Chromium supplementation may be good for the heart in people with type 2 diabetes, according to study findings. It appears to lead to a shortening of a harmful heart rhythm, which may lower cardiovascular risk in type 2 diabetics.
Researchers also note in the American Heart Journal that blood insulin levels decreased significantly after 3 months of chromium supplementation and this may be partly responsible for the QT interval (heart rhythm) shortening.
A prolonged QT interval has been associated with high blood sugar levels, high insulin levels and reduced sensitivity to insulin in type 2 diabetics, they explain. Chromium supplementation improves sensitivity to insulin, lowers blood insulin levels and improves glucose homeostasis.
