The Primary Benefit Is: Digestive and Immune Health Support

Digestive and immune health is supported by a diverse probiotic blend with prebiotic fructooligosaccharides to nourish gut bacteria.

This formulation uses a time-release capsule to help maximise viability through the digestive tract, with a focus on maintaining a balanced gut microbiome.

How Does This Support Digestive and Immune Health?

Probiotics help keep a balanced gut microbiome and are involved in supporting normal digestive function and immune system activity, with evidence suggesting benefits for gut comfort and microbial balance. The prebiotic Fructooligosaccharides provide fuel for beneficial bacteria, supporting their activity.

Dr. Ouwehand of Wageningen University found that high-CFU multi-strain probiotic blends can support digestive comfort and immune function, in line with EFSA-inspired understanding of probiotic action.
