A Breakthrough in IBS Treatment

According to a large-scale study, 80% of women have IBS because of "distorted signals" between the brain and gut.


Best Days Formula is designed to restore the connection between your brain and gut.


Think of these powerful ingredients as little repairmen. They repair all the cables between your gut and your brain, which lets your brain set things right.


Once your brain can send clear signals to your gut again, the problems in your gut will slowly start to fade away. You’ll feel less bloated, you’ll have fewer cramps, and your bathroom schedule will look more normal.


After a few weeks, you’ll be nearly pain-free. And after a few months, you’ll forget what it’s like to have IBS.


Because the science behind this is so new, Best Days is the only formula on the market designed to repair your gut-brain connection.


Women everywhere are giving their IBS symptoms the boot with this new IBS remedy – and trust us, you don't want to miss out! 50K+ already experiencing relief means this stuff is as good (or better!) than it sounds.

     Great if you have IBS

Reviewed in the United States on April 20, 2023

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.

After years of suffering from IBS-D, trying multiple prescriptions, diets, over the counter meds, etc., Found Best Days online and I saw personal accounts from other IBS-D sufferers, I decided to give it a shot. Continued doing research and came across posts about soil-based probiotics. Sounded promising, the benefits were very appealing. I've also been dealing with intermittent sleep anxiety and insomnia. BMs were improving, anxiety and stress levels were way down, sleeping great. Started to feel like my old self again. Been taking it since Nov 2021 and have had 0 negative side effects. Highly recommend this to those suffering from IBS-D.

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! 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 on April 18, 2023

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!

      My experience so far

Reviewed in the United States on April 17, 2023

Verified Purchase

Irritable Bowel Syndrome sufferer for years. This is working really well for me. There are still certain foods I avoid and I very occasionally get a flare up (normally because I have either over eaten or eaten something I would normally avoid). I take 2 capsules at night time, I did try to reduce this down to just one but after a couple of weeks all my symptoms were back, pain, bloating, constipation, etc. I'd advice anyone suffering to give it a go. It took several weeks of taking it before I experienced significant relief of symptom. Although I read that for some people it works straight away. Hope this helps.

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. Still have to watch what I eat to some degree, but nothing like before.

MAIN INGREDIENTS


SEBiotic™

SEBiotic™ helps promote healthy digestion by targeting the gut-brain signaling pathway. It also inhibits the growth of harmful bacteria such as Clostridium difficile, which can cause inflammation and infection in the gut.

SEBtilis™

SEBtilis™ contains a strain of Bacillus subtilis, a beneficial bacteria that can help modulate the immune response and improve gut barrier function. Regular supplementation with SEBtilis™ may help prevent infections and reduce inflammation in the gut.

SEBclausii™

SEBclaussi™ can help support the immune system and improve gut health. It contains a strain of Bacillus clausii, a beneficial bacteria that can help boost the body's natural defenses against infections and restore the balance of healthy bacteria in the gut.

Inulin (Prebiotic)

Inulin is an amazing source of PREbiotics. It's a fiber that resists digestion in the small intestine and reaches the colon intact, where it serves as food for beneficial bacteria.

MOST ASKED QUESTIONS


When can I experience results from BEST DAYS?

Everyone’s body is unique so individual results may vary. While some customers started seeing results in as early as 2 weeks, it typically takes up to 6 to 8 weeks for the probiotics to fully colonize the gut.

This is why we recommend trying BEST DAYS for 8 weeks in order to enjoy the benefits.

Does BEST DAYS have any side effects?

BEST DAYS is not known to have any major side effects.

BEST DAYS is made using high quality, natural ingredients and has been tested safe for consumption. It was formulated to be stimulant-free, which makes it ideal for long-term consumption.

Because of its high potency, some customers may occasionally experience mild bloating at the start. This is normal and usually goes away after a few days as your body is adjusting.

But if you experience adverse effects, please stop consumption and consult a doctor. If you are on medication or suffer from health conditions, we recommend informing your doctor your interest in consuming our supplements.

In general, you should follow the recommended dosage of 2 capsules a day.

Can I take it if I have SIBO?

You may have read internet advice that suggests you should never take probiotics if you have small intestinal bacterial overgrowth (SIBO). Since the condition is caused by an excess of bacteria (including beneficial bacteria) in the small intestine, why would you add more?


However, if you follow that advice, you’d be missing out on a research-backed, effective treatment.


A lot of people with SIBO have had found relief with the right strains of probiotics.


Even though it may seem counter-intuitive, research CLEARLY shows that probiotics can be very effective for treating SIBO, improving both symptoms and lab values.


1. One SIBO-probiotics study found probiotics to be more effective than Metronidazole, an antibiotic treatment for SIBO.

2. Other Study. 

Does BEST DAYS contain gluten, soy, peanuts, dairy, shellfish or any other allergens?

We are undergoing lab testing as of now. Please message us here: contact@lawofnature.com so we can remind you with the results. 

Is it safe to take if I'm pregnant/breastfeeding?

Please consult your doctor first before taking BEST DAYS as he/she would be more familiar with your health condition. That said, BEST DAYS is generally safe to consume when you are breastfeeding/pregnant.

Will BEST DAYS work for me if I'm not dieting or working out?

Yes, many of our customers have noticed improvements without changing their diets or starting fitness.

BEST DAYS contains soil-based probiotic strains that have shown in clinical studies to improve patients’ weight management, with no changes to their lifestyle and eating habits.

However, that does not mean that it’s possible to eat 5,000 calories a day and still see significant results in a short period of time. It is not a magic pill.

If it doesn't work for you, simply send us an e-mail and we'll refund every penny and pay you 20% on top for your time.
