A nutraceutical intervention for alleviating tired and heavy legs in healthy subjects: a randomized, double-blind, controlled study.
Article in BMC nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTired and heavy legs are common venous complaints associated with both lifestyle factors and chronic venous insufficiency (CVI).
methodsThis randomized, double-blind, placebo-controlled, study was conducted with 122 healthy subjects experiencing heavy and tired legs and telangiectasia. Participants received one tablet per day of a food supplement containing 570 mg of a formulated flavonoid complex (comprising 80% diosmin and a total flavonoid content of 90%) for 56 days. The control group included subjects with similar baseline characteristics, each receiving one tablet of placebo per day for the same duration. Assessment of leg discomfort, including sensations of heaviness and tiredness, as well as telangiectasia severity, skin color, and blood flow in the affected area, was conducted before (baseline or Day 0) and after 14 (D14), 28 (D28) and 56 (D56) days of supplementation. Additional evaluations included subjective perception of product effectiveness.
resultsBy D56, significant improvements were recorded: sensation of heavy legs decreased by 41.7% (p < 0.05), while the sensation of tired legs decreased by 45.2% (p < 0.01). The number of responders in the active group was approximately twice compared to the placebo group. Participants also reported a positive perception of the product's efficacy, and the treatment was well-tolerated.
conclusionsThese findings suggest that the tested food supplement provides beneficial effects in alleviating symptoms of heavy and tired legs.
