Protein Supplement Frequently Asked Questions
Why do you use sucralose as a sweetener in your protein powders? Is it safe?
We've done a huge amount of research and testing on various sweeteners and sucralose has been selected as it is a) the best safety profile, b) tastes most like natural sugar and c) can be used in very small doses, which means purity is maintained.
It is more costly for us to use sucralose than sweeteners like Ace-K and Aspartame, but we think it is a sensible choice. If you're looking for naturally sweetened protein powder, we have a huge range of natural products which use a combination of Stevias and Monk Fruit.
We love promoting completely natural products and highly recommend trying this range!
How do I use protein powder?
Using protein powder is really simple. You start by filling a shaker with water (or milk if you prefer) then add your scoop of protein, put the lid on, shake and drink. We recommend about 5 seconds of vigorous shaking to ensure no lumps.
You can use protein any time of the day, we suggest adding in a protein shake as a side to a meal that is low in protein. For example, if you are a fan of breakfast cereal (which doesn't contain much protein) this is a perfect time to have a shake. A breakfast full of eggs or meat wouldn't really need a shake alongside it.
Protein shakes also make perfect snacks. They're reasonably filling, so mid-afternoon or mid-morning can be a great time if you get peckish.
The most vital time for a protein shake though is directly after training when your muscles are in need of a protein hit (2). This is the single best time to have a protein shake.
How much is a scoop of protein powder?
This varies depending on the density of the powder, but generally, a heaped to rounded scoop contains 30g of protein powder.
Keep in mind 30g of protein powder isn't 30g of actual protein. You will get between 23 and 27g of protein depending on the protein powder supplement.
It pays to know your powders though, which is why we recommend a set of our micro scales. Use them a few times and you'll get a good eye for how much powder you want to take each time.
Does protein powder work? What are the benefits?
Absolutely, and there are many reasons to take it. Buying and using protein powder from Bulk Nutrients, allows you to increase your protein intake in a really cost effective way, conveniently, taking in as few carbohydrates and fats as possible.
Our customers love how easy it is to have a few shakes a day and increase their protein levels by 50g, and you can do so without having lots of carbs and fats, which is difficult with many food sources.
Depending on which protein powder you buy it's very cost effective. Bulk Nutrients' delicious flavoured protein starts from 70 cents a serve, making them high quality and extremely affordable.
Can I drink protein powder while pregnant?
This is something we suggest you ask your doctor / healthcare professional about.
While many women consume protein powder while pregnant, here at Bulk Nutrients we always include the mandatory "supplementary sports foods" warning on all our protein powders which states they should not be taken by pregnant women.
Which is better — Whey Protein Isolate or Concentrate?
This entirely depends on whether you want, maximum value or the purest product possible. If you want maximum value then nothing beats WPC (Whey Protein Concentrate). However much you spend on protein, with WPC your dollar will go further.
WPI (Whey Protein Isolate) is the better choice if you are happy to spend a bit more and get maximum purity. WPI has virtually no lactose and has only tiny amounts of fats and carbohydrates.
Both have similar levels of key amino acids, like BCAAs and EAAs.
The directions say to have a certain amount of water. Can I mix more / less water with my protein?
Yes, these are just general recommendations but we suggest you mix to taste.
If you like your protein thicker or sweeter then use less water (or a larger serve of protein). If you find it a bit too sweet then use more water, or a smaller serve of protein.
There really hard and fast rules, just make sure you are aware of how much protein you are taking in if you are tracking your protein / macro goals.
Will protein powder make me bulky?
No single food will cause you to put on size and appear 'bulky', provided you aren't eating in a large calorie surplus. In fact, a higher protein intake is actually quite beneficial for fat loss as it can aid in satiety and lean muscle maintenance as you lose fat (3, 4).
Pure protein powders such as Bulk Nutrients WPC or WPI contain very little fat and carbohydrates which make them ideal for anyone looking to lose fat and gain lean muscle. However, mass gainers such as our Muscle Food 101 are designed to assist with weight gains so they contain added carbohydrates and fat to help with this goal.
The benefit of a protein powder is they're a very pure, convenient and fast-acting protein source. Protein powders are great to replenish muscles post-workout or add to meals throughout the day in order to meet individual macro/calorie goals.
How much protein do I need per day?
Like anything to do with nutrition it differs from person to person — it all depends on your goal, body weight and level of physical activity.
For example, 1.2g of protein per kg of body weight can be sufficient for sedentary people, while more active people looking to build muscle require more protein to assist with muscle development (anything from 1.4-2.4g per kg of body weight).
For fat loss, a protein intake of 1.8-2.7g/kg can be effective along with a calorie deficit. A higher protein intake of up to 3.3g/kg can be beneficial for anyone bulking and trying to put on size.
From working out your individual protein intake according to goal and exercise regularity, you'll get a starting number which you may need to adjust as you go.
Are some protein sources better than others?
Traditionally whey protein was always considered the "gold standard" for protein as it had one of the highest PDCAAs score (protein digestibility-corrected amino acid score) of 1.0. In recent times though this has been challenged; some people would claim Casein (which is more slowly digested) and even plant sources are better (5, 6, 7).
At Bulk Nutrients, we believe the protein which suits you best and the one you will regularly take is the best one. For example, if you have issues digesting lactose or dairy, then we would not recommend a whey-based protein.
Which protein is best will also depend on your goals. As another example, Hydrolysed Collagen Peptides is a poor protein as a primary muscle builder. However, if you are primarily concerned about skin, bone and joint health then it may be the best choice (8).
We always recommend combinations for best results and balance. Timing is important too, Casein at night is great (when you want slow absorption) with WPI great directly after training when you want rapid absorption (9, 10).
