After several years on Metformin and suffering it's nasty side effects i decided to stop taking and tried Curalin. The results were astounding my long term blood sugar HbA1c test show a reduction from 80 (9.5 old) to 43 (6.1 old)my diabetic nurse was astounded,as was myself. Six months on i have just had my test done again and although results are not as good at 53 (7.0 old).i'm still within limits. I put the increase down to poor supply from Curalife and my lack of being able to get outside and be active due to the poor weather conditions we've had. So continuing with Curalin. Just wish the cost was lower.
