Been on and off these supplements for a year to see if they actually work. I must say I feel a difference when taking them... when using thos product I'm able to cope with daily stress and finish the day on a positive note more often. I've noticed shaper mental preformance and a higher level of attention to detail... the only thing I'm upset about is not getting more ie. The 6 months subscription which I will be opting for rather than the 3 months supply. A must have for well-being conscious folks.
