Instant Whey™, our market leading whey protein for close to 2 decades. Thousands of athletes have praised this product, relied on it year round and enjoyed the guaranteed quality that’s built into every single tub which now tastes just like a milk shake, it utilises our amazing new flavour technology and it’s our best tasting version yet!

It also has now been improved to provide an ever more advanced formulation that is simply unbeaten in the market. In fact we’d argue that it is the best whey blend product you can buy in the world today. £ for £ compared to nearly all of our competitors it delivers more protein, tastes better, gives a guaranteed protein content and delivers extras like friendly bacteria & digestive enzymes;

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 EU 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 whey protein isolate, hydrolysed whey protein and pure undenatured whey protein concentrate – all European sourced from grass fed dairy cattle 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 flavour and texture profiles.  By working with the worlds very best flavour 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 flavours and texture.

4 reviews for Instant Whey™ PRO With Whey Protein Isolate

5 out of 5 :

Tried just about nearly every protein powder on the market, all the usual USA stuff but I’m pleased to report that Instant Whey Pro beats them all for me. The only with 80% protein in chocolate flavour is the winner for me. Mixes well and tastes amazing. The quality and guarantee gives great piece of mind.

Tastes good and mixes well blah blah – but the main reason I use Reflex is because I trust the brand. With all the dodgyness about label claims I will only use a brand I know I can trust and that make their own products and not just some relabelled generic rubbish

5 out of 5 :

My favourite protein powder especially in strawberry flavour. Mixes easily and tastes amazing.

5 out of 5 :

Awesome product, tastes amazing mixes easily. 80% protein!! Really all what you could want, bit pricey but I guess you get what you pay for. Overall I think this is the best whey protein your money can buy, especially with the Native Whey Protein Isolate.
