This formula combines multiple clinically studied probiotic strains, a beneficial yeast (Saccharomyces boulardii), prebiotics, gut-soothing compounds, and essential vitamins and minerals in one product. Unlike standard probiotics that only deliver bacteria, this product is designed to support the gut microbiome, digestion, immune function, and nutrient absorption at the same time.

These vitamins are included because gut health and nutrient status are closely connected. A healthy digestive system supports nutrient absorption, and several of these vitamins also play direct roles in gut and immune function.

  • Vitamin D3 helps support immune activity in the gut lining and plays a role in maintaining the intestinal barrier
  • Vitamin K2 works alongside gut bacteria and supports normal metabolic processes
  • Vitamin B12, folate (5-MTHF), and B6 support cellular energy production and nervous system function, which can be affected when digestion or absorption is compromised

Using active, bioavailable forms helps ensure these nutrients are more readily absorbed, especially for individuals with digestive sensitivity.

Together, these vitamins support the gut–immune connection, making the formula more comprehensive than a probiotic alone.

These ingredients provide additional digestive and gut lining support:

  • N-Acetyl-L-Cysteine (NAC) supports antioxidant activity and gut barrier health
  • Mastic gum has traditionally been used to support stomach and upper GI health
  • Magnesium glycinate supports regularity and muscle relaxation in the digestive tract

Together, they help support a healthy and comfortable digestive system beyond probiotics alone.


Saccharomyces boulardii is a beneficial yeast that helps support gut balance, especially during times of digestive stress, travel, or antibiotic use. Unlike bacterial probiotics, it is not affected by antibiotics and can help maintain healthy gut flora while supporting regularity and digestive comfort.

This is one of those things you don’t realize is helping until you stop taking it. Ran out for a few days and everything felt off. Back on it now and better again.

David R.
★★★★★

I get bloated super easily and this toned it down a lot. Not gone completely but way better than before. Didn’t change anything else so I’m pretty sure it’s this.

★★★★★

I’m about halfway through the bottle. Digestion feels more predictable (which is nice). No bad taste, no upset stomach. I take it with breakfast and forget about it.

Jason R.
★★★★★

Only been taking this for about 2 weeks but my stomach feels calmer. Hard to explain, just less… weird? No side effects so far which is a win. Bottle is smaller than I expected but you don’t need much.

I've tried a lot of probiotics but this one feels different. My stomach finally feels normal again.

★★★★★

Gentle, effective, and easy to take. I noticed a difference within days.

This feels like a full gut system, not just a probiotic. Worth every penny.
