Study summary

Randomized, controlled, double-blind clinical trial with two parallel arms based on the product consumed (experimental product and placebo product) and conducted at a single center, to measure the efficacy of the liquid NUTIFOOD product (nutritional product with carob extract) on carbohydrate metabolism.

Read the detailed description

This study evaluates the effects of NUTIFOOD (liquid nutritional product with carob extract) on insulin sensitivity and carbohydrate metabolism in subjects with abnormal glucose or HbA1c levels not on antidiabetic medication, over 90 days.

Key assessments include: Glucose response (AUC and peak levels) during an oral glucose tolerance test. Changes in fasting glucose, HbA1c, and basal insulin. Insulin resistance measured by HOMA-IR and QUICKI. Effects on body composition. Safety and tolerability of the product.

The study aims to determine the potential of NUTIFOOD as a nutritional intervention to improve glucose regulation and metabolic health.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Subjects of both sexes aged 18-65 years.
  • Diagnosis of glucose intolerance according to the American Diabetes Association (at least one of the following criteria):
  • Impaired fasting glucose (100-125 mg/dl)
  • Impaired glucose tolerance (oral glucose tolerance test with 2-hour plasma glucose between 140-199 mg/dl)
  • between 5.7% and 6.4%
  • between 20-35 kg/m².
  • Stable dietary habits: no weight gain or loss greater than 5 kg in the last ten weeks.
  • Volunteers capable of understanding the clinical study and willing to comply with the study procedures and requirements.

Exclusion criteria

Exclusion Criteria:

  • Use of medications that may interfere with glucose metabolism.
  • Subjects with a history of any type of hepatic or renal disease.
  • Alcohol consumption greater than 20 g/day.
  • History of allergic or poor tolerance to any component of the study products.
  • Participation in another clinical trial within the three months prior to the study.
  • Lack of willingness or inability to comply with clinical trial procedures.
  • Pregnant or breastfeeding women.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

HbA1c

A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Study arms

  • Experimental
    Carob liquid - GippsNature

    Participants will consume two daily doses of the experimental product (liquid carob extract) for 90 days.

    Dietary Supplement: Experimental Product

  • Placebo comparator
    Placebo

    Participants will consume two daily doses of a placebo product with the same organoleptic characteristics as the experimental product for 90 days.

    Dietary Supplement: Control product

Interventions

  • Dietary supplementExperimental Product

    Participants will consume two doses per day. The product should be taken 30 minutes before the two main meals of the day.

    Also known as: Carob liquid - GippsNature

  • Dietary supplementControl product

    Participants will consume two daily doses of the placebo product. The product should be taken 30 minutes before the two main meals of the day.

    Also known as: Placebo

What researchers measure

Primary outcomes

  1. Glycated Hemoglobin (HbA1c)

    Fasting glycated hemoglobin (HbA1c) will be measured in venous blood samples to assess long-term glycemic control.

    Time frame: Measurements will be performed at baseline, Day 45, and Day 90

  2. Area Under the Curve (AUC) of Blood Glucose During Oral Glucose Tolerance Test

    The area under the curve (AUC) of blood glucose will be calculated during an oral glucose tolerance test (OGTT) using a 50-g glucose load. Capillary blood glucose levels will be measured at 0, 15, 30, 45, 60, 90, and 120 minutes after glucose ingestion.

    Time frame: This assessment will be conducted at baseline, Day 45, and Day 90.

Secondary outcomes

  1. Fasting and Post-Load Insulinemia

    Fasting venous insulin levels will be measured at baseline. Post-load venous insulin concentrations will be determined at 45 and 90 minutes during the oral glucose tolerance test (50-g glucose load).

    Time frame: These measurements will be performed at baseline, Day 45, and Day 90.

  2. Insulin Resistance

    Peripheral insulin resistance will be assessed using validated surrogate indices derived from fasting glucose and insulin levels: HOMA-IR (Homeostatic Model Assessment of Insulin Resistance)

    Time frame: They will be calculated at the start of the study, on day 45, and on day 90.

  3. Insulin Sensitivity

    Insulin sensitivity will be assessed using validated surrogate indices derived from fasting glucose and insulin levels: QUICKI (Quantitative Insulin Sensitivity Check Index).

    Time frame: It will be calculated at the start of the study, on day 45, and on day 90.

  4. Body Composition Analysis

    Body composition will be assessed using bioelectrical impedance analysis (BIA), providing estimates of fat mass, lean mass, and total body water.

    Time frame: These measurements will be performed at baseline, Day 45, and Day 90.

  5. Liver safety variables

    It is a blood test that measures the presence of some enzymes, proteins and bilirubin in the blood, with the aim of determining if there is any alteration in the liver. Enzyme GPT, GOT, Gamma GT, LDH, alkaline phosphatase and bilirubin (UI/L)

    Time frame: These measurements will be performed at baseline, on day 45, and on day 90.

  6. Adverse events

    It will be evaluated at each of the visits.

    Time frame: At 12 weeks after consumption
