Hematogen, or gematogen, is a Soviet-era supplement notorious for containing at least 5 percent black food albumin, a technical term for cow’s blood.
In the Soviet Union, even sweet treats had a practical purpose. In the case of Hematogen, its controversial secret ingredient helped consumers treat anemia, malnutrition, and fatigue. It was consumed by both children and adults, who loved both its sweet vanilla flavor and the effect it had on their health and overall food. Once only sold to the public in pharmacies, Hematogen can now be found in a variety of stores and shops in ex-Soviet countries like Russia and Ukraine, and even as far as the US and Canada. You can even order them on Amazon.
