Effects of Athletic Nutritional Supplements on the Human Gut Microbiota: A Narrative Review.
Review in Nutrients, 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
The human gut microbiota constitutes the microbial ecosystem within the human gut. It consists of trillions of mostly prokaryotic microorganisms living in the gut lumen, which have an active metabolic role in the regulation of many host functions, including vitamin synthesis and energy extraction from indigestible fiber. Host diet is the main driver of gut microbial composition and metabolic output. Athletes and athletic individuals often supplement their diet with legal nutritional supplements to enhance performance, especially at the elite level. This review summarizes and critically comments on key evidence of the effects of the most common athletic nutritional supplements on the human gut microbiota, based on the most recent literature. We cover suggested changes in bacterial diversity or the relative abundance of specific bacterial taxa and effects of nutritional supplementation on bacterial metabolism. We focus on the molecular pathways involved, we discuss contrasting results and inconsistencies, and we note limitations and challenges in the field. We conclude with a summary of evidence, proposals, and future directions.
