NCT06224803

Brief Summary

At present, diabetic patients mainly use drugs to control blood sugar. However, drugs have side effects and the control effect varies among individuals. Even if diabetic patients can control their blood sugar well, long-term medication will still cause a series of complications, including retinopathy, nephropathy, diabetic foot, heart disease, etc. Vascular disease issues, etc. This study will focus on the changes in HbA1c and blood sugar in patients with confirmed diabetes after taking "Dibifree®" food supplement.

Outcome Measures

Primary Outcomes (2)

  • Concentration of HbA1c

    Hemoglobin A1c (HbA1c) levels were measured at baseline (V0) and routinely monitored at the third (V3), fourth (V4), and seventh (V7) months. For longitudinal analysis, repeated measures were evaluated using two-way ANOVA followed by Sidak's multiple comparisons test to assess time and treatment effects. Data are presented as mean ± SD. All statistical analyses were performed using GraphPad Prism 10 (GraphPad Software, San Diego, CA, USA). All data were considered statistically significant at p ≤ 0.05.

    HbA1c was measured at baseline (V0) and during follow-up visits at months 3 (V3), 4 (V4), and 7 (V7) after intervention.

  • Body Weight and BMI

    Changes in body weight and BMI between baseline (V0) and month 7 (V7) were analyzed using an unpaired t-test. Statistical analyses were conducted using GraphPad Prism 10 (GraphPad Software, San Diego, CA, USA), with p ≤ 0.05 considered statistically significant.

    Body weight and BMI were measured at baseline (V0) and at the end of the 7-month intervention (V7).

Secondary Outcomes (4)

  • Concentration of Blood Sugar

    measured at baseline (V0) and during follow-up visits at months 3 (V3), 4 (V4), and 7 (V7) after intervention.

  • Kidney Function Parameters: BUN, Creatinine, and eGFR

    Kidney function parameters measured at baseline (V0) and during follow-up visits at months 3 (V3), 4 (V4), and 7 (V7) after intervention.

  • Liver Function Parameters: GOT and GPT

    Liver function parameters measured at baseline (V0) and during follow-up visits at months 3 (V3), 4 (V4), and 7 (V7) after intervention.

  • Concentration of blood lipid

    The measurement at baseline (V0) and during follow-up visits at months 3 (V3), 4 (V4), and 7 (V7) after intervention.

Study Arms (2)

Dibifree

EXPERIMENTAL

Participants were instructed to consume ten Dibifree capsules each time, 5 to 10 minutes before meals, three times daily, for three months. This course of treatment was followed by a one-month washout period, after which Dibifree was resumed for an additional three months.

Dietary Supplement: Compound plant extracts

Control

PLACEBO COMPARATOR

Participants were instructed to take ten starch-containing placebo capsules 5 to 10 minutes before meals , three times daily, for three months. This was followed by a one-month washout period, after which participants switched to Dibifree treatment at the same dosage as the experimental group for another three months.

Dietary Supplement: Indigestible dextrin

Interventions

Compound plant extractsDIETARY_SUPPLEMENT

Total supplement including bitter melon (Momordica charantia) fruit extract, celery (Apium graveolens) seed extract, baker's yeast (Saccharomyces cerevisiae) cell wall extract, acerola (Malpighia emarginata) fruit extract, grape (Vitis vinifera) seed extract, green tea leaf extract, and hydrolyzed soy protein powder.

Model Details: Baseline physical examinations were conducted at the time of inclusion (V0), including assessments of fasting and postprandial blood sugar, HbA1c, body fat, blood urea nitrogen (BUN), creatinine (CRE), estimated glomerular filtration rate (eGFR), total cholesterol, HDL-cholesterol, LDL-cholesterol, Glutamic Oxaloacetic Transaminase (GOT), and Glutamic Pyruvic Transaminase (GPT). These parameters were routinely monitored in the third month (V3), fourth month (V4), and seventh month (V7). No adjustments were made to the diabetic routine medications during the clinical trial period.
