Dried and powdered animal liver, typically from beef, used as a whole-food source of nutrients such as iron, copper, vitamin A, and B vitamins including B12.
Why it’s used
Taken as a concentrated source of naturally occurring nutrients, often marketed as a whole-food alternative to isolated vitamin and mineral supplements.
What the evidence says
The nutrient content of liver as a food is well documented, and individual nutrients it contains (such as B12, iron, and vitamin A) have established roles supported by NIH ODS fact sheets. However, desiccated liver as a supplement product has not itself been studied in clinical trials, so no direct evidence exists for benefits of the supplement form beyond the nutrients it happens to contain.
