In brief: Cod liver oil OK

There are 5 main groups of seafood: bony fish (cod), crustaceans (shrimp), bivalves (clam), cephalopods (squid), gastropods (squid).
There is cross-reactivity within each group but rarely between groups, so cod is ok with shellfish allergy. Probiotics are healthy but have minimal effect on mouth fungus (thrush). Most experts feel stomach fungal/yeast overgrowth doesn't exist.

In brief: Several questions

1. Cod liver oil, if you can tolerate it, is ok to take, even with a shellfish allergy 2.
Probiotics are usually strains of lactobacillus species which may help to repopulate a GI tract flora altered by antibiotic treatment, and can be beneficial.

3. Yeast seldom if ever overgrows in the stomach. How did you decide this was occurring? 4. If you have yeast on your tongue you may want to have your immune status checked and have an HIV test.
