Component

Human plasma betanin exposure

2 recorded relationships. Experimental role, claim status and evidence remain attached to each record.

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. Betanin was undetectable at all sampled plasma time points after beetroot juice or whole beetroot in this crossover study.

    Experimental context and source evidence
    dose
    250 mL beetroot juice or 300 g whole beetroot versus placebo
    duration
    Baseline and 1, 2, 3, 5 and 8 h
    evidence_access
    Primary PubMed abstract; detailed exposure for PMID 23931157 additionally checked in publisher results. No uninspected full text is claimed.
    evidence_scope
    literature_reviewed; source-derived curation, not universally established human effects
    experimental_model
    Ten healthy men in a randomized crossover study
    limitations
    An undetectable parent compound is not proof of zero absorption. Food matrix, degradation and analytical methods differ from the cactus pear study. NOx is not itself a measurement of a betanin mechanism.

  2. After cactus pear ingestion, plasma betanin peaked at 3 h and was undetectable by 12 h.

    Experimental context and source evidence
    dose
    Single 500 g cactus pear pulp meal: 28 mg indicaxanthin and 16 mg betanin

    limitations
    Whole-food exposure cannot attribute the LDL response exclusively to either pigment; urinary recovery is not absolute absorption.
