Although the use of cinnamon is well studied, the various types and extracts and wide range of doses mean that the conclusions are not uniform. Neither the National Center for Complementary and Integrative Health (NCCIH) nor the American Diabetes Association recommends the use of cinnamon supplementation. Newer studies of chromium picolinate concluded that the supplement does not ameliorate insulin resistance or impaired glucose metabolism. At best, when changes in glucose metabolism are observed, individual patient phenotypes may be a factor. Most studies of fenugreek have lacked sufficient power or quality to conclude any recommendations in diabetic patients.
A systemic review and meta-analysis of 16 trials found that ginseng modestly yet significantly improved fasting blood glucose in people with and those without diabetes. Ongoing research is being conducted by the NCCIH on the potential of standardized ginseng preparations in treating insulin resistance.
