Ryze Mushroom Coffee Review 2026: Ingredients, Caffeine, Price & Side Effects

How this review was put together: it is based on Ryze’s own product listings and help pages (checked October 2026), regulatory and court documents, and NIH and Memorial Sloan Kettering summaries of the research. We did not run a tasting panel, and flavour descriptions below are Ryze’s or its customers’, not ours.

What Is Ryze Mushroom Coffee?

Ryze is a Boston-based brand founded by Andrée and Rashad, who say they created it after their own coffee habit left them feeling anxious and unsettled (Ryze). The product is a powder you stir into hot water or milk, like instant coffee, sold mainly by subscription from Ryze’s website.

What Makes Ryze Different

According to Ryze’s ingredient list, updated on 22 September 2026, the Medium Roast contains three things (Ryze ingredient list):

• Organic instant coffee: shade-grown organic Arabica from Mexico, spray-dried into powder (Ryze ingredients page).
• Ryze Super6™ mushroom blend: cordyceps, reishi, king trumpet, shiitake, turkey tail and lion’s mane. Ryze says its mushrooms are organic and grown in California.
• Organic prebiotic blend: acacia, inulin and tapioca fiber.

The Dark Roast uses the same mushroom and fiber blends with a different instant coffee: Ryze says it combines Arabica and Robusta, contains 2,000 mg of the Super6 blend per serving, and is not entirely certified organic, although all the mushrooms are (Ryze Dark Roast).

Lion’s Mane for Brain Power

Ryze markets lion’s mane “for focus and clarity.” Laboratory research reviewed by Sabaratnam and colleagues suggests compounds in the mushroom may stimulate nerve growth factor (NGF), but human trials so far are small, and NIH’s LiverTox entry treats its memory and mood benefits as unproven.

Reishi for Stress Relief

Ryze says reishi “helps support stress relief, balance mood, and promote deep, restful sleep.” Reishi is marketed as an adaptogen, meaning something said to help the body cope with stress, but good human evidence for that is limited. Memorial Sloan Kettering notes reishi can increase bleeding risk and advises talking to your doctor if you take blood thinners or immunosuppressants (MSK: Reishi).

Cordyceps for Energy Without the Crash

Ryze says it relies on cordyceps rather than caffeine to “sustain energy naturally.” Human research on cordyceps is limited, and the simplest explanation for a gentler feel is the lower caffeine dose: 48 mg in the Medium Roast versus roughly 95 mg in a typical brewed cup.

Turkey Tail and Shiitake for Gut Health and Immunity

Ryze positions turkey tail for gut health and shiitake for immune support, alongside the prebiotic fibers. (An earlier version of this review listed chaga, which is not in Ryze’s current blend.) Turkey tail and shiitake have mostly been studied for immune effects in cancer research, and there isn’t good evidence that a daily cup improves gut health or immunity in healthy people.

What the Science Actually Says

Most research on these mushrooms comes from lab and animal studies plus a handful of small human trials. NIH’s National Cancer Institute states that “the FDA has not approved the use of medicinal mushrooms as a treatment for cancer or any other medical condition” (NCI PDQ: Medicinal Mushrooms). Ryze’s own site carries the standard notice that its statements “have not been evaluated by the Food and Drug Administration” (Ryze). The fair conclusion: buy it as a lower-caffeine coffee, not as medicine.

Customer Reviews

Ryze’s product page shows a 5-star average across 220,391 reviews (October 2026), with featured testimonials praising energy, focus and taste (Ryze). Keep in mind that these ratings are hosted and curated by the brand itself, not an independent reviewer, and that they are self-reports. Some customers dislike the taste or find the effects subtle. As with any supplement-style product, results vary.

Flavor and Preparation

Ryze describes the Dark Roast as “full bodied and robust” and “rich with chocolate notes.” For the Medium Roast it emphasises a lower-acid Arabica base. It’s an instant powder, so texture is closer to instant coffee than to brewed or espresso, and Ryze suggests adding milk, creamer or a frother for a creamier cup.

Data Behind the Shift

• Caffeine: Ryze says a cup of Medium Roast has about 48 mg of caffeine, “less than half the amount that’s in a regular cup of coffee,” and the Dark Roast about 80–90 mg (Ryze; Dark Roast page).
• What else is in the cup: the six-mushroom blend and prebiotic fibers. Older formulas and some of Ryze’s FAQ text still mention MCT oil; the current Medium Roast ingredient list doesn’t. Whether the mushroom extracts do much at this dose hasn’t been shown in good human trials.
• Digestibility: lab and animal studies suggest some functional mushrooms have anti-inflammatory effects, but that hasn’t been shown to translate into better digestion from a daily cup. Less caffeine may simply be easier on some stomachs.

