Ferulic acid (FA) belongs to the family of phenolic acids and is very abundant in fruits and vegetables. Over the past years, several studies have shown that FA acts as a potent antioxidant by scavenging free radicals and enhancing the cell stress response through the up-regulation of cytoprotective systems, e.g. heme oxygenase-1, heat shock protein 70, extracellular signal-regulated kinase 1/2 and the proto-oncogene Akt. Furthermore, FA was shown to inhibit the expression and/or activity of cytotoxic enzymes, including inducible nitric oxide synthase, caspases and cyclooxygenase-2. Based on this evidence, FA has been proposed as a potential treatment for many disorders including Alzheimer’s disease, cancer, cardiovascular diseases, diabetes mellitus and skin disease. However, despite the great abundance of preclinical research, only a few studies were carried out in humans, the majority of which used …
