CSNs evidence-based and in-depth review on Scivation Xtend
Scivation Xtend is a Branched Chain Amino Acid (BCAA) supplement that was created to help support muscle growth, to keep the body in a positive protein balance when dieting, and to help boost performance in the gym. Xtend rapidly became, and still is, one of our top selling BCAA supplements as it has a reputation for great quality and great taste.
Claims and benefits made by Scivation about Xtend.
Scivation claim that Xtend is the most ‘advanced BCAA drink on the planet’ and contains a 2:1:1 ratio of the three BCAA’s, leucine, isoleucine and valine, which is the ratio found in nature and proven by research to be the most effective for supporting muscle growth.
Xtend is designed to support muscle growth, muscle hydration and to help maintain performance in, and recovery from, even the most gruelling training sessions. Xtend has been used by world-class fighters, professional bodybuilders and other elite athletes to help them train ‘harder, longer and with more intensity’.
Xtend was created to boost performance when taken as an intra-workout and its reported benefits come from ‘orchestrating optimal protein synthesis’ and ‘balancing intracellular energy economy’ helping to shorten recovery time. The quicker you recover, the more frequent and harder you can train and the quicker you get results.
Scivation Xtend ingredients
The backbone of Xtend is its 7g of BCAA’s in a research driven 2:1:1 ratio. This means that each serving of Xtend contains 3.5g of leucine, 1.75g of isoleucine and 1.75g of valine with 2.5g of the amino acid glutamine, which is the most abundant amino acid in the body.
It is leucine that has gotten the most attention in recent times due to its role in stimulating muscle protein synthesis (MPS). MPS is the process that allows the muscles to repair, boosting recovery and muscle growth (you can read all about MPS here). The addition of valine and isoleucine in the ratio found in Xtend is meant to simulate those found in other high-quality protein sources, and isoleucine, in particular, is an important amino acid for glucose and energy metabolism in muscle cells.
BCAA’s have also been suggested to help prevent fatigue by preventing a decline in circulating amino acid levels. A decline in amino acid levels can cause the release of hormones such as tryptophan, which induces feelings of fatigue and triggers reductions in performance.
Unlike many other BCAA supplements Xtend also contains key electrolytes which can become depleted during strenuous exercise and as they are important for maintaining cellular hydration and supporting efficient muscle function, these can also help maintain performance especially in intense, long-lasting exercise.
Finally, Xtend contains citrulline malate. Citrulline helps to increase nitric oxide (NO) levels in the blood. NO is an important cellular signaller that increases blood flow and has been linked to improvements in high intensity and endurance exercise. Citrulline malate’s usage with BCAA’s also has benefits as it enhances the uptake of amino acids into the muscles during exercise.
CSN's recommended dosage of Scivation Xtend
Xtend is suggested to be used as an intra-workout supplement to truly maximise its full recovery and performance boosting benefits. Simply take one or two scoops with around 300-500ml of water (or mix to taste) during exercise. For longer or more intense sessions, then two scoops would be recommended.
You can also use Xtend between meals, or if training in an unfed state, to help keep the body in a more positive amino acid balance and prevent muscle breakdown and boost recovery.
Can it be stacked with any other sports supplements?
If your goal is to build muscle, then Xtend goes well intra-workout with carbohydrate powders such as Vitargo or Highly branched Cyclic Dextrin. Using carbohydrate intra-workout will help support both performance and recovery, as well as muscle building processes.
BCAA’s also stack really well with creatine, beta-alanine and caffeine based supplements for those looking for that extra edge in terms of strength, performance and increased mental focus and intensity.
CSN's Summary of Scivation Xtend
Xtend is a research driven BCAA supplement that is designed to not only support recovery and muscle growth but also performance. Xtend combines high doses of BCAA’s in amounts that have been shown to stimulate muscle protein synthesis, an important driver of muscle growth.
The use of BCAAs help to keep the body in a positive amino acid balance, which may also help reduce exercise-induced fatigue and the inclusion of electrolytes and citrulline malate can help sustain performance.
Xtend is suitable for those who take part in strength, bodybuilding and endurance sports to help take their performance and recovery to the next level. The better we perform and the quicker we recover, the faster we are likely to see results.
