People with sufficient vitamin D levels likely take supplements along with other vitamins so it may be that it's not just vitamin D, but it in combination with other vitamins. If this study just gave people vitamin D supplements and nothing else then it may be that it didn't have needed "supporting vitamins".

So lifestyle factors other than eating play a large role, like time outdoors, and how far north one lives.
