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

Posted   by Jessica
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.
