What We Test For
Understanding the key tests in a mushroom supplement Certificate of Analysis.
Beta-Glucan Content
Beta-glucans are the primary active compounds in functional mushrooms, responsible for immune modulation and other health benefits. Higher percentages indicate more potent extracts.
Heavy Metals
Tests for lead (Pb), arsenic (As), cadmium (Cd), and mercury (Hg). Mushrooms can accumulate heavy metals from their growing substrate. A "pass" means levels fall within safe limits established by USP and FDA guidelines. Look for actual ppm values for full transparency.
Microbial Testing
Screens for harmful bacteria (E. coli, Salmonella), yeast, and mold counts. This ensures the product is safe for consumption and was manufactured under proper sanitary conditions. Essential for any ingestible supplement.
Pesticide Residues
Multi-residue screening for hundreds of pesticide compounds. Organic-certified products should show no detectable pesticide residues. Even non-organic products should fall well within safety limits.
Potency Verification
Confirms that the active ingredient amounts match what's stated on the label. This ensures you're getting the dosage the brand promises, and that the extract is genuine mushroom fruiting body rather than filler or myceliated grain.
Identity Testing
DNA or chemical fingerprinting to confirm the mushroom species matches what's on the label. This prevents adulteration and ensures you're getting Lion's Mane, Reishi, or whichever species is claimed.
