Special Issue Information
Dear Colleagues,
Polyphenols are among the most extensively studied nutritional phytochemicals due to their potential beneficial effects on human health. Over recent years, significant advancements have deepened our understanding of their mechanisms of action, bioavailability, and interactions with biological systems. One particularly dynamic area of research is the dose-dependent activity of polyphenols and their complex interplay with gut microbiota, which significantly influences their metabolism and biological effects.
This Special Issue offers a comprehensive exploration of the intricate relationships between polyphenol dosage, their bioactivities, and their modulation of gut microbial communities. Moving beyond a narrow focus on individual polyphenol compounds or isolated health outcomes, this Issue aims to provide a broad perspective on current research. Topics of interest include, but are not limited to, the following:
- Dose–response effects of polyphenols on human health outcomes.
- Biotransformation of polyphenols by gut microbiota and its impact on bioactivity.
- Reciprocal interactions between polyphenols and gut microbial composition or functionality.
- Clinical and preclinical evidence of dose-specific polyphenol effects mediated by the gut microbiome.
- Methodological advances for studying dose-dependent polyphenol–microbiota interactions.
By highlighting the synergistic and dose-specific effects of polyphenols in the context of gut microbiota, this Issue seeks to expand our understanding of their role in human health and encourage innovative research at the intersection of nutrition, microbiology, and pharmacology.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nutrients is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
