Protein Frequently Asked Questions
Which is the best value protein?
In this application, good ole WPC can't be beaten. It has one of the best amino acid spreads available, is absorbed reasonably quickly - but not so fast to limit its effectiveness when frequent shakes aren't possible, yet it tastes good and mixes well.
If you're currently using a name brand 'blend' consider using our WPC, as it's likely to be better nutritionally than your blend at a much better cost.
Which protein is best for night time use?
In the case of a sustained release protein, Micellar Casein is the best choice as it creates a curd in the stomach and resulting in a very slow breakdown. This is the perfect scenario when sleeping or for those who don't want to have frequent shakes.
Micellar Casein also tastes and mixes well and is good value for money.
Which is the best all round protein?
Well, there is a reason WPI is our most popular protein as it really does do it all. It tastes fantastic, mixes very well and is extremely pure nutritionally. It can also be used directly after training or at any time of the day.
If you've previously bought other ‘brand name’ WPIs you will really like ours. No fillers, exceptional purity, and nothing but Whey Protein Isolate.
The second choice for an all-in-one protein is WPC. Better value for money for those on a tighter budget and only marginally less effective.
Should we limit protein to 40 grams per meal? Research solves the mystery.
Which is the best plant protein for muscle building and recovery?
At Bulk Nutrients, our flagship plant based protein for building muscle and aiding recovery is Earth Protein which combines pea and rice protein to create a full balanced spectrum of 18 amino acids. It does this in levels which are ideal for muscle growth, recovery and repair. Have a look at the five best plant-based supplements for muscle growth.
High in specific Branch Chain Amino Acids (BCAAs) and Essential Amino Acids (EAAs), consuming plant-based proteins no longer need to be a compromise.
What is the difference between WPC and WPI?
The key difference between WPC and WPI is that WPI is refined further.
Both products start from the same raw good (liquid whey), however WPI is refined to a further point which gives it a higher protein ratio, less fats, carbohydrates, and lactose.
We go into a lot more detail on the differences between WPI vs WPC in this article.
Should I use WPC or WPI?
This all depends on circumstances. Contrary to what many say, absorption times of both are remarkably similar - both are considered very rapidly absorbing protein sources. Due to this, one is not better post training or as a meal replacement compared to another, so they can be interchanged easily.
If you want the best possible value for money, then our creamy WPC is the better choice. While it has less protein, it's a fraction of the price of WPI. So, for a given amount spent, you'll get more protein and hence better results from Bulk Nutrients' WPC.
If, however, money isn't an issue and you want a more refined product, one which tastes slightly better, is lower in fat and carbohydrates as well as lactose, WPI would be the better choice.
Given the fact our WPI is extremely well priced many people use it anyway, however for the more budget conscious, WPC represents better value for money.
Do Bulk Nutrients proteins taste good?
We may be a little biased, but we believe our whey proteins taste very good.
While taste is subjective, we have carefully refined the flavours of all our proteins over many years and a huge amount of feedback. The result is a level of flavouring and sweetener that most people find very pleasant while not being overbearing.
It is important to keep in mind with any protein product, products are generally a compromise between taste, mixability and purity.
Using very high quality instantised proteins means that our products mix well, however as purity is especially important to us, the flavouring levels have to be used moderately.
We believe we have produced a great combination, with the inclusion rates of our flavourings between 1 and 4%.
If taste is the most important factor to you, you may find some of the USA products from other manufacturers more to your liking, however the product will be far less pure than ours with all sorts of additives and flavour enhancers used to improve taste.
Bulk Nutrients' proteins should be seen as an exceptionally pure option, with no unnecessary additives, and all things considered taste very good.
Are any of your protein's lactose free?
All our whey proteins contain some lactose. Whey Protein Concentrate contains the highest levels, so if you have issues with lactose, then we recommend you avoid WPC.
Our Whey Protein Isolate contains very low levels of lactose, so these are generally fine for lactose sensitive people.
As lactose sensitivity varies a lot. If you are extremely sensitive to lactose you may not tolerate our WPI. In these circumstances you could try our Soy, Rice, or Pea Proteins, however, none are as easy to drink as Whey.
What is the difference between Micellar Casein and Calcium Caseinate?
Similar to the differences between WPC and WPI this generally comes down to refinement and purity. Micellar Casein contains less protein, with more fats and carbs, however unlike Calcium Caseinate it is considered "undenatured". Denaturing is the changing of protein fractions and amino acid profiles due to a heating process - making Calcium Caseinate means using a lot of heat.
"Undenatured" proteins are generally considered an advantage as their amino acid profiles and protein fractions are more natural.
If you want the slowest releasing protein it would be Calcium Caseinate, however as Micellar Casein tastes and mixes better, as well as being undenatured it is the one we usually recommend.
If you were looking at adding either to whey to prolong the release then Calcium Caseinate would be the better choice, however as a stand alone night time protein, Micellar Casein (particularly our flavoured product) is ideal.
If you're still confused which is better for you, we've got this great article 'Why Should You Use Micellar Casein?'.
Why don't you use Stevia instead of Sucralose?
While people see Stevia as safe purely because it is natural, sweeteners such as Sucralose have a lot more safety data, as they have been in extensive use for prolonged periods of time.
In addition to our standard range, we offer a stevia sweetened WPI, and WPC called Natural WPI and Natural WPC. In addition to this our regular WPI and WPC both come in a Raw version which contains no flavours or sweeteners.
