The first ingredient of the essential recovery formula is Waxy Maize Starch (WMS). WMS supplies the carbohydrate within the blend, helping to refuel drained glycogen stores after a hard training session: the first essential step in the recovery process. WMS achieves this to a greater degree than any other carbohydrate due to its high molecular weight; it is drawn into the intestines for absorption, bypassing the stomach where most simple carbohydrates tend to sit after ingestion causing wind and bloating. It is via this action of rapid absorption that WMS helps restore glycogen and hence kick start the recovery process faster than glucose or any other carbohydrate alone (Stephens et al, 2008). Another added benefit of its high molecular weight is that WMS tends to draw other ingredients along with it through to the intestines thus increasing the efficacy and absorption of the other ingredients contained within XL Synthesis. The second ingredient of our essential recovery mix is Hydrolysed Whey Protein (HWP). HWP is a special, enzymatically treated form of Whey Protein which has had its large chain protein molecules broken down into smaller chains thus increasing their absorption and assimilation. This partial digestion increases the effectiveness of HWP over that of other proteins such as whey protein concentrate or isolate (Calbet & Holst, 2004). Protein is essential after a workout to deliver amino acids to the torn and damaged muscles from a hard workout to initiate the recovery process for their growth and repair. Due to its rapid delivery and assimilation of protein, HWP works in tandem with the fast delivery of WMS. The next ingredient is L-Leucine, an amino acid that belongs to a group of amino acids called Branched-Chain Amino Acids (BCAAs), which have been shown to increase exercise performance, recovery and protein synthesis (Matsumoto et al, 2009; Greer et al, 2007). Specifically, L-Leucine has been shown to be the amino acid that independently stimulates protein synthesis, the growth of new protein tissues (such as muscle tissue), via activation of the mTOR pathway, our body’s primary anabolic pathway (Dreyer et al, 2008). After exercise, with the ingestion of protein, this pathway is activated and L-leucine helps to increase the strength of the signalling channel to this mechanism, thus increasing protein synthesis even further (Norton & Layman, 2006). The final ingredient in our mix is Creatine Monohydrate. Creatine acts as a buffer for our cellular energy source: ATP. Whenever energy is required, ATP is broken down to ADP. Creatine monohydrate helps to maintain our cellular pool of creatine phosphate (Persky & Brazeau, 2001), which inturn helps to redux ADP back to ATP. The more creatine phosphate available; the greater the resynthesise of ATP. Due to this effect, creatine monohydrate has been shown to increase protein synthesis (Parise et al, 2001), strength (Dempsey, Mazzone, & Meurer, 2002) and muscle mass (Volek, 1999). The benefits of creatine are not just limited to the weights room; creatine has also been shown to increase cognitive performance (Rae et al, 2003). In summary, it can be seen that XL Synthesis contains the most research proven ingredients available for recovery and are blended in a precise ratio dependant on your bodyweight for even greater accuracy of dosing. We strongly believe that due to the ingredients contained with XL Synthesis, it is without doubt the greater recovery supplement available on the market today.
