Comparative bioavailability of β-carotene from raw carrots and fresh carrot juice in humans: a crossover study.
Article in Nutrition research and practice, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND/
objectivesCarrots are a major source of beta-carotene, but comparative studies on different consumption methods are limited. This study compared the rates of β-carotene absorption from fresh carrots versus fresh carrot juice. SUBJECTS/
methodsFor β-carotene absorption, a separate randomized controlled crossover trial was conducted with 16 healthy adults. The participants consumed 25 mg of β-carotene from raw carrots or fresh carrot juice. Blood samples were collected at the baseline (0 h) and at 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, and 24 h post-consumption.
resultsThe carrot juice group exhibited 2.33 times higher peak plasma concentrations 1.5 h post-consumption than those in the raw carrot group. The area under the curve for β-carotene absorption was 2.09 times greater in the carrot juice group than in the raw carrot group. The plasma α-carotene levels increased in both groups, but no significant differences were found. Similarly, no significant changes in the plasma levels of other fat-soluble vitamins were observed. In addition, no significant differences in antioxidant capacity (oxygen radical absorbance capacity and total radical-trapping antioxidant potential) were found between the 2 groups.
conclusionConsuming fresh carrot juice, without added sugars, may enhance the bioavailability of β-carotene compared to raw produce.
