Can You Take Fish Oil and Vitamin D Together?
Quick Answer
Yes, and it's actually ideal. Vitamin D is fat-soluble, so it absorbs better with fat. Fish oil provides that fat. Taking them together is more convenient and may improve vitamin D absorption. Many combination products exist for this reason.
Key Points
- Completely safe together
- Fish oil fat helps vitamin D absorb
- No negative interactions
- Many combo products exist
- Take with food for best absorption
