Drinking anything other than water while your aligners are in, even through a straw, will most likely damage the aligners and is not recommended. Dark-colored beverages may stain the aligners, and hot beverages could damage or warp the plastic.  However, Invisalign aligners are easily removed so you can enjoy your favorite foods and beverages. Just be sure to keep track of your aligner when it’s out, and rinse your mouth or brush your teeth if possible before replacing the aligner.
