How much vitamin D is in Green Pasture cod liver oil?Our cod liver oil is not made in large factories. It is batch brewed so each batch can have slightly different levels of vitamin D.
It's important to note that vitamin D levels can vary between labs and even between tests. We're not sure how much faith we have in current vitamin D tests.
The level that we usually quote is ~750IU/ml. To see the latest testing results on our cod liver oil see here
