Omega-3 Fatty Acids Calculator

The Omega-3 Fatty Acids Calculator is an interactive research tool that reports national estimates for ingredients in Omega-3 Fatty Acids dietary supplements based on the 2015 national study.

This calculator allows you to enter ingredient information from labels and generate the appropriate predicted mean values, standard errors (SE) and 95% confidence intervals (CI) for those labeled levels.
