From: Effects of L-carnitine supplementation on oxidative stress and antioxidant enzymes activities in patients with coronary artery disease: a randomized, placebo-controlled trial

  Placebo LC Pvalues2
  (n = 19) (n = 20)  
LC (μmol/L) -1.2 ± 20.0 (0.8) 7.6 ± 15.2 (7.2) 0.04
MDA (μmol/L) 0.1 ± 0.5 (0.0) -0.2 ± 0.5 (-0.1) 0.03
CAT (U/mg protein) -0.9 ± 3.4 (-1.0) 2.0 ± 6.9 (1.8) 0.02
SOD (U/mg protein) -1.9 ± 5.7 (-1.2) 5.9 ± 4.9 (6.8) < 0.01
GPx (U/mg protein) -1.4 ± 3.5 (-1.3) 2.7 ± 4.4 (2.4) < 0.01
  1. 1mean ± SD (median).
  2. 2values are significantly different between the placebo and LC groups.
