Frequently Asked Questions

Whey Protein

Why Whey Protein?

There is a range of protein powders available in the market some of which you may be familiar with including whey, egg white, pea, brown rice, hemp and soy. The biggest difference between these protein sources is their effectiveness. Whey protein is known for being quickly digested, improving immune function and has the highest amount of BCAAs compared to alternative protein sources. When comparing whey protein with other protein sources they fall short of the standards set by whey protein i.e. lack a comparable protein profile (80% and above), they are deficit in certain amino acids, they have questionable sources or side effects or the sheer cost makes them impractical to consume on a daily basis. From experience the only reason why people would choose a different protein other than whey is due to dietary choices or allergies.

What does unflavoured whey protein taste like?

Our natural unflavoured WPC & WPI range is the best value for money you will find. Most users say they already notice a taste difference between conventionally flavoured whey and our organically flavoured lines, our unflavoured whey is a step back again. As whey is essential derived from cows milk you can expect the product to have a milky taste, quite similar to milk powder. When mixed with milk the taste is hardly noticeable however when mixed with water the taste becomes evident. Typical feedback has informed us that it takes most people up to 2 weeks to get used to the flavour (or lack of) but at the same time it will serve as a reminder of how many artificial flavours & fillers there are in most of the products available in the market. Being natural in flavour you also cannot deny the range of possibilities available to flavour your shake.

Why New Zealand whey?

Unlike other dairy producers the New Zealand industry has banned the use of Recombinant Bovine Growth Hormone (rBGH). rBGH is a genetically engineered hormone injected into American dairy cows to increase milk production. Additionally these cows are usually raised on un natural corn or soy based diets and injected with antibiotics to survive sanitary conditions. The United States and Brazil are the only developed nations that legally permit humans to drink milk from cows given this artificial growth hormone. Consequently many sports supplement brands manufactured in the USA are made using whey protein powders derived from rBGH treated cows on US farms.

New Zealand dairy cows maintain a natural diet grazing on lush chemical free grass pastures. The use of Recombinant Bovine Growth Hormone is illegal and the practise of using antibiotics to treat disease far less common. Processing techniques are world leading ensuring the maximum benefits are withheld in the final whey product during the filtration process. The combination of these factors results in New Zealand having a reputation for the highest quality dairy (and therefore whey powder) in the world.

What is native whey?

Native whey protein usually refers to whey protein isolate. Whey protein isolate is extracted from skim milk micro-filtered and then ultra-filtered to remove essentially all of the fat and lactose. The result is a very pure whey protein product with a high protein profile. See more on the differences between whey protein isolates and concentrates on our information page.

What is organic flavouring?

This is the purest way to flavour a food. Utilising actual ground fruits and beans cultivated and processed in a manner that preserves the nutritional properties we ensure only the highest quality ingredients are blended with our whey powders.

What is the recommended serving size?

1kg equates to 33 30gm serves. This is based on industry standard for the average individual. Taken once daily a 1kg canister will last just over 1 month. Those who are looking to increase lean muscle mass or who participate in regular physical exercise will require a larger amount that reflects energy outputs and demands.

I personally have 2 protein shakes per day, one with breakfast and one after my workout (on training days) this reduces consumption time of 1kg to 2-3 weeks. I recommend experimenting until you find a quantity that suits your personal demand and preference.

I am having trouble mixing my whey

Whey protein mixes best with the use of a power blender. Smaller compact blenders are great for quick servings while bigger blenders are good for making fruit & vegetable smoothies.  The second best option is to use one of our Wheyhouse protein shakers that includes a blender ball for optimal mixing consistency.  If it can be helped stirring with a spoon should be avoided as it is timely and the whey does not mix consistently.

Is Wheyhouse whey protein pasteurised?

Yes.  It is illegal in New Zealand for milk products not to be pasteurised. Pasteurisation is a process of heating the milk to 72°C and holding it at this temperature for 15 seconds.  The aim of pasteurisation is to remove harmful bacteria that may be present the rawest form of milk without affecting the nutritional characteristics of the milk. Here in New Zealand we have some of the most technically advanced processes to ensure this.

