Independent Tests Confirm Antioxi Mushroom Extracts Are Free from Saccharomyces cerevisiae (Baker's Yeast)

Recent allegations have surfaced on social media questioning the integrity of Antioxi's mushroom extracts, specifically accusing us of adding Saccharomyces cerevisiae to inflate the beta-glucan content of our products. We strongly refute these claims and have partnered with Helix Biological Laboratory and Alkemist Labs to conduct an independent analysis. The results confirm unequivocally that our products are free from Saccharomyces cerevisiae, affirming their purity and the reliability of our lab tests.

Introduction to the Controversy
In recent weeks, a narrative has emerged on social media platforms where competitors have cast doubt on the authenticity of Antioxi’s mushroom extract powders. These allegations suggested that we had deliberately added Saccharomyces cerevisiae extract to our products to artificially enhance the beta-glucan percentages reported in our lab tests. Understanding the potential impact of these claims on consumer trust, we felt it imperative to address these accusations head-on.

What is Saccharomyces cerevisiae?
Saccharomyces cerevisiae is a species of yeast commonly used in baking, brewing, and wine-making. It is known for its role in fermentation, causing dough to rise and sugar to convert into alcohol. In scientific contexts, this yeast is also used to study cell biology and genetics.

Regular Saccharomyces cerevisiae vs. Purified Saccharomyces cerevisiae
Regular Saccharomyces cerevisiae is composed of intact, viable cells containing all cellular components, including DNA, and is used for fermentation and nutritional purposes. In regular Saccharomyces cerevisiae, the DNA of Saccharomyces cerevisiae is readily detectable using molecular biology techniques such as PCR.

Purified Saccharomyces cerevisiae typically refers to yeast-derived products that have been purified to remove intact cells and many cellular components. Purification processes aim to reduce or eliminate detectable DNA, making it undetectable by sensitive techniques like PCR. To detect purified Saccharomyces cerevisiae, microscopic analysis is required.

Why Would Saccharomyces cerevisiae Affect Beta-Glucan Content?
Beta-glucans are naturally occurring polysaccharides, recognized for their immune-enhancing properties, found in various natural sources, including mushrooms and yeasts like Saccharomyces cerevisiae. Adding yeast extracts to mushroom powders could theoretically inflate the beta-glucan content measured in lab analyses, making the product appear more potent or beneficial than it truly is. This practice, if true, would be misleading to consumers seeking the natural benefits of mushrooms.

Our Response and the Findings
To clarify these assertions and reassure our customers, Antioxi collaborated with Helix Biological Laboratory and Alkemist Labs, independent and accredited facilities, to perform meticulous testing on our mushroom extract range. The objective was clear: determine the presence of Saccharomyces cerevisiae in our extracts.

The laboratories conducted tests on the following products:

  • Lions Mane Extract
  • Turkey Tail Extract
  • Chaga Extract
  • Cordyceps Extract
  • Maitake Extract
  • Reishi Extract
  • Agaricus Blazei Extract
  • Tremella Extract
  • Shiitake Extract

The results were conclusive across the board. Using precise DNA extraction and PCR analysis, Helix Biological Laboratory confirmed that no traces of Saccharomyces cerevisiae were detected in any of the samples tested. Each product showed a negative result for the presence of this yeast.

To further verify that Saccharomyces cerevisiae is not present in purified form, Alkemist Labs conducted microscopic analyses and also confirmed the absence of purified Saccharomyces cerevisiae in our mushroom extracts.
