My bp runs on the low side. Stevia causes me, and most people I personally know, adrenal pain and low cortisol symptoms, contrary to their study.
Maybe, as I mentioned, it depends on whether you use the whole plant or extract.
I agree bp raising effects for us is a good thing, but stevia or the extract may be behind some of the problems some people are having with these supplements.
Years ago I read Stevia lowers cortisol, which certainly matches up with the experiences of myself and loved ones. However, this study contradicts that.
Regardless of contradictory information, we all react differently and maybe this will help someone reacting to the product.
