Calcium is a very important nutrient and as such, it is very important that all humans consume sufficient amounts. However, some calcium supplements have been known to contain small quantities of lead. This research project used a retrospective approach to explore the trade-off between the benefits of calcium vs. the potential lead exposure amongst people who are taking these supplements. A survey consisting of 10 questions was used to try to assess the rate of consumption of specific types of calcium supplements. This research project obtained lead levels in calcium supplements from previous research and applied that data into this research project using the assumption that the levels were consistent to currents levels of lead in calcium supplements. The Mann-Whitney and Chi-Square tests were used to analyze the data, since it was determined that the continuous variables in the data were non-normal and the other variables were categorical. Significance was determined for α<.05. It was found that women consume more milligrams of calcium per day when compared to men and they also as have a higher exposure to lead as a result. The research also found that there is a positive association between age and the length of time a person has been consuming calcium supplements.
