Organic acids as enhancers of phytase activity: A brief discussion based on the available literature and personal research

Bruno S Vieira , Joao G Caramo


The objective of this study was to briefly review the current knowledge regarding the combination of phytases and organic acids in animal and human nutrition. Based on this, and supported by some personal research data, we concluded that some organic acids, such as citric acid, enhances phytase activity and promotes better growth performance and bone mineralization in phosphorus-restricted broilers. Further research is needed to better understand the rule of these additives in other species, including humans.
