With a history dating back to 6th-century China, seitan, a popular meat alternative, has acquired several names over its long history. Its chewy, fibrous texture has earned it monikers that range from descriptive to regional, making its identity a bit of a mystery for those new to plant-based diets.

In the world of acronyms, 'FU' is particularly ambiguous, with its interpretation depending entirely on the field of study. What do fu units stand for is not a single answer, but rather a context-dependent question that requires looking at the specific discipline, such as chemistry, plumbing, or environmental science.

According to a 2018 review in *Biomedical Reports*, nattokinase possesses potent fibrinolytic activity, and its dosage is commonly measured in Fibrinolytic Units (FU). The "FU" in nattokinase refers to Fibrinolytic Units, a standard measure of the enzyme's potency or its ability to break down fibrin, a protein involved in blood clot formation. Unlike standard weight measurements like milligrams (mg), FU quantifies the *activity* of the enzyme, ensuring consumers know its effectiveness regardless of physical mass.
