Does RYZE Mushroom Coffee Help You Lose Weight?

Does RYZE actually help you drop pounds, or is it just a nicer morning ritual? That’s the question fans keep asking, and it makes sense. People love RYZE for its smooth energy without the jitters, with about half the caffeine of regular coffee and just 15 calories a cup. The brand started in 2020, when Harvard grads Rashad Hossain and Andrée Werner got fed up with the anxiety and crashes from too much coffee and started blending functional mushrooms into their cups.

RYZE sold online only for its first few years, then rolled into more than 1,900 Target stores nationwide in January 2026. It arrived with three Target-exclusive lattes: Vanilla, Mocha and Caramel. Forbes calls it the best-selling mushroom coffee brand in America, with an estimated $300 million in sales in 2025. With that much buzz, RYZE mushroom coffee weight loss claims are all over your feed, so here’s what’s actually in the cup and what the research says.

What Is RYZE Mushroom Coffee?

RYZE is an instant coffee powder that mixes organic arabica coffee with six functional mushrooms and a blend of prebiotic fibers. You stir one to two tablespoons into 4–6 ounces of hot water or milk, and it’s ready. No brewer needed.

It’s not the same as the mushrooms on your pizza. These are functional mushrooms, chosen for what RYZE says they do for energy, focus, mood and digestion. The blend is vegan, gluten-free, non-GMO and has no added sugar.

What’s in Your Cup

The current Medium Roast has just three ingredient groups:

• Organic instant coffee: Shade-grown arabica from Mexico, brewed and then spray-dried into powder.
• SUPER6 mushroom blend: RYZE’s mix of six organic, US-grown mushrooms:
  • Cordyceps: Included for stamina and steady energy.
  • Lion’s mane: Included for focus and mental clarity.
  • Reishi: Included for stress relief and relaxation.
  • Shiitake: Included for immune support.
  • Turkey tail: Included for gut health and digestion.
  • King trumpet: Included as an antioxidant.
• Prebiotic fiber blend: Acacia, inulin and tapioca fiber, which feed the good bacteria in your gut.

Medium Roast vs. Dark Roast

Both roasts use the same mushroom blend; the biggest difference is the caffeine.

	Medium Roast	Dark Roast
Caffeine	About 48 mg	80–90 mg
Flavor	Smooth and mild	Rich and bold
Mushroom blend	SUPER6	SUPER6
Prebiotic fiber	Acacia, inulin, tapioca	Acacia, inulin, tapioca

Does RYZE Mushroom Coffee Help You Lose Weight?

Not on its own. No human study has shown that mushroom coffee changes body weight by itself, and RYZE doesn’t claim it’s a fat burner. It won’t melt fat, speed up your metabolism overnight or shrink your waistline just by sitting in your mug. Where it can help is the swap. At 15 calories a cup, RYZE is a light replacement for the sugary lattes and creamy coffeehouse drinks many of us grab without thinking. Trade one of those for RYZE every day, and the calories you skip can add up over weeks.

So does RYZE help you lose weight? It can play a small supporting role. The real results still come from eating a little less than you burn, moving more and sleeping well.

How Each Ingredient Could Affect Your Weight

RYZE has only a few ingredients, so it’s easy to look at each one and ask the real question: does any of it actually move the scale? Here’s what the research says.

Caffeine

• What the research says: A 2019 review of 13 controlled trials found caffeine may help lower body weight, BMI and body fat.
• The catch: Those results got bigger as people took in more caffeine. RYZE Medium Roast has about 48 mg, less than half a regular cup of coffee.
• Bottom line: The lower caffeine is great if you get jittery, but it also means you get less of the one ingredient with the strongest weight research behind it.

Prebiotic Fiber (Inulin, Acacia, Tapioca)

• What the research says: A 2024 review of 29 trials found people taking chicory inulin lost about 2 pounds more than those on a placebo.
• Mixed results: An earlier 2021 review found inulin didn’t affect body weight at all.
• The catch: RYZE lists its fibers as one blend, so it’s not clear how much inulin you actually get in a scoop.

