In probiotics, there are 3 concepts to distinguish: the genus (e.g. Bifidobacterium), species (e.g. Bifidum) and strain (e.g. Rosell-71). You can recognise strains through numbers, letters, or names.

Each bacterial species and strain has specific and different health benefits. Bifidobacterium Bifidum, for example, is not the same as Bifidobacterium Longum, and within each species there can be thousands of different strains.

As proven benefits are connected to specific bacterial strains, it's important to identify strains when choosing a probiotic. Not just to verify that the included strains will actually have an impact (it’s worth checking whether they’re evidenced by clinical trials), but also to see if they'll deliver the benefit you're after.

The Smart Probiotic contains 7 clinically studied strains, of which include proprietary strains, supporting gut, brain and immune health in one daily capsule.
