Overview

This double strength cod liver oil supplement provides a combination of omega-3 fatty acids (EPA and DHA), Vitamin A, and Vitamin D3. While these nutrients are generally beneficial, the specific combination and dosages require careful consideration. The presence of both Vitamin A and Cod Liver oil means this should probably not be stacked with other Vitamin A or D supplements to avoid overage.
