Mushroom Mycelium Benefits: What is It and How Can We Use It to Our Advantage?

Mushrooms have long been valued for their various health benefits, but the hidden powerhouse beneath them is the mycelium. In this article, we'll explore mushroom mycelium benefits —from immune support to enhancing nutrient absorption. Mycelium health benefits extend beyond the mushroom itself, offering potential advantages when consumed in the form of mycelium powder or supplements.

Curious to know how eating mycelium can improve your wellness? Let's dive into the benefits of mycelium and how you can incorporate it into your routine.

Mushroom mycelium is a vital part of the mushroom growth cycle, growing beneath the surface in a network of filaments called hyphae. While often compared to plant roots, mycelium is much more complex. It anchors the mushroom and supplies it with nutrients, but it also releases enzymes that break down organic matter, providing nutrients the mushroom can absorb.

When it comes to mycelium mushroom benefits , it's important to note that some mycelium powder supplements may not contain actual mushrooms and can offer fewer benefits compared to fruiting body supplements, fueling the "mycelium vs fruiting body" debate.

However, mycelium has potential in other applications, which we’ll explore below, starting with how it supports fungus life.

Mycelium mushroom benefits are vast, playing a crucial role in ecosystems by recycling nutrients through organic matter decomposition. This process not only feeds the soil and surrounding plants but also sustains the mushroom's life.

Mycelium forms a dense web beneath the ground, intertwining with plant and tree roots to create a "symbiotic ecosystem." Acting as a cell-signaling network, mushroom mycelium helps plants communicate and share nutrients, particularly those less accessible at the soil’s surface. In return, mycelium receives carbohydrates to support its growth.

The mycelium network can grow to immense sizes, connecting entire ecosystems. The largest known organism on Earth is a honey mushroom mycelium spanning 2.5 square miles. These mycelium health benefits extend far beyond mushrooms, influencing ecosystems and offering practical uses for society.

Before we dig into all the ways that the mushroom mycelium can be used, we want to touch on one way that it is most commonly used that isn’t so useful. We mentioned that mushroom mycelium is often used in mushroom supplements, which are typically sold as wellness supplements designed to reap the many benefits associated with functional mushrooms. 

However, mycelium supplements are a sort of cop-out for manufacturers, although they will often frame it as though mycelium supplements are superior. Here’s why they aren’t:

When commercially farmed mushroom mycelium is grown, it's grown on blocks of substrate, usually a grain like oats or rice. We mentioned earlier that mycelium is impossible to separate from the growing medium. So, at harvest, the entire block of grain is thrown into the blender alongside the mycelium mass. The material is ground up together and used as the “mycelial supplement.” That means that the end material contains a lot of starch filler.

Even without the starch, mycelium supplements aren’t so stellar to begin with. In fact, the mycelium of the mushroom is thought to contain a beta-glucan content of around 5%, while the mushroom body (the stem and cap portion) can contain a beta-glucan content of 30% or more. Beta glucans are the bioactive compounds thought to give mushrooms their health benefits.

So, in the end, mycelial supplements are just an easy, cheaper way for manufacturers to legally market a product as a mushroom supplement, even though they contain none of the mushroom benefits. 

Many brands producing mycelium products make exaggerated claims about their superiority. While functional mushrooms rely on mycelium in nature, this does not imply that mycelium is essential in supplements. Once mushrooms are fully formed, their health benefits become independent of mycelium.

There’s no evidence that consuming mycelium enhances the absorption of nutrients and beta-glucans found in whole mushrooms. Some brands claim their substrate is immunologically active due to fermented grains, which may be true, but this doesn’t mean it has higher beta-glucan content. In fact, adding grain and mycelium often dilutes overall beta-glucan concentration.

Although these brands reference independent research, they rarely provide studies comparing mycelium supplements to whole mushroom supplements. Ultimately, this is more marketing than science. 

For the best mycelium health benefits, choose fruiting body mushroom supplements to ensure you receive the full range of biologically active beta-glucans and wellness benefits.

Although mycelium isn’t that great for supplements, it is incredibly useful both for the mushroom and as a consumable product. In fact, mycelial products are making their way into a new wave of eco-friendly foods and textiles. Some way that mycelium may be used includes:

Some fungus will break down bacteria, plastics, and other waste materials to help remove it from the environment. The act of adding this fungus to an area to help clean the environment is called "mycoremediation."

Roll back to when we talked about mycelial functions. Mycelium releases enzymes that break down "food" into nutrients. Those nutrients can be consumed by the fungus, but are also consumed by the surrounding plants and used to enrich the soil. Through this enzyme process, some fungi can eliminate non biodegradable waste like plastics or hydrocarbons. 

