Host Defense vs Om Mushrooms: Price, Side Effects and Refunds

The short answer: Host Defense is the simpler pick if you want single-mushroom capsules made from mycelium, and Om suits you better if you want one blended powder with ashwagandha or a mushroom coffee with caffeine. Neither brand has been shown to boost immunity, so choose by format, price per serving and refund terms, and read each bottle’s Supplement Facts panel before you buy.

Host Defense vs Om Mushrooms at a glance

Do mushroom supplements actually work?

Both brands lead with immune language. Host Defense’s MyCommunity page promises “comprehensive immune support” and says it “promotes the immune system’s natural ability to communicate and react.” Om’s Master Blend label says it helps support immune health, vitality and stress relief. Those are the brands’ own words, and they are the claims to weigh against the research.

The research is more modest than either label. A review of immune-supporting foods in PubMed Central says beta-glucan extracted from mushrooms “has been shown to stimulate the immune response of NK cells, B cells, T cells, and macrophages,” citing earlier studies. That is a summary of studies on the compound in general. It is not a test of either brand’s product or dose.

Harvard Health is more skeptical of the idea of boosting immunity at all. Its Harvard Health guide to boosting your immune system says “the concept of boosting immunity actually makes little sense scientifically.” It puts the emphasis on habits such as not smoking, exercising regularly and getting adequate sleep. Read the immune claims on both product pages with that in mind.

What does Host Defense say about its products?

Host Defense’s site footer names Paul E. Stamets and Fungi Perfecti, LLC. Its FAQ says its formulation team includes “the one and only Paul Stamets.” Its capsules are made from heat-treated, custom-dried mushroom mycelium powder, harvested at peak growth and sealed in plant-based pullulan capsules. Its powders use the same material, and the company says it does not isolate or concentrate particular compounds in them. Its bottle art, captured October 6, 2026, says “#1 bestselling mushroom brand in the U.S.”

The product pages describe MyCommunity as “comprehensive immune support,” Reishi as “longevity support” that says it “supports energy and stamina,” and Turkey Tail as “microbiome & immune support.” Each page says its statements “have not been evaluated by the Food and Drug Administration.” Host Defense also says its review section reflects contributors’ views, and that it “has not verified the accuracy of these statements.”

The product range is split by design. Turkey Tail, Reishi and Lion’s Mane are single-species capsules. MyCommunity is a 17-species blend, and Stamets 7 is a seven-mushroom blend, according to its FAQ. Its contact page lists 1-877-504-6926 and info@fungi.com, open Monday to Friday, 8:30am to 4:30pm Pacific.

What does Om Mushroom Superfood say about its products?

The Master Blend label says it “packs 10 powerful mushrooms plus KSM-66® Ashwagandha root extract into one comprehensive formula,” and calls it “your daily multi, but make it mushrooms.” The ten mushrooms are lion’s mane, king trumpet, chaga, turkey tail, cordyceps, Antrodia camphorata, maitake, sun mushroom, reishi and shiitake.

Om uses “Full Spectrum” to mean both parts of the fungus. Its own explanation is that “mushrooms tell two stories: the fruiting body above and the mycelium below.” Put simply, the fruiting body is the part you see, and the mycelium is the growth underneath it. Om says the two have different bioactives, so it uses both.

The Mushroom Coffee Blend is real Arabica coffee with lion’s mane and cordyceps in it. Its coffee page says the mushrooms are “whole mushroom powder, dried and milled, never extracted.” Om describes it as a morning coffee, “not a sleep or stress product,” and says most people notice benefits in weeks two to four. Om’s about page says every batch is tested in its own laboratory and again by a third-party lab for heavy metals and other contaminants.

Is ashwagandha the same as lion’s mane?

No. Om’s Master Blend label lists ashwagandha root extract separately from its ten mushrooms, and lion’s mane is one of those mushrooms. The Mushroom Coffee Blend has lion’s mane and cordyceps, with no ashwagandha on its label. If you want to know what studies say about ashwagandha itself, our ashwagandha benefits research page covers it.

What does each label list per serving?

Host Defense’s Reishi label lists reishi (Ganoderma lucidum s.l.) at 1 g per 2-capsule serving. The same line names mycelium and fermented brown rice biomass as its source. The MyCommunity label names pullulan as its capsule, and its bottle art lists the 17 species. For the amount of each species in MyCommunity, read the Supplement Facts panel on the bottle you buy.

Om’s Master Blend label lists 250 mg of ashwagandha root extract per serving. A serving is 2.25 g, or one level teaspoon, and the container holds 28 servings. Check the panel for the amount of each mushroom. The coffee label lists 110 mg of caffeine per serving, from Arabica coffee and CoffeeBerry whole coffee fruit extract. One packet, or about a tablespoon from the canister, makes one serving.

What does each one cost?

