Berberine HCl
Found in barberry, goldenseal, goldthread and Oregon grape. NCCIH reports a 2021 review of 46 studies (4,158 people) in which berberine may have lowered blood glucose, reduced insulin resistance and improved lipids in type 2 diabetes (NCCIH). A 2008 clinical trial and a 2022 meta-analysis support this (PubMed; PubMed). See berberine for blood sugar.
Chromium picolinate
Chromium is an essential trace mineral; with too little, your body can’t use glucose efficiently. NCCIH cites a 2022 review of 16 studies suggesting it may help HbA1c, fasting glucose and insulin resistance. See chromium picolinate and insulin.
