My energy level has increased a lot, I feel less tired in the evening and am generally better mood, creative and full of power. That was the dietary supplement that has been missing. Years ago, I had already discovered GSD vitamin D for me and already experienced a significant improvement in my condition since, colds since belong to the past, joint complaints improved. OPC and a healthy diet (the waiver and the severe restriction of sugar) has me again gegeben- a strong upswing kanns I highly recommend!
