if necessary, chosen specific mushrooms that best suit your individual needs, you can switch to single-ingredient preparations with higher doses of specific extracts.
[note: Vitaler’s offers all five key medicinal mushrooms in single-ingredient preparations (reishi, cordyceps, hedgehog mushroom, chaga, shiitake) as well as a comprehensive ‘Medicinal Mushrooms’ preparation. Each comes in a pure formula free from artificial colourings, preservatives or unnecessary fillers. The choice of a specific formula depends on your knowledge of vitality mushrooms and the stage of development of your supplementation routine.]
Safety and key situations requiring caution
[warning: Vital mushrooms are not recommended in the following situations: pregnancy and breastfeeding (insufficient safety data available), under the age of 18, autoimmune conditions (mushrooms may affect the immune system in unpredictable ways in these individuals), planned or recent surgery (some mushrooms may affect blood clotting – allow at least a 2-week interval before and after surgery). Before starting supplementation, consult your doctor if you are taking anticoagulants (warfarin, NOACs), immunosuppressants, antidiabetic medicines or medicines for high blood pressure – interactions are possible. Reishi may affect the action of anticoagulants. Chaga contains oxalates – contraindicated in cases of oxalate kidney stones. Cordyceps may affect glucose levels – people with diabetes must exercise particular caution. People with an allergy to mould fungi or who are allergic to specific species of fungi – check your individual tolerance.]
FAQ – frequently asked questions about medicinal mushrooms
How long can medicinal mushrooms be taken for
The traditional approach in Eastern medicine favours long-term, regular use rather than short courses of treatment. Contemporary practice recommends cyclical use – 2–3 months of supplementation, followed by a break of several weeks. The long-term safety of continuous use has not been sufficiently studied in a European context.
Can different medicinal mushrooms be combined
From the perspective of traditional Eastern medicine – yes, combining medicinal mushrooms is a common practice (the ‘10 mushrooms’ preparation is a classic of Chinese cuisine and medicine). From the perspective of modern supplementation – if you are taking a complex preparation, it is not advisable to add single-ingredient mushrooms (the total dose may be excessive). Combining two single-ingredient mushrooms (e.g. reishi in the morning + cordyceps before training) is well tolerated.
Can medicinal mushrooms replace traditional adaptogens such as ginseng or ashwagandha?
Medicinal mushrooms and traditional adaptogens (ashwagandha, ginseng, maca, rhodiola) are different categories of ingredients with distinct profiles of bioactive compounds. They can complement each other well, but are not necessarily interchangeable. A well-informed supplementation routine can combine both categories – in moderation and following medical advice when using multiple adaptogens simultaneously over the long term. You can find out more in the articles on Korean ginseng and Chinese magnolia vine (schisandra).
Are medicinal mushrooms in capsule form just as beneficial as fresh shiitake mushrooms in food
Fresh mushrooms consumed as part of the diet (such as shiitake in Asian dishes or maitake in Japanese cuisine) provide bioactive compounds in smaller but regularly repeated doses – in combination with other food ingredients. Capsule supplements containing standardised extracts provide significantly higher concentrations of specific compounds. These are two different approaches – both have their merits. The most effective strategy combines both: fresh mushrooms in the diet + supplementation with standardised extracts of specific mushrooms. Find out more about making informed decisions on supplementation in the article how to read a dietary supplement label.
Summary: Vital mushrooms comprise a group of the five most commonly discussed mushrooms – reishi, cordyceps, hedgehog mushroom, chaga and shiitake – which have a rich tradition of use in Eastern medicine (primarily Chinese, Japanese and Siberian). Their profile of bioactive compounds (beta-glucans, triterpenoids, polyphenols, peptidoglycans) is unique and distinct from that of typical vitamin and mineral supplements or herbal extracts. Despite the growing body of scientific research, medicinal mushrooms do not have health claims approved by the EFSA – when communicating about them, we focus on tradition and research findings, whilst exercising appropriate caution. When choosing a supplement containing vital mushrooms, look for standardisation for beta-glucans, the part of the mushroom used for extraction, and the manufacturer’s transparency. These products are aimed at informed consumers who are aware of their research status and make well-considered decisions – as a complement to a mindful routine based on products with EFSA-approved health claims.
