  • Two of the most researched strains of live bacteria
  • For human health, not yoghurt making!
  • Independent study rates our live bacteria capsules one of the best
  • One of the few products that met its label claim.

This is our top selling live bacteria product. Each capsule contains 4 billion live bacteria. We use two carefully selected strains of live bacteria, both widely used in clinical studies, Lactobacillus acidophilus La-5 and Bifidobacterium Bb-12. More importantly the species of bacteria provided by this product are specially selected for use in human health, rather than for their ability to make tasty yoghurt! Each small capsule is equivalent to 8 pots of bio-yoghurt, without all the calories!

Nature’s Best was one of the first companies to supply live bacteria capsules in the UK (over 20 years ago), so we have developed an expertise in this area. As a result of this, an independent study found our live bacteria was one of the few tested that contained the species and the strength of bacteria claimed on the label. Live bacteria capsules only work if they are kept alive in a state of ‘suspended animation’ so that after swallowing they are still viable. Nature’s Best uses sophisticated processes to ensure that these bacteria remain alive whilst in their packaging.
