MOST EXTREME LIPOIC SUPPLEMENT! R™ is the name of Syntrax's perfect alpha-lipoic acid supplement. While other companies in the industry use the cheaper RS form of alpha-lipoic acid, Syntrax has pushed the envelope to its extreme by releasing the R™ form of alpha-lipoic acid. R™ alpha-lipoic acid is the only totally natural form and demonstrates all of the beneficial properties of alpha-lipoic acid. Unfortunately, the RS form of alpha-lipoic acid is cheaper but it contains the non-natural form that has been shown in research studies to elicit some very serious negative consequences on insulin response/sensitivity. R-alpha lipoic acid is not only one of the very best and most universal antioxidants but it also is the perfect dietary supplement for improving insulin response/sensitivity and blood sugar control. Research studies have shown that the cheaper RS form of alpha-lipoic acid does not deliver the full beneficial effects of R form. If you are looking to fully control the destructive effects of glycation as well as obtain the anabolic and ergogenic effects of improved insulin response/sensitivity, then demand the R™ form of alpha-lipoic acid. With R™, you will notice almost immediately an improved sense of well-being. Furthermore, if you're an athlete of any type, you will notice a leaner, more fit body, fuller muscles and greater strength and performance. Demand the best; demand R™.
