Study
Chromium Supplementation May Improve Insulin Resistance in Older Adults with Type 2 Diabetes
A study found that taking 400 micrograms of chromium daily can reduce insulin resistance in adults over 40 with type 2 diabetes.
Summary
In plain language
Recent research has shown that supplementing with chromium can help improve insulin resistance in older adults with type 2 diabetes. The study involved adults over the age of 40 who took 400 micrograms of chromium daily for eight weeks. While the chromium supplementation did not significantly lower fasting blood glucose levels, it did result in a noticeable reduction in insulin resistance. This finding is important because managing insulin resistance can help prevent further complications associated with diabetes. Seniors with type 2 diabetes may want to discuss with their healthcare providers whether chromium supplementation could be a beneficial addition to their diabetes management plan.
Details
Use the full description to understand the study design, methods, and the limits of the findings.
This study was a controlled trial where participants with type 2 diabetes were given chromium or a placebo for eight weeks. Researchers measured cholesterol and insulin resistance, finding improvements in those taking chromium.
The study found a significant reduction in total cholesterol and insulin resistance in the chromium group.
No significant changes were observed in fasting blood glucose or body weight.
The study had a small sample size, and results may differ with larger groups or higher doses.
Seniors should discuss adding chromium supplements with their healthcare providers, especially if managing diabetes.

Treatments Evaluated in This Research
Review the interventions studied here and compare them against the broader treatment library.
Supplements
Supplements help fill nutritional gaps and support healthy aging. For seniors, vitamins, minerals, and omega-3s can enhance bone strength, heart health, energy, and immune function when used safely under professional guidance.
Insulin Therapy
Insulin therapy replaces or supplements the body’s natural insulin to regulate blood sugar levels. For seniors, it helps maintain stable energy, prevents complications, and supports overall wellness when used as part of a comprehensive care plan.
Chromium Picolinate
Chromium picolinate is a highly bioavailable form of the essential trace mineral chromium. It supports healthy glucose metabolism and insulin sensitivity, playing a key role in carbohydrate, protein, and fat metabolism.
