Guaranteed Safety

PS128 does not require FDA approval (since it is not designated as a food additive.) To certify its safety, self-affirmed GRAS (generally recognized as safe) status was obtained. Before being granted this designation, qualified experts must agree that scientific data and information about the substance establishes the safety of its intended use. Lactobacillus plantarum PS128 received self-affirmed GRAS status in 2020.

實驗工作

The strain PS128 was identified as Lactobacillus plantarum [1]. L. plantarum is generally recognized as safe for consumption by major regulatory bodies.

PS128 is not genotoxic nor resistant to antibiotics [2]. It meets EFSA food safety standards.

In both human and animal trials, PS128 has not demonstrated any side effects [3][4].
