Higher Quality Standards Through Testing

Mushroom supplements are largely unregulated and most industry-standard testing practices don’t show the complete picture.

WholeSun Wellness goes above and beyond with new testing methods that offer a more complete approach to mushroom quality and potency.

Industry-Standard Testing Methods

With little official regulation, third-party agencies and governing bodies like the USDA are primarily responsible for overseeing mushroom farming and processing practices. But these agencies are not involved in determining what makes a high-quality supplement.

Manufacturers are responsible for setting their own standards and figuring out how to meet them.

There are several industry-standard testing methods that reveal microbial levels, heavy metal levels, and pesticides. The material may also go through additional testing to determine polysaccharide levels.

Our New Approach to Testing

The standard testing methods in our industry have severe limitations and cannot accurately validate the level of quality we demand. So, WholeSun Wellness adopted new testing methods that reveal more than the standard testing protocols.

A Match made in Mushrooms

We work with multiple accredited third-party laboratories that perform a wide range of testing protocols to verify identity, purity, potency, and quality. Depending on the ingredient and application, testing may include species identification, beta-glucan analysis, microbial screening, heavy metals, pesticides, active compound testing, and other relevant quality assurance measures. We believe no single test tells the entire story, which is why we utilize multiple analytical methods and independent laboratories to ensure product integrity and consistency across our supply chain.

Testing Protocol

WholeSun Wellness mushrooms are tested four times before hitting the shelves. Our growers and manufacturers test after harvesting the mushrooms and after the extraction process. Then, the material is tested by a third-party lab

Each batch of our mushrooms undergoes a rigorous protocol to guarantee quality and purity

Testing for beta-glucans

Beta-glucans make up to 50% of the mushroom cell wall and are heavily studied for their effects on the body. It makes sense that beta-glucans are a huge selling point for any mushroom supplement.

High beta-glucan levels do not necessarily mean a high-quality product. Standard testing confuses beta-glucans and alpha-glucans.

  • Beta-glucans are often detected through a basic polysaccharide test that measures the presence of complex sugars. The standard test detected beta-glucans and alpha-glucans.

  • Alpha-glucans are pure starch. They do not have therapeutic benefits. It is like eating rice, and who wants rice in a mushroom supplement?

  • Artificial beta-glucans are required – Companies that rely on a standard polysaccharide test will add artificial beta-glucans to meet whatever is promised on the label (for example, 10% or 50 mg).


Mushrooms are much more than beta-glucans. We are determined to continue developing more accurate and rigorous testing for all the components in mushrooms.

Nutritional Profile

Mushrooms are food. They have a complex blend of nutrients and minerals, just like any whole food product.

WholeSun Wellness is the first in the industry to test and publish the nutritional profiles of every product and to showcase them on our packaging.
