Muscle Gain & Performance

Ensuring your body receives a regular supply of protein is essential for supporting lean muscle growth. Protein consists of amino acids which are the building blocks of muscle and allow us to build, repair and maintain muscle tissue.

Building muscle mass essentially involves the process of lifting heavier weights, tearing the muscle fibres and then rebuilding them stronger and bigger and this is where regular protein intake comes in. Current research indicates roughly 2.2g of protein per kg of body weight is required for building muscle. For an 80kg male this equates to 176g/day which equates to roughly 30g-40g per meal spread over 5 meals.

Protein can be attained from a wide range of wholefood sources such as fish, chicken, and beef as well as non-animal sources such as quinoa, green peas and nuts. Protein can also be attained in supplement form, most commonly in powders such as whey protein powder, pea protein powder or rice protein powder. These powders allow for a convenient way to add additional protein calories into your daily diet and assist with muscle building needs.

Weight Loss & Toning

The lowest calorie way to consume protein is in a protein shake. Products such as Whey Protein Isolate have extremely low levels of carbs and fats, meaning the calories you consume are virtually pure protein. If you’re looking to minimise your caloric intake and burn any excess fat, a high protein diet is a must. Not only will a high protein diet ensure your body draws its energy from excess fat stores, it’ll also make sure you don’t feel hungry and crave unplanned cheat meals.

Nevertheless, we wouldn’t advise you rely on protein powder as your only source of protein. Rather it should be used to supplement a well-rounded diet.

What is whey protein powder?

Protein powder is essentially a concentrated source of protein derived from either an animal or plant source. Whey protein is a high-quality, complete protein naturally found in cows’ milk. Whey is separated as a by-product of cheesemaking, when enzymes are added to the milk to encourage coagulation, separating the liquid from the solids (curds). The liquid content (whey) is strained off and filtered to remove most of the fat and lactose. For WPC80, the liquid is micro-filtrated and for WPI90 it goes through a second ultra-filtration process that removes further fat and lactose resulting in a more refined whey. The filtered liquid is then evaporated and dried to become a pure whey powder, which is how it arrives at the True Protein HQ, where we blend it with all-natural flavours and package it on site.

What is the difference between True’s Whey Protein Isolate (WPI90) and Whey Protein Concentrate (WPC80)?

The key difference between the two whey protein powders is refinement. Both powders go through a micro-filtration process in their raw state, but WPI90 goes through a further ultra-filtration process that strips away more of the lactose and other elements to give a purer whey with a higher protein content of around 90%. Please see here https://www.trueprotein.com.au/isolate-concentrate-difference for further information.

How is WPI90 flavoured?

We have opted to use stevia to sweeten our flavoured proteins. Stevia is derived naturally from a plant grown in South America and is around 200-300 times sweeter than sugar. We therefore only need very small quantities of this naturally produced sweetener to flavour our protein powders. 

What are the health benefits of WPI90?

- Suitable for vegetarians

- Only trace fat and carbohydrates, perfectly suited for lean muscle gain and fat loss

Can I drink WPI90 if I’m lactose-intolerant?

There is only a trace amount of lactose in our WPI90 protein powder due to the ultra-filtration process it goes through to remove the lactose. You may be able to consume it if you are lactose intolerant or lactose sensitive but should seek advice from your doctor first if you are concerned.

Can I take whey protein without working out?

Yes, it is perfectly safe to drink whey protein without working out, especially if you have a low-protein diet or are recovering from illness. However, it is important to review your own individual requirements to avoid excess protein consumption. It’s also important not to replace whole food sources with protein shakes. Protein supplements should ideally be used alongside a healthy balanced diet.

When should I take my protein powder?

If using your protein alongside an exercise regime then we recommend enjoying a protein shake within an hour of finishing your workout to enhance recovery. Protein shakes can also be consumed at any time throughout the day, depending on your individual needs. The latest scientific research suggests that consumption of 1.2-1.6g of protein per kilogram of body weight per day is an appropriate protein target (1). For example, if your current weight is 80kg then your dietary protein requirements are between 96-128g per day. Our protein can also be used as an ingredient in both sweet and savoury recipes.

Is WPI90 suitable for taking on a ketogenic diet?

Yes, as WPI90 is so low in carbs (approx. 1.9g per 30g serve with water) it is suitable for taking when following the low-carbohydrate ketogenic diet.
