Cultech Ltd is committed to achieving excellence in product development, manufacture and packing for the nutritional and biospeciality marketplace. Our priority is to meet all customer expectations by ensuring unbeatable standards of quality assurance, food safety and authenticity.

Lab4 by Cultech probiotic products are manufactured to the highest GMP (Good Manufacturing Practice) and food safety standards with quality control testing taking place throughout all operational processes.

Raw materials

All raw materials are examined, assessed and tested against specific quality parameters and strain identification requirements before release for use in any product.

In-process checks

Product and ingredient samples are taken at various intermediate stages of the manufacturing process to enable ongoing quality assessment and early identification of potential issues.

Packaging checks

All packaging materials are checked by hand for quality control, based on a checklist of potential risks that might compromise the safety and specification of the packed finished product.

Finished products

A comprehensive level of finished product quality testing is performed, including assessment of potential microbial and allergenic contamination, to guarantee process quality and food safety.

Environment & calibration checks

Regular environmental monitoring and calibration checks are in place for all manufacturing and production areas and all process measuring and analysis equipment.


Our cGMP (current Good Manufacturing Processes) production facilities are certified by external accreditation bodies (NSF Good Manufacturing Practice, BRCGS Global Standard for Food Safety – Grade AA+, ISO9001:2015, Kosher) for design, development and manufacture of probiotic nutraceuticals and nutritional food supplements. We are also able to manufacture probiotic products for those countries that consider them medicines.
