No matter what products I tried, I just couldn’t seem to deal with all that sugar. They all tasted okay and seemed to go down okay, but my stomach would always be on the edge of throwing up 20 minutes after. I found MAS Flush from a podcast I listen to and thought maybe it would help. It worked almost right away, I was a little surprised. I’m still cautious, but this seems to have done the trick.

I tried this product during the beta launch because I really struggled with stomach pain when racing and even after hard workouts. There were times after hard workouts that it would take hours for my stomach to feel normal. MAS Flush changed everything. I’ve been using it for a month and I haven’t had any stomach pain after workouts. I’m so glad I found this.

I’ve had some of my best races ruined when I took a gel in the middle of the race and couldn’t seem to keep it down. I wasn’t sure how a probiotic could really help with that, but I gave this a shot anyway. My last two races I haven’t had any issues even though my last race was pretty warm. Feels good to have the confidence I might have kicked this issue.
Revolutionary Ingredients Backed by Science
MAS Flush is more than just a probiotic. We’ve carefully chosen the specific strains of bacteria and yeasts proven to help the most for athletes. Then we combined them with cutting-edge ingredients that help improve all the unique aspects of gut health runners and endurance athletes face.
Psyllium, derived from the plants known as ispaghula, is a primarily soluble, bulk-forming fiber supplement shown in research to help improve digestive and metabolic health.
Compared to similar fibers, psyllium is less fermentable in the gut, which means it’s less likely to produce flatulence, stomach pain, and nausea.
Research has demonstrated that psyllium makes bowel movements easier and more consistent which can help alleviate the issue of runner’s trots by ensuring you’re able to go to the bathroom before your run1.
Psyllium has also been shown in research can help add bulk to stool, which helps relieve the feeling of needing to go to the bathroom. This is especially helpful due to the jostling that occurs in the digestive tract during running.

Bifidobacteria are a type of probiotics, which are healthy bacteria found in your intestines that help digest fiber, prevent infections, and produce important compounds, such as B vitamins and healthy fatty acids.
One of the main functions of bifidobacteria is to digest fiber and other complex carbs your body can’t digest on its own, which can lead to bathroom issues.
Specifically, bifidobacteria supplementation has been shown in research to significantly lower the incidence and severity of GI symptoms in marathon runners1.
Research has also shown that runners who supplemented with bifidobacteria saw a reduction in the severity of GI symptoms during training2 as well as a reduction in the duration of GI symptoms post-race3.

One of the most common reasons runners experience bathroom issues later into runs and races is due to internal and exertional heat stress. This is because blood is redistributed away from the digestive system to help with thermal regulation.
As a result, lack of blood supply stresses the gut, which results in bathroom and stomach issues.
Recent research has shown that New Zealand blackcurrant…
- Reduces total gastric distress symptoms by 73% in runners1.
- Reduces ‘leaky gut’ by up to 40%2

Fueling your training properly means you have to digest and absorb the foods you eat, but this can be difficult for a number of reasons.
First, the foods that fuel our training are often difficult to digest, such as plant fibers, starches, and proteins.
Second, after hard training blood is still being shifted away from the stomach to aid in muscle recovery, which leaves fewer enzymes available to break down your meals. This is why you’re often not hungry for hours after hard workouts.
Our enzyme blend is specifically designed to target the foods endurance athletes need the most and are most difficult to break down.
Protease 500,000 HUT/g – helps break down proteins into absorbable amino acids
Amylase 100,000 DU/g – splits starches into usable glucose
Lipase 15,000 FIP/g – breaks fats into fatty acids for sustained energy
Cellulase 150,000 CU/g – shreds tough plant fibers your body can’t process alone.
The result is faster, more complete digestion that delivers more building blocks to recovering muscles while keeping your gut calm and race-ready.
Hard running diverts blood away from your gut, loosening the tight seals between intestinal cells and letting bacteria leak into your bloodstream.
Your immune system responds with inflammation, which triggers cramping, bloating, and nausea.
Lactobacillus acidophilus reinforces those cellular seals before they fail.
This specific probiotic strain crowds out harmful bacteria, tightens the gaps in your intestinal lining, and quiets the inflammatory response.
Research shows that supplementing daily for at least four weeks reduces GI symptom severity during long efforts and cuts down on emergency bathroom stops mid-race.
Hard training temporarily weakens your gut lining, allowing inflammatory compounds to leak into your bloodstream and suppress your immune system.
This is why runners tend to catch the cold and flu more when training hard.
Bifidobacterium animalis helps seal these gaps and strengthen the gut lining to prevent these inflammatory compounds from entering the blood stream.
It also helps cultivate and prime virus fighting cells so your body is more capable of fending off the pathogens that cause getting sick.
Consistent supplementation helps you spend less time recovering from illness and more time building fitness.
MAS Flush Vs. Generic Probiotics
While almost any probiotic will help improve your gut health, you have unique challenges and needs as a runner that generic probiotics just don’t address.

