Bone marrow powder is a product made from sterilized bone marrow, the main component of which is fat, with very little protein and a small amount of calcium, as well as a small amount of trace elements. The main function of bone marrow powder is to provide a certain amount of unsaturated fatty acid supplement for patients with malnutrition, such as thinness, weakness of limbs, poor mental state, insomnia, forgetfulness and other symptoms.
