JCM5805（プラズマ乳酸菌）). This strain has immunostimulatory activity and as there is not a claim category for that, the ads have to carefully keep from making a specific claim. When you navigate over to the R&D section it gives research results, but only uses the strain name and not any product names.
Among the products containing this probiotic are a yogurt drink, a water drink, a fermented lactic acid drink and a fortified drink which also contains DHA and Vitamin C.
