Chromium and Blood Sugar: What the Studies Actually Show

Chromium is a trace mineral your body needs in tiny amounts. It is sold for blood sugar because it seems to help insulin do its job.

The Daily Value for adults is 35 mcg (NIH ODS: Chromium). Chromium picolinate is one common form, and it is the form printed on the Sugar Reset label.

The sales page says the formula can "promote healthy insulin function". That is marketing. The label itself only says "Promotes Metabolic Balance". The real question is whether extra chromium, on top of food, changes blood sugar in people with diabetes.

They found small drops, and nobody is sure those drops matter. A 2019 review pooled 58 trials in type 2 diabetes (NIH ODS: Chromium). Fasting glucose and A1C came down a little on average. The NIH calls the clinical meaning unclear.

Another NIH center read the same field and saw a mixed picture. Chromium "may be able to provide some benefit", it says, but the research shows conflicting results (NCCIH Clinical Digest: Type 2 diabetes and supplements). Doses ranged from 200 to 1,000 mcg, and many trials were small and short.

Yes, at supplement doses. The NIH says chromium may add to insulin and other diabetes drugs, raising the chance of a low (NIH ODS: Chromium). It may also cut how well you absorb levothyroxine, a common thyroid pill.

The 1.4 mcg in Sugar Reset is far below the doses behind those warnings. The unknown amounts of gymnema and ginseng are the bigger reason to show your doctor the bottle.

1. Chromium: Fact Sheet for Health Professionals. NIH Office of Dietary Supplements, 2026.Daily Value is 35 mcg; chromium-only supplements usually give 200 to 500 mcg (up to 1,000 mcg), and diabetes trials used 200 to 1,000 mcg/day. A 2019 review of 58 trials found small drops in fasting glucose and HbA1c of unclear clinical meaning. Chromium may add to insulin or other diabetes drugs and raise hypoglycemia risk, and may reduce levothyroxine absorption.
2. Type 2 Diabetes and Dietary Supplements: What the Science Says. National Center for Complementary and Integrative Health (NIH), 2022.Chromium "may be able to provide some benefit for improving glycemic control, but the research shows conflicting results," and there is not enough evidence that any dietary supplement can help manage or prevent type 2 diabetes.
3. 5. Facilitating Positive Health Behaviors and Well-being to Improve Health Outcomes: Standards of Care in Diabetes-2026. American Diabetes Association Professional Practice Committee, Diabetes Care (Suppl 1), 2025.Recommendation 5.16 (grade C): supplementation with micronutrients (such as magnesium or chromium) or herbs or spices (such as cinnamon and aloe vera) "is not recommended for glycemic benefits"; the text says evidence is insufficient to support herbal supplements or chromium to improve glycemia.
4. Low Blood Glucose (Hypoglycemia). National Institute of Diabetes and Digestive and Kidney Diseases (NIH), 2021.For many people with diabetes, low blood glucose means below 70 mg/dL; it can be a side effect of insulin, sulfonylureas or meglitinides. Treat with 15 to 20 grams of glucose or carbohydrate, recheck after 15 minutes; severe lows can cause seizures or loss of consciousness and need glucagon or 911.
