Cod Liver Oil 1,000 mg
Swanson EFAs Cod Liver Oil 1,000 mg is an 'Other Combinations' supplement, providing 1 gram of ecOmega Norwegian Cod Liver Oil per softgel, with a total of 5 ingredients. While cod liver oil is a known source of Vitamins A and D, this product's Vitamin A content at 114 mcg RAE (13% DV) and Vitamin D at 1 mcg (5% DV) are both significantly underdosed compared to common recommendations. The product received an N+ Score of 44, resulting in an 'F' grade, indicating a below-average quality assessment. This low score is largely attributed to the insufficient dosages of these key vitamins. It may be considered for general cod liver oil intake, but not for targeted vitamin A or D supplementation.
