I've had IBS-C for 30 years

I've had IBS-C for over 30 years now. NOTHING was working. The doctors tried everything to see if they could help my pain and stomach problems. About 1 month ago, I discovered this product online. My husband said try it! It's worth the money if it works. It works! I started taking them not quite 3 weeks ago and l've had normal BM since! I kid you not, no cramps, no sweating since. Try it, I'm praying it works for everyone else!

I been to doctors multiple times for stomach issues over past two years if not more feeling dizzy, no energy to do anything, I couldn't poop right ever. I tried probiotics, fiber drink, medicine from doctor for acid reflex in stomach and one day I came across this on my facebook feed. Best decision I made I'm 28 days in using this and I feel so much better. I'm actually wanting to do things after work now and not just sleep all the time. My intermittent dizziness is gone and my stomach aches are gone.

Bloating down 90%

I’ve had so many stomach issues for the past year, running to the bathroom, bloating and just feeling horrible. I went to my Doctor and was prescribed medicine for IBS and nausea, it helped a little. Then one day out of the blue I saw Best Days, I read a bunch of the reviews and thought this is something I need in my life, reading all the stories...I couldn't believe how many people are going through the same thing! Within the first week I was amazed how much it has helped. I've been taking it for nearly 4 weeks now and now I've got my friends ordering it too! This product is AMAZING! Thank you

Recent studies reveal…

PROBLEM

When You’re Anxious Or Stressed Out, Your Digestion Shuts Down...

Illustration of brain and digestive system with an 'OFF' switch below.

👉 It all has to do with a primal 'Fight or Flight' reflex we still have.


When it kicks in, your body shuts down anything non-essential, like digestion, to focus all your energy on surviving.

Your body releases Cortisol, which is our “stress hormone.”

Diagram of the human digestive system with an icon representing the intestines and digestive process.

Cortisol Disrupts Your Gut's Rhythm

Some days, you're stuck on the toilet, straining to pass hard, pellet-like stools that won't budge. Other days, it's the opposite - sudden, urgent diarrhea has you sprinting to the bathroom multiple times, passing loose, watery stools.

Illustration of human intestines with bowel movement in feces representation and odor.

Food Gets “Stuck”, Causing Bloating & Gas

Meals sit like rocks in your gut, fermenting and creating embarrassing gas that escapes at the worst possible moments. Your abdomen feels tight and distended, and no amount of stretching or moving seems to provide relief.

Illustration of an inflamed human large intestine with red lightning bolts indicating pain.

Your Gut Becomes A Hypersensitive Mess

Pain signals from your gut to your brain get amplified. Result: Mild sensations become stomach aches. Slight pressure feels like intense cramping. This hypersensitivity can turn eating into an uncomfortable experience, as your body overreacts to the normal process of digestion.

Illustrated human intestines with a burger, pizza, and exclamation marks inside.

You Can’t Tolerate ‘Hard-To-Digest’ Foods Anymore

Dairy products lead to painful bloating and urgent trips to the bathroom. Gluten-containing items like bread and pasta leave you feeling sluggish and crampy. High-fat meals sit in your stomach like a rock, causing acid reflux and discomfort for hours.

INTRODUCING...

The ONLY Smart Formula That Activates Your Body's Natural Rest & Digest Mode

👉 By boosting the natural production of Serotonin, your ‘Feel-Good’ Hormone.

Your GI Tract Gets 6x More Blood Flow During 'Rest & Digest'

👉 Your gut gets a surge of oxygen and nutrients. This boost in circulation energizes your digestion, making it easier to process food and keep your intestines healthy.

Your Pelvic Muscles Relax, Letting Poop Exit Easily And Completely

👉 When you're stressed, these muscles get tight. This makes it hard to poop, like squeezing through a narrow tube. But when you're relaxed, these muscles loosen up. This lets your poops practically slide out with ease. This is the KEY to those COMPLETE poops that leave you feeling empty and clean.

This has changed my life.

I have been taking this for 3 months now. I take 1 in the morning and 1 at night due to how severe my irritable bowel syndrome is. I can eat everything now and have no side effects. I used to have diarrhea, bloating, stomach cramps, and bad gas every time I ate gluten, dairy, spicy foods, onion, garlic, and coffee. I've suffered from IBS for 8 years. This has changed my life.

