Anitra conducts a variety of studies, including observational, pharmacokinetic, and randomised controlled trials. She has produced a number of high impact publications that have helped inform international guidelines around recommended dietary intakes for vitamin C.

Anitra obtained her PhD from the University of Otago, Christchurch, followed by an American Heart Association Postdoctoral Fellowship, carried out at the Linus Pauling Institute, Oregon State University, USA, culminating in promotion to Assistant Professor.
