The Active Ingredient Is: Saccharomyces boulardii (probiotic yeast)

Saccharomyces boulardii is a probiotic yeast that helps maintain normal gut function by helping maintain intestinal barrier integrity and by interacting with the gut immune system.

This shelf-stable probiotic is suitable for vegetarians and vegans, and the capsule shell is vegan-friendly hydroxypropyl methylcellulose and no other actives listed.

What Does Saccharomyces boulardii Do?

Saccharomyces boulardii helps support gut health by reinforcing the intestinal barrier, inhibiting harmful microbes, and modulating immune responses in the gut mucosa. It can outcompete unwanted bacteria and helps balance your native gut flora.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.

Nutri Advanced was chosen as our partner for Saccharomyces Boulardii because this well recognised UK practitioner brand brings a focused specialty in gut health and immunity through clinically relevant probiotic science. The product features Saccharomyces boulardii as the sole active ingredient, delivered in a shelf-stable, vegan capsule, aligning with Welzo’s commitment to transparent sourcing and suitable formats for diverse lifestyles. This alignment with our standards is reinforced by the brand’s established reputation within the UK wellness community, supporting trust and long-term consistency in supply.

We picked Nutri Advanced over other options because the yeast-based probiotic used is described as a safe, non-pathogenic strain that can be used alongside antibiotics, with potential benefits for gut barrier integrity and microbial balance as indicated in the research into the product. Our collaboration is guided by our expert team of doctors, nurses, and nutritionists, who evaluate product integrity, and by how we verify ingredient quality to ensure ongoing safety and transparency.

The partnership is anchored in Welzo’s brand evaluation process, combining brand credibility, product suitability, and rigorous vetting to deliver a reliable probiotic option for gut support.
