Dietary Supplementation and Immune System Study

This study is looking at how a dietary supplement, Monosaccharide Powder, affects your immune system, specifically how it changes certain proteins (Immunoglobulin fragment crystallization modifications) in your blood. You would be randomly assigned to receive either the Monosaccharide Powder or a placebo (a sugar powder that looks the same but has no active ingredient). Researchers will be looking for changes in these proteins after 4 weeks. This study is for healthy adults between 18 and 45 years old with a healthy body mass index (BMI). The current recruitment status is unclear.

Study design
This is a randomized, double-blind, placebo-controlled study involving 44 healthy adults.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
Your Immunoglobulin fragment crystallization modifications will be measured at 4 weeks.