The SUPER6 Mushrooms

• King trumpet: Has shown some weight effects, but only in animal studies, not in people.
• Turkey tail: RYZE credits most of the weight loss mentions in its reviews to this mushroom’s prebiotic effect on gut health.
• Reishi and cordyceps: RYZE links these to less stress and more energy for workouts. Those are indirect effects, not fat burning.
• Bottom line: The evidence connecting these mushrooms to fat loss is thin and mostly indirect.

What Happened to the MCT Oil?

• The old formula: Many reviews still say RYZE contains MCT oil and coconut milk, and some credit the MCT oil for keeping you full.
• The 2026 formula: RYZE replaced those with its prebiotic fiber blend in October 2025, and the current Medium and Dark Roast labels list no MCT oil.
• Still in some products: RYZE’s caffeine-free Mushroom Chicory still contains MCT oil powder.
• Bottom line: If you read an article crediting RYZE’s MCT oil for weight loss, it’s describing the old coffee formula.

What RYZE Says About Weight Loss

RYZE is surprisingly upfront about this. On its own blog, the brand says mushroom coffee is not a fat burner. It also admits you probably won’t notice a difference if all you do is swap your regular coffee for RYZE.

Here’s how RYZE frames it:

• It’s a helper, not the solution: RYZE positions its coffee as one small part of a routine built on better food, more movement and good sleep.
• A calorie deficit comes first: The brand says you won’t lose weight without burning more than you eat, and suggests a modest daily deficit of 200–300 calories instead of crash dieting.
• The swap matters most: RYZE recommends using it in place of sugary breakfast drinks, energy drinks or coffeehouse lattes.
• Watch what you add: It suggests skipping sweetened creamers, syrups and whipped cream, which can quickly undo the low calorie count.
• It does break a fast: RYZE notes that its coffee isn’t zero-calorie, so technically it breaks a fast if you practice intermittent fasting.
• Gut health is the angle: The brand ties any weight benefits mainly to gut balance, plus fewer cravings and steadier energy.

RYZE’s site also features customer reviews mentioning weight loss. Those are personal stories, though, not study results.

RYZE Mushroom Coffee Nutrition Facts

RYZE is about as light as a coffee drink gets. Here’s what’s in one tablespoon of the Dark Roast, straight from the label:

Caffeine and Calories by Scoop

RYZE suggests using one to two tablespoons per cup, so your numbers depend on how strong you make it.

	1 Tbsp	2 Tbsp
Medium Roast caffeine	About 48 mg	About 96 mg
Dark Roast caffeine	80–90 mg	160–180 mg

RYZE vs. Your Fall Latte: Where the Real Difference Is

If RYZE helps with weight loss at all, this is where it happens. The mushrooms are a minor factor; the bigger difference is what your morning coffee used to be.

What’s in a Pumpkin Spice Latte

A grande Pumpkin Spice Latte is espresso and steamed 2% milk, topped with pumpkin sauce, whipped cream and pumpkin spice. Only about half of its calories come from the milk and espresso. The rest comes from the sweet sauce and the whipped cream on top.

What’s in a Cup of RYZE

A cup of RYZE is a tablespoon of powder stirred into hot water. With nothing added, it has no sugar and stays at around 15 calories for the Medium Roast. Once you start adding creamer, syrup or sweetened milk, it starts climbing toward latte territory.

Quick Comparison

	RYZE Medium Roast (1 Tbsp, water)	Grande Pumpkin Spice Latte (2% milk, whip)	Black Coffee (8 oz)
Calories	15	390	About 2
Sugar	0 g	50 g	0 g
Caffeine	About 48 mg	About 150 mg	About 95 mg

Swap one grande PSL a day for a plain cup of RYZE, and you skip about 375 calories daily, or roughly 2,600 a week. That’s where a real difference could come from. Black coffee gets you nearly the same savings for less money, so the mushrooms are optional.