Works Fast

Within days of taking these pills I feel tons better. The not as noticeable, mild discomforts were the first to go. Then I found that the pain that comes from stress triggers was almost completely gone. The longer I took these pills, the better it got. I also found I could incorporate many more foods (in small quantities) back into my diet that I could never even consider eating before. When I am good about taking these consistently, I feel normal. I can feel stress without sudden intense pain. I can eat foods without suffering for it later. If something does cause me discomfort, it's MUCH milder pain than I get without taking these.

Tried stopping it... symptoms came back

As a test, I stopped it for 1 week, and all my symptoms were back - pain, bloating, constipation, etc. I'd advise anyone suffering to give it a go. It took several weeks of taking it before I experienced significant relief of symptoms. Although I read that for some people it works straight away. Hope this helps.

Game changer

I'm in my 70s and have a history of IBS C, OIC, and episodes of a slow stomach called Gastroparesis. There are other medical issues but I'm just mentioning gut issues here. My doctors have told me there's not much help or cure out there for IBS. It's a matter of fooling around with your diet and finding what works best for you. Well nothing seemed to be really helping until I tried Best Days. This works for me. I've been using it for over a month. I can't say I never have bad days but now my bad days are like my best days used to be. Overall I have much less discomfort and WAY less trouble with consitpation.

A bit pricey but wow!

Ok, I didn’t have high hopes despite the great reviews but I’m pleasantly surprised. I’ve always had…”issues” but with age and post-gallbladder surgery, it’s gotten so bad. As you can relate to, trigger foods hit hard with cramping and bad bathroom situations. I tried to just manage life around it but when it got to the point that I was on the floor curled up in pain and I was afraid to eat anything, I couldn’t live with it. I researched these and read research and reviews because they are expensive to try. But literally since the first day (it’s been a month), I’ve been so much better!! Normal bathroom behavior, zero cramping, no clear-the-room gas (mostly). Is it 100% these meds or am I just in a good phase? Time will tell. But it’s actually shocking how my GI tract did a 180 right after taking them. Worth a try.

HAS GIVEN ME MY LIFE AGAIN

I started taking Best Days Formula and I am not having any problems. Even foods that I use to eat that I wouldn't have dared to eat before. I take one capsule at lunch time with food (will not take a chance without food) and I am good for the rest of the day! It's that simple. If anyone has trouble swallowing capsules, here's the trick...put in mouth, take water in mouth lean head "DOWN" and swallow. It works, believe me!

It works

No more anxiety attacks or running to the bathroom due to fight or flight, cortisol throwing my gut into spasms. I’m able to go out, have fun, and not worry about IBS at all. If you are suffering from IBS that stems from or has led to anxiety, give this product a try and don’t be scared to increase the dose till you find the perfect fit for yourself, you’ll get your life back! Good luck!

Has Made a Huge Improvement

I figured my IBS was mainly triggered by anxiety. Constant diarrhea, stomach pains, the works. This stuff has been a godsend. BMs are normal, anxiety is down, and I'm sleeping great. Feeling like myself again after years of suffering. If I can help even one person with similar issues, this review is worth it.

Great product

This product has helped regulate my digestion in ways I didn't think possible. More regular bowel movements, less gas and bloating, and a noticeable decrease in abdominal pain. It's not an overnight fix, but stick with it. The results are worth it.

I have NOT had diarrhea since starting this

I have been suffering for years with the cycle of bloating and mostly diarrhea, mixed with the constipation I would have for days after having to stop myself up with Imodium. I cancelled plans, missed days of work, always had to know where bathrooms were, always drove anywhere with towels and change of clothes. I've lost friends because I would never accept invites out to lunch and shopping. Couldn't do it. I literally have tried everything OTC and RX. I saw the ad for this and thought what do I have to lose. I've taken just one capsule per day for almost a month and I feel sooooo much better. I have NOT had diarrhea since starting this. Much more regular. Not as scared to leave the house or go on long walks. I could go on and on!! Try this stuff !!!! Happy Customer
