I really like the taste of the product, though I initially had great difficulty getting the package of coffee open. I've tried the powder in tea, hot water, smoothies and in a diluted juice. I haven't noticed any effects as yet. I will have an A1c reading in three months. My blood pressure has been steady, controled by diet and a low dose of Irbesartan. I withold judgement until I've been enjoying it for a longer period of time.
