Does Ryze Coffee Have Caffeine? 48 mg Medium, 80–90 mg Dark
Yes. Ryze Mushroom Coffee is real instant coffee blended with mushroom powder, and it contains caffeine. The medium roast has about 48 mg of caffeine per cup, less than half a standard cup. The dark roast has about 80 to 90 mg, roughly on par with one. Ryze is not decaf, and the brand does not sell a decaf coffee.
Here is a comparison using the numbers Ryze publishes on its own product pages.
| Product | Caffeine per Serving (Brand Figure) | Coffee-Cup Equivalent | Source |
|---|---|---|---|
| Ryze Mushroom Coffee (Medium Roast) | ~48 mg | About half an 8 oz brewed cup | Ryze product page |
| Ryze Mushroom Coffee (Dark Roast) | ~80–90 mg | About one 8 oz brewed cup | Ryze Dark Roast page |
| Standard brewed coffee (8 oz) | ~95 mg | 1 cup (reference) | FDA |
| Ryze's "standard cup" range | 95–200 mg | Varies by brew and size | Ryze comparison page |
Key Takeaways
- Ryze medium roast: about 48 mg caffeine per cup, roughly half of an 8 oz brewed coffee (~95 mg).
- Ryze dark roast: about 80 to 90 mg, close to a full cup.
- Neither product is decaf. If you are cutting caffeine for medical reasons, these numbers matter.
- 48 mg is below the dose used in most alertness trials (75 to 200 mg), so a regular coffee drinker may notice a weaker effect.
Where the Numbers Come From
Ryze states on its product page: "a cup of our mushroom coffee contains about 48mg of caffeine, less than half the amount that's in a regular cup of coffee." That is the medium roast.
For the dark roast, the product page states "about 80-90 mg of caffeine" per cup (1 tablespoon serving, 30 servings per bag). The brand's landing page gives a range of "80-90mg of caffeine per serving." The gap likely reflects lot-to-lot variation in instant coffee, which is why both pages say "about."
Ryze does not publish a third-party lab certificate confirming these figures. These are label statements, not independently verified results.
What "Half a Cup" Actually Means
Ryze's own comparison page puts a standard cup at 95 to 200 mg. That is a wide range. A 200 mg cup is a large, strong brew; 95 mg is closer to the FDA's reference of 80 to 100 mg for 8 oz.
This article uses a standard 8 oz brewed cup at roughly 95 mg as the anchor. Against that:
- 48 mg is about half of 95 mg.
- 48 mg is about a quarter of a 200 mg large coffee.
- 90 mg (dark roast) is about 95 percent of the 95 mg reference cup.
"Half the caffeine" depends entirely on which cup you compare to.
Why Ryze Is Lower in Caffeine
The answer is simple: there is less coffee in the cup.
A Ryze serving is 1 tablespoon of powder containing organic instant coffee, the brand's Super6 mushroom blend (Cordyceps, Reishi, Turkey Tail, King Trumpet, Shiitake, Lion's Mane), and an organic prebiotic blend (acacia fiber, inulin fiber, tapioca fiber). Retail listings put the mushroom blend at 2,000 mg per serving. When a meaningful share of your scoop is mushroom powder and fiber, you get less coffee per cup, and less caffeine follows.
Ryze markets cordyceps as supporting "natural energy," but that is a brand marketing claim, not a measured outcome at the doses in a single serving. For more on what mushroom coffee doses actually deliver, the clinical literature sets a higher bar than most blends meet.
The One-for-One Swap, Worked Out
If you replace your regular coffee with Ryze medium roast, cup for cup, here is where your daily caffeine lands (using the 95 mg reference cup):
- One-cup drinker: 95 mg drops to 48 mg. A cut of about 47 mg.
- Two-cup drinker: 190 mg drops to 96 mg. A cut of about 94 mg.
- Chain-coffee drinker (large espresso-based drink): the drop is steeper. Exact figures vary by chain and size; see how much caffeine is in a shot of espresso for reference numbers.
A two-cup drinker who swaps both cups halves their intake overnight without consciously deciding to cut caffeine. That reduction is enough to trigger withdrawal symptoms.
Ryze's own side-effects page acknowledges this, listing headaches, brain fog, and fatigue when switching from traditional coffee, calling them "usually temporary" and tied to caffeine withdrawal. A 2004 review by Juliano and Griffiths in Psychopharmacology found headache incidence of about 50 percent in caffeine abstinence, with onset at 12 to 24 hours and duration of 2 to 9 days. A half-dose cut is not full abstinence, but the mechanism is the same. See Ryze mushroom coffee side effects for the full timeline.
Can You Drink Ryze at Night?
