Effect of a Protein-Creatine-Omega3-Vitamin D Supplement on Glycemic Variability in Mexican Patients With Type 2 Diabetes

Participants will receive a daily powdered supplement containing 30 g of whey protein isolate, 5 g of creatine monohydrate, 1 g of omega-3 fatty acids (EPA/DHA), and 1,000 IU of vitamin D3. The supplement will be taken once daily for 12 weeks, dissolved in water. It is designed to reduce glycemic variability and improve metabolic parameters in individuals with recently diagnosed type 2 diabetes.

Participants will receive a daily powdered placebo formulated with maltodextrin, without any active ingredients (no whey protein, creatine, omega-3, or vitamin D). It is identical in appearance, taste, and packaging to the active supplement. It will be taken once daily for 12 weeks and administered in the same conditions as the intervention group.
