Answer:

Yes. In fact, vitamin D is best absorbed when taken with a meal containing fats or oils, so fish oil can only help with that. Absorption of the omega-3 fatty acids in fish oil won't be affected by the vitamin D.

See the "What to Consider When Using" section of each Review for more tips for taking vitamin D and fish oil.
