Cod Liver Oil

How does Cod Liver Oil work?

Cod liver oil contains certain "fatty acids" that prevent the blood from clotting easily. These fatty acids also reduce pain and swelling.

Are there safety concerns?

Cod liver oil is safe for most people. It can cause side effects including belching, bad breath, heartburn, and nosebleeds. Taking cod liver oil with meals can often decrease these side effects.

High doses might keep blood from clotting and can increase the chance of bleeding. Vitamin A and vitamin D levels might also become too high with high doses of cod liver oil. High doses might also cause nausea and loose stools.

Do not take cod liver oil if:
  • You are pregnant or breast-feeding.
  • You are sensitive to aspirin. Cod liver oil might affect your breathing.