Is Wheyhouse whey high or low temperature pasteurized?

Low temperature. The pasteurisation process for our whey follows New Zealand (and industry standards) which is the HTST High Temperature Short Time method.  Contrary to its name it is low temperature pasteurisation. The initial standard for milk pasteurisation in 1927 was set at 61°C for 30 minutes over time revisions have been made and when measured against this benchmark the current temperature of 72°C is higher. For comparisons sake high temperature pasteurisation is between 120°C – 135°C which is usually reserved for long life milk products.

Women

Will I get bulky if I take whey protein?

While women typically fear that they will bulk up using whey protein quite the opposite is actually true. Women do not have the essential hormones required to build large muscle mass found in men. Female bodybuilders prove this by having to take hormonal supplements that intentionally build larger muscle mass. If used in conjunction with well-balanced diet women should see an increase in muscle tone, accelerated metabolism and a reduction in body fat.

Can whey protein be taken as a meal replacement?

Although the primary reason for any sports supplement is to supplement an already healthy diet, whey protein in cases can be used as a meal replacement. Although it is not recommended to substitute any of the main daily meals users can benefit from taking whey shakes between meals. It can be easily added to most smoothie recipes for added nutritional value and a protein hit.

Athletes

When is the best time to take whey protein

The optimal time to consume whey protein is within 30 minutes of post workout or physical activity when your muscles are in most need of essential protein nutrients for muscle repair, growth and recovery. Whey protein may also be taken throughout the day as preferred and makes an excellent addition to breakfast and lunch meals.

Is WPI or WPC better to increase lean muscle mass and growth?

A combination of both, WPI directly after training or physical activity and WPC throughout the rest of the day. WPI is a very high profile protein source with a fast absorption rate making it ideal for post workout muscle replenishment and recovery. WPC is a high profile slightly slower digesting protein source with a broader amino profile great for keeping muscles and the body fuelled and full throughout the day. WPC should be a staple addition to anybodys diet that carries out regular physical activity.

Pregnancy

Is whey protein ok to take during pregnancy?

Whey protein is safe to use during pregnancy however it is recommended users consult with health professionals.

Whey protein concentrate makes up a substantial portion of most infant formulas and is therefore used as a staple source a childs nutrition following child birth.

Storage

How do I store whey powder?

Whey powder keeps best stored in a cool dry pantry or cupboard but may be kept in the fridge if preferred. Avoid moisture and always reseal the package after each use.

What is the shelf life of my whey powder?

Shelf life is generally 18 months from the date of manufacture. Best before dates are clearly printed on the package. As we only use real organic ingredients some flavours may have a lower shelf life than others.

Special Dietary Requirements

I am lactose intolerant can I still use whey protein?

Whey protein is derived from dairy however due to the virtually non-existent lactose levels found in whey protein isolate (WPI) it is generally accepted that this is OK to use for those who are lactose intolerant or sensitive. As cases vary, if individual sensitivity is high it is recommended that a health professional is consulted prior to use.

Is whey protein ok for diabetics

Research supports that type 2 diabetics show a higher insulin response after consuming whey protein. The increased insulin response was accompanied by a lower post consumption blood sugar level.  Researchers suggest diabetics look for a whey protein without added sugars. Perfect as our flavoured whey powders are as close to natural as you will find with no added sugars. For those are conscious of their sugar intake our unflavoured (original) whey protein concentrate or isolate is recommended. You will not find a cleaner more natural source of whey powder.

Is Whey Protein Paleo

Although Whey Protein does not technically fit a paleo diet our unflavoured range is as close to paleo as you can get. Whey protein is one of the most researched supplements in the health & fitness domain for a reason and is highly recommended as a dietary supplement for individuals completing strenuous exercise for performance & recovery reasons. So the use of whey protein as a supplement is something we feel is very important to consider if following a paleo diet coupled with a physically demanding lifestyle or exercise regime.
