The ancient methods of healing are still viable today and if we're willing to do the research and try things out, we can live healthier using natural substances. 

For example I'm now taking Magnesium glycinate, milk Thistle w dandelion, and powdered black seeds (Nigella Sativa) to control my blood sugar. I have been in the pre-diabetic range for my A1C for about 10+ years now and although it has been coming down, I have been on Metformin for most of that time and it is really not good for your body. It has side effects and doesn't actually do anything to fix your blood sugar or insulin production. 

These supplements are keeping my blood sugar in the normal range, even after waiting for the Metformin to leave my bloodstream (4 days minimum), and I will get my A1C tested again in December. Most likely it will be reduced to the normal range.
The supplements have also lowered my blood pressure to the normal range, which is a great side effect. I learned about the supplements from the site and the specific page for diabetes is:
