The maximum recommended doseage for ginger is 4 gm daily. Each 1 inch cube of crystallized ginger has 500 mg ginger. So, you should not exceed 8 one-inch cubes of crystallized ginger to help drive fasting blood sugar down. NOTE: A CUP OF GINGER TEA HAS ABOUT 250 MG GINGER, MUCH LESS THAN THE CRYSTALLIZED GINGER. IT WILL ALSO LOWER FASTING BLOOD SUGAR IF TAKEN RIGHT BEFORE BED, SO IT IS THE MILDER APPROACH.
However, please note that too much ginger can make blood on the brain, as ginger reduces platelet stickiness and thins the blood. So, people that are on blood thinners should probably not take ginger in any form.
But it continues to drive my fasting blood sugar down. I am not taking blood thinners and am very glad to have this information. The 30 carb grams in 1 ounce of crystallized ginger just disappear overnight, so you don't have to count them in your daily targets.
