Study summary

The goal of this clinical trial is to learn the potential of bitter melon peptides in stabilizing blood glucose in diabetic adults. It will also learn about the effects of bitter melon peptides on metabolic parameters. The main questions it aims to answer are:

  • the regulatory effects of bitter melon peptides on glycemic variability
  • impact on glycemic and metabolic indicators Researchers will compare bitter melon peptides to a placebo (a look-alike capsule that contains Microcrystalline Cellulose) to see if bitter melon peptides works to stabilizing blood glucose.

Participants will:

  • Take bitter melon peptides or a placebo every day for 12 weeks
  • Visit the clinic on day 0, day 7, day 28 and day 84 for checkups and tests
  • Glucose levels were monitored continuously by CGMs in the first 7 days and fasting blood samples were drawn at first visit (day0), third visit (day 28) and fourth visits (day 84)

Study arms

  • Experimental
    bitter melon peptides

    Bitter melon peptide contains various active substances such as bitter melon saponins and bitter melon polysaccharides.

    Dietary Supplement: bitter melon peptides

  • Placebo comparator
    Placebo group

    The placebo capsule containing microcrystalline cellulose. The placebo is identical in appearance, color, and dosage schedule to the intervention product, but does not contain any active ingredients.

    Dietary Supplement: bitter melon peptides
