Dusty Yao’s years of making herbal extracts. Their shared passion for exploring the natural world, from thousands of hours of hiking through the old growth forest, and their combined ideas created the wellspring that gave birth to the Host Defense product lines that continue today.

Paul Stamets...need I say more?

Reishi mushrooms aren't very available in the produce section - capsules are easy. I would think they were reserved for ancient royals for a reason: boosting immunity, extending longevity among others. Anyone taking a blood thinner should check with doctor before using, though.

Relishi capsules

My cardiologist recommended the relishi mushrooms to me for my multiple sclerosis and also good for the heart. I was getting them from mail, this is so much more economical. I have used this brand in the past, very good.

Excellent product at an amazing price

I love the very high quality from this brand and that they are USA sourced. My husband and I both take these for general health and when tired or under stress. I am so excited to see that Thrive Market offers these at a way lower price compared to the vitamin stores I used to buy them at.

Mushroom Madness

Posted   by Nathan
I am very careful with the products I use, but when my best friend recommend I try this, I thought, why not? So I started taking this about four months ago and I can't believe i didn't do it sooner. I just went in for my yearly check up and everything was in perfect working order!

Supports Heart Health

This product is great! I started using it after having a heart attack and my doctor is impressed at how quickly I have healed and how strong my heart seems now. I credit it to this Reishi! If you want a strong heart I recommend trying this!

The Best

Posted   by Newton
I have spent a good deal of time reviewing Paul Stamets mushroom products, his lab, and clinical info on mycology for health. He is the foremost world authority on mycology and I believe his products & formulations are without exception. Reishi is one medicinal mushroom that is especially beneficial because it impacts nearly every system in the body in one way or another. I am delighted to see these products being carried here -- at a GREAT price as well -- and hope you will expand your offerings to include his other formula & individual mushrooms.
