Homeopath doctor prescribed.. i’ve been on it a few months and I don’t notice a difference. That being said I have always awakened with lots of energy and I have an incredible immune system. I’m not sure that I would notice the difference but he is most convinced that it is very very good for me to take this. It works at a cellular level and I trust my homeopath Dr he has taken good care of me for the better part of 15 years.
This is an excellent product at a great price.
