Chromium functions biologically as part of the organic complex known as glucose tolerance factor (GTF), which acts synergistically with insulin to promote cellular glucose uptake.

Compared to other chromium compounds, UltraChrome demonstrates the greatest effect on adipose cells, achieves the highest tissue levels throughout the body, and is most effective at facilitating glucose uptake on the cellular level. UltraChrome is a Thorne Research exclusive - it is available in 200 mcg and 500 mcg capsules.
