Micronutrients & recovery
High body iron stores (indicated by high serum ferritin) are positively correlated with an increased risk of developing Type 2 Diabetes and insulin resistance, likely due to oxidative stress.
If you have high ferritin levels, discuss with your doctor whether reducing iron intake or therapeutic phlebotomy might help lower your diabetes risk. High iron stores can contribute to oxidative stress and insulin resistance, so managing iron levels is a valid strategy for metabolic health.
ModerateSupportsMEDIUM confidence
Iron is a strong pro-oxidant and the association of increased level of oxidative stress with high body iron levels can increase the risk of T2DM.
Why this rating
Based on multiple observational and cohort studies showing correlation, but causality is complex and influenced by other factors.

- Deficiencies in trace elements (specifically magnesium, zinc, chromium, and selenium) are associated with impaired glucose metabolism and insulin resistance, while supplementation or restoration of these levels can improve insulin sensitivity and glucose tolerance.Moderate
- Selenium status has a complex, non-linear relationship with diabetes risk, where both deficiency and excess (high serum levels) may be associated with adverse metabolic outcomes depending on geographic and baseline status.Limited
