Branched-chain amino acid (BCAA) supplements have mainly been administered as a nutritional intervention for decompensated liver cirrhosis. Several studies have shown that short-term BCAA supplementation improves insulin and glucose tolerance in patients with liver cirrhosis. However, the long-term effects of BCAA supplementation on glucose tolerance and in patients with nonalcoholic steatohepatitis (NASH)-related liver cirrhosis are unknown. Herein, we report 2 cases of NASH-related liver cirrhosis in which long-term BCAA supplementation improved glycemic control. We conclude that in the absence of an effective conventional therapy for NASH-related liver cirrhosis, BCAA supplementation should be considered as an alternative treatment.
