Product created by Nuttrition For Life International out of Texas. I sell and personally use this product.
I have tried similar products from GNC and over the counter nutritionals from stores and other nutrition supplement companies. I find that MemTabs helps me focus better and think clearer, it works for me faster than any other similar product I have tried from other companies.
I load up on it when I need to study or learn new material for work. If you take it every day you will notice a differance in your concentration and mental energy level.
There are other products from the same company I use to suplement brain function along with MemTabs. It does work if you take it regularly.
No side effects either, unlike some products I have tried out there.
