Clearing the Air: Mushrooms, Mycelium, Starches, and Gluten – What You Need to Know

Clearing the Air: Mushrooms, Mycelium, Starches, and Gluten – What You Need to Know

There’s a lot of confusion around mushrooms, especially when it comes to how they’re grown, processed, and labeled. One of the most common misunderstandings involves mushrooms grown on grain substrates and whether they contain gluten or starches. For people with gluten sensitivities or celiac disease, these questions are important. To make matters more complex, some mushroom products contain mycelium instead of the mushroom fruiting body, leading to even more uncertainty. Let’s dive deep into the science behind mushroom cultivation, the role of mycelium, and how to choose the right product for your needs.

Do Mushrooms Contain Gluten or Starches?

Mushrooms themselves are naturally gluten-free. As fungi, they are neither plants nor grains and do not contain gluten or starches. However, the way mushrooms are grown and processed can introduce these compounds into the final product. This typically happens when mycelium—the root-like structure of fungi—is grown on a grain substrate.

Grain substrates are commonly used in mushroom farming because they provide an excellent food source for the growing fungi. In mycelium-based products, remnants of this grain can remain, potentially introducing starches and even trace amounts of gluten into the product. While these levels may be negligible for most people, they can pose a concern for those with severe gluten sensitivities or celiac disease.

Mushrooms Grown on Grain: What’s the Big Deal?

When people hear that mushrooms are “grown on grain,” they often assume that the mushrooms themselves contain gluten or starches. It’s important to clarify what this means. Growing on grain refers to the process of using grains like oats, rice, or wheat as a substrate for mycelium growth. This substrate acts as a nutrient-rich bed, allowing the mycelium to develop and eventually produce fruiting bodies—the mushrooms we recognize.

In products made from the fruiting body alone, there is no grain left in the final extract, ensuring the product is free of gluten and starches. However, in products made from mycelium, the grain substrate often remains embedded in the mycelium. When this happens, the final product may contain starches or gluten depending on the type of grain used and how it is processed.

Fruiting Body vs. Mycelium: What’s the Difference?

Understanding the difference between the fruiting body and the mycelium is key to navigating mushroom products. The fruiting body is the reproductive structure of the fungus, commonly recognized as the mushroom. This part is typically packed with beneficial compounds, such as beta-glucans, which support immune health, and triterpenes, which are known for their anti-inflammatory properties.

Mycelium, on the other hand, is the vegetative part of the fungus. It acts as a nutrient-absorbing network, similar to the roots of a plant. Mycelium also contains bioactive compounds, but these can differ from those found in the fruiting body. For example, mycelium is rich in specific polysaccharides and enzymes that may complement the health benefits of fruiting bodies.

Why Is Mycelium Used in Some Products?

You might wonder why some manufacturers use mycelium in their mushroom products. The answer lies in the unique compounds that mycelium can provide. Certain polysaccharides and enzymes found in mycelium are not present in the fruiting body, making it a valuable source of additional health benefits.

However, there’s a trade-off. Mycelium grown on grain often retains a portion of the substrate in the final product, which dilutes the concentration of active compounds like beta-glucans. In some cases, the grain-based starches can make up a significant portion of the product. While mycelium-based products can still offer health benefits, it’s essential to choose high-quality options that clearly label their contents.


Starches in Mushroom Products

Starches, like gluten, are another area of concern for consumers seeking pure mushroom products. Starches come from the grain substrate used during the cultivation process. When mycelium is harvested along with the grain it was grown on, these starches can remain in the final product. While starches aren’t inherently harmful, they can dilute the potency of the mushroom compounds and reduce the overall effectiveness of the product.

For those with specific dietary needs, such as managing blood sugar levels or avoiding grains altogether, understanding the starch content of a mushroom product is crucial. Look for products made from the fruiting body alone, as these are less likely to contain residual starches from grain substrates.

Choosing the Right Mushroom Product for You

When it comes to choosing a mushroom product, it’s all about understanding your needs and preferences. Here are a few tips to help you make an informed choice:

  1. Check the Label: Look for terms like “fruiting body” or “mycelium” to know what part of the mushroom is used. If the product lists “mycelium on grain,” it may contain residual starches or gluten.
  2. Know Your Goals: If you’re seeking high concentrations of beta-glucans or triterpenes, fruiting body extracts are often a better choice. If you’re interested in the unique compounds found in mycelium, ensure the product is well-sourced and transparent about its ingredients.
  3. Ask Questions: Don’t hesitate to contact manufacturers for clarification about grain substrates, gluten, or starch content.

All Ecogenya and Fantastic Fungi mushroom extracts are made exclusively from the fruiting bodies of mushrooms, ensuring no residual grain, gluten, or starches in the final product. This makes them an excellent choice for those with gluten sensitivities or anyone seeking a pure, potent mushroom supplement.
We do offer some specialty extracts made from mycelium, but they are by special order only.

The Gluten-Free and Starch-Free Advantage of Fruiting Body Extracts

One of the key advantages of using fruiting body extracts is their purity. Since these products are made from the mushroom itself, with no grain substrate included, they are inherently free of gluten and starches. This not only makes them safer for people with dietary restrictions but also ensures that the product delivers a higher concentration of active compounds.

Bridging the Gap: Mycelium and Fruiting Body Together

While fruiting bodies are often preferred for their potency and purity, it’s worth noting that mycelium has its place in mushroom supplementation. The unique compounds in mycelium can complement the benefits of fruiting bodies, offering a well-rounded approach to health. Some high-quality products combine both mycelium and fruiting bodies, ensuring the best of both worlds.

Conclusion

Mushroom products can be a fantastic addition to a healthy lifestyle, but understanding their cultivation and processing is key to choosing the right one. Whether you’re avoiding gluten, managing starch intake, or simply seeking the most potent extract, knowing the difference between fruiting body and mycelium is crucial. By prioritizing transparency and quality, you can enjoy the incredible benefits mushrooms have to offer—without any unwanted surprises.
