PhD Nutrition Introduces GlycoDurance® with Sustamine® L-Alanyl-L-Glutamine

Training and Race Formula Ideally Suited for Sustained Energy*  

PhD Nutrition has created GlycoDurance® an innovative training and race fuel with the lowest serum osmolarity in the industry.

GlycoDurance contains three key elements; a scientific blend of electrolytes; Sustamine® L-Alanyl-L-Glutamine to quickly release glucose into the bloodstream and boost the body’s recovery time; and Cluster Dextrin®, which passes through the stomach faster than any other carbohydrate source. That means a quick but sustained release of glucose into the bloodstream.

Sustamine® works to enhance the absorption of electrolytes in the powder blend, as well as improve water absorption in the intestines while also stimulating glycogen production.* Muscles must be hydrated and engorged with glycogen to perform at their peak and when it’s all over, the body needs to recover. That’s where Sustamine® comes in. Glutamine, the key component of Sustamine® is the most abundant single amino acid in the body, and it’s considered conditionally essential during times when the body undergoes large amounts of stress – like during intense endurance events, training or dealing with the challenges of everyday life.*

About Sustamine 

Sustamine® L-Alanyl-L-Glutamine is a stable dipeptide of L-Alanine and L-Glutamine. Sustamine is more easily absorbed by the body than complex protein molecules. This makes Sustamine a highly effective ingredient for hydration, endurance and recovery.* Vegetarian, allergen-free and the only GRAS L-Alanyl-L-Glutamine, Sustamine is also tasteless, odorless, and stable in liquids.

Sustamine is an ingredient that works on multiple levels to help rehydrate the body and sustain energy levels during exertion. Sustamine combines L-Glutamine (the most important amino acid for stimulating muscle protein synthesis) and L-Arginine (an amino acid needed for rebuilding your body’s glycogen stores). Sustamine enhances performance and recovery in three primary ways. It helps:

  • Replace lost electrolytes and fluids
  • Repair damaged muscle proteins
  • Refill the body’s energy stores
