A survey of the knowledge and use of dietary supplements by some population settlements in Zaria, Kaduna State, Nigeria
A survey was made to assess the knowledge and use of the dietary supplements by some people in the population settlements, Samaru, Palladan, Jama’a, Hayi Shehu, Kwangila, Sabon Gari and Grace land in Zaria, Kaduna State, Nigeria. About 219 respondents participated in this survey and 165 respondents reported they had prior knowledge of dietary supplements. The results in this survey revealed that since more than 15 years ago, there has been a growing awareness of the importance of and use of dietary supplements among the people in the population settlements where the survey was carried out. About 98 respondents (90 %) out of the 109 respondents who had prior knowledge of and used the dietary supplements before experienced remarkable improvement in their health. The adverse effect on health experienced by one of the 11 respondents who used the dietary supplements before but did not find them beneficial suggests that the quality and safety use of the dietary supplements in Nigeria should be properly monitored by the National Agency for Food and Drug Administration and Control ( NAFDAC). The widespread use of dietary supplements for the improvement of human health is feasible in Nigeria provided adequate education and professional guidance are made available to the general population on the appropriate and safety use of the dietary supplements to reduce the possible risk of adverse effects on health to potential users of dietary supplements.
