The danger of non-organic, untested mushrooms

You don’t need to shell out the top price for pure, organic functional mushrooms. But you do need to know how to recognise the best quality. If you have poor-quality mushrooms that are not organic, haven’t been tested, and most likely contain substances you don’t want in your body, there are risks attached:

  • Contaminants. Mushrooms can absorb toxins from the environment, such as heavy metals and pesticides. Non-organically grown mushrooms have a higher risk of contaminants because they are exposed to artificial chemicals and pesticides during cultivation.
  • Fungi and bacteria. Untested mushrooms may contain fungi and bacteria that can be harmful. This may be because they have been grown or processed in unhygienic conditions.
  • Unpredictable effectiveness. If mushroom supplements aren’t extensively tested by third-party external laboratories, you can’t be sure what the concentrations of active ingredients are, such as polysaccharides and beta-glucans.
  • Allergens. With insufficient testing for potentially allergenic substances, you don’t know whether the supplement is safe for people with allergies, such as a sensitivity to gluten or certain moulds.
  • Unreliable information on the label. If the mushrooms are not tested or certified, the manufacturers can put anything on the label. They may state the composition of the ingredients differently, which can lead to dosage errors. This may even compromise the safety of the supplement.

It’s clear that you should only choose organic and tested mushrooms when buying mushroom supplements. That’s why we (as the only mushroom shop in Europe) have our mushrooms extensively tested by third-party laboratories. The lab results can be found on the product pages of our products.

5 Tips for buying the best mushroom supplements

Do you know which medicinal mushrooms you want? Then it’s time to figure out how to buy the best quality. Ask yourself these questions:

1. Are the mushrooms organic?

Organic mushrooms, such as MushPeak’s medicinal mushrooms, are produced without the use of synthetic pesticides and herbicides. By choosing organic mushrooms, you know you’re not putting those substances into your body.

In addition, some studies suggest that organic food contains more nutrients than food that is not organic (1). Organic mushroom supplements do contain fewer artificial additives, preservatives, and fillers. If you want a more natural and pure supplement, it makes sense to choose organic supplements.

2. What’s on the ingredient list?

Some mushroom supplements contain additives, such as cocoa or maca. This does not enhance the effectiveness of the mushrooms, but you pay more for those extra ingredients. If you don’t want that, check the ingredients list to make sure your product is based solely on the mushroom in question.

You can also look at the concentration of active ingredients, such as beta-glucans and polysaccharides. Beta-glucans fall under polysaccharides, but some manufacturers test or list only the polysaccharides. In those cases, the percentage of beta-glucans may actually be lower than, say, alpha-glucans, which are also considered polysaccharides.

It isn’t clear yet to what extent alpha-glucans contribute to the health benefits of functional mushrooms. However, it is clear that beta-glucans play a major role.

3. What purification and extraction methods have been used?

The purification and extraction methods determine how effective the mushroom supplements are. How are the mushrooms treated to extract the active substances? This is important because not every method is the same.

There are a number of steps in extracting the active substances, which include applying hot water or steam, and applying ethanol AND water. The latter creates the Dual Extracts, which contain both water-soluble and fat-soluble compounds. This is not necessarily better than the first step.

What is important is that the right temperature is used. Some bioactive compounds in mushrooms are sensitive to heat and lose their efficacy when using water or steam that’s too hot. This is why a special “grinding” method is used for MushPeak’s mushroom supplements, so that all nutrients remain intact.

4. Are the mushroom supplements tested by external laboratories?

To check the quality and purity of mushroom supplements, they have to be tested by external laboratories. There, they verify that the products are free of contaminants, such as heavy metals, pesticides, and microbial contamination.

Third-party external laboratories operate independently, meaning their test results are not influenced by commercial interests. This is important; it increases the objectivity and reliability of the tests. You should also be able to see the results of the tests (as with our products), otherwise you still don’t know anything.

5. What do customers say about quality and service?

Customer reviews generally say a lot about the quality of the products and the company’s service. The latter is also important; consumers should be treated and advised well, otherwise you will be doing business with a company that doesn’t have the right priorities.

In customer reviews, you can read what people think about the effectiveness of the mushroom supplements and whether they experienced any side effects. You can also see which mushrooms helped them to resolve any health issues. This will help you better understand whether the product meets your needs and expectations.
