I started taking Master Formula over a year ago. I wish I had started sooner. After about a month taking just 1 packet a day, several things changed for me. The damage that Lyme disease caused in my brain, specifically cognition, lessened. I could think better and faster. Also, my senior memory has now decreased significantly. I remember a lot more now that I did before Master Formula (I also take Primal Omega 3). I can remember my early childhood right up to what I ate for dinner last night. I can remember the plots of movies and books! Today, because I'm on a fixed budget, I take one packet a couple times a week, and it's still working for me. I know this is anecdotal but I'm convinced this product is beneficial. I would rather buy this product than get take out - and since I love food, that's saying something!
