Real Mushrooms vs Host Defense: Ingredients, Price and Refunds

Real Mushrooms and Host Defense both sell mushroom capsules marketed for immune and brain support, but they start from different raw material. Real Mushrooms says its capsules are made from fruiting bodies, not mycelium grown on grain. Host Defense says its capsules use mycelium grown on organic brown rice. Below you will find the prices, labels, guarantees, shipping and reviews side by side, so you can pick the one that fits your routine.

Real Mushrooms vs Host Defense at a glance

Figures below are as shown on the brand websites on October 6, 2026 and on Amazon on October 12, 2026. Ratings and sales estimates are the listings’ own numbers, not a verdict on quality.

What each brand sells

Real Mushrooms sells its mushrooms as capsules and powders. Its Lion’s Mane, Turkey Tail and 5 Defenders capsules come in 90, 120, 200 or 300 counts depending on the product. Its 5 Defenders blend is a mix of five extract powders: Reishi, Shiitake, Maitake, Turkey Tail and Chaga. Its top-selling capsules also include Cordyceps, Reishi, Tremella and Chaga.

Host Defense sells capsules, powders and liquid extracts. Its capsules include single species such as Turkey Tail and Reishi, plus blends: Stamets 7, a seven-mushroom blend, and MyCommunity, a 17-species blend. Its MycoShield is a liquid spray of five mushroom mycelium extracts. Its packaging images call it the “#1 bestselling mushroom brand in the U.S.”

What these mushrooms are

Host Defense’s labels give the Latin names: Hericium erinaceus for Lion’s Mane, Trametes versicolor for Turkey Tail, Ganoderma lucidum for Reishi and Inonotus obliquus for Chaga. Real Mushrooms says Lion’s Mane “is used in Traditional Chinese medicine for both brain and digestive support,” and describes Turkey Tail as backed by decades of research and traditional use. Those are the brands’ own descriptions. Reishi appears in both lineups, and for background on it see our reishi mushroom guide.

Raw material and potency claims

This is the biggest difference between the two. Real Mushrooms says its products are made from “real mushrooms (fruiting body), not mycelium fermented grain,” and that its extracts are hot-water extracted. Its comparison table sets its products against “other brands” that use mycelium fermented grain.

Host Defense takes a different view. Its FAQ calls mycelium “an excellent ingredient for supporting health,” and says its capsules are made with heat-treated, custom-dried mushroom mycelium powder grown on organic brown rice, with the cultured rice kept in the product. Its Maitake and MyCommunity capsules also include mature fruiting bodies, according to the FAQ. Its liquid extracts are formed from mycelium and fruiting bodies and contain 30 to 40% alcohol, per the same page.

On potency, Real Mushrooms says its Lion’s Mane and Turkey Tail extracts are guaranteed to contain more than 30% beta-glucans, and that its 5 Defenders extract is optimized to contain more than 20%. Its Turkey Tail page describes beta-glucans as polysaccharides. Host Defense answers beta-glucan questions with polysaccharides instead. Both numbers are each brand’s own measure, so read them as that brand’s standard rather than a common yardstick.

Label amounts per serving

Host Defense’s Turkey Tail label lists a serving of 2 capsules and 30 servings per container, with 1 g of Turkey Tails (Trametes versicolor) per serving. Pullulan is its only other ingredient, and the panel lists 5 calories and under 1 g of carbohydrate. Its Reishi label lists 1 g of Reishi per 2-capsule serving. Its MyCommunity label lists all 17 species, each in milligrams per 2-capsule serving, from 12 mg to 148 mg.

Real Mushrooms’ product pages have a View Supplement Facts panel. Open it on the exact product you plan to buy for its per-serving amounts and other ingredients.

What the research says about immune support

Real Mushrooms says its products “support healthy immune system function,” and Host Defense’s Turkey Tail page says it “supports an engaged and balanced immune response.” The research is more cautious than those labels. Harvard Health’s guide on how to boost your immune system says some preparations “have been found to alter some components of immune function,” but that “thus far there is no evidence that they actually bolster immunity to the point where you are better protected against infection and disease.” The NIH Office of Dietary Supplements, in its fact sheet on dietary supplements for immune function, says botanicals and probiotics “are not essential in the body but might affect immune function.”

A 2023 review of immune-supporting foods covers mushrooms in general, not these capsules. It reports that beta-glucan from mushrooms “has been shown to stimulate the immune response of NK cells, B cells, T cells, and macrophages.”

If you are asking how to boost your immunity fast, the research points to steady habits rather than a quick fix. Stony Brook Medicine’s dietitians say no food or pill is guaranteed to boost your immune system. The CDC’s Healthy Habits: Enhancing Immunity page lists the routine that matters: eat well, be physically active, keep a healthy weight, get enough sleep, don’t smoke and avoid excessive alcohol.

Side effects, interactions and who should ask a clinician first

Host Defense’s FAQ is the more specific of the two. It says that if you are having surgery, have a medical condition, or take prescription drugs, including blood thinners or insulin, you should consult your health practitioner before taking its products. It also says there is not enough research to safely conclude that mushroom supplements are safe during pregnancy or for children, so it does not suggest its supplements for those groups.

Real Mushrooms’ pages say its statements have not been evaluated by the Food and Drug Administration, and that its products are not intended to diagnose or treat any disease. For questions about your own medicines, call its customer line at 1-800-263-4387, which its footer lists, before you start.

