People looking for natural herbal support for blood sugar and lipid levels can consider a good cinnamon herbal extract to use along with lifestyle changes like improving their diet, losing weight and exercising. In terms of herbs, cinnamon is a good candidate as ongoing research is showing beneficial effects on blood sugar/insulin levels, and possibly blood lipids like cholesterol too. NOW Foods Cinnamon Bark would be a great choice given NOW's reputation for quality ingredients and the fact that the quality of cinnamon varies so widely.
