I tried that. It didn't work.  I used to eat tons of shrimp, but that didn't get the job done. Besides, I'm allergic to shrimp now.  I average about 3000-5000 IU daily of D-3.  I don't know of many foods that have that much Vitamin D-3.

Theres also the origin of the vitamin d in the softgels you're consuming, & its bio availability, wouldnt touch those things with a pole ... bleh

Looks like I am overeating the herring if 1oz is the normal serving size . You were looking Vitamin D content of 1oz serving size. Change it to 1 fillet 184g. 1 Fillet has 3000IU make it a whole herring you get 6000IU add liver and you might get a lot more I think. Let me know if I was wrong.

I have been eating herring fillets. Is it bad to eat herring a day ?

    I tried at the WF fish counter by me yesterday.  They didn't have it.  Maybe I'll try the fish area a farmer's market.  I don't think there are any fish mongers around here (you can tell I don't live on the water).  I know a place to get salted herrings (certainly not an Inuit type food) around here, but I did try one and it had kind of a rotten taste that I suppose people who eat mostly cooked fish can't taste.  Herring must come from Europe and in the US you'd probably have to be in NY to get it somewhat fresh.
