Efficacy of HELICOLESS

1. It helps stomach health by stomach protection

HELICOLESS shows the efficacy to protect the stomach from ulcer inducing factors. It is implicated that this efficacy may be due to its high antioxidant values (ORAC Value) and its anti-inflammatory action (it inhibits the generations of Prostaglandin, Thromboxane, and Leukotriene).

HELICOLESS exerts anti-H. pylori activity, which may result from its inhibitory activities on protein synthesis
(inhibiting methionine incorporation) and on DNA synthesis (inhibiting DNA gyrase and dihydrofolate reductase).
