The Core Ingredient Is: Probiotic Bacteria (Lactobacillus and Bifidobacterium Strains)

Probiotic bacteria are living microorganisms that support a healthy gut microbiota balance. This multi-strain blend aims for broad gut support using Lactobacillus and Bifidobacterium species in a vegetarian capsule form designed to protect viability, and stay effective.

This formulation highlights a diverse probiotic profile with substantial CFU potential to help maintain normal gut function and microbiome balance, alongside other ingredients that support probiotic stability and delivery.

What Does Probiotic Bacteria Do?

Probiotic bacteria play a part in supporting gut microbiome balance and digestive comfort, and may contribute to immune resilience as part of a balanced diet. Evidence from clinical research supports multi-strain approaches for gut health and wellbeing.

Dr. Sanders of University College London found that multi-strain probiotic interventions can improve gut bacteria balance and digestive comfort.
