Lab reports

Beta-Glucans 44.3%

1 of 6 - Potency

  • Why They Matter: Beta-D-glucans are the active compounds that give mushrooms their real health benefits.
  • Our Standard: We guarantee at least 40% beta-D-glucans—third-party tested for proven potency.
  • Watch Out: Terms like “high polysaccharides” can hide cheap starch fillers. Always look for beta-D-glucan levels.
  • True Transparency: Most brands rely on grain-based mycelium with minimal beta-D-glucans. We use only real mushroom fruiting bodies for maximum efficacy.

Get the potency you pay for—insist on tested beta-D-glucans.

Alpha-Glucans 6.66%

2 of 6 - Purity

Why This Matters

  • Alpha-Glucans as a Quality Check: High alpha-glucan levels can indicate fillers or impurities. At just 6.66.%, our Chaga stays remarkably pure.
  • Grain-Based Mycelium = Lower Quality: Many mushroom supplements use grain-based mycelium, resulting in inflated alpha-glucan content.
  • No Fillers, Pure Ingredients: Antioxi’s low alpha-glucan reading shows it’s free of grain fillers, ensuring higher integrity and potency.

Heavy Metals

3 of 6 - Safety

Why This Matters

  • Mushrooms Are Bio-Accumulators
    By nature, mushrooms can absorb heavy metals from their environment, making strict testing essential.
  • Stringent EU Standards
    The EU enforces some of the world’s toughest limits on lead, cadmium, and mercury. Our levels fall well below these limits for optimal safety.
  • Safe, Low Readings
    Even arsenic, which lacks a specific EU limit, remains at a low, non-hazardous level in our products.
  • Clean & Reliable Supplements
    By meeting and exceeding these standards, we guarantee you’re getting pure, high-quality supplements—free from harmful toxins.

Pesticides

3 of 7 - Safety

Why This Matters

  • Mushrooms Can Absorb Pesticides
    As natural bio-accumulators, mushrooms can store harmful chemicals from the environment, making thorough testing crucial.
  • Comprehensive Testing
    We use both Liquid Chromatography (LC) and Gas Chromatography (GC) to screen for pesticides, going beyond basic requirements to ensure your safety.
  • Below the Limit of Quantification
    Our third-party results show pesticide levels are too low to be measured—indicating practically none detected.
  • Your Assurance of Safety
    While some brands run minimal checks, we conduct full-spectrum screenings to deliver a clean, worry-free product.

Microbials

5 of 6 - Safety

Why This Matters

  • From Harvest to Home
    Mushrooms grow in natural environments and can pick up microbes at any point—during cultivation, transportation, or processing. That’s why we’re committed to stringent safety measures every step of the way.
  • High Standards, Pure Products
    By maintaining low microbial counts and ruling out harmful bacteria, we ensure our mushrooms are as safe and clean when they arrive at your door as they were at the source. This lets you enjoy every serving with total confidence.

Saccharomyces Cerevisae

6 of 6 - Purity

Why This Matters

  • Preventing Artificial Beta-Glucan Inflation
    Some brands use Baker’s Yeast (Saccharomyces cerevisiae) to falsely boost beta-glucan levels, creating misleading claims about potency.
  • Two-Tier Testing
    We check both regular yeast (DNA detectable, confirmed negative via PCR) and purified yeast (DNA undetectable, verified negative through microscopic analysis). This dual approach ensures zero yeast in our products.
  • True Mushroom Potency
    By ruling out yeast entirely, we protect the integrity of our extracts, so you know the beta-glucan content comes exclusively from real mushrooms. This way, you can trust you’re getting the true benefits you paid for.
The Antioxi Logo. The circle "o" in Antioxi's logo symbolizes completeness and ongoing commitment to quality, while the underline signifies a strong foundation, emphasizing our rigorous scientific and ethical standards.

Best Work

This is my go-to after meals now. I use it to support metabolism and digestion and it really does the trick. No bloating, and I feel lighter after eating.

Great Service

Shiitake isn’t as hyped as Lion’s Mane or Chaga, but I’m glad I gave it a try. My digestion feels smoother, and I’ve actually lost a little weight without changing much else.
