Simply Orange [probably pricey] has a version with calcium & vitamin D - 3mcg per 8 oz glass (you're probably sticking with the 4 oz glass because of the sugar?).

A 1000 IU D₃ supplement is 25mcg - (40 IU per mcg).

This puts the Simply Orange fortified 4 oz glass at 60 IU [1.5mcg].

Another thing about vitamin D supplements - taken with fat, it increases the absorption of D₃.

I always try to take mine with my heavy cream, eggs or bacon.

in part, but also interestingly if you drink 4 oz of OJ, it counts as a fruit exchange, but if you drink 8 oz, it is dairy.

Hey, I don’t make up the exchange stuff, someone else does. :)
