If that is the only cod liver source you can get, then its fine. Just don't ever get rancid or fermented cod liver oil/ Sometimes I supplement with Emu oil, pure red Palm oil from West Africa with a mix of coconut oil and or edible shea butter. This supplies my body with healthy fats of Vitamin A and D and other good ones.
If I get Cod liver oil I get mine from Nordic naturals or Rosita Extra version Cod live roil. Good wild and raw brands.
