Do a search on this forum and see what you come up with.
Hello q hope you are having a great weekend,
I did a search on the forum regarding the Qing dai after your response and saw some forum members had success and no effects for some others, kind of mixed responses. But I didn't see anyone had a longer positive effect for an extended period from Qing dai.
Evinature founders and scientific advisors created an interest in the products to give a try. 2 out of 3 founders are directly associated with the Integrative Gastroenterology unit at Sheba Medical Center Israel and both the scientific advisors are US-trained MD and RD respectively and both are located in the US.
I am not recommending or suggesting anyone on this forum try these based on my posts. I will keep posting to share my experiences in the next coming few weeks.
