Collection: Whey Protein Isolate

Whey isolate is the cleaner take on whey. It’s filtered further than standard whey, which usually means more protein per serving and lower sugar and fat. If you want a leaner shake for everyday protein targets, cutting phases, or you’re just picky about macros, whey isolate is hard to beat.

PER4M Isolate Zero is built for people who want performance nutrition without grim flavour. Expect dessert-level taste, smooth mixability, and a simple spec that fits most routines: zero sugar and 100% whey isolate, with 26–27g protein per serving depending on flavour.

What makes whey isolate different?

Whey concentrate (standard whey) is a more rounded option that typically includes a little more carbs and fat. Whey isolate is processed further to reduce those extras, so it’s often higher in protein by weight and lower in lactose.

In real-world terms: isolate is a great pick when you want a leaner shake, you’re tracking closely, or you prefer something that sits lighter.

Who whey isolate is for

• Cutting or staying lean: Higher protein per serving with fewer extras makes isolate a popular choice when calories are tighter.
  
• Macro-focused routines: If you like your nutrition simple and predictable, isolate keeps things tidy.
  
• People who want lighter shakes: Many find isolate easier to drink daily, especially with water.
  
• Those sensitive to dairy: Isolate is typically lower in lactose than standard whey, so it can be an easier option for some people. It’s still milk-based, so it isn’t dairy-free.
  

How much protein do you need?

Your ideal intake depends on body weight, training volume, and goals. For most exercising people, a commonly used evidence-based range is 1.4–2.0g of protein per kilogram of bodyweight per day.

For servings, a useful rule of thumb is 20–40g of high-quality protein per feed, spread across the day. One of the big takeaways from the research is that consistency matters more than perfect timing, and pushing total intake well beyond ~1.6g/kg/day doesn’t seem to add much extra for most resistance-trained outcomes.

When to take whey isolate

Post-workout: Easy, convenient, and a common time to plug a protein serving in without thinking.

Breakfast: If your mornings are low-protein, isolate is the quickest upgrade. Add it to oats, yoghurt, smoothies, or coffee-style shakes.

Between meals: Useful when you want something fast that supports your daily total.

Any time you’ll stick to: Total daily protein matters most. Put it where it helps you stay consistent.

How to use isolate beyond shakes

• Yoghurt bowls: Stir in for a thick, dessert-like texture.
  
• Oats and porridge: Mix in after cooking to keep it smooth.
  
• Smoothies: Easy protein without changing your usual recipe.
  
• Baking: Works well for higher-protein treats when you keep portions sensible.

FAQs

What is whey isolate?

Whey isolate is a filtered form of whey protein designed to deliver a high protein content with lower amounts of carbs, fat, and lactose compared to whey concentrate. It’s popular for leaner nutrition and easy daily use.

What’s the difference between whey concentrate and whey isolate?

Whey concentrate is less filtered and typically includes slightly more carbs, fat, and lactose. Whey isolate is filtered further, usually giving you more protein per serving and a cleaner macro profile.

Is Isolate Zero really zero sugar?

Yes, the Isolate Zero range is positioned as zero sugar on the product pages. If you track closely, always check the nutrition panel for the specific flavour and serving size.

Can I use whey isolate if I’m lactose intolerant?

Isolate is typically lower in lactose than standard whey, so some people tolerate it better. It’s still a milk-based product, so if you’re highly sensitive, start with a smaller serving or choose a non-dairy option from the Plant Protein range.

How many servings should I take per day?

Most people use 1–2 servings daily depending on how much protein they get from food. The goal is to fill gaps, not replace all meals with shakes.

When’s the best time to take whey isolate?

Whenever it helps you hit your daily protein target consistently. Post-workout is convenient, but breakfast and between meals are just as useful if that’s where your routine needs support.

Can I mix isolate with creatine?

Yes. Creatine works through daily consistency, and a shake is an easy place to add it. Just keep it simple and stick to the routine.

Isolate vs clear whey: which should I choose?

If you want a creamy shake, pick isolate. If you want a lighter, juice-style drink, go for Clear Whey Hydrate.
