Frequently Asked Questions

If you are still unsure about this test, here are some questions that we usually get asked.

Still need answers?

Is the sun the main source of vitamin D?

While the body can produce vitamin D on its own when bare skin is exposed to sunlight, the majority of people can get enough from foods which have been fortified with Vitamin D and from supplements.

Does sunscreen affect the amount of vitamin D I get from the sun?

Studies have shown that even people who apply sunscreen to their skin every day still manage to maintain adequate levels of Vitamin D because the body naturally disposes of excess Vitamin D anyway.

Can a person have too much vitamin D?

It is possible to have too much vitamin D. This most commonly occurs when people take too many vitamin D supplements.
