Mycelium – is it just a filler?

Our 100% Australian Grown Medicinal Mushrooms have gone kind of viral all over the internet. I have had a number of people ask why the mycelium/growing substrate is included.

There is a lot of debate around whether medicinal mushrooms should be 100% fruiting body or whether they should also contain the mycelium (“the roots of the mushroom”.

First off, it certainly isn’t a filler. A filler is something cheap added to a product to “bulk” it up. Adding the mycelium and growing substrate is more labour intensive and thus more expensive than just selling the fruiting body.

Secondly, the most well respected mycologist in the world believes the mycelium should be included and he helped conduct the science that seems to be in support of what he has always known.

 The peer reviewed scientific study only had 3 participants so it is in no way conclusive. It is available here:

I tend to lean on the side of including the mycelium for a number of reasons

  1. The mycelium (and even the rice substrate it is grown in) have both been demonstrated to support the body’s natural defenses.
  2. There is so much more to medicinal mushrooms than just beta-glucans. Just like any plant, the roots of the mushroom contain important benefits by only harvesting fruiting bodies you are not having a the whole food
  3. The same study also finds that the trace amounts of substrate ferment and provide their own unique benefits.

But at the end of the day the proof for me is in the “proverbial pudding”. You only need to read a few of our customer reviews to see why I’m convinced that our way of growing and producing medicinal mushrooms is the superior method.

What is it?

“Mycelium” is the root structure of the mushroom.

“Fruiting body” is the part of the mushroom that grows above the surface

“Growth substrate” is the medium used to grow the mushrooms. We use organic brown rice for this.

What about the brown rice?

Interestingly, they found the brown rice substrate was also immunologically active in a different way to the mycelium.

“In my scientific opinion, mushroom products not incorporating mycelium are at a decided disadvantage, given the results of recent research.” – Paul Stamets

My final thoughts

At the end of the day we have to listen to people we consider to be experts on specific topics.

Paul Stamets may be the most well renowned mycologist in the world. He has dedicated his whole life to mushrooms.

For me, if he says the mycelium is imperative for maximum benefit – then that is good enough for me.

      Hey Nathan, the brown rice inclusion is incidental, is there because it’s attached to the mycelium as a growing medium. In a whole bag (which would last people 1-2 months), contains only a couple of grams of rice. It has also been cooked off-reducing any arsenic. Thanks Angela

    Hi, I read your newsletter. If the brown rice growing medium is so good for you, then why try to seperate the MYCELIUM from the growing medium?
    Also, has anyone eaten raw fresh LM of yours?
    Raw is always better, so was wondering if this might be true of your LM? Thanks

      Hi Kevin, because the brown rice is incidental- the main superfood we want everyone to consume is the lions mane and the mycelium. yes we have consumed raw lions mane- they are delicious. From a medicinal viewpoint its preferable to have the lions mane cooked because it makes it more absorbable. Thanks Angela

    How is growing mycelium more labor intensive then letting the blocks go through to the fruiting stage? Aren’t you taking a step away ?

    • Justin Snyder says:

      Nope, the mushrooms still go through to the fruiting stage but trying to separate the mycelium from the growing medium is time consuming and difficult.
