KemTRACE® Chromium for Beef Carcass
KemTRACE® Chromium is a highly bioavailable, organic source of chromium that helps improve glucose utilization for increased cellular energy and function. This results in better animal maintenance, growth and immunity.
KemTRACE Chromium is supported by more than 20 years of Kemin research and is the only U.S. Food and Drug Administration-reviewed form of chromium propionate.
Insulin plays a key role in optimum cell function by acting as a "key" in the lock to the door that allows glucose into the cell. Chromium supplementation primarily acts to improve insulin sensitivity, so more glucose can enter the cell. The additional glucose allows more energy to be available for proper cell function.
GLUT4 is the principle glucose transporter, responsible for facilitating the movement of glucose into the cell.1 A recent study found that longissimus muscle biopsies from cattle supplemented chromium propionate had an increase in internalized GLUT4s after a 147-day feeding period (Figure 1),2 which indicated these animals had more sufficient insulin sensitivity compared to the controls at day 147. The decrease of GLUT4 density on day 147 in the control animals have been an indication of decreased insulin sensitivity or insulin resistance occurring.

1. Insulin stimulates glucose uptake by cells.3
2. Readily available chromium from KemTRACE Chromium allows for increased glucose uptake by muscle cells through stabilization of the insulin receptor and subsequent upregulation of intracellular Glucose-4 transporters.
3. Greater glucose uptake by muscle cells increases protein synthesis.1
4. Increased protein synthesis may result in heavier carcass weight.1
