Cod Liver Oil vs Fish Oil?

I have a few questions about Cod Liver Oil softgels.

  1. Is it good quality?
  2. Are the vitamins added additionally or natural part of the oil?
  3. What is the recommended dosage?
  4. Is it better than standard fish oil?

Google Dr Rhonda Patrick fish oil. She has multiple podcasts (including with Joe Rogan speaking about different fish oil, brands and benefits)

Is eating fish once a twice a week a possibility?

To be honest I dont like fish especially the fatty ones and I want to take some fish oil supplement.
