I work with all that kind of stuff and i can say that it can help you a lot if..... if your body need that. I always check what the body needs and doing the right colloidal you can improve a lot.
Every person has a different needs and you must do what is need for you and what your body needs. It can be silver (ag), gold (au), cupper (cu), sn or others.
You should check someone that work with this things to advise you in order to known what to take.
I work also with craniosacral therapy and myofascial release (the best one i have found to handle many body problems, cfs, fms and others).
