Could cod liver oil tablets actually work?

Tablets vs capsules?: capsules or liquid are certainly a lot more common but sure, the EPA/DHA, Vits A and D can be packaged into a tablet as well. or do you mean does cod liver oil work, period? it is certainly considered one of the more helpful supplements - supplying things people are actually often short on (see above). anything that dates back 2000+ years is good in my book, too!
