Burps weird, trusted brand
I was intrigued by this complex and decided to try it out. Premier Research Labs I know to be a reliable supplement source, so I don’t worry about the product matching the description so much. It’s an interesting blend, I think the broccoli wasn’t the best choice and is what makes it burp weird, I imagine they added this for the sulforaphane benefit. I’m also a little tired of seeing turmeric in everything, makes it hard to keep your intake of turmeric to less than a teaspoon a day (the traditional max dosage). Otherwise, the other ingredients I like and it does seem to activate the reishi benefit somehow. The inulin from the artichoke and the fennel increase absorption maybe, not sure but I like it! I would like it more if they took the broccoli and turmeric out, but this product still deserves a good rating.

Plant Base Immunity Support
Premier Research Labs Reishi Immune has 815 mg of Reishi Immune Blend which has 7 different ingredients, plus 395 mg of a Reishi Pro Blend which has 2 ingredients. I am not a fan of proprietary blends, because I don’t know how much of each ingredient I am getting. This also contains organic turmeric, and Broccoli, which is an added bonus. The suggested dose is 3 capsules, and my supplement arrived fresh & safety sealed.

Top quality company and supplement
Supplements help close the gap between modern nutrition levels in our food, and the levels that were there when I was young. But, in my opinion, the supplement industry has both some of the highest integrity companies, and some of the lowest. So I try and give a detailed enough review to help get to know the company and the product better, to help you determine for yourself if you want to try this one out or not.This bottle comes a little more than half-full.If used as directed it will last one month.The “best by” date on mine is Jan 2026, so about 1.5 years from now.The capsules have a slightly herbal scent to them which is not unpleasant, and they are easy to swallow with water.I like my supplement bottles to say organic, non-GMO, GMP-certified, 3rd-party tested, and Made in USA. PRL’s bottles have more information on them than most regarding testing and quality, though it doesn’t fit exactly with the things I look for.I look into the supplement companies I use because I’ve come across so many questionable ones. Premier Research Labs is one of the supplement companies I trust above all others. From the quality of their ingredients, to not using fillers (stearates, dioxides, etc.), to their testing and beyond, it’s one of the very few companies I do not question the quality of.I seem to take longer than most to see results when starting a new supplement, but this is a great way for me to get some mushroom in me, since it’s not going to happen any other way =) And for what you are getting, in both the company and the supplement, I think it’s a good price.Thank you for reading, I hope this was helpful.

Excellent blend of ingredients and made in USA
I love the ingredients in this supplement and that Premier Research Labs is a U.S. company. I do wish that there were specific amounts listed for each ingredient, rather than just providing a total amount for a blend of ingredients. At least one ingredient (turmeric) should not be taken in large quantities so I decided to stop taking my other turmeric supplement while taking this one. I did not experience any negative effects from this supplement and it was easy to swallow. I don’t know yet whether it will have any effect on my immune system but I’m hopeful and will update my review if I notice any significant effects.

High quality, safe manufacturing!
As someone who has used, evaluated, and reviewed a significant number of supplements, I can confirm that this is one of the good ones. I cannot comment on how this supplement may affect other people since we are all a little different, but I can evaluate that product itself.Quality: The bottle arrived intact with a plastic seal on the lid and a foil seal inside. All of the capsules were also intact and none were cracked, leaking, or damaged in any way.Count: All 90 capsules were present in the bottle that I received.Manufacturing: While it is not the focus of the product page, a little research into the manufacturer (Premier Research Labs) reveals that their products are certified USDA organic and non-GMO, and their manufacturing facilities are GMP and FDA certified, and their products are manufactured in Texas, U.S.A. These are impressive certifications and they show that this is a manufacturer that can be trusted.Overall, this is a great product and I highly recommend it!

Works Great, But Is Expensive to Use Daily
The immunity support reishi mushroom supplement arrived in perfect condition. The bottle is sealed and packaged safely. There is a kind of earthy licorice smell when you first open the bottle and you can taste a little bit of the smell if you place the capsules on your tongue. I pop 1 in my mouth at a time and swallow immediately to avoid tasting anything. The capsules are small enough that they are easy to swallow, but the tradeoff is that you need to take 3 a day to meet the recommended serving size. I usually take them with my evening meal or a small snack and have not had any stomach upset.I have not noticed any side effects to taking these pills, but I do hope they are helping my immune system. They appear to be high quality. The price is a little steep for a 1-month supply. It is a great way to boost your immune system naturally, however, and may be worth investing in long term.

Seems to be a good quality product
I like this company. This product is gluten free, soy free, tested for heavy metals, and contains just the ingredients listed inside a capsule with no fillers. I really like that there are no fillers. Serving size is 3 capsules a day which means this 90-count bottle would last 30 days unless you take less like I do. The capsules are standard in size and I get no taste. They have fennel in them, which has a licorice scent to them and I do smell that herb when I open the bottle. I find it pleasant though. Mine is best buy 01/2026 so they are fresh. They also come well-sealed.
