NZ PROTEIN WHEY ISOLATE 1KG

Premium NZ Grass-fed whey isolate protein

Fast Digesting and Ultra High Protein From New Zealand Grass Fed Cows.

Whey Protein Isolate (WPI) is premium ion exchange protein powder. Our product is made in New Zealand (NZ) from grass fed cows.

Whey is a milk product and is a by-product of cheese. Whey contains high levels of protein with some lactose and fat. Isolate (this product) is made by further refining whey to remove virtually all of the lactose and fat, leaving a product that’s ultra-high in protein with a superior Branched Chain Amino Acid (BCAA) profile.

WPI is a concentrated protein powder for muscle development. It has a very strong amino acid profile and is one of the most beneficial dietary sources of protein. It’s very easy to digest and absorbs rapidly, making amino acids readily available to be utilised by muscles. It’s a very beneficial protein supplement for post exercise when it is able to digest easily without fat to slow absorption.

It has a pleasant, clean taste and is popular with athletes and those counting their macro-nutrients. It’s also generally suitable for those with lactose intolerance.

Whey Isolate Benefits

WPI is a powerful muscle builder because it has all 21 amino acids needed for growth and repair. Each serving (unflavoured) contains over 29 grams of protein and nearly 8 grams of BCAAs.

WPI has higher levels of leucine than other protein powders. In fact, WPI has more than 30% more leucine than WPC. Studies of leucine have shown it to be the most anabolic (growth promoting) amino acid for muscle growth and recovery. Leucine also contributes to the regular of blood sugar levels, growth hormone production and wound healing.

WPI may assist atheles to benefit from increased lean muscle mass, reduced muscle atrophy during exercise, improved muscle repair and recovery (hyperatrophy), and an increased metabolic rate.

Other Benefits:
Whey is composed of several bioactive fractions including glycomacropeptide, β-lactoglobulin, α-lactalbumin and lactoferrin. These have health benefits against cancer, infection and inflammation.

WPI is high in cysteine and studies have shown that WPI can increase glutathione synthesis to improve antioxidant defence. Glutathione is a natural antioxidant that the body produces from several other amino acids – especially cysteine.

Bioavailability

Protein digestibility is a measure of the proportion of protein that is absorbed by the body. WPI scores 100% on this scale.

Biological value is a measure of the proportion of absorbed protein that’s retained for growth and maintenance. WPI scores 104 on this scale.

The Protein Digestibility-Corrected Amino Acid Score (PDCAAS) is a rating that determines the bioavailibility of a protein. The maximum score is 1.0. WPI technically scores 1.0 because traditionally protein quality was measured against milk, which scored 1.0. Though the scale only goes up to 1.0, realistically it may be up to 1.21, which is the highest of all protein sources.

Whey Isolate Side Effects

Whey isolate is generally well tolerated, even by those with lactose intolerance. WPI is a milk product so those with milk intolerances and vegans should avoid this product.

Our Verdict

Whey isolate is whey that’s further refined to remove virtually all lactose and fat. The resulting protein and BCAA levels are higher but it’s also more expensive than whey concentrate (WPC).

It is a superior protein powder because it has the most concentrated amino acid profile and is absorbed rapidly without fat to slow digestion. It surpasses other proteins for bioavailability so is the best protein powder for post exercise for those wanting maximum muscle recovery/development.

It is more expensive so consideration must be taken whether WPI is better suited to your requirements vs regular WPC. This decision comes down to personal preference.
