How long do nutrients stay in your system?

The duration that nutrients stay in your system varies based on the type of nutrient and individual metabolism. Generally, carbohydrates can be utilized within hours, while proteins may take a few hours to days to be fully digested and absorbed. Fats can linger longer, with some components remaining in the body for days or even weeks. Additionally, factors like diet, activity level, and hydration can influence nutrient retention time.