Price per bottle and per day

Real Mushrooms’ 120-capsule Lion’s Mane costs $34.95, about $0.29 a capsule, and its 300-capsule Amazon listing costs $69.95, about $0.23 a capsule. Its site lists the 300 size as a 25% bonus. Host Defense’s 120-capsule Lion’s Mane is $47.21 on Amazon, about $0.39 a capsule, and its 60-capsule is $23.74, about $0.40 a capsule.

For Turkey Tail, the label gives Host Defense’s serving directly. Its 30-capsule bottle is $20.95 on its site, about $0.70 a capsule, which is about $1.40 a day at the 2-capsule daily serving its FAQ suggests. Its 60-capsule Turkey Tail on Amazon is $25.46, about $0.85 a day, and its 120-capsule at $47.21 is about $0.79 a day, at the same serving. Real Mushrooms’ 90-capsule Turkey Tail is $39.95 on its site, about $0.44 a capsule, and its 200-capsule size is listed with a 10% bonus. For its daily amount, use the suggested use on each product page and multiply it by the per-capsule price.

Real Mushrooms’ site also advertises bundles that save up to 30% and 20% off a first order through its email sign-up. Host Defense’s larger sizes carry Subscribe and Save 20%. Check today’s price at checkout, because prices and bundles change.

Refunds, guarantees and shipping

Real Mushrooms’ product pages show a 100-Day Satisfaction Guarantee and a 100 Days Money-Back Guarantee, with free shipping on orders of $75 or more. Its footer has a Returns link, and it is worth reading for the conditions before you buy.

Host Defense’s product pages say shipping is calculated at checkout. Its shipping policy says it ships by USPS and UPS, that turnaround averages three business days or less, and that only UPS Next Day has a guaranteed transit time. USPS Priority and First Class transit times are not guaranteed. UPS orders need a physical address, not a PO box. Its refund terms sit on the Refund Policy page in its footer, which is the page to read before you order.

What buyers say in reviews

Real Mushrooms’ own pages show 4.83 out of 5 from 986 reviews for 5 Defenders, 4.77 from 1,162 for Lion’s Mane and 4.82 from 465 for Turkey Tail. Its Lion’s Mane page says those averages combine its Shopify store and Amazon reviews. Several reviews on its pages praise its customer service and its subscription. Its badges also claim 94,000+ 5 star reviews.

Host Defense’s own pages show smaller counts: 5 stars from 9 reviews for MyCommunity, 5 from 12 for Reishi and 5 from 17 for Turkey Tail. Its review section says the reviews reflect the contributors’ views and that it has not verified their accuracy. Reviewers on those pages mention capsules that are easy to swallow and subscriptions.

On Amazon, the Lion’s Mane listings show 4.5 from 23,788 reviews for Real Mushrooms and 4.6 from 15,106 reviews for Host Defense. Monthly sales estimates for the 120-count bottles are about 10,000 and about 5,000. Those are the listings’ own figures, not a quality ranking.

Are these companies legit, reputable and Canadian?

Real Mushrooms has live product pages and Amazon listings with more than 23,000 reviews, and its pages state a 100-day guarantee. Its footer lists a mailing address in Calgary, Alberta, Canada, so it presents itself as a Canadian company. Real Mushrooms says it has 50+ years of mushroom growing experience, and that consumers in the ConsumerLab.com Annual Supplement Survey rated it Best Mushroom Supplement Products five years in a row. These are the company’s own statements and the Amazon listing figures. Whether it is a good company for you comes down to the guarantee, the testing claims and the label.

Host Defense is also a sold product, with its own site, product pages and Amazon listings. Its contact page lists a phone number and email for direct customers, and weekday hours in Pacific Time. Judge it on the same points: the guarantee, the testing claims and the label.

Third-party testing

Real Mushrooms says its products are 3rd party tested. Its comparison graphic lists “Guaranteed beta-glucans & 3rd party tested,” and its pages say each batch is lab-verified for beta-glucan content. Host Defense’s FAQ says its supplement testing focuses on identity, composition, purity and strength rather than nutritional, mineral or other analyses. Both of these are the brands’ own statements. To see what a specific bottle was tested for, ask each company for the test results for that lot before you buy.

Who each one suits

Real Mushrooms suits you if you want a fruiting-body product, a five-mushroom blend in 5 Defenders, or larger Lion’s Mane bottles at a lower price per capsule, and if a 100-day guarantee and free shipping on orders of $75 or more matter to you. Host Defense suits you if mycelium grown on organic brown rice is the form you want, if you want the 17-species MyCommunity blend, a single species in a 30-capsule bottle, or powders and liquid extracts. If you are pregnant, nursing or buying for a child, Host Defense’s FAQ does not suggest its supplements for those groups, so ask a clinician before choosing either.

Questions that decide it for you

Neither brand’s claims can be ranked by effectiveness on this page, so the choice rests on these questions:

• Do you want fruiting bodies, or mycelium grown on organic brown rice? Each brand says its own form is the right one.
• Which species do you want: Lion’s Mane, Turkey Tail, Reishi, or a blend?
• What will it cost per day at the serving the label or the suggested use gives? Divide the bottle price by the days it lasts.
• Which refund terms do you accept? Compare Real Mushrooms’ 100-day guarantee with Host Defense’s Refund Policy.
• Do you take blood thinners, insulin or any prescription medicine? Ask your clinician before you start either product.

Checklist before you order

• Open the Supplement Facts on the exact bottle size you plan to buy.
• Ask the brand for the third-party or lot test results for that bottle.
• Read the Returns page (Real Mushrooms) or the Refund Policy (Host Defense) before you check out.
• Check today’s price at checkout, because prices and bundles change.
• Ask a clinician first if you take blood thinners, insulin or prescription medicine, or if you are pregnant, nursing or buying for a child.
