Special Issue Information
Dear Colleagues,
Dietary antioxidants are a widespread family of molecules characterized by their chemical structure (e.g., phenols, vitamins, peptides, etc.), chemical–physical properties (e.g., lipophilic or hydrophilic), and activity (enzymatic or nonenzymatic). They mitigate oxidative stress due to excessive and uncontrolled reactive oxygen species (ROS; i.e., singlet oxygen, peroxynitrite, hydroxyl radical OH−, superoxide ion O2−, hydrogen peroxide H2O2) and free radical production. Exogenous (i.e., smoke, pollutants, and radiation) and endogenous factors (i.e., aerobic metabolism in mitochondria, enzymatic reactions, etc.) induce their production. Oxidative stress causes inflammation, cardiovascular diseases, neurodegenerative illnesses, asthma, senescence, cancer, and premature skin aging. Food's antioxidative capacity is determined by a range of compounds, some of which may not be identified after their metabolization. Depending on their concentration, specific antioxidants may lead to under- or overestimating antioxidant activity since they work synergistically. In recent years, the consumption of functional foods and food supplements containing food antioxidants has expanded exponentially. Recently, supplements based on single antioxidants and extracts containing food antioxidants have been formulated. Unfortunately, many antioxidants act as prooxidants at high concentrations, increasing to oxidative stress and inducing toxicity. This Special Issue aims to collect reviews and research articles in which dietary antioxidants' isolation, characterization, uses, delivery systems and toxicological aspects are reported.

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. Antioxidants is an international peer-reviewed open access monthly 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.