the end of fueling & GI Issues
here's what MAS Flush Can Do for You
Stop Worrying About Carrying Toilet Paper or Finding Place to Hide
Every runner fears starting a run without nearby bathrooms.
Frequent needs to go to the bathroom early in a run are usually caused by not being able to quickly digest the foods you ate for dinner or when your digestive system isn’t able to keep up and you have inconsistent bathroom times.
MAS Flush contains Psyllium seed husks, which when taken in the evening helps make bowel movements easier and more consistent.
It can also help add bulk to stool, which helps relieve the feeling of needing to go to the bathroom. This is especially helpful due to the jostling that occurs in the digestive tract during running.
Taking just two MAS Flush capsules after dinner will make it easy to go to the bathroom as soon as you wake up so you can virtually eliminate needing to go to the bathroom during your runs.
Eliminate stomach pain during and after races
Put an end to stomach pain and cramping during and after hard workouts that lead to you slowing down and not getting the most from your performance.
Stomach issues during races and hard workouts often happen for two reasons.
First, endotoxins (bacterial toxins) are released during strenuous, long-duration exercise which lead to cytokine release, oxidative stress, and altered gastrointestinal function.
Second, internal and exertional heat stress causes blood to be redistributed away from the digestive system to help with thermal regulation. As a result, lack of blood supply stresses the gut, which results in bathroom and stomach issues.
MAS Flush’s combination of Bifidobacterium Longum and Blackcurrant have been shown in research to
- Reduce total gastric distress in runners by 73%
- Reduce endotoxin unit levels during races
- Reduce the duration of GI symptoms post-race
Fix Bloating & Digestive Issues While Absorbing More of the nutrients you consume
Bloating and digestive issues occur more often in endurance athletes because the fuel we need to train and recover often comes from difficult-to-digest foods such as plant fibers, complex carbohydrates, and proteins.
Usually, this is caused by not producing enough of the enzymes that help break down these foods.
Our endurance-focused digestive enzyme blend is specifically designed to help your body naturally digest the foods you need to fuel your training while improving your gut microbiota to create a more favorable environment in your stomach.
The enzymes in MAS Flush have been shown in research to…
- Break down food and extract nutrients, making it easier for the body to absorb.
- Improve the integrity of the gut lining, which helps prevent the leakage of undigested food particles (often called leaky gut) and enhances nutrient absorption.
- Reduce gut inflammation to increase the absorption of micronutrients like calcium and iron.
No more stomach issues taking gels and other carbohydrates during your race
One of the most difficult things about racing half, full and ultra marathons is taking in enough fuel to keep your glycogen levels topped off without causing stomach issues.
All that simple sugar is difficult for your body to process quickly, which is a main contributor to why many runners suffer to fuel properly during races.
The included Bifidobacterium in MAS flush has been shown in research to improve carbohydrate absorption and metabolism during endurance races, potentially sparing muscle glycogen during prolonged exercise.
Additionally, Bifidobacterium may help maintain gut barrier integrity, reduce gastrointestinal distress, and improve nutrient absorption.
Eliminate post workout stomach issues so you can refuel easier
There’s a reason we often refer to hard workouts as “gut-busting”. That’s because they often leave us with stomach discomfort after the workout.
This happens because after a hard training run, blood is still being shifted away from the stomach to aid in muscle recovery.
This leaves fewer enzymes available to break down your meals.
It’s also why you’re often not hungry for hours after hard workouts.
The digestive enzymes in MAS Flush have been shown in research to reduce post-workout stomach discomfort so you can jump start your recovery process with the nutrients your muscles need.
Reduce The Occurrence of Colds and other immune issues
Hard training temporarily weakens your gut lining, allowing inflammatory compounds to leak into your bloodstream and suppress your immune system.
This is why runners tend to catch the cold and flu more when training hard.
The probiotics in MAS Flush help seal these gaps and strengthen the gut lining to prevent these inflammatory compounds from entering the blood stream
It also helps cultivate and prime virus fighting cells so your body is more capable of fending off the pathogens that cause getting sick.
Consistent supplementation has been shown in research to help you spend less time recovering from illness and more time building fitness.

