Hematogen



Hematogen (Гематоген) is a nutrition bar which is notable in that one of its main ingredients is black food albumin, a technical term for cow's blood. It was popular in the former Soviet Union. Other ingredients may vary, but they usually contain sugar, condensed milk and vanillin.

It is often considered to be a medicinal product, and is used to treat or prevent low blood levels of iron and vitamin B12 (e.g., for anemia or during pregnancy). In the Soviet Union, it was available over-the-counter.
