Lab4 by Cultech offers a full range of products and services to existing and potential customers, from bulk powders, to contract manufacturing to individual product manufacture as private label or our own ProVen Probiotics brand. We are also excited to announce our brand new in-house fermentation plant specifically designed for our Lab4 strains – high quality probiotic strains, harvested and freeze-dried in our proprietary controlled environment to ensure purity, stability and viability.

Lab4 by Cultech has enhanced its manufacturing capability with new in-house fermentation plant specifically designed for the LAB4 strains. This in-house facility ensures production of high quality probiotic strains, harvested and freeze-dried in a controlled environment whilst ensuring purity, stability and viability.

We work with companies who are either looking to sell our ProVen Probiotics brand in their own domestic market or to take the Lab4 probiotics as part of their own label range. We offer a wide range of formulations and can adapt any of the ProVen Probiotics range to suit your market or can develop new formulations specifically for you. The wide range of formulations means that we have products that are suitable for both health care practitioners (including doctors, nutritional therapists and other health professionals) and the general public.
