Rated 4.6 / 5 with 5 ratings


With a completely new flavouring system Reflex Nutrition have relaunched their leading whey protein under the new name of Reflex Instant Whey PRO ™.

This protein blend has all the same fantastic features that made its predecessor the number #1 UK protein supplement choice for the last decade. It maintains its unparalleled true 80% protein content with its use of Native Whey and its primary constituent, whey isolate. It also carries forward its use of Probiotics and digestive enzymes, and in fact has used the latest technologies to improve on the original versions with higher, and more effective dosages per serving.

However, where you'll really notice the difference is in the taste. For years, many brands have had thicker, creamier mixes, but at the cost of far, far lower true protein levels often as low as 50% and rarely, if ever, exceeding 72%.

However, with new flavouring technologies, Reflex Nutrition have managed to bring great tasting flavours, great creamy textures and its traditional easy instant mix to a true 80% protein powder.

The current list of flavours is extensive and is growing all the time.

After a sample tasting session here at BodyActive, we can confirm that every single flavour got the thumbs up from the 8 of us lucky enough to do the tasting tests. Our top 2 flavours were the Strawberries and Cream and the Banoffee Pie, but it was a close call with every flavour getting a positive rating from everyone in the testing group.

For those that are interested in the details of the added probiotics and digestive enzymes, we asked Reflex for some further explanation and were told that;

"Instant Whey™ is now called Instant Whey™ PRO in recognition of the 4 probiotics 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: assisting with digestion; improving immune response; balancing digestive transit minimising bloat; inhibiting growth of harmful bacteria. "

They went on to explain;

"The formula has benefits beyong this too, in fact Instant Whey™ PRO continues to deliver additional high quality glutamine peptides and whey peptides in combination with a 25% increase in Digezyme® enzyme complex which provides Protease, Amylase, Lipase and Lactase enzymes."

It looks like 2014 is going to start with Reflex still firmly at the top of the ladder in terms of protein supplement development and delivery.

This product also features in the following categories:

Reflex Nutrition
Protein Powder Supplements

For best results mix in water to ensure optimum release of amino acids into the bloodstream. For normal use between meals, 2 scoops provides around 25g of protein with few carbohydrates or fats, which should be taken as frequently as required, typically 2 to 3 times per day.

One to two scoops can also be used with a solid food meal that is low in protein, such as a bagel or carbohydrate snack.

If used to increase protein levels after training, 2-3 scoops in water is recommended. If calories are not an issue, this should follow 20 minutes after a carbohydrate drink or a ripe fruit snack taken immediately after the workout.

To reduce the speed of release, mix in semi skim milk or drink following a small solid food snack.

2-3 scoops mixed in water and poured over a breakfast cereal dramatically improves the protein level of the first meal of the day.

Taste is sooooo much better. Used to swap between instant whey and optimum gold standard. Ill stick to this now

Rated By: Gary Pickering Rated 5

Ive used every protein powder going over the years and decided that instant whey was the best out there for me so i was dreading it once I heard the formula was going to change.

Thankfully the new PRO version is every bit as good as the original. The same great protein blend and the same added functional extras - and even an improvement in some of them.

But the big change is that the taste is now superb while its still nice and thin and an easy mix. Well done Reflex

My only problem with the new one is the hike in price. Used to be one of the lowest cost proteins on the market and now its pretty much mid priced. Suppose Im been greedy cos it must be one of the best

Another winner from Reflex. Everyone always said you could have the perfect taste OR the perfect protein but not both. Glad Reflex didnt listen

Rated By: Andy Rated 4

The banoffee is superb and the strawberry is as good as any ive tried before. The protein content is mega high and its very low carb so its pretty much the perfect choice. Used to like it in a bag rather than a huge tub as it doesnt fit in my kitchen cupboard anymore
