Component

Beetroot juice and whole beetroot in the 2017 pharmacokinetic study

250 mL juice or 300 g whole beetroot in a human crossover study; not isolated betanin.

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 it acts on

  1. Plasma NOx remained elevated for 8 h after beetroot juice and 5 h after whole beetroot despite undetectable plasma betanin.

    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. Mixed-food nitrate-related observation; not a claim that betalains generate NO or mediate nitrate-associated performance effects.
