Alpha-Lipoic Acid for Insulin Resistance
B Good Evidence At least one randomized trial supports this, with mostly consistent results.Alpha-lipoic acid activates AMPK in multiple tissues. RCTs demonstrate improved insulin sensitivity in type 2 diabetics. It is approved in Germany for diabetic neuropathy at 600 mg/day. Both fat- and water-soluble, it reaches all tissue compartments.
The Bottom Line
Alpha-lipoic acid activates AMPK in multiple tissues. RCTs demonstrate improved insulin sensitivity in type 2 diabetics. It is approved in Germany for diabetic neuropathy at 600 mg/day. Both fat- and water-soluble, it reaches all tissue compartments.
