Other ingredients include Cellulose (capsule), microcrystalline cellulose, silicon dioxide, and vegetable stearate.

The placebo utilized in this clinical trial will be formulated by the manufacturer to be as similar as possible to the active intervention in appearance, odor, and other key characteristics. Packaging for the control will be identical to packaging for the Active Comparator.

Prediabetic State

This study will assess changes in glycemic parameters and other biomarkers over a twelve week period, with two blood draws (Baseline and 12 weeks). Additionally, an IRB-approved research associate will call each study participant at the 6-week mid-point of the study to assess compliance and collect data on any adverse events.

RCT of a Polyherbal Dietary Supplement for Prediabetes

A Randomized, Placebo-controlled Clinical Trial of a Polyherbal Dietary Supplement (GlucoSupreme™ Herbal) on Markers of Glycemic Control Among Prediabetic Adults

Elevated fasting blood glucose is one of the markers of the prediabetic state. According to American Diabetes Association criteria, the prediabetic fasting blood glucose range is 100 to 125 mg/dL (5.6 to 6.9 mmol/L). After fasting for 8-12 hours, > 0.5mL of blood will be collected from each participant, followed by centrifuge separation of plasma from cells within 45 minutes of collection. After maintaining the plasma fasting blood glucose at room temperature, it will be analyzed using standard enzymatic methodology.

Elevated HbA1c is another one of the markers of the prediabetic state and is defined as being within the range of 5.7-6.4%. A four mL sample of whole blood will be obtained from participants using techniques described above, and placed in an EDTA, lithium heparin, or sodium fluoride tube, followed by analysis using the Roche Tina Quant (Roche, Germany).

In prediabetes, pancreatic beta cells can no longer produce enough insulin to overcome insulin resistance, which can cause blood glucose levels to rise above the normal range. Thus, fasting insulin is a glycemic parameter of interest and is also used to determine insulin resistance. While normal values for fasting insulin are <25 microU/L, fasting insulin can vary widely among prediabetic individuals. After fasting for 8-12 hours, 0.8mL blood serum will be obtained from each participant. This fasting insulin assay will be performed using a 2-site electrochemiluminescent immunoassay on the Roche automated platform (Roche, Germany.).

Insulin resistance often sets the stage for progression to T2D by placing a high demand on insulin-producing beta cells during a prediabetic state. The advantage of using the validated HOMA-IR calculation is its relative simplicity and low-cost since it is derived from other primary outcomes of interest in this study. HOMA-IR is calculated as: [Fasting insulin (microU/L) x Fasting Blood Glucose (nmol/L)]/22.5.

Pancreatic beta cells (β-cells) produce insulin. Thus, their function is of interest in this prediabetic study population. As is the case with HOMA-IR, this formula utilizes values from our other study outcomes. HOMA- β is calculated as: (20 x Fasting insulin [microU/L])/(Fasting blood glucose [mmol/l] - 3.5).

The validated QUICKI measurement to assess insulin sensitivity has also been studied in herbal dietary supplement clinical trials. QUICKI is calculated as: 1/(log-fasting blood glucose [mg/dL] + log-fasting insulin [uU/mL]).

Many serum proteins are involved in glucose synthesis. Fructosamine represents the degree of glycation in these proteins, and is the concentration of plasma glucose over the lifetime of the protein. This useful test has been utilized in previous clinical studies of natural products3 4 and is an adjunct to the A1C and other fasting glycemic measurements, and reflects intermediate-term (previous 2-3 weeks) glycemic change. One mL of serum or plasma will be collected, followed by centrifuge separation within 45 minutes of collection, and analyzed using standard colorimetric assay methodology (LabCorp, Inc.).

A blood test commonly used in clinical practice to determine peak hyperglycemia. The GlycoMark test provides accurate recognition of recent glycemic deterioration or improvement (within the previous 2-4 weeks)5 6 and is commonly given adjacently to A1C (a longer-term indicator of glycemic change) in clinical practice. One mL of serum or plasma will be collected, followed by centrifuge separation within 60 minutes of collection, and analyzed using standard enzymatic colorimetric assay methodology (LabCorp, Inc.).

A standard lipid panel consisting of total cholesterol, LDL, HDL, and triglycerides will be compared at baseline and the 12-week follow up visit. One mL of serum or plasma will be collected for all lipid parameters after 8 -12 hours of fasting and in the manner as described above, followed by centrifuge separation within 45 minutes of collection, and analyzed using standard enzymatic methodology (LabCorp, Inc.).

High-sensitivity C-reactive protein (Hs-CRP) is a common measure of inflammation that is commonly collected in clinical practice. Samples will undergo analysis by latex immunoturbidimetry on a COBAS Integra 800 (Roche, Germany).

This study is a 12-week, randomized, double-blinded, placebo-controlled clinical trial of GlucoSupreme™ Herbal. Eligible participants will be recruited from within participating clinical practices. All study outcomes will be biomarkers, capturing normal structure and function of the human body, derived from blood draws ordered during two physician visits spaced 12 weeks apart. This is a typical interval between blood assessments of glycemic control in routine clinical practice. An IRB-approved research associate will call each study participant at the 6-week mid-point of the study to assess compliance and collect data on any adverse events. Serious adverse events, while not anticipated, will be reported by the participant to a study physician as soon as possible.

The study products will be delivered to the investigative sites prior to enrollment of subjects. A study code will be provided for every batch of study product shipped to the investigational site prior to the beginning of the study. The placebo utilized in this clinical trial will be formulated to be as similar as possible to the active in appearance, odor, and other key characteristics, and packaging for both intervention and placebo will be the same. The de-identified study product will be packaged and labeled according to the study code and participant identification numbers; the Study Coordinator will oversee a locked master list of these, in addition to batch numbers.

after 4 weeks of lifestyle advice and changes, all subjects will receive for 8 weeks the administration of CARDIOVIS COLESTEROLO 3 mg, a nutraceutical compound containing containing red rice fermented with Monascus purpureus titrated with 3% monacolin K, hydrol mixture of olive fruit titrated with vitamin E, Coenzyme Q10 and polymethoxyflavones

Subjects that meet the inclusion/exclusion criteria and have provided informed consent will undergo a 4-week period of lifestyle advice and changes. If, after the 4 weeks, LDL values are confirmed above the established cutoffs, the subjects receive CARDIOVIS COLESTEROLO 3 mg for 8 weeks. After the 8-week treatment period, all biological paprameters will be reassessed. Finally, a last blood samples to assess a potential rebound effect after nutraceutical suspension is collected 4 weeks after the treatment stop.

Follow the previous administration program，participants will continue to receive 20mg Atorvastatin daily or 10mg Rosuvastatin daily; Besides taking statins, Participants will receive 500mg berberine twice a day for 8 weeks.

Due to the different clinical prescriptions by different doctors and similar Efficacy in lowering lipids.Usually,Participants receive 20mg Atorvastatin daily or 10mg Rosuvastatin to treat hyperlipidemia.
