Reflex Isolate Pro is the brand's purest whey protein, delivering 25g of protein per 30g serving from cross-flow micro-filtered whey isolate. At around 83% protein, it's stripped of almost all the fat, sugar and lactose, leaving a light, smooth shake that's quick to digest. Added enzymes help your body break the protein down and absorb more of it, making it precision protein for lean, focused muscle recovery.

Isolate Pro is a whey isolate, filtered further than concentrate to remove almost all the fat, sugar and lactose — so it's around 83% protein versus roughly 71% in a concentrate like Reflex 100% Whey. The result is a leaner macro profile (under 0.5g fat, 0.5g sugar, 103 calories per serving), a lighter texture and faster digestion. Choose Isolate Pro when you want maximum protein purity with minimal extras; choose concentrate for a richer, creamier shake at lower cost.

Yes. Isolate Pro is well suited to a calorie-controlled diet because it delivers a high 25g of protein for just 103 calories per serving, with almost no fat or sugar. High-protein, low-calorie intake helps preserve lean muscle while you're in a deficit and supports feeling fuller, making it a popular choice for anyone leaning down or tracking macros closely.

Isolate Pro is designed to be light and easy to digest. The micro-filtration process removes almost all the lactose, and it includes a digestive enzyme complex (DigeZyme®, which contains lactase) plus friendly bacteria (LactoSpore®) to support smooth digestion and absorption. This makes it a good option if you find standard whey heavy or feel slightly sensitive to lactose — though, as a dairy product, it isn't suitable for anyone with a milk allergy

Take 1–2 servings daily, ideally straight after training when fast-digesting protein is most useful. Mix 30g (around one heaped scoop) with 150–200ml of water or skimmed milk, adjust the liquid to your preferred consistency, and drink immediately. Weighing your serving on scales is more accurate than relying on the scoop, which measures volume rather than weight.
