Recovery of orally administered C3G-derived isotope in human urine and breath

Recovery of orally administered C3G-derived isotope in human urine and breath. Interpret through the linked experimental species, preparation, compartment and exposure; no universal causal effect is implied.

How nutrients influence it

Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.

How nutrients reach it in more than one step

Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What acts on it

  1. After 500 mg labeled C3G in eight men, urine plus breath contained 12.38% of administered label over 48 hours; this is not intact C3G recovery.

    **Tracer recovery is not intact-pigment bioavailability.** Eight men received 500 mg of isotopically labeled cyanidin-3-glucoside (C3G), with sampling over 48 hours. The reported 12.38 ± 1.38% relative bioavailability comprised labeled carbon recovered in urine and breath: 5.37 ± 0.67% and 6.91 ± 1.59%, respectively. It is not 12.38% intact C3G, nor 12.38% pharmacologically active material. Combined labeled serum metabolites peaked at approximately 5.97 µM around 10.25 hours. Low urinary recovery of unchanged pigment cannot quantify total absorption. [Czank et al., 2013](https://pubmed.ncbi.nlm.nih.gov/23604435/).
