Whey Protein Isolate Unflavoured. I really enjoy this produced as I can add it into anything or have on its own to hit my protein target at low calories.

Stacey Rennie

5 stars all the way. My kids love it, my cat loves it, I even use it instead of petrol in my car and it goes harder than ever. 10/10 recommend.

Flynnie McGee

It has been difficult looking for a protein powder without the horrible nasty fillers. Protein Supplies Australia’s WPI vanilla bean blends smoothly into milk or water and tastes great. I highly recommend trying this product and all the others offered.

Compared to other protein sources, our WPI protein is naturally rich in branched chain amino acids (BCAAs) and essential nutrients to enhance muscle protein synthesis and aid muscle recovery. Every delicious protein shake—available in Vanilla, Banana, Chocolate, and Choc Peanut Butter flavours—delivers rapid absorption, high bioavailability, and outstanding results for those looking to build lean muscle and maintain muscle mass.

The process of transforming liquid whey into pure whey powder involves advanced ultra filtration and drying techniques, ensuring a high-quality, concentrated protein derived from milk. Crafted for sensitive stomachs and those seeking gluten free and low-lactose solutions, our WPI range provides clean protein supplementation with no fillers, artificial additives, or soy products.

Is Whey Protein a Good Meal Replacement?

Our whey protein powders can be used as part of a meal replacement plan when combined with a balanced intake of other nutrients like healthy fats and fibre.

What’s the Difference Between WPI and Casein Protein?

WPI is fast-digesting, making it ideal for post workout recovery, while casein protein digests slowly, better suited for overnight muscle repair. Additionally, whey protein concentrate (WPC) retains more fats and carbohydrates compared to WPI, making it a suitable option for those seeking a complete source of protein.

Our WPI powders are naturally low in carbs and fats, making them perfect for supporting protein intake on a keto diet.

How Much Protein Do I Need Daily?

Protein needs vary by body weight and goals, but a general guideline is 1.6–2.2g per kg of body weight for muscle growth and recovery.

Can People with Sensitive Stomachs Use WPI?

Yes. Our WPI includes digestive enzymes and probiotics, making it gentle for those with sensitive stomachs or lactose intolerance.

What is 100 Whey Protein Isolate?

100 Whey Protein Isolate is a type of protein powder that contains 100% whey protein isolate, with minimal fats, lactose, and carbohydrates. It is considered one of the purest forms of protein powder available, making it an ideal choice for those with sensitive stomachs or dietary restrictions. Rich in branched-chain amino acids (BCAAs) and essential amino acids (EAAs), whey protein isolate is crucial for muscle protein synthesis and lean muscle growth. This high-quality protein source supports muscle recovery and helps you achieve your fitness goals effectively.

What are the Types of Protein Powder?

There are several types of protein powder available, each with its own unique characteristics and benefits. Understanding the differences can help you choose the best protein powder to meet your specific needs and goals.

Whey Protein vs Casein Protein

Whey protein and casein protein are two of the most popular types of protein powder. Whey protein is a fast-digesting protein that is rich in BCAAs and EAAs, making it ideal for post-workout recovery and muscle growth. Its rapid absorption helps kickstart muscle protein synthesis immediately after exercise. On the other hand, casein protein is a slow-digesting protein that provides a sustained release of amino acids, making it suitable for consumption before bedtime or between meals. Whey protein isolate, a more refined version of whey protein, boasts a higher protein content and lower lactose levels, making it an excellent choice for those seeking a pure and efficient protein source.

Protein Powder Varieties

In addition to whey protein and casein protein, there are several other types of protein powder available, including plant-based options such as pea protein, rice protein, and hemp protein. These protein powders are often gluten-free, soy-free, and hypoallergenic, making them suitable for those with dietary restrictions. Protein powder supplements can also be fortified with additional ingredients such as sunflower lecithin, vegetable gum, and frozen berries to enhance their nutritional profile and taste. When choosing a protein powder, it’s essential to consider factors such as protein content, ingredients, and nutritional information to ensure you’re getting a high-quality product that meets your needs.
