Do the mycelium have the same compounds in them as the fruiting bodies? All the information I have seen/heard has focused on the mushrooms not roots.

Host Defense has done a massive amount of research to make these supplements as potent and effective as possible. They have found that the mycelium is the most effective at helping with the conditions addressed with each product. Some products do contain fruit body as well. Host Defense uses mycelium because the mycelium contains the higher concentration of the nutrition of the mushroom, and also produces compounds that are not found in fruiting bodies. You can read more about the Benefits of Mycelium here: https://hostdefense.com/blogs/host-defense-blog/immune-benefits-of-mushroom-mycelium-cultured-substrate-confirmed

Does it carry carry the united states pharmacopeia (usp) or nsf international (nsf) seal?

Not anywhere on the container that I can see.

How is the myecelium separated from the substrate it grows on? Or is this product mostly substrate?

no separated, probably most of it would be rice bran substrate as carbs.

Is this sold directly by host defense? i do not want to end up with a fake copy of this product -- i want the real deal.

Great stuff, 1/2 teaspoon a day noticeably improved my memory.

Great stuff, 1/2 teaspoon a day noticeably improved my memory. I eventually switched to a lower price spread, that also seems to work. It comes in a cheaper bag, less waste.

Hope it works

It does mix with hot coffee and does not change the taste.

Improved memory and clarity

My wife and I have been adding this lion’s mane powder to our morning smoothies for an over a year now, and we’ve both noticed a real difference. Our memory feels sharper, and those little moments of forgetfulness or searching for the right word seem to happen less often. It’s not some miracle cure, but there’s a clear boost in mental clarity and focus. It mixes in easily, and it’s now a regular part of our routine. We’re very happy with it.

Gold standard for best growing conditions, and mycelium based brain health

Paul Stamets is the OG.I trust his whole line. His documentary changed my worldview on fungi and the host of neurologic and physiological benefits that have gone unstudied due to the United States ban of certain chemicals in the 70s.Anyway, this is the best brand for trusting the source and he’s devoted to full circular sustainable farming.Gold standard for best growing conditions, and mycelium based brain health . So his whole line is great, but I’m just writing up Lions mane cause I was so delighted. I could get it as part of my “generic AG1” green mix I developed myself. I do a full spectrum of fruiting body and my psyllium mix and then I punctuate it with lions mane for brain health.Five star 100%

Best quality hands down

The most important thing to know about this Lions Mane is that it comes from the Host Defense Brand. I only trust Paul Stamet’s brand when it comes to any medicinal fungi products. Carefully grown in super clean environments. The Lions Mane definitely helps the quality of life in terms cognitive health and clarity.
