Abstract:

AIMS: Dietary supplement (DS) use is actively promoted among old people but there is little evidence in favour of DS use or information about the demographic, health and cognitive characteristics of DS users.

METHOD: We examined 176 healthy, old people without dementia all born in 1921 and living independently in the community. IQ scores aged about 11 years were available for all subjects. DS users were more often female, had a lower BMI and were taking fewer prescribed medications than non-users.

RESULTS: Usual dietary intake, as measured by food frequency questionnaire, did not differ between DS users and DS non-users. DS users were seen to have higher Vitamin C (p

CONCLUSIONS: DS users may enjoy somewhat better general health than non-users but the source of this difference is unknown. Possible health benefits of DS use merit further study.
