I want to start my supplement course due to my brain condition. Is it safe?
Hi PercyHolmes and welcome to the forum. One of the things we can't do here is diagnose or tell you that a particular course of action is "safe" or not. We can and will give our personal experiences and provide referenced information.
However I think it would not be right for anyone here to try to advise you on the basis of the limited information you've given - nobody knows what a "supplement course" entails and equally a "brain condition" could be many things.
My advice to you would be to talk to your doctors about this.
