The Science Behind It
Turkey Tail (Trametes versicolor) contains complex polysaccharides that have been studied for their prebiotic effect on the gut. That matters for your digestion, because when the bacteria in your gut fall out of balance, the ones that don't belong can irritate and inflame the intestinal lining. That inflammation is what drives the bloating after meals, the unpredictable bathroom trips, and the feeling that your stomach just isn't working right.* Turkey Tail feeds the beneficial bacteria that keep that lining healthy and calm. That's why we use the whole growing mycelium together with the brown rice it ferments, instead of a thin powder. Every two-capsule serving delivers a full 1,000 mg, so each dose is potent and consistent.

Frequently Asked Questions
How long until I see results? Most people report noticeable changes within 2 to 4 weeks of daily use, especially less bloating after meals and more predictable digestion. Some notice it sooner, but consistent use is essential. Give it a full bottle.*
What's the correct dosage and how should I take it? Follow the label, typically 2 capsules daily. Take them with food or without, at whatever time you'll remember. Consistency matters more than timing.
Is it safe to take with medications? If you take prescription medication or have a health condition, speak with your doctor before starting. Marra is a whole-food mushroom supplement, not a drug, and it is not intended to replace anything your doctor has prescribed.

Unlike many brands that throw a blend of random probiotic strains at the label, we use one ingredient at a full dose: 1,000 mg of whole Turkey Tail mycelium and fermented biomass, aimed at supporting the gut lining where digestion actually happens. No fillers, no fluff, just a formula built to do one job well.*

Every Ingredient Carefully Chosen
Every ingredient in our formula is there for a reason, and backed by peer-reviewed research, not marketing fluff. We don't hide behind proprietary blends or vague labels. You get a clear, transparent list of what's in the capsule, included at a meaningful dose.
Turkey Tail Mycelium
Gut Lining Support
Turkey Tail Mycelium
Gut Lining Support
Turkey Tail (Trametes versicolor) provides complex polysaccharides, the compounds studied for their prebiotic effect on the gut. By feeding the beneficial bacteria that maintain the intestinal wall, it supports a healthy gut lining and a balanced bacterial environment, which is what comfortable, predictable digestion depends on.*
Fermented Brown Rice Biomass
Full-Spectrum Delivery
Fermented Brown Rice Biomass
Full-Spectrum Delivery
The mycelium is grown on organic brown rice and ferments it as it grows. We keep that fermented biomass in the capsule instead of stripping it out, because that is the form the ingredient has been studied in and it is what makes the full 1,000 mg serving complete.
Pullulan Capsule
Clean Delivery
Pullulan Capsule
Clean Delivery
Pullulan is a plant-derived capsule made by fermentation, so the whole product stays vegan, gluten free and free of gelatin. Nothing else goes in. No fillers, no binders, no flow agents, just the active ingredient and the capsule that carries it.
What Sets Our Turkey Tail Apart?
Most gut supplements on the market sound the same, but there are critical differences that affect how well they work in your body. Here's why ours stands out:
Clinically Effective Dosage
We don't just sprinkle in Turkey Tail for the label. Every two-capsule serving delivers a full 1,000 mg of mycelium and fermented biomass, the whole growing organism rather than a pinch of powder, so the dose is meaningful and consistent.
Aimed at the Gut Lining
Most digestive supplements throw random strains at the problem without addressing what's actually causing the discomfort. Turkey Tail's prebiotic activity feeds the bacteria that maintain your intestinal wall, the lining that decides whether your stomach stays calm or blows up after every meal.*
Sustainably Sourced
Our Turkey Tail is grown on certified organic brown rice and delivered whole, without solvent extraction, fillers, additives, or artificial preservatives you'll find in cheaper alternatives. Made in a GMP-certified facility.

What Real Customers Are Saying
I used to dread eating after 5pm because my stomach would just blow up every single time. Around week three I ate pasta and just sat there waiting for it. Nothing happened. I almost cried. Two capsules with breakfast, that is all I changed.
My husband noticed before I did. He said I stopped unbuttoning my jeans after dinner. I had been doing it so long I did not even realize it was a thing. About six weeks in and my stomach just feels quieter. Less gurgling, less bloating, less running to the bathroom after every meal.
I used to map out every bathroom before leaving the house. That is not an exaggeration. About two months in and I can get through a morning without thinking about it. My doctor said keep doing whatever you are doing. So I am.
I have tried every probiotic, every enzyme, every elimination diet. My cabinet looked like a pharmacy. This is the first thing that actually made a difference I could feel. Less bloating, more regular, and I did not have to cut out every food I enjoy.
My kids used to joke about how bloated I looked after dinner. Real funny. Eight weeks in and I eat the same food as everyone else at the table and my stomach stays flat. My wife made me order three more bottles because she does not want me to run out.

What makes this gut supplement different?
+
Unlike many brands that throw a blend of random probiotic strains at the label, we use one ingredient at a full dose: 1,000 mg of whole Turkey Tail mycelium and fermented biomass, aimed at supporting the gut lining where digestion actually happens. No fillers, no fluff, just a formula built to do one job well.*
Does Turkey Tail really help with bloating?
+
Turkey Tail has been studied for its prebiotic effect on gut bacteria. When those bacteria are balanced and the gut lining is healthy, digestion runs the way it's supposed to, which means less of the bloating, discomfort and unpredictable bathroom trips that come from an irritated gut.* Individual experiences vary.
Why does the gut lining matter for digestion?
+
Your intestinal wall is the barrier between the food you eat and how you feel after. When the bacteria in your gut fall out of balance, the lining gets irritated and inflamed, and that inflammation is what drives bloating after meals, gas, and irregular digestion. Turkey Tail feeds the beneficial bacteria that keep that lining calm.*
How long until I see results?
+
Most people report noticeable changes within 2 to 4 weeks of daily use, especially less bloating after meals and more predictable digestion. Some notice it sooner, but consistent use is essential. Give it a full bottle.*
What's the correct dosage and how should I take it?
+
Follow the label, typically 2 capsules daily. Take them with food or without, at whatever time you'll remember. Consistency matters more than timing.
Are there any side effects?
+
Turkey Tail is well tolerated by most people. A few may notice mild digestive changes in the first week as the gut adjusts, which usually settles on its own. Always follow directions.
Is it safe to take with medications?
+
If you take prescription medication or have a health condition, speak with your doctor before starting. Marra is a whole-food mushroom supplement, not a drug, and it is not intended to replace anything your doctor has prescribed.
How is this better than regular probiotics?
+
Most probiotics throw ten or twenty strains at the problem and hope something sticks. They don't address the gut lining itself. Marra uses Turkey Tail mycelium to feed the bacteria already in your gut so they can maintain the intestinal wall, which is where the real problem usually is. Full 1,000 mg per serving, made in a GMP-certified facility.
Do I have to change my diet?
+
No. The formula supports the gut environment itself, not a specific food reaction. Most people find they can eat more comfortably without cutting out the foods they used to avoid.*
