BioGaia Gastrus PURE ACTION combines over three decades of microbiome research with a growing interest in Lactobacillus reuteri — the same probiotic species that’s gained attention among clinicians and health enthusiasts following Dr William Walsh’s widely discussed L. reuteri yogurt experiments.
This practitioner-grade, vegan-friendly probiotic features two human-derived strains — L. reuteri DSM 17938 and L. reuteri ATCC PTA 6475 — clinically studied for their ability to:
-
Support healthy gut flora balance and digestive comfort
-
Maintain a resilient intestinal barrier
-
Promote normal bowel regularity
-
Help modulate inflammation within the gut environment
Formulated for sensitive digestive systems, Gastrus PURE ACTION delivers a precise, research-based daily dose of 200 million CFU across both strains. Each capsule is FODMAP-friendly, vegan, and free from gluten, dairy, and artificial additives.
This product is practitioner-grade, designed for those seeking targeted, evidence-based probiotic support rather than general multi-strain blends.
At Fairfield Nutrition, we choose to stock only products used in clinical settings and supported by robust research, and BioGaia Gastrus is a standout example of this.
