I've noticed I was in a brain fog for a few months so I decided to give this a try. On the very first day I noticed a difference of being a little less foggy. I took them around 8am & by about 10am I noticed a difference but it didn't last all day. By 8pm I was back to being foggy. Hopefully over time this will build up in my system & the unfogginess will last all day. Will update when the bottle is gone.
