I take megadoses of this stuff to match the literature suggesting enhancement of cognition in healthy humans. It takes about 12 weeks before you will notice anything according to the medical literature. I am at 700mg 2 times per day and am now at week 12. In addition to being less stressed and having less anxiety, I notice that I am much quicker to process auditory information. Bacopa (along with ashwagandha) is a long term KEEPER.
