This Site Does Not Provide Medical Advice
Top Shelf Mushrooms is an independent editorial publication covering functional mushroom research and supplement education. The content on this site — including all articles, species guides, product reviews, and research summaries — is provided for informational and educational purposes only.
Nothing on this site constitutes medical advice, medical diagnosis, or treatment recommendations of any kind.
Reading this site does not create a patient-provider relationship, a client-practitioner relationship, or any professional relationship between you and Top Shelf Mushrooms, its editor Sage Mercer, or any contributor. We are not your healthcare provider.
Consult a Healthcare Professional
Before starting any supplement, changing any aspect of your healthcare routine, or making any decision related to your health, consult a qualified healthcare professional who knows your individual medical history, current medications, and specific health circumstances.
This is especially important if you:
- Take prescription medications — many supplements interact with medications, including blood thinners, immunosuppressants, diabetes medications, and others
- Have existing health conditions, including autoimmune conditions, kidney disease, liver disease, cardiovascular conditions, or immune disorders
- Are pregnant or nursing
- Are under 18 years of age
- Have upcoming surgery or a medical procedure
- Are being treated for cancer or any serious illness
FDA Disclaimer — Dietary Supplements
The dietary supplements discussed on this site are not FDA-approved drugs. They have not been evaluated by the Food and Drug Administration for safety, efficacy, or quality in the treatment, cure, diagnosis, or prevention of any disease or health condition.
These statements have not been evaluated by the Food and Drug Administration. These products are not intended to diagnose, treat, cure, or prevent any disease.
Research Presented on This Site
Where scientific research is cited on this site, the following apply:
- Study type matters. In vitro (cell culture) research, animal model research, and human clinical trials represent meaningfully different levels of evidence. Findings from one category do not automatically translate to another. We label study types throughout our content.
- Ingredient research ≠ product efficacy. Research findings on a mushroom species or compound describe the ingredient as studied in that research context — at a specific dose, preparation, and study population. They do not constitute evidence that any commercial supplement product containing that ingredient will produce the same outcomes.
- Individual variation is real. Responses to supplements vary significantly between individuals based on genetics, health status, diet, medications, and other factors. Research findings describe population-level averages, not guaranteed individual outcomes.
- Research evolves. Scientific understanding of functional mushrooms is actively developing. Information on this site reflects the research literature as understood at the time of writing and may be updated as new evidence emerges.

If you are experiencing a medical emergency, call 911 (in the US) or your local emergency services immediately. Do not use this website to seek guidance during a medical emergency. This site is not equipped to provide emergency assistance.
No Endorsement of Specific Medical Treatments
References to specific medical conditions, symptoms, or health goals on this site are for context and educational purposes only. They do not constitute a recommendation to pursue any particular treatment, supplement, or medical approach. All healthcare decisions should be made in consultation with a qualified provider.
