Safety
Safety & Cautions
May increase bleeding risk when combined with anticoagulants, antiplatelets, or aspirin, and can oppose immunosuppressant medications used post transplant or for autoimmune disease. Existing liver disease is a caution requiring medical supervision; rare liver enzyme elevation has been reported mainly at very high, prolonged doses.
High caution
Caution level: High. Multiple caution categories apply, or the record uses avoid/contraindication language.
- Liver-SensitiveLiver-related caution language appears in the profile.
- Anticoagulant CautionBleeding or anticoagulant-adjacent caution language is present.

Full safety note
- May increase bleeding risk when combined with anticoagulants, antiplatelets, or aspirin, and can oppose immunosuppressant medications used post transplant or for autoimmune disease. Existing liver disease is a caution requiring medical supervision; rare liver enzyme elevation has been reported mainly at very high, prolonged doses. Mild dizziness, GI upset, or skin irritation are the most common side effects.

Caution when combined
Severity and certainty are shown separately. A high-priority caution can still be theoretical: these pairings are screened from shared contraindication mechanisms and are not automatically documented clinical interactions. Provenance identifies the source fields that produced each flag; it does not upgrade the certainty of the pairwise claim.

How evidence grades work
Each grade reflects the strength and consistency of published human evidence — not marketing claims. Grades are based on study count, design quality, effect size, consistency, and recency.
- Strong
- Multiple RCTs, consistent direction, adequate effect size
- Moderate
- Some RCTs or consistent observational data in humans
- Preliminary / Mixed
- Animal or in-vitro only, or conflicting human data
- Traditional / Theoretical
- Traditional use only; no controlled human trials

Product form & quality guidelines
When sourcing Reishi Ganoderma Lucidum, verify the label for:
- Standardized extract: Confirm active content percentages on the supplement facts panel (e.g. standardized to specific marker compounds) rather than simple raw herb weights.
- Third-party testing: Look for independent purity labels (USP, NSF, ConsumerLab, or Eurofins) to ensure the product is free from heavy metals, solvents, and contaminants.
- Form bioavailability: Ensure the form matches evidence-supported configurations (e.g. standardized active extracts like bacosides, withanolides, or curcuminoids) for optimal onset and digestion tolerance.
