XL Whey+ contains a blend of the two most popular whey proteins: Whey Protein Concentrate (WPC) and Whey Protein Isolate (WPI). Each of these ingredients elicits their own unique health benefits, and combined together form a formidable sport supplement ingredient.

Whey Protein Concentrate is derived from cow’s milk and is produced as a by-product of cheese making (which the curds part of the “curd and whey” mix ia used for cheese). This ingredient has not only a high BCAA and glutamine content, essential for muscle growth and repair, but also a large amount of micronutrients contained within its protein fractions which give WPC its health boosting benefits. These includes health benefits such as improved gastrointestinal health, improved immune function, and some have even suggested it as an aid in cancer (Bounous, Batist & Gold, 1991).

Whey Protein Isolate is a form of whey protein which has been further processed to remove fats and sugars, thus giving a high % protein content. XL Whey+ uses a blend of these two protein forms to give not only a market leading high protein % but also includes the added benefits that WPC offers.

In addition to this, XL Whey+ also contains the prebiotic Fructooligosaccharide (FOS), which acts as a fuel source for intestinal bacteria to provide an optimal environment for both digestion and growth. FOS has also been shown to increase calcium (van denHeuvel et al, 1999) and magnesium (Ohta et al, 1996) absorption in the gut.

Whey Protein has been known in the exercise community for many years to help increase muscular growth and repair, and a recently a study has highlighted whey protein when combined with resistance exercise to directly activate the mTOR pathway; the pathway linked inextricably to muscular growth (Hulmi et al, 2009). The benefits of whey protein are not just confined to those trying to grow muscle; whey protein also helps to curb ones appetite by decreasing hunger signals (Hall et al, 2003), therefore being a useful aid to anyone on a calorie restricted diet.

It is recommend that XL Whey+ be taken at times where it is hard to consume a large amount of protein, such as at breakfast and at night; to take it to boost the protein content of meals that are generally low in protein; or finally as a post workout supplement (however we strongly recommend XL Synthesis over this).
