- 7g of BCAAs
- 2:1:1 Ratio
- Also Contains Glutamine, Citrulline Malate and added Electrolytes
Xtend Free from Scivation contains the same formula as Xtend, however, contains only all natural flavors, colors, and sweeteners and is the perfect solution for those looking to avoid certain ingredients while still getting the same benefits of Xtend BCAAs.
Just like Xtend, Xtend Free comes with 7g of BCAAs in the same 2:1:1 ratio along with Glutamine and Citrulline Malate, Plus, a proprietary blend of hydration-promoting electrolytes,
Scivation Xtend contains 7g of branched-chain amino acids per serving. Each serving of Scivation Xtend contains 3.5 grams of Leucine to stimulate muscle protein synthesis plus 1.75 grams of Valine and 1.75 grams of Isoleucine.
Some amino formulas drop the amounts of Valine and Isoleucine in favor or Leucine
However, Valine and Isoleucine also have very important benefits. For one, Valine competes with Tryptophan for uptake into the brain, and a brain soaked in Tryptophan will have a much hard time relaying the message to the muscles that they need to work harder and push more weight. Furthermore, in a Japanese study, scientists observed a fat-burning mechanism dependent upon Isoleucine. Subjects who consumed more supplemental Isoleucine gained less body fat than those who did not, even though both groups ate a high-fat diet.
