Fruiting body versus mycelium, extraction ratios, beta-glucan reporting and what a certificate of analysis actually tells you.
Methodology
A review of label practices and published analytical methods. No health outcomes are assessed.
What we evaluated
- Reishi
- Lion's mane
- Cordyceps
Criteria
- Plant part declared
- Extraction method and ratio
- Beta-glucan versus polysaccharide reporting
- Batch testing
Findings
- Polysaccharide content is often reported in place of beta-glucan, which inflates apparent potency.
- Few labels state the plant part used.
Limitations
This is a labelling and sourcing review, not a clinical assessment.
Recommendation
Require a batch certificate of analysis that reports beta-glucan specifically.
