For fish-oil softgels, check both the source and the dosage form on the selected label. The Omega 3 Fish Oil Concentrate softgel listing is one explicit example.

A different oil supplied in a softgel is not automatically fish oil, and bottle count alone does not establish the same omega-3 content.View Omega 3 Fish Oil Concentrate – 2,000 MG (120 Softgels).
