Plant milks with iodine?

I recently realized that I'm not sure if I'm getting enough iodine in my diet (I cook with Himalayan salt which isn't fortified and my current multivitamin only has 50% of my RDA). Google keeps telling me that fortified plant milks are a great vegan source of iodine, but I've been reading labels at the grocery store and I can't find any plant milks with iodine. Do they actually exist, and if so, which brands do you use? I'm in the US for reference.
