Good Results
I am not a doctor, but I can attest that Qunol Brain Health Focus Plus is working for me. I must confess that I am no spring chicken and was experiencing memory problems that go along with aging. Furthermore, my doctor has me wearing an oxygen tube, and I was worrying about what happens to my brain when something goes haywire in that department. I began to search for an OTC product that might help and noticed that the claims of one product widely advertised on TV were not supported by research while Qunol does have scientific support. I've used the product for several months now and have indeed noticed a decrease in my symptoms. I feel confident recommending the product to others in the same situation.

Useless
Of all the supplements I've tried, this was the biggest waste of money. I just finished the bottle and honestly can say I gave it a good shot, but really it is as useless for memory as a multivitamin would be. Furthermore so expensive and each dose is 2 hard white pills. I've been using brain supplements since college and literally this is useless.

It works
This kind of product is always hard to rate, Does it work, or doesn't it. Am I aware of having it onboard, or is it my hopeful imagination? Who knows? But for both of us, I feel as though I am more aware in general but most important to me is that I have more energy to accomplish things. Does a more active brain lead to more physical stamina? I don't know, but I do know what I feel and it is great for both us 70++ year olds.

Another of Hayes’ incredible tools for healing
Format: Paperback
Incredibly informative! I have followed Dave Hayes for years. Much of what he refers to in this book is familiar particularly the concept of controlling your own well being through Jesus and our Heavenly Father. I am delighted with Hayes’ ability to break down the often nebulous and overlapping states of being that we should be able to perceive but often cannot, enabling us to change and heal. Another bravo to this practical, articulate, generous Christian author anchoring it all in the Word.

Excellent Knowledge on spiritual warfare.
This book is Great Educational Material if your willing (Especially as a Christian) to fight in the daily spiritual warfare. It shows you how to spot the invisible enemy that tries to Seek, Kill & Destroys lives. Praying Medic's Books are Excellent! Also bought his other books the Lord said to buy his book on Healing. Thus saith the Lord, "My people are destroyed because of LACK of KNOWLEDGE."
