What is the difference between HK L-137 and other lactic acid bacteria?
Although many strains of lactic acid bacteria and bifidobacteria are known to possess the activity to enhance immune functions, namely immunostimulating activity, the strength of the activity varies significantly among the different strains.
HK L-137 possesses an extremely higher immunostimulating activity compared to other lactic acid bacteria.
Why does HK L-137 possess such a strong immunostimulating activity?
The lactic acid bacteria L-137 expresses a much higher amount of lipoteichoic acid (LTA) outside the cell wall than do other general lactic acid bacteria, which may contribute to the strong immunostimulating activity of HK L-137.