On Amazon, as of November 2, 2026, Host Defense’s Turkey Tail 60-capsule bottle is listed at $25.46, and so is its Lion’s Mane 60-capsule bottle. Its 120-capsule Lion’s Mane bottle is listed at $47.21. The Turkey Tail label lists 2 capsules per serving and 30 servings per container, so that bottle works out to about $0.85 per serving.

On Host Defense’s own capsule product pages, as of October 6, 2026, the price shown is $20.95, with 30, 60 and 120 capsule sizes selectable. Its pages say a larger size qualifies for Subscribe and Save, at 20% off. Check the price for the size you pick at checkout.

Om’s Master Blend container lists 28 servings. Divide the bottle price on Om’s product page by 28 to get the cost per serving. The coffee is one serving a day. Om’s coffee page says subscription orders ship every 30 or 60 days, and that you can pause, skip or cancel anytime with no phone call. Prices and bundles change, so check today’s price directly with Om.

Side effects, interactions and who should ask a clinician first

Host Defense’s FAQ says that if you are having surgery, have a medical condition, or are taking prescription drugs, including blood thinners or insulin medications, you should consult your health practitioner before taking its products. It also says there is “not enough research available to safely conclude mushroom supplements are safe to ingest during pregnancy or for use by children,” so it does not suggest those groups take its supplements. Its liquid extracts contain 30 to 40% alcohol, per the FAQ.

Om’s Master Blend label says that if you have a medical condition, take prescription medicine, or are pregnant or nursing, you should seek the direction of a qualified health care professional before using it. Its coffee page lists the same groups. Its FAQ adds that you should check with your healthcare provider about any supplement taken alongside prescriptions.

For the coffee, the side-effect question to plan around is the caffeine, at 110 mg per serving.

Refunds, guarantees and shipping

Om’s satisfaction guarantee runs 100 days from purchase, for orders bought directly from its own site. Notify Om by email or phone within that window. Returns must be approved by its customer service team with a return number. Return shipping is paid by the original purchaser, and shipping costs paid at checkout are not refunded. The guarantee does not cover orders where a chargeback has been started, or packages refused or marked “Return to Sender.” Om reserves the right to refuse a refund if abuse is suspected. Its coffee page puts it simply: “If it isn’t right for you, tell us and we’ll make it right.”

For Host Defense’s return terms, call 1-877-504-6926 or email info@fungi.com before you order. Ask for the terms in writing if you want them in hand before you buy. Its shipping policy says orders go by USPS or UPS, turnaround averages 3 business days or less, and only UPS Next Day has a guaranteed transit time.

What do buyers say in reviews?

On Amazon, as of November 2, 2026, Host Defense’s Lion’s Mane listing shows a 4.6 rating from 15,086 reviews, and its Turkey Tail listing shows 4.7 from 7,378. Amazon’s monthly sales estimate for the 120-count Lion’s Mane is about 4,000 bottles. These are the listing’s own figures, not a quality rating. On Host Defense’s site, as of October 6, 2026, MyCommunity shows 5 stars from 9 reviews and Turkey Tail 5 stars from 17. One MyCommunity reviewer says she noticed feeling worse once she ran out and then went on a subscription.

On Om’s coffee page, as of October 6, 2026, there are 398 reviews: 319 at five stars, 38 at four, 21 at three, 8 at two and 12 at one. Two recent reviews are worth reading in full. One verified buyer says the coffee has “not a lot of coffee flavor.” Another says the container was about two-thirds full when it was opened.

Who does each one suit?

• Host Defense suits you if you want capsules, a single-species bottle such as Turkey Tail, Reishi or Lion’s Mane, or the 17-species MyCommunity. It also sells powders and liquid extracts if you prefer one of those.
• Om Mushroom Superfood suits you if you want caffeine in your morning coffee with mushrooms in it, or if you want a daily mushroom powder with ashwagandha. Om’s coffee page says it is “not a sleep or stress product,” and that “if you want to cut caffeine out completely,” it is not the choice.
• Host Defense asks you to check with a practitioner first if you are having surgery, have a medical condition or take prescription drugs, including blood thinners or insulin, and it advises against use in pregnancy or by children. Om asks you to check with a health care professional first if you have a medical condition, take prescription medicine, or are pregnant or nursing.

Before you order: a shelf checklist

• Pick the format you will actually take: capsules, a powder, a liquid extract or a coffee.
• Decide on caffeine (110 mg per serving in Om’s coffee) and ashwagandha (250 mg per serving in Om’s Master Blend).
• Find today’s bottle price and divide it by the servings on that label.
• Buying direct from Om’s site gets you its 100-day guarantee. Read the terms on the page before you check out.
• Call or email Host Defense for its return terms before you order.
• If you take prescription medicine, including blood thinners or insulin, or are pregnant, nursing or having surgery, ask your clinician before you start either product.

On the labels alone, neither brand wins on effectiveness. The format, the caffeine and ashwagandha question, the price per serving and the refund terms you can live with will settle it for you.
