Do you think your experiencing die off or just experiencing the side effects of the preservative/chemicals in the GSE. Is there really anything in GSE that would cause cell membrane leakage(Die-off). Sounds like GSE acts as a inhibitor rather than causing cell membrane leakage. Its possible You might being experiencing an inflammation response from some of the chemicals in GSE?
Its interesting how much more bitter the drops are than the tablets. I could easily chew up one tablet without gagging. 10- 12 drops would be so bitter I could not tolerate it. So it raises a question of their processing methods. I've tested out some pomegranate extracts where some capsules actually tasted and looked like pomegranate and others tasted and looked like processed dirt. Some comapanies process the hell out of their herbs that you don't taste much of the active ingredients. Another example is echinacea: I've tasted some echinacea that will make your tongue num. Others tasted highly processed. Its interesting how certain active ingredients of herbs can have unique taste or sensation of the tongue.
Anyways, I hope GSE helps. Keep us posted with your long term results.
