Doctors said that alpha-lipoic acid is the “universal” antioxidant because it is both fat- and water-soluble, allowing it to protect a wider range of body systems. The researchers believe that alpha-lipoic acid helps shift glucose into muscles and away from fat cells, increasing energy and reducing stored fat.
In one study, scientists gave 1,127 overweight or obese men and women 800 mg of alpha-lipoic acid per day. After four months, average blood pressure had declined significantly. Participants also had an average of two to four points lower body mass index scores. Obese women lost an average of 3.5 inches in waist size, and obese men 4.3 inches.
