Is it true that Kratom consumption lowers resting heart rate in human users?
Unclear. The only relevant evidence comes from a preliminary study of long-term kratom chewers showing parasympathetic dominance on heart-rate-variability indices, and a review reporting that kratom users had higher odds of sinus tachycardia than controls. Neither directly measures resting heart rate in kratom users, so the claim is not settled.
