Lab reports

Beta-Glucan Content: 44.3%

Beta-D-glucans are a key indicator of mushroom supplement potency.

  • Why This Matters: Beta-D-glucans are studied for their potential immune-supporting properties. Measuring them helps gauge supplement quality.
  • Our Focus: We prioritize high beta-D-glucan levels. Grain-based mycelium products often lack these levels.
  • Little-Known Fact: Many brands don’t test for beta-D-glucan content, leading to inconsistent potency.
  • Our Standards: We test carefully for beta-D-glucans, recently raising our threshold from 30% to 40%.

Alpha-Glucan Content: 6.66%

Why This Matters:

  • Alpha-glucans can indicate impurities or fillers. A low alpha-glucan content of 6.66% confirms this product's purity.
  • Grain-based mycelium products often have higher alpha-glucan levels, signaling lower quality. Antioxi's low levels show no fillers or grains, ensuring higher product integrity.

Heavy Metals

Report vs EU Maximum Levels:

  • Lead, Cadmium, Mercury: All detected levels are well below the EU’s maximum limits, ensuring safety from these toxic metals.
  • Arsenic: No specific EU limit, but the detected level is low and considered safe.

Why This Matters:

  • Mushrooms can absorb harmful metals like lead and mercury.
  • The EU has some of the strictest limits globally, ensuring consumer protection.
  • We meet and exceed these safety standards to guarantee pure, safe supplements.

Pesticides

  • Tests Conducted: Liquid Chromatography (LC) and Gas Chromatography (GC) screenings.
  • Results: Pesticide levels were below the limit of quantification (<LOQ). This indicates that no detectable pesticide residues were found in the product.

Why This Matters:

  • Mushrooms can absorb pesticides, posing potential health risks.
  • We perform the most comprehensive pesticide tests, exceeding basic requirements for safety.
  • Many companies conduct only limited tests, but we ensure thorough screening for guaranteed product safety.

Microbials

  • Total Plate Count: Less than 10,000 CFU/g—meets safety standards.
  • Yeast and Mold: Below 100 CFU/g—low risk of contamination.
  • E. Coli and Salmonella: Both negative—no harmful pathogens detected.

Why This Matters:

  • Mushrooms can harbor microbes from their natural environment, making thorough testing essential to ensure a safe, contaminant-free product.

Saccharomyces cerevisiae

Saccharomyces cerevisiae (Baker's Yeast) can artificially inflate beta-glucan levels, misleading consumers about supplement potency.

Two Forms Tested
:

  • Regular: DNA detectable, confirmed negative through Polymerase Chain Reaction (PCR).
  • Purified: DNA undetectable, confirmed negative through Microscopic Analysis.

Why This Matters:

  • Testing for both forms ensures that no yeast is present, maintaining the integrity and true potency of our mushroom extracts. Beware, some companies use Saccharomyces cerevisiae to falsely boost beta-glucan levels.
