This study aims to evaluate the effect of a daily nutritional supplement containing whey protein, creatine, omega-3 fatty acids, and vitamin D on blood sugar fluctuations in adults with recently diagnosed type 2 diabetes. Forty participants will be enrolled in a 12-week, double-blind, randomized clinical trial. Half of the participants will receive the supplement, while the other half will receive a placebo. Blood sugar levels will be monitored using continuous glucose monitoring (CGM) devices placed at five different time points during and after the intervention. The study will also measure changes in HbA1c, body composition, metabolic biomarkers, and gut microbiota. Participants will receive medical follow-up and support for six months after the study. The goal is to explore whether this supplement can help stabilize glucose levels and support early management of diabetes.
This randomized, double-blind, placebo-controlled clinical trial will evaluate the impact of a combined supplement-composed of whey protein, creatine monohydrate, omega-3 fatty acids (EPA/DHA), and vitamin D-on glycemic variability in Mexican adults recently diagnosed with type 2 diabetes (diagnosis within the last 5 years, HbA1c 7.0-10.0%, treated with metformin or no pharmacologic therapy).
Forty participants will be randomized (1:1) to receive either the active supplement or placebo for 12 weeks. Glycemic variability will be assessed through five time points using continuous glucose monitoring (CGM) with FreeStyle Libre sensors. Secondary outcomes include changes in HbA1c, fasting glucose, anthropometric data (via InBody H30), metabolic and inflammatory biomarkers (Bio-Plex Pro Human Diabetes 10-Plex Assay), and gut microbiota composition (via 16S rRNA sequencing in collaboration with the University of Illinois at Chicago).
The study also includes biweekly clinical assessments to monitor adherence and safety, and a final post-intervention follow-up phase four weeks after supplementation ends. All participants will receive six months of free medical follow-up. The study is designed to explore the feasibility of using CGM and multi-nutrient supplementation as part of early, non-pharmacological strategies to improve glycemic control in Latin American populations.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Supplement Group | Experimental | Participants assigned to this arm will receive a daily nutritional supplement for 12 weeks. The supplement will be provided in powdered sachets 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. Participants will dissolve the sachet in water and consume it once daily. Glycemic variability will be assessed through continuous glucose monitoring at five time points, and clinical evaluations will be performed biweekly. |
|
| Placebo Group | Placebo Comparator | Participants in this arm will receive a daily placebo for 12 weeks. The placebo will be formulated with maltodextrin and will be identical in appearance, taste, and packaging to the active supplement. It will not contain whey protein, creatine, omega-3, or vitamin D. Participants will dissolve the sachet in water and consume it once daily. Glycemic variability and all other outcome measures will be assessed in the same schedule and manner as in the intervention group. |

| Protein-Creatine-Omega-3-Vitamin D Supplement | Dietary Supplement | 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. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in Glycemic Variability | Change in Standard Deviation of Glucose Values (mg/dL) | Baseline, Week 4, Week 8, Week 12, and 4 weeks post-intervention (Week 16) |
| Change in Coefficient of Variation of Glucose (%) | The coefficient of variation (CV) of glucose levels will be calculated from CGM data to evaluate glycemic variability, reflecting the ratio between the SD and the mean glucose concentration during the monitoring period. | Baseline, Week 4, Week 8, Week 12, and Week 16 (4 weeks post-intervention) |
| Change in Time in Range (TIR, % of time between 70-180 mg/dL) | Time in Range (TIR) will be defined as the percentage of time that CGM glucose readings remain within the target range of 70-180 mg/dL. This measure will help assess overall glycemic control during and after the intervention. | Baseline, Week 4, Week 8, Week 12, and Week 16 (4 weeks post-intervention) |
| Measure | Description | Time Frame |
|---|---|---|
| Change in Hemoglobin A1c (HbA1c) | Glycated hemoglobin (HbA1c) levels will be measured at baseline and post-intervention to assess long-term glycemic control. | Baseline and Week 12 |
| Change in Total Fat Mass (kg) |
