Okay, this is cut and pasted from a medical research journal, so it's very technical sounding but interesting! Basically they have preliminary findings that suggest the supplement carnitine (which is an amino acid) can help with the muscle pains people experience when on Accutane. Also it appears to help lower liver enzymes as well. This suggests that the carnitine is helpful in preventing possible liver damage by Accutane. Here it is...

ABSTRACT: BACKGROUND: Patients with cystic acne (CA) on Isotretinoin (Iso) therapy might present muscular symptoms as side effect of the drug. Myalgia, weakness, hypotension are also some of the main characteristics of carnitine (car) deficiency.

METHODS: Two hundred and thirty (N = 230) patients with CA were treated with Isotretinoin (0.5 mg/kg per 24 h). All the patients were requested to visit our out-patient department at the onset of muscular symptoms. Laboratory tests including car (total, free, acylcarnitine) were determined in blood and urine before treatment, at the onset of muscular symptoms and after the end of a 45 day study. Fifty percent of the patients with muscular involvement received L-carnitine (100 mg/kg per 24 h per os) (group C) and 50% placebo (group P).

RESULTS: Their laboratory tests showed the well known increases of their liver enzymes and lipids, whereas car blood levels were remarkably decreased at the onset of their muscular symptoms and or at the end of the study. Their supplementation with L-car, in patients of group C (N = 20) without Iso discontinuation or reduction, resulted in the disappearance of their muscular symptoms within 5-6 days and normalisation not only of the increased levels of their liver enzymes but also those of car, at the 45 day of their therapy. Additionally, the patients who received placebo (group P, N = 20) continued complaining for mualgias. The rest of the patients (group A, N = 190) did not experience any muscular symptoms, their laboratory tests showed elevation of liver enzymes and lipids and a decrease in car levels in the blood whereas a remarkable increase of car excretion was determined in their urine.

CONCLUSIONS: Iso therapy decreases car blood levels in patients with CA. L-car supplementation might treat liver and muscular side effects of the drug. These hopeful preliminary results need further investigation.
