Whey Protein Powder - Which one is right for me?

What is whey protein powder?

Whey Protein powder is a highly refined source of the protein nutrient found in cow milk, in a powdered form.

How whey is made?

Whey is a product from the dairy industry. After fresh milk is pasteurized to make it safe for human consumption the liquid whey is separated from the milk. Liquid whey is then refined by filtration and finally heat dried into a powdered form. It is at this point that difference between whey concentrate and whey isolate created, with whey isolate undergoing an extra stage of filtration. This extra step creates an ultra-refined whey isolate with lower fat, carbs, lactose and a slightly higher protein profile than its whey concentrate counterpart.

Just as important as the processing techniques is where the raw milk is sourced.  Dairy is New Zealand’s largest export industry and New Zealand milk is commonly regarded as the highest quality in the world.  Go Good’s whey protein powder is sourced from New Zealand’s clean, grass fed, hormone and chemical-free dairy cows.

Whey protein offers a complete BCCA profile. It contains all of the Branch Chain Amino Acids necessary to fuel your muscles

Whey protein is the dominant form of protein supplement because it offers a complete BCCA profile, it contains all the Branch Chain Amino Acids necessary to fuel your muscles. It is a fast absorbing and easily digested protein,  great for muscle growth and recovery.

WPC or WPI, which one is right for me?

Again, both WPC and WPI will help you achieve and maintain health and wellness goals. The amount of fat and sugars left in our whey protein concentrates are really minimal and lactose acts is a helpful immune regulator.

Experience tells us that WPI is the preferred option for competitive athletes and people with strict dietary targets or requirements - such as lactose-intolerant.

An example for the health committed may include protein isolate for consumption directly after a workout or training session when protein nutrients are the most effective, and a protein concentrate for all other consumption throughout the day to increase protein intake.
