Of course its synthetic. Its thiamine monitrate, a lab created form of thiamine that's also used to fortify white flour. It's used in food fortification because it has a much better tolerance for heat than the more natural form of thiamine, thiamine hcl, and it's used in supplements like this liquid because it's much more palatable than thiamine hcl, but it is also much less absorbed than thiamine hcl. The only completely natural form of any nutrient is going to be found in food or in a whole food supplement with no added vitamins. In nature only bacteria and plants synthesize vitamins, and minerals that are absorbed by plants and leached into our water sources come from the ground. Any other source of them is technically "synthetic."
