The five supplements mentioned above – vitamin E, St. John's wort, ginseng, niacin, and chromium – all have the potential to interfere with blood sugar control or interact with diabetes medicines. That said, other supplements may boost your health, like omega-3s, which get excellent reviews.
We found strong correlations between markers of iron metabolism and markers of insulin resistance. Our results suggest that lower plasma levels of available iron, not excessive body iron stores, seem to be linked with glucose dysregulation. Inflammation and/or obesity may play a key role in this context.
Too much iron in the body is believed to have an effect on how the body breaks down sugar in the blood – and could be a potential risk for developing type 2 diabetes, ing to a new study.
Iron supplementation increased hepatic iron and serum hepcidin fivefold and led to a 40% increase in fasting glucose due to insulin resistance, as confirmed by the insulin tolerance test, and to threefold higher levels of triglycerides.
The link between iron and diabetes was first recognized in pathologic conditions—hereditary hemochromatosis and thalassemia—but high levels of dietary iron also impart diabetes risk. Iron plays a direct and causal role in diabetes pathogenesis mediated both by β-cell failure and insulin resistance.
