SMART STRAINS is a science-led probiotic brand bringing clinically-proven, strain-specific live bacteria to the everyday. Backed by 500+ human studies and 40 years of microbiome research — formulated by Dr. Megan Rossi, PhD — each product is designed around a simple belief: not all probiotics are created equal.
The right strain, at the right time, in the right way.
From daily gut and immune support to targeted formulas for antibiotic use, fussy little ones, and vaginal microbiome health, SMART STRAINS replaces the one-size-fits-all approach with precision — clean-label, rigorously tested, and built on real clinical evidence.