your questions answered
Experience the benefits of a healthy gut, better digestion and no more bathroom fears
Can I or Should I Take MAS Flush Every Day?
MAS Flush works best if you take it every day.
In addition to alleviating bathroom issues before and during running, the probiotics in MAS Flush help you more efficiently digest foods, absorb nutrients, and create a favorable environment for the growth of “good microflora” in the large intestine.
That said, if you only wanted to use on the days you run for the improvement of bowel movements, it will still work great.
Should I take MAS Flush Before a Race?
Like almost any product, you should definitely use MAS Flush a few times during your training cycle before using it during a race.
The most significant results and changes often occur during the first few uses as your gut and digestive system experience ingredients for the first time.
However, we did specifically formulate the product to help with many of the digestive challenges we face during the race so it should be a significant aid during your most important performances.
Is MAS Flush Safe to Take With Other Probiotics?
Yes, MAS Flush is safe to take with any other probiotic or gut health product you may be taking.
The current medical literature has found that it’s difficult to overdose on probiotics or experience dangerous side effects from a large dose of probiotics.
Will I Experience Any Side Effects?
You should not notice any side effects when taking MAS Flush.
That said, the most significant results and changes often occur during the first few uses as your gut and digestive system experience ingredients for the first time.
This means your bowel movements the first evening and the morning after you’re your first few doses may be more noticeable than they will be as you continue to use the product.
When Is the Best Time to Take MAS Flush?
MAS Flush should be taken in the evening, ideally after your last meal.
That’s because one of the main ingredients, psyllium husks, takes at least a few hours take effect in the bowels.
This means that when you take it in the evening, it should make it easier to go to the bathroom as soon as you wake up. In addition, it helps improve bowel movements so you evacuate more during this first bathroom visit, making sure you don’t need to go as you start your run or during.
I Have X Condition, Is MAS Flush Safe for Me?
Probiotics and the ingredients in MAS Flush are generally considered safe, but if you have any concerns you should definitely contact your healthcare professional first.

I have no angst about intestinal issues. THANK YOU. 5 STARS
For 20 years, I planned every run around where I would have a bathroom. For group runs, I would arrive 20 minutes early to be sure I could do the group run without stopping. If, on a run, I couldn’t find a bathroom within 1 – 1.5 miles from the start, I would have “an issue.”Terrible. Embarrassing and uncomfortable.Then, I started using MAS Flush. After about 3 days of using the supplement, I would wake up, use the bathroom and the runs would go off with no interruption. No problem.OMG. This was a game changer for me. Now, I take the supplement at night and in the morning, I have no angst about intestinal issues. THANK YOU. 5 STARS.

