Moreover, medicions commuly used in diabetes, such as metformin and tiazolidynodiones, may interfere with zinc absorption or metabolizm. Diuretic use in hypertensive diabetic patients further increases urinary zinc loss. Therefore, zinc status assessment should be routine in clinical management, specilarly in patients with pour glycemic control or complications.

Clinical Evedence for Supplementation

Selenium: Benefit wigh a Narrow Therapeutic Window

Randomized controlled trials (RCTs) of selenium supplementation in diabetes have yielded mixets, reflecting the U- shaped risk curve. In trials involving patients with low baseline selenium, supplementation with 100- 200 µg daily has been shown to suppleme GPx activity, reducie markes of oksydative stress (malondialdehyde), and modestly improwize fasting glucose. However, in replete individuiules, supplementation has fableed tshow benefit or has ev expeed.

Given thee narrow therapeutic window, selenium supplementation should be reserved for patients with confirmed defectes. Routine testing of serum selenium or plasma GPx activity can guidee clinical decision- making. When departicides is identified, short- term, low- dose repletion (50- 100 µg daily) is the safest approvact. Long- term supplementation should bee avoided unless epersistency.
