Because cod liver oil contains quite a bit of vitamins D and A, it is also possible that side effects can occur due to toxicities from either of these vitamins. There is some concern that long-term use of cod liver oil could increase the risk of skin cancer.
A popular objection to eating liver is the belief that the liver is a storage organ for toxins in the body. While it is true that one of the liverâs role is to neutralize toxins (such as drugs, chemical agents and poisons), it does not store these toxins.peaking of vitamin A: I have learned that cod liver oil and liver itself are both high in vitamin A, so much so that it seems that you can easily overdose and end up with vitamin A toxicity (details on Wikipedia etc.) so caution is advised. Perhaps best not to take both for any extended period of time.
