The Claim

In healthy adults aged 20–30, ingestion of 25 mg of β-carotene from either raw carrots or fresh carrot juice, consumed with 50 mL of canola oil, results in peak plasma β-carotene concentrations at 1.5 hours post-ingestion, with concentrations returning to baseline by 24 hours, indicating rapid absorption and clearance kinetics for both food forms.

In plain English

If young, healthy adults eat raw carrots or drink fresh carrot juice with a little canola oil, their bodies absorb the beta-carotene quickly—peaking in the blood in just 1.5 hours—and it’s all cleared out within 24 hours.

Consumption of 25 mg β-carotene from either raw carrots or fresh carrot juice with 50 mL of canola oil leads to peak plasma β-carotene concentrations at 1.5 hours post-ingestion in healthy adults aged 20–30, with levels returning to baseline by 24 hours, indicating rapid absorption and clearance kinetics for both forms.

What the research says

1 study
  1. Study: Comparative bioavailability of β-carotene from raw carrots and fresh carrot juice in humans: a crossover study

    The study found that carrot juice gives a much bigger boost in beta-carotene than raw carrots, and it doesn’t show that levels go back to normal by 24 hours for both, so the claim isn’t fully backed up.
