Be honest, I have chosen your brand because of the flexible dose.To me the 1200mg daily is perfect dose. (It all depend on personal weight).
Last time , I took 500mg x2 daily. It seems not strong enough. 1500mg( 3 capsules) makes me nausea. With light weight person, May start with 800mg daily to try how you feel. Also, the color looked very pure to me when I opened. Once I like the product, I will stick with the same brand, Because your body get used to it.
Also, I don't have diabetes. I have high Cholesterol and high Triglyceride. When you finish one bottle 40days. The blood test result is stunning.
