Key Features

  • Vegan, dairy-free, gluten-free, and non-GMO

  • 11 billion CFU per serving

  • No refrigeration required

Spore-based probiotics are derived from soil and are often referred to as soil-based organisms (SBOs). Traditionally, people consumed these beneficial microbes naturally through unprocessed foods grown in healthy soil. Modern agricultural practices, such as over-processing and heavy pesticide use, have reduced our natural exposure to these organisms, making supplementation more important than ever.

Advanced Probiotic + Prebiotic Synergy

Three fully sequenced, registered spore-based probiotics work together with VitaFiber prebiotic to promote a balanced microbiome and support overall digestive health.*

Genomically Researched Strains

Each spore-forming strain is identified and registered for its specific function:

  • Bacillus coagulans (SNZ1969)

  • Lactospore Bacillus coagulans (MTCC 5856)

  • Bacillus subtilis (DE111)

11 Billion CFU Per Serving

Take 2 capsules daily, or as directed by your healthcare professional.

No Refrigeration Needed

Because CoreBiotic contains only spore-forming strains, it' naturally heat-stable and resistant to stomach acid, ensuring that live probiotics reach the intestines where they provide optimal benefit.*

Non-GMO, Vegan Formula

Manufactured without milk, eggs, fish, shellfish, peanuts, wheat, soy, or gluten. Produced in a facility that may process other ingredients containing these allergens.
For those avoiding prebiotics or fiber, Researched Nutritionals also offers CoreBiotic Sensitive.

Benefits of Spore-Based Probiotics

Spore-forming strains have key advantages over traditional live probiotics. Their protective outer shell allows them to survive harsh stomach conditions and reach the intestines intactno refrigeration required.

Clinical studies, including double-blind, randomized, placebo-controlled trials, have confirmed the safety and efficacy of SBOs in humans. Once in the intestines, these spores germinate and behave like other probioticssupporting beneficial bacteria growth, crowding out harmful species, and promoting gut balance.

Each strain in CoreBiotic is genomically verified for strain specificity, ensuring accuracy, potency, and safety in every batch.

Very comfortable Slippers. Great buy!
Size: 12-13 Women/10.5-11.5 Men, Color: Charcoal
I bought these to replace a pair of slippers that I have had for years that are very similar to the slippers I bought, but I had worn a hole in the leather on mine, so I had to find something new and similar. These slippers are worth the money they are very comfortable, and I am sure they will last for years. They are a little tight around the ankle cuff but they are still new and I am sure they will wear in a little more when I start wearing them more.

Great slippers but disappointing quality.
Size: 7.5-8.5 Women/6-7 Men, Color: Ash, Size: 7.5-8.5 Women/6-7 Men, Color: Ash
Extremely comfortable, attractive slippers but the stitching came loose on both leather trim areas almost immediately. I tried to sew/glue down the stitching (as seen in photo) but it kept unraveling. Disappointing as these slippers are great in every other way (though they do run a bit big...I wear a 9 but ended up with a 7.5-8.5 which fits with a bit of room to spare even with thick socks). I just hope they hold up after my latest attempt to stop the thread from pulling out any more as I do really love wearing them. Perhaps I just got a bum pair?

Quality and comfort
Size: 10.5-11.5 Women/9-10 Men, Color: Black
Comfortable and fit well. I got these to replace a very old pair that finally wore out! Warmth is medium (I wear puffer booties for when it's really cold). Quality on these is great!

Can't go wrong with Acorn for as long as they last!
Size: 12-13 Women/10.5-11.5 Men, Color: Charcoal
Acorn is just a great company all around. I had bought my husband these slippers over 20 years ago. They are still in great shape although the sole has worn in some places. But nothing's coming apart! However, I decided to replace them for him. His foot is 10.5 and they are a little hard to get on right away-of course, after over 20 years of having "worn in" the original pair, anything would feel tight. So I'm not holding this against them. They will relax with use. The only difference is that the original sole was black and these are tan. I think I would prefer the black, but since it's only being worn in the house, no big deal. My husband has really cold feet and these slippers never fail to warm his feet right up! He said they feel really soft to walk in and like the cushioning. They're not too heavy and fit him great! I have Acorn slippers myself that I've worn every single day in the house and outside to the mailbox too. They last.
