This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.

What is this trial?

This trial is testing RSB11-HI, a postbiotic supplement made from beneficial bacteria, to see if it can help healthy adults manage their weight and support metabolic health. A postbiotic is a substance produced by good bacteria that may have health benefits. Researchers will compare the medication to a placebo (a dummy pill) over 8 weeks to understand whether it actually works and is safe.

Many people struggle with weight management and metabolic wellness, and researchers want to explore new natural approaches that might help. This medication is being tested because early research suggests it could support these health goals, but it needs rigorous testing to confirm whether it truly makes a difference in real people.

Do you qualify?

You likely qualify if…

you are between 18 and 55 years old
you have a BMI between 23 and 32 kg/m² (your doctor can tell you your BMI)
you are in generally good health with no major gastrointestinal or metabolic conditions
you have reliable internet access and can complete study activities remotely on a smartphone, tablet, or computer
you are willing to keep your eating and exercise habits the same during the study and not start new weight-loss programs or supplements

You likely don't qualify if…

you are pregnant, planning to become pregnant during the study, or breastfeeding
you are currently taking prescription medications for weight loss
you have taken antibiotics in the past 4 weeks or are using probiotic or postbiotic supplements you cannot stop 4 weeks before starting
you have a history of significant digestive problems or metabolic disorders that your doctor thinks could interfere with the study
you are currently enrolled in another clinical trial or have been in one within the past 30 days

What participation looks like

If you join this study, you'll take either the postbiotic supplement or a placebo pill once daily for 8 weeks — neither you nor the researchers will know which one you're receiving until the study ends. You'll complete regular check-ins and assessments online using your computer or phone, answer questions about your weight, energy, digestion, and overall quality of life, and maintain your normal diet and exercise routine. The study is designed to be convenient, with most activities done from home.
