What a difference.

"Since being on this my IBS symptoms are pretty much not there. I used to be in horrific pain all day everyday and would even feel hot, dizzy and in so much pain that I would actually faint off the toilet. I didn't want to leave the house and IBS literally took over my life. I never write any reviews like this but if I can help even just one IBS sufferer then it's worth it. For the first week I did get the side effects (gas mostly) but after that I felt absolutely fine again. Please try this, I didn't think it would work but it did and I have honestly never been happier!"

This has helped me live a near normal life

"I have been taking 1 pill every night for over six months and this has helped me live a near normal life. It took a couple weeks for me to really feel the difference. I continue to have flare ups now and again but can up to 2 pills for 1 night and am back to normal the next day. I have found that regular exercise is also very helpful. I am 56 and just completed a 1/2 marathon, that would have been impossible before I started taking Best Days formula. Still have to watch what I eat to some degree, but nothing like before. "

It was just spot on!


"I had stomach problem since 2009. I am not going into detail cause no one is interested in my entire experience with IBS. I should say that due to IBS I had to quit university, part time job and worse of all the man I have been with since many years left me. So I went from being one of the most social people to being one of the most lonely people. One day I heard of something called “Best Days Formula” I don't need to explain how it effected not only on my stomach but it has brought a great change in my life as a whole, it was just spot on!"

Tired of gut supplements that

don’t make a dent?

Mountains of Research Now Reveal Why Most Are A Waste Of Money!

Did you know that taking a probiotic is like throwing a pebble into a vault of acid?


That’s because not only do 96% of them fail to make it past your stomach acids…


But most contain weak, low-grade formulas that fail to catch the true culprit behind IBS:


A weak Gut-Brain Connection that derails your entire digestive tract.

Dozens of scientific papers now confirm...

A “Gut-Brain Disconnect” Impairs Crucial Processes Like:

Breaking down food so that it doesn’t sit in your stomach

Moving food through your intestines at a normal pace (resulting in regular bathroom visits)

Maintaining a strong gut lining (preventing bad bacteria from seeping into your bloodstream)

Fighting off mental illness and long-term disease

And much more

99% Of Supplements

Miss This!

Most solutions completely ignore the crucial nerve that lets your Gut and Brain communicate - the Vagus Nerve.

"Until now, it wasn't clear what ingredients were needed to support a healthy Vagus Nerve and Gut-Brain connection. But that's changing!"

- Dr. Green | Law of Nature

The Vagus Nerve is like a highway across your body, sending signals that regulate

Digestion

Gastrointestinal Motility

Digestive Enzyme Secretion

Nutrient Delivery

Microbial Balance

Immune Function

And More

Important neurotransmitters like dopamine, serotonin, and norepinephrine travel along your Vagus Nerve…

But just like a bad cable or weak connection, your Vagus Nerve

can fail to send the right signals…

Cutting off these crucial bodily functions!

But most supplements (such as probiotics) ignore this entirely - leading to results that often disappoint.

Over time, this disruption can lead to..

A Gut-Brain Blackout that makes pain-free digestion impossible

The bad news is a compromised Gut-Brain Connection can often weaken over time


Leading to severe, debilitating, and long-lasting symptoms like:

Unpredictable flare-ups that leave you racing to the bathroom

Low tolerance for most foods (even foods that used to feel “safe”)

Embarrassing bloating, gas and gurgles that make social outings stressful

Never knowing when a troubled gut will take over your day

Rippling cramps that strike suddenly and last for hours

Urgent bathroom visits that make it hard to function normally

Which makes “just dealing with itnot an option if you want to get your life back from IBS and live better, symptom-free days.

That’s Why I Created

Best Days Formula

The only science-backed formula that repairs a “Gut-Brain Disconnect"

Ready to get your life back from your troubled gut?

Our secret?

A unique blend of 15 exotic ingredients

3rd-Party Checked for Safety & Efficacy 

  • Our Proprietary Soil-Based Probiotic Powerblend

    SEBclausii™, SEBtilis™, SEBiotic™

    These spore-forming strains have been clinically proven to be 10x to 100x more effective than generic or lactic-based strains with 250x higher survival rates than regular probiotics. This revolutionary, shelf-stable blend is designed for maximum strength and survivability without the fillers and binders that could irritate your gut.

