A single serving (3.5 oz) of wild-caught salmon has 988 ± 524 IU of vitamin D3, an amount that remains unchanged after baking but that decreases by 50% if the salmon is fried in vegetable oil. [74] In comparison, farm-raised salmon has only 25% of the vitamin D3 content found in the flesh of wild salmon. Blue fish and mackerel have vitamin D3 levels of 280 ± 68 IU and 24 IU, respectively. [74]

Fortified milk may contain less than the stated amount of vitamin D3 on the product (in some cases less than 80% of the amount). [75] Vegetables are not a good source for vitamin D.
