Cheap Whey Isolate NZ

This product is a great value Whey Protein Isolate (WPI). It's cheaper than the New Zealand WPI and the main difference is that it's from Ireland instead of NZ.

This is a high quality product and comparable alternative for those who don't have money growing on trees. The reality is that NZ milk products are expensive to buy.

Here's how it compares to the NZ counterpart:

What is Whey Protein Isolate

Whey Protein Isolate (WPI) is a better form of whey protein. It's basically whey that's been further refined to remove virtually all of the lactose and fat.

That leaves a product which is ultra-high in protein with a superior Branched Chain Amino Acid (BCAA) profile. It has more protein and BCAAs than regular whey.

WPI has a strong amino acid profile making it a concentrated protein powder for muscle development. It's easy to digest and absorbs rapidly, making amino acids readily available to be utilised by muscles. It's these key attributes that make WPI one of the most beneficial forms of dietary protein.

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.

Best Time to Take WPI

WPI is especially beneficial when taken post exercise. due to its rapid digestion and nutritional profile.

This is because WPI has virtually no fat to slow digestion so it's digested rapidly and easily.

The texture of WPI is more watery than in regular whey or in other protein powders such as pea. This may mean that it's not as fulling as some other types.

Whey Isolate or Whey Concentrate

The main difference between WPI is that it's been refined further than whey to remove virtually all of the lactose and fat.

WPI therefore has more protein than regular whey protein as well.

The other main difference is that WPI has a naturally watery texture, whereas regular whey is creamier. The creamier texture makes regular whey taste better than WPI.

We do not add any fillers or thickeners to our protein powders to modify this texture, as they tend to dilute the protein content and can slow digestion.

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 nearly 29 grams of protein and over 7 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.

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. It is, however, vegetarian friendly.

Our Verdict

WPI 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.

This product is great value and is only slightly more expensive than our regular NZ Whey Protein.

It's a pity that NZ milk prices have become so high, but this is certainly a viable alternative.

Please note that this product is processed in a facility that also handles egg, soy, peanut, and gluten ingredients.

A good WPI and certainly a great "value" for money. I'm a big fan of the NZ WPI, but decided to give this one a go. In comparison, it seems to be secondary for mixing and texture. The flavouring is somewhat not the same either. Trying various flavours - the choc marshmallow is just strange...
Overall a decent option. Personally, I can't wait to go back to the NZ WPI once I get through the remaining bags of this one 😒

As a protein powder beginner, this is super easy to use, no weird taste or texture, good value for money. I will get the NZ made one next time though as the small extra cost is worth it to support local.

Really enjoying the butterscotch and caramel one for a change. Thanks, hope you bring out more flavours as well
Review by: Anonymous on Tue, Apr 13, 2021 1:36 PM
Easy to mix and super affordable for good protein powder with minimal ingredients!! I prefer the vanilla to the butter scotch caramel but it's still yum (I just add a little less). Overnight shipping was amazing too. Definitely recommend!!

Need more flavours, hazelnut, peanut butter, vanilla oatmeal, strawberry cheesecake & more
Review by: Swapnil on Wed, Mar 31, 2021 3:28 PM
Disappointed. Little flavour, very watery mixture (even tried with almond/coconut milk, not just water). Will be going back to the pea protein next. NZPROTEIN REPLY: this product only needs half the amount of water that the pea does which you are used to. WPI is naturally watery in texture because it has virtually no fat and is very fast digesting....
Review by: Sonya on Mon, Mar 29, 2021 2:39 AM
Tastes great, super smooth and not powdery. And the delivery is super fast!
Review by: Anonymous on Tue, Mar 23, 2021 7:47 PM
The flavour was not as nice as I expected it to be - butterscotch caramel.
I wish there was a salted caramel value whey isolate. NZPROTEIN REPLY: WPI has a naturally watery texture (it's very fast digesting with very low fat). We do not add any agents to modify the texture and mouth feel.
Review by: Michelle on Tue, Mar 23, 2021 6:41 AM
Absolutely amazing! I love the flavour and it's a really good clean hit of protein for low calories.

Plus the service is unbelievable. I placed my order at 5.18pm on Friday and by 6.35pm the order had already been shipped, I then received it on the Tuesday (and I live in Invercargill). And to take it to the next level my order contained a hand written note thanking me for my purchase and telling me to enjoy the flavour.

You definitely have a repeat customer on your hands!

Great mixing and neutral flavour, works well on its own or with a dash of Milo or instant coffee. Ideal if you're coming off a bulking round of WPC and need to clean up your calorie count.

Whey isolate is kinder to my stomach, but I can't get on with the flavored whey, so this one is great. Dissolves really easily and I can add it to my coffee or just have it in my water bottle.

Cant complain. First time having pure whey protein after switching from mass gainer. I was surprised at how little water it needed to dissolve well. Taste is fine. Will buy again.

Review by: CRAIG on Wed, Jun 24, 2020 5:19 AM
Is good source of cheap whey isolate. But unfortunately the flavour isn't very strong, so can taste a bit watery.

Great value, I use this to make high protein low carb bread and baked goods, it is just awesome!!!
Review by: Annie on Thu, May 7, 2020 9:50 PM
The chocolate flavour was lacking any real flavour or even a hint of sweetness you'd expect from chocolate. Thickens up significantly more than other isolates I have used. A little disappointed in the overall taste. NZPROTEIN REPLY: we went for a darker type chocolate with this one - it is less sweet. You can't compare it to imported American ones, we don't do sickly sweet.

Love this powder, it doesn’t alter the flavour of my smoothies in a strange way like other powders did. A nice natural powder!
Review by: Sally on Thu, Apr 16, 2020 7:22 AM
Cheaper than the NZ whey isolate, creamier and slightly less refined, leading to more gas and bloating. Would only rate it 3 if it didn't taste so good, next time I will stick to the NZ product.
