Leading research fellow at King’s College London Dr Megan Rossi—also known as The Gut Health Doctor—created Smart Strains, a new line of live bacteria probiotic supplements to target specific strains at specific doses. In this targeted range of probiotics, consumers will find support For When You’re on Antibiotics, For Fussy Babies, For Your Immune System, and For Your Vaginal Microbiome.

While Smart Strains’ solution for those on antibiotics is formulated with 10 billion live Lactobacillus rhamnosus, (or LGG) the most documented bacterial strain, Smart Strains for your immune system features not only LGG but also BB-12, the world’s most published Bifidobacterium strain, to deliver clinically proven support for the upper respiratory tract during the long, cold, and dry months of winter.
