I just want to add, that some vitamins that I take, if they are huge like horsepills like multivitamins and calcium pills, I bring some, and buy them on the go in whichever country I'm at. Vitamins like D3, Fish Oil, Calcium, Milk Thistle, Multi, C, etc I've found in any country I've visited, including low strength aspirin. You can also stockup if you visit Brazil, by ordering from amazon brazil site or just go into the major stores with pharmacies or health food stores.
