Don't know. All I know is that I was the only kid among my cousins who liked cod liver oil. When I was a kid (lower primary school), my aunt would make all us cousins stand in line and fed a spoonful of Scott's Emulsion Cod Liver Oil after each dinner. Every kid other than me hated this part of our dinner, and some even tried to skip it by making themselves scarce - except moi! If my aunt didn't notice, I'd even go back to the back of the line for seconds! Everyone else hated it claiming it was fishy (or chao chor!), but I loved it!!!!
Later on in life, when cod live oil was available in capsules (I think the brand is Seven Seas), I'd bite into it to break the gelatin capsule so that the oil oozes out! Yum!
Cheers!
