“Definitely the best focus enhancing supplement I’ve taken. It’s subtle, calm focus which I was looking for. Most brain enhancing formulas are too intense and give me too much energy. I do have a sensitive system so this was just perfect. I finished my first bottle and after about a month without I noticed I was back to were I started and decided it was time to order the value pack. I took as directed with no negative effects. I noticed a difference in the first few days of taking it.”