How to Drink RYZE If You’re Trying to Lose Weight

A plain cup of RYZE is easy on calories. The trick is keeping it that way and using it to replace something heavier, not adding it on top of your usual latte.

What to Add (and Skip)

Good add-ins:

• Unsweetened milk: Oat, almond or coconut milk adds creaminess without the sugar. Check the label, since many plant milks are sweetened.
• Spices: A dash of cinnamon or cacao powder gives it a cozy fall flavor for almost no calories.
• Zero-calorie sweeteners: Stevia or monk fruit work if you like it sweet.

Better to skip:

• Flavored creamers: Many are loaded with sugar.
• Syrups and whipped cream: These turn a 15-calorie cup into a dessert.
• Big spoonfuls of honey or coconut sugar: They still count as sugar, even if they sound healthier.

When to Drink It

• In the morning: Use it instead of your usual sugary coffee drink or energy drink. That’s where the calorie savings come from.
• Before a workout or walk: The caffeine can give you a light lift without a heavy pre-workout.
• Not during a fast: RYZE has calories, so it technically breaks a fast. Black coffee is the safer choice inside your fasting window.
• Later in the day: RYZE’s caffeine-free Mushroom Chicory is an option if caffeine keeps you up at night.

Keep Your Expectations Realistic

• Give it time: One or two cups won’t change anything. The benefit comes from swapping out higher-calorie drinks consistently over weeks.
• Watch the whole day: A low-calorie coffee won’t offset a big lunch or late-night snacking. Your overall calorie balance is what moves the scale.
• Regular coffee works too: If mushroom coffee isn’t your thing, a good cup of black coffee or one with a splash of milk does the same job for weight loss. You can find freshly roasted beans from independent roasters on Lovers Coffee if you’d rather brew your own.

Side Effects and Who Should Skip It

RYZE is generally easy on most people, but it’s still caffeine plus concentrated mushroom and fiber ingredients. Here’s what to watch for.

Possible Side Effects

• Gas and bloating: Inulin can cause gas, bloating, cramping, constipation or diarrhea, especially if your body isn’t used to much fiber.
• Caffeine effects: Jitters, a racing heart or trouble sleeping can still happen, especially with the Dark Roast or a double scoop.
• Reishi reactions: Reishi has been linked to nausea, dry mouth, dizziness, itching and trouble sleeping in some people.
• Too much caffeine overall: The FDA’s general limit for healthy adults is 400 mg a day. Count your RYZE along with any other coffee, tea or energy drinks.

Who Should Talk to a Doctor First

• Pregnant or breastfeeding: Adaptogenic mushrooms may not be safe during pregnancy or breastfeeding, and the FDA advises checking with your doctor about caffeine too.
• People on blood thinners: Both reishi and cordyceps may raise the risk of bleeding when combined with drugs like warfarin.
• People on diabetes medication: Cordyceps can lower blood sugar, which could add to the effect of insulin or other glucose-lowering meds.
• People on immunosuppressants: Reishi and cordyceps can stimulate the immune system, which may work against these medications.
• People with IBS: Added inulin can make IBS symptoms worse.
• Anyone with a mushroom allergy: Skip it.

The Mug Won’t Do the Math for You

RYZE is a smooth, low-calorie, lower-caffeine cup with a lot of fans, and it’s honest enough to admit it isn’t a fat burner. The mushrooms and prebiotic fiber may do a little for your gut and your energy, but the research linking them to real weight loss is thin. Where RYZE mushroom coffee weight loss results really come from is the swap: trading a 390-calorie fall latte for a 15-calorie cup, day after day, while the rest of your routine does the heavy lifting. If you love the taste and it helps you skip the syrup, it’s a great fit for your morning. If not, a simple cup of black coffee gets you to the same place.