Some mycelium can even help to convert petroleum, heavy metals, and even nuclear waste into useful nutrients for the environment. This is great for assisting in reforestation or cleaning up after oil spills. In general, the presence of fungus will result in a cleaner environment. 

Although the mycelium isn't great for supplements, it can be a useful food source. Mainly, it is used to make plant-based meat. The entire mycelium is ground up with the remaining grain and seasoned to create a product that looks and feels similar to meat products. 

This is a major benefit to plant-based diets because fungus includes whole amino acids like meat-based proteins and is therefore a healthy source of protein for vegans, vegetarians, or anyone with an adventurous palate. 

What's best is that some sources suggest that mycelial based "meat" products require over 90% less land and energy than is required to raise cattle. 

Mycelium is dense and made of chitin, the polymer that makes up an insect's exoskeleton. For this reason, researchers have been digging into the ways that mycelial material can be used to create durable, biodegradable versions of many materials we use today, like:

• Packaging: Mycelium can be used to create an inexpensive packing foam that’s far more biodegradable than what we have today. Plus, it’s relatively inexpensive and flame resistant, so it could eventually be useful for commercial and personal shipping purposes. 
• Leather and textiles: Mycelium can be used to make a vegan leather alternative that can be tanned and dyed to create a material that looks and feels like leather. In fact, Adidas has already released a concept Mylo leather shoe, the Stan Smith Mylo, and will likely be furthering this innovation. 
• Building materials: Mycelium may help lighten the strain on our tree supply when it comes to building materials. Mycelium can be used to create lightweight, durable building blocks, tiles, particle boards, and more. It’s also currently being used to create fire-resistant insulation and adhesive that can be used in construction. These materials are not commonly available yet, but will certainly be part of a new wave of construction materials that’s more environmentally focused.

It may seem obvious, but the main push behind using mycelium to create these innovative food and textile products is to help reduce the carbon footprint behind these industries. Using mycelium is a great alternative where its applicable because:

• It consumes less energy while growing. 
• It grows faster than trees. 
• It produces fewer emissions during farming and manufacturing. 
• It does not require as many chemicals as petroleum/plastic based products. 
• It’s durable enough for the life of the product but is still biodegradable. 
• It’s sustainable. 

Many people will sum up the mycelium as “part of the mushroom” like a root is part of a plant. But it’s important to clarify that that’s not the case. The mushroom refers specifically to the cap, stem, and gills, which is also referred to as a fungus’ “fruiting body.” 

Instead, think of it this way–both the mushroom and the mycelium are parts of the fungus. Both parts are integral and necessary, though they have very different compositions and uses. 

The fruiting body contains the mushroom’s spores. When released, they travel through the air or water until they reach a suitable substrate, where they grow into hyphae and eventually into mycelium. 

The fruiting body is the part of the fungus that contains the beta-glucans responsible for the wellness benefits associated with mushrooms. It's also the part most commonly used as food, hence it's the part that is most commonly grown and foraged. It’s separate from the mycelium, but integral to the growth of new mycelial masses, and the mycelium is integral to the growth of the mushroom. 

Now to the most important question for most mushroom supplement consumers:

If you came here to learn what the mycelium is and how it functions, you’re all set. But if you are like many mushroom consumers, you want to know more–are mycelium supplements or fruiting body supplements better? 

The answer is clear–supplements made from the fruiting body are cleaner, more pure, and contain a higher concentration of the therapeutic compounds that mushrooms are known for. 

Sure, mycelium is a crucial part of the process used to grow and create mushroom supplements, but it doesn’t contain most of the mushroom’s beta-glucans. Using mycelium in mushroom supplement is like putting the dirt, root, and tree bark from an apple tree into the applesauce. 

Of course, the mycelium vs fruiting body content doesn’t tell you everything you need to know about the supplement quality. Choosing a high-quality mushroom supplement is the most important factor in whether you will experience true benefits–and not all mushroom supplements are safely and responsibly made, regardless of which part of the mushroom they contain.  

Here are some other things to consider:

• Whole mushroom or mushroom extract? Is the supplement made from whole, dried mushrooms that are ground into a powder, or is it a mushroom extract? Whole mushroom powder will contain all of the nutrients and fiber and bioactive compounds. An extract, however, will contain a concentrated version of the mushroom's bioactive beta-glucans, and is often the kind of formula chosen for medicinal use. 
• How is it made? Take a look at the entire manufacturing process. High-quality supplements should be made in a cGMP-compliant facility using FDA-approved ingredients. A great product will be made using organic and responsibly sourced ingredients.
• Is it lab tested? Like all supplements in the U.S., regulations are lower than what’s required for pharmaceuticals. So, it's up to you to check and make sure that products contain what they say they contain. For mushroom supplements, that means third-party lab tests that prove potency and purity.
