The prevalence of nutritional supplement usage in relation to dietary intake of vitamins and minerals was studied in a group of 130 elderly at the age of 75-80 years living in a small town near Warsaw.
Dietary data were based on a 3-day food record.
The use of vitamin/mineral supplements during the preceding year was reported by 43.8% of respondents, more often by women, persons with chronic diseases and users of medicines other than men, persons without chronic diseases and non-users of medicines.
Vitamin C was the supplement most commonly taken (63.1% of users), followed by thiamin, riboflavin and pyridoxine.
Supplement users did not differ from non-users in terms of intake from diet alone, for any nutrient compared.
The percentage of supplement users in the subgroup with dietary intake of specific nutrients lower than 67% of Recommended Dietary Allowances and in the subgroup with higher dietary intake was similar.
Minerals were often used in the doses not sufficient to eliminate the risk of deficiency while vitamins were often taken in amounts much higher than RDA's.
