About Similac® Advance® Organic Ready-to-Feed and Similac® Advance®.
I called their customer care #: 1-800-850-7677 to ask if the Similac® Advance® contained any eggs derived ingredients or any ingredient derived from animal blood or flesh.
The good news is none is derived. However, the Vitamin D is
derived from Sheep Wool. The rep told me that sheep need not be slaughtered for
this.