  • The Garden Fertilizer for Your Gut

    Inulin Root

    Picture Inulin Root as the ultimate gut garden fertilizer, nourishing your good bacteria so they flourish like vibrant, healthy plants. This helps keep the peace in your belly, taming gas, bloating, and discomfort, while fostering clear, harmonious chats between your gut and brain. This is your secret ingredient for a blooming, happy gut garden!

  • The Electricity That Powers Your Vagus Nerve And Body

    Zinc

    A key deficiency in those with IBS, Zinc binds between your cell receptors and helps your neurons send the electric signals they need to. Failing to get enough is like cutting off power to your body’s entire electrical grid - leading to digestive miscommunication and chaos.

  • A Digestive Lubricant That Soothes Your Gut Lining

    Licorice Root Extract

    The human gut is lined with 100 million nerve cells - but a weak or damaged gut lining can upset your gut’s sensitive nerves. Licorice Root Extract has been shown to act as a soothing balm that coats and calms your upset gut. Just like oil keeps an engine running smoothly, this ancient digestive aid acts as a lubricant, nurturing your gut's lining, and helping it sing in perfect harmony with your brain.

  • A Crucial Fuel Source For Immune and Intestinal Cells

    L-Glutamine

    L-Glutamine serves as a conduit, enhancing communication between your gut and brain. It gives your gut’s cells the energy they need to ensure clear signals are sent and received, leading to better coordination and improved overall gut health.

  • A Soothing Balm For Your Digestive System

    Aloe Vera Leaf

    Aloe Vera soothes your digestive system as it glides through your gut in order to soothe inflammation and irritation. It provides a gentle, calming effect on the digestive tract that allows your gut to relax and function the way it’s supposed to.

  • Supercharged Cellular Repair For Your Gut Lining

    Vitamin C

    Vitamin C works like a construction crew on overdrive, helping to repair and rebuild the lining of the gut. This aids in sealing any leaks, reducing inflammation, and improving the overall health of your digestive tract.

Great if you have IBS

Reviewed in the United States 4 hours ago.

Verified Review

My IBS-D was mainly triggered by anxiety but sometimes food also. After trialing SSRI’s and having no luck, I did some online research and learned about the Neurogut signaling. I asked my doctor if I could trial best days formula so I did. At first I noticed the deep sleep but also the lack of that “spaced out” feeling you get with the antidepressants, I actually just felt like myself. After about 3 months on it, I slowly week by week increased the dose to 2 capsules a day and that was my perfect fit, 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 a try, you’ll get your life back!! Good luck!!

I still have yet to receive a solid diagnosis on why I am nauseated 24/7 but in the meantime this has been a gamechanger. I went from puking daily, visiting the hospital every other week to eating literally anything I wanted. I have tried tecta, PPI's, probiotics, elimination diets, everything you can imagine. I can even drink coffee in the morning now!!! Literally changed my life, overnight. I now can work, without worrying about sick days. Please, please, take a chance with this.

After suffering for many years with IBS and trying almost everything from cholestipol to Fodmap I was feeling hopeless. As I got older it was worse. But within six weeks of taking it my IBS got 80% better. I feel like my life has been given back to me. I have some minor side effects but think for me it’s a miracle. I am so happy now.

Sadly didn't work, but got money back!

Reviewed in the United States 1 day ago.

Verified Review

Unfortunately, this did NOT work for me, so I called up the company selling this product and they GAVE returned my money AND gave me another 20 percent of my purchase BACK! I didn't even have to send my bottle back and they didn't even bother to ask any questions, so I love when a company honors its guarantee. My IBS started recently, and I'm still learning more about my food triggers and hope to solve it soon. Hope it's nothing serious.

Excellent (very minor side effect)

Reviewed in the United States 1 day ago.

Verified Review

“I’ve suffered from constipation on and off for over 20 years. No one could figure it out. I didn't eat while at school because I was afraid of the results. Some telling me it "was all in my head". Others saying it was a result of my diet. I switched my diet, I meditated, I did everything I could but no joy. Finally I met a doctor who understood exactly what I was going through. He put me on a regimen of Best days formula. What a difference. I can honestly say my life has completely changed."
