Excellent!Love this product. Been giving to my elderly parents and it helped them with their alertness and general wellbeing. Taking this myself, it it definitely helped with my alertness and focus at work. For those who might be more prone to "heatiness", perhaps 1 capsule/day might be sufficient. Great product!
It’s great. I used to experience headaches and because I am a teacher, I have to stand for along time. Now there is no fatigue.
