I purchased this for my husband to try. He is diabetic and his numbers would be pretty high in the mornings when he would wake up. His AC1 numbers and his numbers during the day were all fine but he just could seem to do anything about his waking numbers being elevated. After checking with his doctor, he started taking these tablets at night before going to bed and his numbers are starting to slightly improve. He says that they are easy to take and does not leave any aftertaste after taking them. He will continue to take them and I will update after he sees his doctor again in a month.
