Alpha lipoic acid (ALA) acts as an antioxidant that seeks out free radicals, those pesky molecules that cause oxidative stress to our cells. And our energy levels depend on healthy cells, so antioxidants like ALA play a big role in energy metabolism. Our bodies make ALA, but not a lot of it, so adding an ALA supplement to the diet may add health benefits. More good news on ALA: Some studies suggest that alpha-lipoic acid might help control blood sugar levels and reduce inflammation, too.
