Prior to taking this product, I was having a problem trying to remember things, the simplest things. I thought I was getting Alzheimer so I had a brain scan and MRI performed. That’s how serious it was. All tests came back negative but something was definitely wrong. My wonderful daughter was worried about me and suggested that my body probably was lacking some very important nutrients. So when searching for something to take, I came across this product. This is my third bottle, and I tell you this has given me energy and my memory back and iHerb is a blessing to order from you.
