Whey Protein Isolate at a glance

  • Fast absorbing
  • May help build lean muscle
  • Assists in recovery
  • Increased protein synthesis
  • May boost immune system
  • Low fat, carbs and lactose

What is Whey Protein Isolate / WPI?

WPI is simply a concentrated form of whey protein. It is designed to be at least 90 percent protein, with much of the fat and lactose normally found in Whey Protein Concentrate filtered out.

WPI is derived from milk and made up of short chain peptides, which means the body can easily absorb the protein, feeding your muscles in as little as 15 minutes after consumption. 

In fact, WPI has a greater biological value (BV) than any other type of protein on the market. This means that it provides the largest useable amount of branched chain amino acids and other essential amino acids. 

In simple terms, it provides essential nutrients that your body can absorb rapidly. Many manufacturers also add aminos such as L-Glutamine & Taurine, to assist with absorption.

When should I use Whey Protein Isolate / WPI?

Due to its superior absorption qualities, WPI is the perfect post-training supplement to assist in immediately fuelling muscles with vital recovery nutrients in this important nutrition window.

Generally speaking, fats slow the absorption of nutrients into the body, however WPI can counter this and aid in more efficient digestion

Further to this, the fact that WPI contains little lactose means that some lactose intolerant people can consume it with no side effects (provided it is mixed with water or lactose-free milk).

What are the health benefits of Whey Protein Isolate / WPI?

Studies have revealed a strong link to immune system protection and the ability to act as an antioxidant, so much so that people with immune deficiencies have been known to supplement with it to increase antioxidant levels. 

WPI can also increase glutathione levels, which may lead to decreased chances of developing prostate cancer. 

Who should use Whey Protein Isolate / WPI?

WPI is very important for bodybuilders, dieters and just about every body

It is essential that protein is consumed daily, as the body cannot store it. Athletes and bodybuilders need a higher average intake at 1.3 grams to 2.0 grams per kilogram. 

WPI stacks well with other muscle building & strength supplements such as pre workout supplements, post workout supplements, GH supplements as well as testosterone boosting supplements including tribulus & ZMA.

Best used with

  • Carbohydrate Powders
  • Glutamine
  • Creatine

Since athletes and bodybuilders work out often, protein levels become depleted. By being a direct precursor to building muscle and essential amino acids, such as glutamine (a muscle enhancer, endurance builder, and muscle deterioration reducer), the content from high quality WPI not only can, but will help one’s muscles recover and grow faster by bringing up the levels of protein.

With dieting and those wishing to lose some extra fat, WPI can be very useful because a good intake of protein balances blood sugar levels, while carbohydrates cause blood sugar levels to fluctuate. 

When the blood sugar levels stay balanced, one is not as prone to rampant eating and has more energy and greater fat loss. WPI allows a person to control his or her diet effectively

Most people who want to change their body for the better could benefit from whey protein supplementation; however, since protein is naturally found in many food items deficiency is usually not a problem.

Whey Protein Isolate / WPI is the Gold Standard of Protein Supplements

Bulk Nutrients Whey Protein Isolate / WPI is a Low temperature Cross and Ultra Filtered WPI which remains completely undenatured. We believe it is one of the purest Whey Protein Isolate / WPI available on the market, with high levels of protein and lower levels of fats, carbohydrates and sodium. Our Whey Protein Isolate / WPI is naturally rich in amino acids, particularly so the branched chain amino acids (BCAAs), Essential Amino Acids (EAAs) and Glutamine which ensures optimum muscle growth.

WPI is separated during the process of turning milk into cheese. There are two major methods for manufacturing WPI, ion exchange filtration and ultra/micro filtration. Ion exchange filtration involves using hydrochloric acid and sodium hydroxide to separate proteins based on electrical charge. Due to the chemicals used in this process, some amino acids and nutrients can lose their value. However, this method does ensure that less fat and lactose are present in the final product.

Ultra and micro filtration utilise semi-permeable membranes which allow small elements such as water, sugars and electrolytes to pass through, whilst preserving larger ones. The difference between ultra and micro is the size of the membrane pores – ultra filtration pores are about four times smaller. Cross flow filtration is a similar variation of this method. This process for Whey Protein Isolate / WPI does not denature (damage) any amino acids or other nutrients.
