Review: Klaire Labs Ther-biotic Complete – what’s in it?

This probiotic offers 12 species of probiotic bacteria delivered with a special brand-specific method of protecting some of the more delicate probiotic strains so they can enter the alkaline intestine intact. This is a nice touch. There is a USA version and a Canadian version. We explain the differences below. Strains bolded are commonly found in the human vaginal tract.

ProThera KlaireLabs

USA – 60 x 280mg vegetarian capsules containing:

  • Lactobacillus rhamnosus (6.0+ bn CFUs)
  • Bifidobacterium bifidum (5.0+ bn CFUs)
  • Lactobacillus acidophilus (3.0+ bn CFUs)
  •  Lactobacillus casei (2.5+ bn CFUs)
  • Lactobacillus plantarum (2.0+ bn CFUs)
  • Lactobacillus salivarius (2.0+ bn CFUs)*
  •  Bifidobacterium longum (1.0+ bn CFUs)
  • Streptococcus thermophilus (1.0+ CFUs)*
  • Lactobacillus bulgaricus (1.0+ bn CFUs)* (Lactobacillus delbrueckii subsp.)
  • Lactobacillus paracasei (0.5+ bn CFUs)
  • Bifidobacterium lactis (0.5+ bn CFUs)
  • Bifidobacterium breve (0.5+ bn CFUs)

Other ingredients include inulin derived from chicory (so anyone on a low-FODMAP diet may have an issue). The capsule is made from hydroxypropyl methylcellulose and water, and InTactic, the proprietary acid protector is made from polysaccharide complex and L-leucine.

*Canada – Canadian law requires different labelling, however the ingredients are the same. Streptococcus salivarius subsp. Thermophilus, Lactobacillus delbrueckii subsp. Bulgaricus, Inulin, polysaccharide complex, hypromellose, water, and L-Leucine are not considered to be medicinal ingredients. The measurements for calculating how many bacteria are in each capsule also differs, but equates to the same thing.

Canadian product bacteria count details

  • Lactobacillus rhamnosus (6 X 109 CFUs)
  • Bifidobacterium bifidum (5 X 109 CFUs)
  • Lactobacillus acidophilus (3 X 109 CFUs)
  • Lactobacillus casei (2.5 X 109 CFUs)
  • Lactobacillus plantarum (2.0 X 109 CFUs)
  • Lactobacillus salivarius (2.0 X 109 CFUs)
  • Bifidobacterium longum (1.0 X 109 CFUs)
  • Lactobacillus paracasei (5.0 X 108 CFUs)

Typical microflora found in the vagina of healthy women

  • Lactobacillus crispatus
  • Lactobacillus jensenii
  • Lactobacillus gasseri
  • Lactobacillus iners
  • Lactobacillus vaginalis
  • Lactobacillus rhamnosus
  • Lactobacillus acidophilus

So how useful is this probiotic for treating the vagina?

We think it’s a good all-rounder (which is what it’s designed to be) for the gut, but it lacks most of the probiotic strains commonly found in the vaginal tract of healthy women, and therefore it may not be the best choice. Speak to your healthcare provider about it – they may have further insights.
