Survey of dietary supplementation showing high usage, and greater use by more highly educated people.
The survey covered 200 children whose parents were employees of a research center in Egypt, showing 50% prevalence of supplementation during the COVID-19 lockdown period. The most frequently used supplements were vitamin C, zinc, and vitamin D.
Supplementation was highest for parents with post-graduate degrees (79%), and the most common source of advice was physicians (71%). Authors caution that some parents were unfamiliar with potential harm from excessive supplementation.
