Dr Juliet Pullar is currently involved in undertaking human studies investigating the bioavailability of vitamin C and its role in health and disease.
Two human studies have been completed on the bioavailability of vitamin C from kiwifruit, demonstrating the intakes required in those with low vitamin C levels to obtain ‘healthy’ or ‘optimal’ vitamin C status. She has also compared the relative bioavailability of vitamin C in kiwifruit to a supplemental source and shown effects on skeletal muscle levels and subjective mood.
A recent vitamin C study delved into the effects of vitamin C on male fertility and also neutrophil function, and it is in these areas that further in vitro work is planned by Dr Pullar.
She is also interested in population health and is currently investigating vitamin C levels in young male students within the Christchurch population.
