There is a store called Natures Way in Spanish Town. I haven't actually visited there but did go to their sister store in East End, Tortola where they were extremely helpful. Lots of gluten free products, which is what I need, so didn't look further. They have a website, so do a simple search and it should come up. If you let them know know well in advance (three weeks+.) I am sure they can arrange most everything you need. Good luck.
