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. 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 there are no lumps.

When should I take protein powder?

Protein powder can be taken at any time of the day. To start, we suggest adding 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. Conversely, 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.

It’s also very beneficial to have your protein powder right after training when your muscles are fatigued and you need a protein boost ().

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 with ease.

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.

In addition to being delicious, our protein supplements are also cost-effective. We’re passionate about offering protein supplements in Australia that don’t strain your budget, which is why our delicious protein starts from 70 cents a serve.

Can I drink protein powder while pregnant?

We suggest consulting a doctor or healthcare professional before taking any protein powder from Bulk Nutrients.

At Bulk Nutrients, we always include the mandatory "supplementary sports foods" warning on all our protein powders, which states that 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 oir less water with my protein?

Yes, these are just general recommendations —you can add more or less water until it suits your taste.

If you like your protein thicker or sweeter, then use less water (or add a larger serving of protein powder). If you find it a bit too sweet then use more water or a smaller serving of protein.

When it comes to how you ingest your protein powder, there really aren’t any rules. Just be sure you’re aware of how much protein powder you use if you’re tracking your protein or 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 (, ).

Pure protein powders such as Bulk Nutrients WPC or WPI contain very little fat and carbohydrates, which makes 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 gain, so they contain added carbohydrates and fat to help with this goal.

Protein powder is a very pure, convenient and fast-acting protein source. This makes it great for replenishing muscles post-workout or adding 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.

Using your goals and exercise frequency to determine your protein intake, you'll find a starting number that you can adjust as you progress.

From working out your individual protein intake according to goal and exercise regularity, you'll get a starting number that you may need to adjust as you go.

With a new study on recommended daily intake (RDI) we have a look at how much protein should we be having.

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. Recently, however, this has been challenged; some studies claim Casein (which is more slowly digested) and even plant sources are better (, ).

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 ().

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 (, ).
