Vitamin D spray

A friend shared this link with me, http://products.mercola.com/vitamin-d-spray/.   Her naturopath recommended the spray to her.  It is saying a serving is 6000 UI which is 6 pumps and a small bottle is a month’s supply.  I just received mine in the mail.  I have been taking a sublingual pill in the past.  Prior to my surgery I had very low vitamin D and it was recommendedthat I continue to take and my levels have thus far been good.

I've actually used this spray and have a great vit D level.  I'm scheduled for surgery next week and have asked our nutritionist about continuing to use... she says it may give me trouble due to the sorbitol.
