- Development of new safety evaluation systems
Commitment to Safety in Product Development
We place the highest priority on safety, for not just the final product, but throughout all research and development processes. The depth, strictness, and quality of our safety evaluations ensure products not only comply with the specifications determined by the government, but that they also meet the high standards set by Yakult.
In addition, for our probiotic products we conduct safety studies down to the strain level and are acquiring data to verify the safety and reliability of our food products. The Safety Research Department ensures reliability through objective safety evaluations as an independent organization established within the Yakult Central Institute.


Safety Research that Puts Customers First
- Pursuing the Safety of Products that have Gone to Market -
The Safety Research Department also conducts studies to support our products after they become available in the market. For example, it conducts studies to assess the influence of food ingredients developed by our company on the effects of pharmaceuticals (drug/food interaction). The Safety Research Department will continue pursuing the safety of food in the market as an important research agenda, taking into consideration purposes of use.
Development of New Safety Evaluation Methods
In the Safety Research Department, researchers in different fields maintain and manage advanced equipment and facilities and conduct highly accurate safety evaluations. They are also making efforts to develop and incorporate new safety evaluation methods. By using the new methods, we aim to enhance the rigor of our safety evaluations.
