I have only been on the Memory Formula for a few days, but can already see an amazing difference in my mental abilities. Not only do I remember lots more, I feel much more positive about almost everything. I am cheerful and upbeat most of the time now. I am crippled myself, and my husband lost both his legs two years ago, and I am his caregiver. Our whole life changed, and now coping is much easier. Thanks for this product. I do not want to ever be without it.
