    Abstract Several different reactive oxygen species (ROS) are generated in vivo. They have roles in the development of certain human diseases whilst also performing physiological functions. ROS are counterbalanced by an antioxidant defence network, which functions to modulate ROS levels to allow their physiological roles whilst minimizing the oxidative damage they cause that can contribute to disease development. This Review describes the mechanisms of action of antioxidants synthesized in vivo, antioxidants derived from the human diet and synthetic antioxidants developed as therapeutic agents, with a focus on the gaps in our current knowledge and the approaches needed to close them. The Review also explores the reasons behind the successes and failures of antioxidants in treating or preventing human disease. Antioxidants may have special roles in the gastrointestinal tract, and many lifestyle features known to promote health (especially diet, exercise and the control of blood glucose and cholesterol levels) may be acting, at least in part, by antioxidant mechanisms. Certain reactive sulfur species may be important antioxidants but more accurate determinations of their concentrations in vivo are needed to help assess their contributions.

    Abstract The field of oxygen free radicals, antioxidants and reactive oxygen species (ROS) has exploded in the past few decades, and BBRC has published several seminal papers. ROS can cause oxidative damage, but also play fundamental roles in living organisms, in such processes as signal transduction and defence against pathogens. ROS underpin every aspect of human biology. Indeed, an endless stream of published papers refers to the biological roles of "ROS". Sadly, much of this work is mechanistically meaningless. To make progress, the detailed molecular mechanisms of action of ROS must be elucidated and appropriate methodology must be used to measure them and the oxidative damage that they can cause, as emphasized in a recent review by Murphy et al. Attention must also switch from clinical studies involving administration of high-dose supplements of vitamins E, C and β-carotene for the treatment or prevention of human disease into other promising diet-derived cytoprotective agents. One of them may be ergothioneine.

    Abstract We propose that the diet-derived compound ergothioneine (ET) is an important nutrient in the human body, especially for maintenance of normal brain function, and that low body ET levels predispose humans to significantly increased risks of neurodegenerative (cognitive impairment, dementia, Parkinson's disease) and possibly other age-related diseases (including frailty, cardiovascular disease, and eye disease). Hence, restoring ET levels in the body could assist in mitigating these risks, which are rapidly increasing due to ageing populations globally. Prevention of neurodegeneration is especially important, since by the time dementia is usually diagnosed damage to the brain is extensive and likely irreversible. ET and vitamin E from the diet may act in parallel or even synergistically to protect different parts of the brain; both may be "neuroprotective vitamins". The present article reviews the substantial scientific basis supporting these proposals about the role of ET.
