My wife and I have been taking Superbeats for approximately 18 months now. While it is not the only lifestyle change we have made, ie eating more fruits, veggies, legumes, oats, and nuts, we have had very good results regarding reduced blood pressure. The nitric oxide benefits do work. I feel significantly better. My bloodwork is all back in spec, and I was a typical person on high blood pressure and cholesterol meds and high A1C. Also had significant pain from inflammatory arthritis. Of course, I cannot say it was only the super beats that has helped. But I will absolutely continue and recommend taking superbeats!
