Scivation's Xtend


Scivation's Xtend features an advanced endurance and recovery enhancer. It contains a precise blend of BCAAs (branched chain amino acids), glutamine, citrulline malate and vitamin B6. Research suggests that BCAAs can help athletes improve strength, endurance and recovery during training or performance.

BCAAs leucine, valine and isoleucine make up about 1/3 of muscle protein. Xtend delivers a 2:1:1 ratio of leucine to valine and to isoleucine, promoting muscle protein synthesis. BCAAs can be depleted from muscle when training, resulting in muscle loss and muscle breakdown (catabolism). Taking BCAAs supplies optimum muscle fuel to promote performance and reduce fatigue.
Vitamin B6 supports BCAA production and breakdown in the muscle tissue.

The conditionally essential amino acid glutamine helps prevent muscle tissue breakdown and support muscle repair. The amino acid citrulline is an NO precursor. NO is a natural pump that stimulates vasodilation (opens blood vessels) and increases blood flow to the brain and muscles. Citrulline can increase blood flow to muscle tissue and improve assimilation and absorption of protein.



Xtend is a powdered mix fortified with over 5 grams of BCAAs.

Xtend has the following benefits:

  • 2:1:1 ratio of BCAAs
  • Stimulates blood flow and improves protein absorption
  • Promotes muscle repair and recovery
  • Enhances endurance and muscle gain


Neurological side effects can occur with a vitamin B6 dosage higher than 200 mg.

Few side effects are associated with glutamine supplementation. However, mega-dosing with glutamine over an extended period of time may result in potential side effects such as diarrhea, weakness and nausea.

Pregnant or lactating women, people with pre-existing medical conditions or those taking medications should consult a physician before taking Xtend.
