WPI Vs WPC - Am I Using The Right Protein?

WPi WPC protein

Choosing a protein powder can be confusing if you’re not sure of the difference between WPI and WPC.

So here’s a quick guide to each of the protein types to give you a better understanding of how each one can benefit your health and fitness needs.


Bare Blends Native Whey Protein Isolate is made in France from the highest quality fresh skimmed milk through the use of microfiltration and ultrafiltration. This unique process gives Bare Blends Native WPI exceptional nutritional properties. As the milk used is less heat and acid treated, our native whey has an excellent amino acid profile. In particular it is rich in the essential amino acid leucine, which has been clinically shown to be the most successful amino acid in muscle synthesis, and cysteine, responsible for the production of the 'master' antioxidant, glutathione.

Our Native WPI is the perfect blend for post-workout. This is due to the very high levels of protein (roughly 26g per 30g serve) and minimal amounts of sugars, carbs, and fats. As it is especially undenatured, it has low acidity and is therefore is unrivaled in digestibility. This product is so low in lactose we have many intolerant customers who have no problems digesting it.

WPI benefits include:

  • Promotes healthy weight loss in conjunction with an active lifestyle
  • An ideal whey protein powder for women and men
  • Assists in lean muscle building
  • WPI helps to combat hunger cravings
  • Assists in lowering blood pressure
  • Boosts immune system function with beneficial immunoglobulins found in whey protein isolate
  • Rich in Branched Chain Amino Acids (BCAA)
  • Whey Isolate is high in L-Cysteine, a precursor to the master antioxidant Glutathione
  • All proteins are gluten free, sugar-free, low lactose and non-GMO

Our New Zealand Whey Protein Concentrate comes from the lush, pollution- and chemical-free grazing grounds of the South Island of New Zealand. The use of hormones is illegal on this dairy herd, and as a result antibiotic use to treat mastitis is far less common. It is made from fresh cheese whey via micro-filtration, and is considered to be the highest quality concentrate in the world. WPC contains important micro-peptides such as betalactoalbumins, alpha-lactalbumins, lactoferrin, and immunoglobulins, all of which possess extraordinary immune system-boosting properties.

Our WPC is a fantastic protein source, more economical and an excellent muscle builder. Our WPC does contain lactose making unsuitable if you are lactose intolerant. It will keep you fuller for longer and has more immune boosting properties with the extra nutrients from the good fats.

WPC benefits include:

  • Promotes healthy weight loss in conjunction with an active lifestyle
  • Assists in building lean muscle
  • Combats hunger cravings
  • Boosts immune system function
  • Rich in Branched Chain Amino Acids (BCAAs)
  • High in L-Cysteine, a precursor to the master antioxidant Glutathione
  • Gluten free, sugar free, low lactose

Another big producer of whey protein is the United States. There are numerous companies in the USA that produce both concentrates and isolates. Bare Blends has chosen not to stock USA WPI or WPC due to the American dairy laws concerning rBGH and GMOs. Inferior whey proteins are also made in China through heat processes resulting in a very cheap impure product.

Whey protein is one of the few sources that naturally contain all 20 amino acids, making it a complete protein. Bare Blends’ whey protein blends have a superior amino acid profile, and are especially undenatured. They provide our bodies with the most functional protein to recover, repair and build muscles, and also boosting our immunity.

The convenience factor of our protein blends is an important one - as with after exercise it is important to fuel our bodies with amino acids straight away so they can begin recovering our muscles immediately.

These blends are also extremely handy for quick, nutrient-dense breakfast smoothies when you don't have time for anything else. Blending up a serve of our WPI with dairy/nut milk or your liquid of choice, with some frozen fruit is a delicious healthy breakfast which will keep you sustained, and contain the protein and amino acids which your body needs to recover and perform optimally.
