Instant Whey™, our market leading whey protein has now been improved to provide an ever more advanced formulation that is simply unbeaten in the market.

It is now called Instant Whey™ PRO, in recognition of the four ingredients that have been included which deliver a total of 2 billion friendly bacteria per 100 grams of product and include Lactobacillus acidophilus, Bifidobacterium bifidum, Bacillus coagulans and Lactobacillus rhamnosus. These friendly bacteria have distinct and unique characteristics but the formula improvements extend beyond this addition.

The main ingredients in Instant Whey™ PRO are whey isolates which are 90% protein. Some brands include these, but currently none use native whey isolate as a main ingredient; this is the ultimate A+ grade whey protein that is extracted directly from fresh skimmed milk at low temperature, using ultra and cross flow microfiltration resulting in a product that contains up to 166% more bioavailable cystine and 16% more leucine in comparison to other forms of whey.

Instant Whey™ PRO also includes the new improved super CFM (cross flow microfiltration) whey protein isolate, hydrolysed whey proteins and pure undenatured whey protein concentrate - all European sourced and guaranteed to be completely free from rBST, antibiotics and other unwanted impurities. Instant Whey™ PRO continues to deliver additional high quality glutamine peptides, whey peptides in combination with a 25% increase in Digezyme® enzyme complex which provides protease, amylase, lipase and lactase enzymes.

Our R&D team were also tasked with developing the very best flavor and texture profiles. By working with the worlds very best flavor houses, using their very latest technologies, we believe that we have achieved the ultimate balance of the highest quality ingredients, the broadest spectrum of synergistic and innovative ingredients and now what we believe are the market's best flavors and texture.
