I trust you saw my previous note (in this review process) that the interaction between the Meraki Methylene Blue and several prescriptions and supplements that I take can be potentially FATAL -- and not just in a cumulative process. It can cause lethal levels of high blood pressure when combined with some seemingly innocuous supplements. I really like being in charge of my own herbal supplementation but when there are real dangers out there like this, I (almost) wish for some regulatory control!
