Why Choose Whey Isolate Protein by XBrain?

Whatever your muscle goals may be, you need the right fuel to support you throughout your workouts. With so many protein formulas on the market, it’s tough to find one that you can trust and that will guarantee results. Whey Protein Isolate from XBrain is just that – a 100% natural, gluten-free, non-GMO formula without any fillers.

So often, whey protein products are laced with artificial sweeteners and fillers that have a negative impact on their quality. However, XBRAIN®WheyIsolate is leading the way with only the highest grade whey isolate protein.

It contains over 20.7g of protein per serving without taurine, glycine or any other fillers providing you with pure power for your workout allowing you to meet your muscle gain goals effectively and safely.

XBrain’s Whey Isolate Protein is made with high standards, incorporating the best technology throughout the process. Cross-flow microfiltration and cold processing produces a top quality, nutrient-enriched protein.

The milk used in developing XBrain’s leading Whey Isolate Protein formula is only sourced from grass-fed cows as opposed to feedlot cows meaning that the overall quality of the protein is enhanced making it the only choice to support your bodybuilding goals.


There are numerous health benefits associated with choosing a whey isolate protein derived from grass-fed cows’ milk:

  • Antibiotics
    When feedlot cows are treated with antibiotics, it can result in resistant bacteria making its way into the final protein formula. With grass-fed cows, this risk is eliminated and a healthier formula is made,
  • Growth Hormones
    Similarly, feedlot cows are given growth hormones which can be detrimental to their health. XBrain sources its milk from grass-fed cows so that it is of the highest quality and untainted by any unnatural additives.
  • Minerals
    Grass-fed cows produce milk with a significantly higher mineral content meaning that XBrain’s Whey Isolate Protein formula is strengthened with calcium, phosphorus, magnesium and potassium.
  • Amino Acids
    Branched-chain amino acids are more prominent in grass-fed cows’ milk and are essential for muscle growth.
  • Conjugated Linoleic Acid (CLA)
    Because XBrain sources their milk from grass-fed cows, it has a higher CLA content. CLA is a key ingredient as it helps defend your body against the risk of cancer, high blood pressure, high cholesterol, cardiovascular disease as well as inflammation, making it great for muscular recovery.
  • GMOs
    Whey Isolate Protein by XBrain uses high quality milk which is produced without pesticides or other chemicals that can be detrimental to human health making the protein formula clean and high grade.
  • Toxic Metals
    Other protein formulas are made with processes that involve high heat. These manufacturing processes can leave traces of poisonous heavy metals in the protein formula – that’s why XBrain only uses the most modern and clean methods of production ensuring a safe and healthy mixture.

The use of grass-fed cows’ milk has all of the above health benefits as well as a super-smooth texture and delicious banana flavour. Try it today and experience all of these benefits for yourself.
