Can tonkat ali raise psa levels?

Because this supplement has been used for impaired libido and sex life and it is expected to boost testosterone level so its effect on the prostate is a possibility although we do not have any concrete data. To rule out this adverse effect, you should stop this supplement for at least a month before having a PSA retested. Good luck to you.

There is no published sudy of its affect on PSA. So we dont know.
