Top Shelf Mushrooms is an independent editorial publication. This page explains how we research and write content, how we handle commercial relationships, and what our disclosures mean.
How We Research
Every article on this site is grounded in published scientific literature. Our process:
- Primary sources first. We start with peer-reviewed studies accessed through PubMed, PubMed Central, and published journal databases — not secondary summaries or press releases about studies.
- Study type is always labeled. In vitro studies (cell cultures), animal model studies, and human clinical trials are explicitly identified in every article. These represent meaningfully different levels of evidence, and we treat them as such. Cell culture findings do not automatically translate to human outcomes. Animal findings require human validation before they can be considered relevant to supplementation decisions.
- Sample size and study quality are noted. A well-designed randomized controlled trial in 200 humans carries more weight than an open-label pilot study in 12. We note this where it matters.
- Ingredient evidence is distinguished from product evidence. Studies on lion’s mane extract tell us about the ingredient. They do not validate any specific commercial product. We maintain this distinction throughout.
- Null and mixed results are included. Research that fails to find an effect, or finds inconsistent effects, is part of the evidence base. We include it.
- Traditional use is contextualized, not inflated. Centuries of traditional use in East Asian medicine is legitimate historical context. It is not clinical validation. We note traditional use as cultural and historical background while keeping the evidentiary claims grounded in modern research.
Evidence Ratings We Use
Where relevant, articles use the following plain-language evidence descriptors:
- Strong human evidence: Multiple randomized controlled trials in humans with consistent findings
- Promising human evidence: Positive findings from human trials, but limited in number, size, or methodological quality
- Early-stage research: Findings primarily from animal models or cell cultures; human data limited or absent
- Traditional use only: Historical use documented; modern clinical research limited or absent
- Insufficient evidence: Claims made in marketing without identifiable scientific basis
Affiliate & Commercial Disclosures
Top Shelf Mushrooms features and promotes Pilly Labs mushroom supplement products. This is the primary commercial relationship on this site.
- Pilly Labs products are featured through banner advertising, editorial mentions, and contextual recommendations throughout the site.
- We do not run affiliate links to competing products.
- We do not publish negative comparative reviews of other brands.
- Where a specific product mention or recommendation appears, it will be accompanied by a disclosure statement identifying the commercial relationship.
- Pilly Labs is credited as the product formulator. Top Shelf Mushrooms is the content publisher. These are distinct roles and distinct entities.
Our commercial relationship with Pilly Labs does not change our evidence standards. When we describe Pilly Labs products, we accurately represent what the research on their ingredients shows — including the limitations of that research. We do not fabricate clinical outcomes, inflate benefit claims, or imply that ingredient-level research validates specific product efficacy.
