Review: Fantastic product
Review: Have been using host defense lions mane powder, then brainstack and very effective. I had read that reishi can add to brain health and lower cholesterol so I tried this reishi powder. I had previously used extracts of lions mane and reishi but did not want extra alcohol. I find the reishi helps me to feel calm and has totally eliminated excessive bladder output (running to bathroom all the time). I see there is a possibility of toxicity to liver so am being careful. I give this product 150% fantastic!

## Questions & Answers

**Q: Is this product certified gluten free?**
A: From the manufacturer: Yes, our Host Defense products are gluten-free! Our MycoBotanicals® products contain an excipient called maltodextrin. Though derived from wheat, the refining process removes glutinous proteins, leaving the end product gluten-free. We adhere to all FDA "Gluten Free" labeling guidelines and standards.

**Q: is this double extracted?**
A: I’m fairly certain this product is not an extract at all. Fungi Perfecti uses mushroom mycelium grown on fermented brown rice substrates to create their Host Defense products. They don’t go into details about their process, probably a trade secret, but they imply the whole of the mycelium plus fermented substrate is processed in making the product. So you get all the nutrients. They take a very scientific approach. There is a long article on their website. Here’s a key paragraph:

“ Looking Beyond Beta-glucans
The immune system is activated multifactorially by many components in mushrooms. Beta-glucans are just one variable. There are a variety of other bioactive compounds; many of which work cooperatively to optimize multiple aspects of health and wellness. The efficacy of a multi-constituent approach has been positively confirmed in the scientific literature. Many of these active ingredients are not water soluble, meaning that they are not pulled out by hot water extraction. The inclusion of these beneficial co-ingredients increases the overall beneficial effect. These constellations of complementary constituents are the foundation of our Host Defense® mushroom mycelium-based supplement line.”

**Q: How is this Price less then on the host defense website? It’s the same weight.**
A: Well... if you look at who it is shipping from it says, The Vitamin Shoppe not Host Defense

**Q: Is this product good for meditation?**
A: I don’t think so that will help you for that ,you need to be in healthy life style first
