The Active Ingredient Is: Bifidobacterium Longum (BL-05)

Bifidobacterium Longum is a probiotic bacterium that forms part of the gut microbiota and can contribute to gut health as a component of a balanced microbiome.

This product uses the BL-05 strain of Bifidobacterium Longum, a non-GMO form commonly used to support digestive balance and nutrient absorption in the context of a probiotic supplement.

What Does Bifidobacterium Longum Do?

Bifidobacterium Longum is known for supporting a balanced microbiome and may contribute to immune function and inflammatory balance within the gut environment, with potential effects on nutrient absorption and digestive regulation.

In the broader nutritional context, these actions align with gut health maintenance and normal digestive function, as described in established dietary guidance and EFSA/NHS understanding of probiotics and gut microbiota.

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

(We selected Custom Probiotics as our collaborator for B.

This focus on purity and accessibility resonates with Welzo’s ethos of transparent, evidence‑backed supplementation. Custom Probiotics is recognised for producing probiotic products that are dairy‑free, sugar‑free, gluten‑free and non‑GMO, matching many consumer needs and regulatory expectations.

(The maker’s focus on quality is supported by third‑party validation practices, with their products described as allergen‑ and GMO‑free, reflecting a rigorous compliance mindset.) This aligns with our own benchmarks for product safety and purity, which you can explore in our our rigorous testing protocols and explained by our expert team of doctors, nurses, and nutritionists.
