I have taken those other "brain health" products for a couple of years now, and have not really experienced anything extraordinary............until I started taking Advanced Bionutritionals Memory Formula. NOW I have! I started actually noticing a definite difference within a couple of days. There was a noticeable difference in my cognitive function.....I'm able to recall things from not only long ago, but from recently, also....which means that my short-term memory is back! Thank you, for this marvelous breakthrough in brain health!!!
