The best supplement for your brain
I don't expect to rely on the wisdom of Donald Trump for anything. However, I recently heard him giving an interview to Sean Hannity of Fox News. In that interview he was talking about a supplement that helped him function as well as he does at his age of 73 in his position as the President of the United States.
Although he did not divulge the brand name it seemed to be Neuro-Peak, which is a supplement that I purchase on Amazon.com. It is much less expensive than Prevagen and works better for me.
