Although this product is a gel cap, unlike other forms of CoQ-10, this product is a "powder" mix, which tends to give me stomach gas with a bad after taste within a short time after ingesting. However, it's only temporary, and goes away within an hour or so. The price is average compared to store-shelf varieties, however, I must admit that I am a bit skeptical about this particular products potency compared to others, especially when used to help and/or eliminate angina..
I have been purchasing this product for nearly 2 years. I, my daughter and 90+ year-old mother all take it. It has helped relieve the "racing heart" that both my daughter and mother tended to experience. I have recommended this product to others I know with heart issues. It by no means is a cure-all but it has helped my family's hearts become healthier organs..
I started using this product in February to regulate my blood pressure. I am 40 years young and my blood pressure has fluctuated for a few years. At it's high it would be about 150/90. Too high for me, as I am at optimal weight, a non smoker, I don't drink alcohol and try to stay physically fit. My BP has dropped on average to 115/77. I can only attribute it to the COQ-10 that I take once a day..
