Alpha Lipoic Sustain® with its revolutionary Sustain™ bilayer Quick Release/Sustained Release format ensures maximum and sustained blood levels. This unique feature also minimizes gastric irritation and blood sugar fluctuations.* Alpha Lipoic Acid is an antioxidant that not only helps in glucose metabolism and energy production, but also encourages the synthesis of glutathione to create a strong antioxidant defense system in the body.* Biotin is also included to make sure ALA works optimally.*

The advanced bilayer Sustain™ tablets combine 1/3 Quick Release and 2/3 Sustained Release formats to both immediately raise and to maintain blood levels over a longer period of time.
