Study summary

This study is a randomized, double-blind, placebo-controlled, parallel-controlled trial (24 weeks in total), divided into three periods (screening, treatment, and discontinuation follow-up)

Read the detailed description

This trial is a randomized double-blind human trial, mainly to investigate the effect of long-term consumption of red yeast rice products on reducing glycated hemoglobin (HbA1c) and regulating blood sugar. It is expected to recruit 80 subjects for a period of 24 weeks. The test group takes 2 capsules of red yeast rice per day (Each capsule contains 440mg ANKASCIN 568-P), the control group took placebo capsules daily, blood samples were collected for biochemical analysis at 0, 4, 12, and 24 weeks, and the general body position measurement, blood pressure, Blood lipids, blood sugar and other related changes, and monitor liver, kidney, thyroid function.

Inclusion criteria

  1. Men or non-pregnant women over 20 years old (women of childbearing age are not allowed to become pregnant or breastfeed during the study) adults who are sane and able to communicate.
  2. 18≦BMI≦35.
  3. Blood routine examination (CBC; Complete blood count): the mean corpuscular volume MCV should not be less than 70 fL.
  4. Blood glucose level measurement meets any of the following conditions:

(1) The fasting blood sugar is between 100∼125 mg/dL, and the doctor judges that there is no need to use hypoglycemic drugs for the time being.

(2) Or the glycosylated hemoglobin is between 5.7∼6.4%, and the doctor judges that the use of hypoglycemic drugs is not needed for the time being.

(3) Diabetic patients who have no willingness to take medicine and have not taken hypoglycemic drugs in the past month.

5. Those without other serious diseases (cancer, heart failure, myocardial infarction, liver cirrhosis, moderate to severe liver and kidney dysfunction, stroke, etc.).

6. Hypoglycemic drugs are not allowed to be used during the trial. If the condition changes and the use of hypoglycemic drugs is required, the trial must be withdrawn.

7. During the test period, the daily routine and eating habits should be maintained without deliberately changing them.

Exclusion criteria

Exclusion Criteria:

  1. Blood pressure: systolic blood pressure ≧ 200 mmHg or diastolic blood pressure ≧ 140 mmHg.
  2. Moderate or severe liver and kidney dysfunction (generally refers to serum aminopyruvate converting enzyme (SGPT) and serum glutamate phenylacetate transaminase (SGOT) are more than 3 times higher than the upper limit of normal value or have been diagnosed Liver cirrhosis, or glomerular filtration rate eGFR≦30 ml/min/1.73m2).
  3. Pregnant or lactating women.
  4. Diabetic patients taking hypoglycemic drugs or insulin injections.
  5. Those who take traditional Chinese medicine mainly red yeast rice.
  6. Have undergone surgery within one month.
  7. Combined with serious diseases such as heart, liver, kidney and hematopoietic system, mentally ill patients who do not meet the inclusion criteria, who do not eat the test samples according to the regulations, so that the efficacy cannot be judged or the incomplete data affect the judgment of efficacy or safety.

Study arms

  • Experimental
    ANKASCIN 568-P Red yeast rice capsules

    ANKASCIN 568-P is a fermented product from the red yeast rice fungus \<Monascus purpureus NTU 568\>. It does not contain Monacolin K, an ingredient that may harm the human body, and is rich in new active ingredients. Take 2 red yeast rice capsules (each containing 440mg ANKASCIN 568-P) every day, and the control group takes 2 placebo capsules (containing equal weight maltodextrin) every day, respectively, at the 0th, 4th , , 12, 24, Collect blood samples for biochemical analysis and record the general body position measurement, blood pressure, blood lipid, blood sugar and other related changes of the subjects, and monitor the liver, kidney, and thyroid functions.