How to Prepare Ryze

Ryze’s directions for the Medium Roast (Ryze):

1. Add 1–2 tablespoons of Ryze to a mug.
2. Dissolve it in 4–6 oz of hot water or milk.
3. Add creamer or sweetener to taste, froth if you like, and drink.

For the Dark Roast, Ryze suggests 1 tablespoon in 4–6 oz of hot or cold water (Ryze Dark Roast).

Comparing Ryze to Regular Coffee

Ryze Mushroom Coffee Side Effects

• Caffeine effects: 48 mg is modest, but caffeine-sensitive people can still feel jittery or sleep badly, and the Dark Roast has nearly double that.
• Gas or bloating: the blend contains inulin and other prebiotic fibers, which can cause gas or bloating in some people, especially at first.
• Allergy: skip it if you’re allergic to mushrooms.
• Pregnancy, breastfeeding and medication: there’s little safety research on mushroom extracts in these groups. Ryze itself recommends “consulting with your physician before repeated use,” and MSK flags possible interactions for reishi with blood thinners and immunosuppressants.
• Liver: NIH’s LiverTox describes lion’s mane and cordyceps as generally well tolerated, while reishi has rare reports of liver injury (Lion’s Mane, Reishi, Cordyceps).

Ryze in 2026: Claims, Lawsuits and Regulators

• Advertising claims dropped (2025): after an inquiry by BBB National Programs’ National Advertising Division, Ryze permanently discontinued claims that its Mushroom Coffee provides “all-day energy, sharper focus, healthier digestion, [] better immune support” and “better sleep.” NAD didn’t rule on the merits because the claims were withdrawn (BBB National Programs, 11 Sept. 2025).
• Class action over pricing (2026): a federal class action filed on 5 June 2026 in the Central District of California (Beltran v. Ryze, Inc., No. 2:26-cv-06091) alleges a false-discount scheme and violations of California’s Automatic Renewal Law (complaint). These are allegations, not findings.
• What it means for you: the single bag on Ryze’s site comes with a US$36 refill that ships every 30 days, so check what you’re signing up for. Ryze says you can adjust shipments or cancel anytime and offers a 30-day money-back guarantee (Ryze).

Where to Buy

Ryze sells mainly through its official website, which ships within the US only. In October 2026 a 30-serving bag (Medium or Dark Roast) was US$27 on sale against a US$45 list price (US$0.90 a serving), with a US$36 refill every 30 days; the 60-serving Starter Kit was US$49.50 and the Ritual Set US$57.60, both about US$0.82 a serving. Prices change with Ryze’s frequent sales (Ryze). It costs more per cup than brewing your own coffee from beans.

FAQs

Does Ryze have caffeine?

Yes, but less than regular coffee. Ryze says its Medium Roast has about 48 mg per serving and the Dark Roast about 80–90 mg, compared with roughly 95 mg in a typical brewed cup.

Can I drink Ryze daily?

For most healthy adults, one or two servings is a modest amount of caffeine. There is no long-term safety research on Ryze itself. If you are pregnant, breastfeeding, take blood thinners or immunosuppressants, or have liver problems, check with your doctor first.

Does Ryze taste like mushrooms?

Ryze and many of its customers say it doesn’t; the brand describes its coffee as smooth, and the Dark Roast as robust with chocolate notes. We have not run our own tasting.

Is Ryze vegan, gluten-free and keto-friendly?

Ryze labels its coffee vegan, gluten-free and keto-friendly and says all its ingredients are vegan and gluten-free, but it also says it is still working on formal gluten-free and vegan certification.

Is Ryze better than regular coffee?

It depends on what you want. If you want a gentler, lower-caffeine instant cup, the Medium Roast is worth trying. If you want strong caffeine or the best flavour per dollar, brewed coffee wins. Don’t buy Ryze expecting proven health benefits.

Can I cancel a Ryze subscription?

Ryze says you can adjust shipments or cancel anytime and offers a 30-day money-back guarantee. Check your order carefully, because the default single-bag purchase includes a US$36 refill every 30 days.

Verdict

Ryze is a pleasant, convenient, lower-caffeine instant coffee with a strong subscription push. Judge it as a cup of coffee: if a 48 mg instant drink at about US$0.90–$1.20 a serving suits your routine, it is worth a try under the 30-day guarantee. Treat the mushroom benefits as unproven, read the subscription terms before you check out, and if your real goal is less caffeine, compare it with simply drinking decaf or a smaller cup.