Caffeine's mean half-life in healthy adults is about five hours, with individual variation from 1.5 to 9.5 hours. Here is what that means for a late-afternoon Ryze:
Medium roast (48 mg) taken at 4:00 PM:
- ~24 mg remaining at 9:00 PM
- ~12 mg remaining at 2:00 AM
Dark roast (90 mg) taken at 4:00 PM:
- ~45 mg remaining at 9:00 PM
- ~22 mg remaining at 2:00 AM
The dark roast at 4:00 PM leaves you with roughly the same caffeine at bedtime as the medium roast gives you at the start. Neither figure is zero. Whether that disrupts your sleep depends on individual sensitivity. Run the numbers for your schedule with the caffeine half-life calculator, or read how long caffeine stays in your system.
Ryze's Other Products
Ryze also sells a Mushroom Matcha (green-tea based, caffeinated; no exact mg figure published) and a Mushroom Hot Cocoa (cacao-based, trace caffeine). The brand launched nationwide at Target in January 2026 with both roasts, coffee sticks, exclusive lattes, and a limited-edition Pumpkin Spice Latte in September 2026. None are decaf.
Is 48 mg Enough to Feel?
Honest answer: it depends on your baseline.
A 2025 systematic review in Nutrition Reviews found that caffeine and L-theanine improved task-switching accuracy across randomized controlled trials, though evidence for subjective alertness was not consistent. But most of those trials used caffeine doses of 75 to 200 mg. At 48 mg, you are below the floor of nearly every trial that measured cognitive performance.
That does not mean you will feel nothing. A person accustomed to a full cup may find the effect mild; someone sensitive to caffeine may still notice it clearly. The FDA considers up to 400 mg per day safe for most adults, so 48 mg is well within range.
Conclusion: Caffeine Counts Are Only Half the Question
Ryze Mushroom Coffee is not decaf. The medium roast contains about 48 mg per cup; the dark roast about 80 to 90 mg. If you are monitoring caffeine for medical reasons, pregnancy, or sleep, those numbers are what to give your clinician. A two-cup drinker switching to Ryze medium roast cuts daily intake roughly in half, enough to cause temporary withdrawal symptoms. The caffeine is real. Plan accordingly.
Frequently Asked Questions
Does Ryze coffee have caffeine?
Yes. Ryze is made with real instant coffee and contains caffeine. The medium roast has about 48 mg per cup; the dark roast about 80 to 90 mg. Ryze does not sell a decaf version.
How much caffeine is in Ryze mushroom coffee?
The medium roast has about 48 mg per serving (1 tablespoon). The dark roast has about 80 to 90 mg. Both figures come from Ryze's own product pages. A standard 8 oz brewed coffee has roughly 95 mg.
Is Ryze coffee decaf?
No. Both roasts contain caffeine. Ryze does not currently sell a decaf mushroom coffee. If you need a truly caffeine-free option, Ryze is not it.
How much caffeine is in Ryze dark roast?
Ryze's dark roast product page lists about 80 to 90 mg per cup. That is roughly equivalent to one 8 oz cup of standard brewed coffee.
Does Ryze have less caffeine than regular coffee?
The medium roast does: about half a standard cup. The dark roast is close to a full cup. "Less caffeine" depends on which roast you pick and what you compare it to. A large chain-coffee drink can exceed 200 mg, so both roasts would be lower than that.
Can I drink Ryze if I am cutting back on caffeine?
Ryze medium roast delivers about 48 mg per cup, a step down from standard coffee's ~95 mg. That makes it lower-caffeine, not zero-caffeine. If you are cutting caffeine for medical reasons, discuss the specific milligrams with your clinician. Expect possible headaches or fatigue during the transition, especially from a multi-cup habit.
If You Wanted Less Ritual, Not Less Caffeine
This article's recurring punchline: Ryze's medium roast gives you 48 mg of caffeine per cup, well below the 75 to 200 mg range most alertness trials test. If what you actually wanted was a simpler format, not a smaller dose, that is a different problem.
Roon is a zero-nicotine oral pouch: 80 mg caffeine, 60 mg L-theanine, 25 mg methylliberine (Dynamine), 5 mg theacrine (TeaCrine). The 80 mg matches the 8 oz reference cup this article used as its anchor. Methylliberine slows caffeine's clearance: a randomized, double-blind, crossover PK study (n=12) found co-administration cut caffeine's oral clearance from 41.9 to 17.1 L/hr and extended its half-life from 7.2 to 15 hours, with no higher peak. That study used 100 mg methylliberine and 150 mg caffeine (roughly 4x and 1.9x what Roon contains), so the magnitude will differ. The directional effect is why Roon's felt window is 6 to 8 hours, and why you should stop at least 8 hours before bed.
From $9.16 per tin on the 12-tin subscription ($0.61 per pouch), or $15.00 one-time for 4 tins ($1.00 per pouch), against Ryze's $1.20 to $1.50 per serving. Nothing to brew, nothing to drink, zero sugar. Roon is not a mushroom product and will not replace whatever the mushrooms are doing for you. If the caffeine dose is the part you care about, try Roon.
