Chromium
TL;DR
Essential trace mineral that enhances the action of insulin
Moderate evidence for improving glucose control in diabetics
May help reduce 'carb cravings' and support weight management
Very safe at standard doses
Extremely cheap: ~$5-8/month
Best for: Pre-diabetes, sugar cravings
What it is
Chromium is a mineral we need in very small amounts. It is a key component of 'Chromodulin,' a protein that helps the insulin receptor work more effectively. Essentially, chromium helps 'unlock' the cell door so insulin can let glucose in.
Most people get enough from food (broccoli, oats, barley), but those with high-sugar diets or processed food intake may have lower-than-ideal levels. Chromium Picolinate is the form used in most studies due to its superior absorption.
What the research says
Chromium's best data is in populations with poor glucose control. Insulin Sensitivity. A review of 25 trials showed that chromium supplementation improved glycemic control in patients with Type 2 diabetes. Craving Control. Some studies, including one in the Journal of Psychiatric Practice, suggest that 600-1,000 mcg of chromium can reduce carbohydrate cravings and binge eating in those with atypical depression. Weight Loss. While marketed as a weight loss aid, the actual fat-loss benefit is very small—usually less than 1-2 pounds over several months.
