If they came in pill form, then no, the opaque plastic would not be problematic. I prefer to avoid taking vast arrays of pills, though. I take iron because when I didn't I was so anemic that I ought to have been fainting on a daily basis, and I take vitamin D because my M.D. uncle said I should; that's all. But pills don't take up space that I use for enjoyable food. I love food! I don't want to replace it with displeasing things.
