Effect of chromium niacinate and chromium picolinate supplementation on plasma lipid peroxidation levels in STZ-treated diabetic rats. Values are Mean±SE. C, control; D, diabetic, D+CrN: Cr-N-treated D; D+Cr-P, Cr-P-treated diabetic rats. Rats were supplemented with control-buffer, Cr-N (400 µg Cr/kg BW) or Cr-P (400 µg Cr/Kg BW) by gavages daily for 7 wks. Differences between values marked * versus** (p<0.02), **versus# (p<0.02), **versus## (p<0.02) are significant.