I’m now a believer in this product.
I’m a 74 year old runner. I noticed that over the last several months every run brought about some horrible feelings with my digestive system with unfortunate results.I realized my stomach issues occurred after running about three miles. I read about MAS Flush used it and have had amazing results. This product has had some positive effects on my recovery period.I have used several different brands but never had the results that this one has had. As a result I had very little confidence in any product. Now I do trust in this company and product.

I’ve only been using it for a short time but so far so good!
I was a little skeptical because there’s so much hype in advertising and it can be hard to trust that anecdotal endorsements are real. But I was desperate so decided to try it. I had tried Probiotics and soluable fiber before but they did not improve running GI events. Taking a few capsules at bedtime seems to be really effective in preventing my emergency GI issues while running. I’m pretty excited about that! Planning run routes around bathroom availability, stopping in corn fields or phoning for emergency pickup has been my run training history for years. Almost quit the sport. I’ve only been using it for a short time but so far so good!

Surprisingly effective
Honestly, I wasn’t expecting much. The first few days I think I may have even felt worse. Then one morning it felt like everything kicked in and I had more energy, my bathroom visits have been surprisingly regular, and I feel much better after my runs. I didn’t even realize having an queasy stomach wasn’t normal after long runs. Thank you so much!

Stomach issues gone
The biggest surprise for me was how much calmer my stomach feels. I used to deal with post-run stomach pain, almost to the point where I couldn’t eat for hours after a hard run. Now everything feels much more stable and predictable. That alone makes it a win.

MAS Flush works for me
When I run, I normally, after 10-15 minutes, have to make a pit stop. When I do long runs I, many times, have to stop 2-3 times. Since starting to use, MAS Flush, I still schedule in the stop after 10-15 minutes but then I am fine: 100%. About half the time, I don’t have to stop because I was able to empty out before the run.

Truly, a game changer !!
Just wanted to check in and let you know that it’s been 1 month since I’ve started taking MAS FLUSH and during the 18 runs which I’ve done since, I have not had the urge of a bowel movement while running !Keep in mind that this is coming from someone who, in my 9 years of running, I don’t think that I’ve ever gone 3 (maybe 4) consecutive runs without having to stop to poop.Truly, a game changer !!As I mentioned before, I had kind of resigned myself to living with this unfortunate & uncomfortable condition and I really can’t believe that I have found a solution !A huge thanks to you & MAS FLUSH !

sounds too good...but it works
This supplement transformed my running! I know that sounds over the top but it really did. Without fail my stomach would always start churning late in races and slow me down and I almost always had bathroom issues after really hard workouts. It took a week or two to really kick in but all those are virtually gone now. I’ve only raced once but I never got that stomach churning feeling and I was right on my PR despite being in marathon training. Thank you so much, this is awesome!

highly recommended
I must say that I was skeptical at first. The first day or two I didn’t feel much. However, I continued to use this product and felt less indigestion with a feeling of being less bloated as well. I recommend flush to those who have a sensitive stomach like mine and looking to settle their stomach during hard workouts. 5 stars!

Nothing else I tried helped
For an unknown reason, for the last months I needed bathroom stops too often during my early morning runs. This was a new thing and I could not explain it as nothing changed as far as I know. I came across MAS Flush through a running related newsletter and decided to give it a go as nothing else I tried had helped. I was so surprised and impressed that my issues faded after just a few days of taking MAS Flush! 95% of the time I don’t have emergency stops now. I just need to make sure to give myself about an hour as it causes 2-3 bowel movements.

Thank you
I honestly can’t believe this product worked so well. Before using flush, I’d be scrambling back home to go to the bathroom at least 3 days per week. It made me scared to go to group runs or even try out new trails for fear of not having a bathroom nearby. I’ve been using for 3 weeks now and not once have I had to go to the bathroom once I started running. This is such a relief!

Love the routine
I love how regular this makes my morning bathroom routine. I used to fear the mornings I’d wake up and not need the bathroom since I knew it was going to happen on the run. Since starting Flush I am so much more regular in the morning and it’s such a relief
