Quality Products

Research on probiotics continues to show that different strains (types) have different beneficial effects on the body. At OptiBac Probiotics we recognise this, and use well researched strains that have been scientifically tested for their specific health benefits. This way, our range of 11 probiotic supplements is sure to offer you a tailored supplement that you can trust.

At OptiBac Probiotics we only use well-researched strains of the highest quality. You can find out more about strains here, or read about our clinical trials - which are second to none on the UK market.

As well as clinical trials, all of our probiotic strains undergo rigorous tests to ensure their ability to survive at room temperature, and to survive stomach acidity.

We promise you:

  • No need to refrigerate
  • No artificial sweeteners or flavourings
  • Significant clinical research & documentation on our strains
  • Survival through stomach acidity
  • Number of live probiotics guaranteed until expiry.
