Summary

This study looks at how tartaric acid, a natural compound in wine, grapes, and grape juice, is absorbed and processed by the body. Thirty healthy, non-smoking adults aged 20-40 will consume each food source separately, then provide blood and urine samples over 24 hours. The goal is to see if the food matrix affects how much tartaric acid enters the bloodstream. This is an observational study, not a treatment for any disease.
