Protein Isolate
Shop Protein Isolate at Myprotein
Protein isolate is the most refined form of protein powder available — processed to remove the majority of fats and carbohydrates, leaving behind a high-concentration protein source. Whether it's whey isolate, soy isolate, or pea isolate, the defining characteristic is purity: more protein per gram, less of everything else. Protein contributes to the growth and maintenance of muscle mass1, making isolate a logical choice for anyone who wants to hit their protein targets without unnecessary extras.
The range covers both animal-based and plant-based options, across multiple formats — from classic powders to clear, juice-style drinks. Whatever your dietary preference or training style, there's a protein isolate here built around the same core principle: maximum protein, minimum filler.
Who Protein Isolates Are For
Protein isolates are built for people who are deliberate about what goes into their body. That might be someone tracking macros tightly, an athlete competing in a weight-category sport, or someone who simply wants a lean, high-protein option without the calories that come with less refined powders. Because the fat and carbohydrate content is stripped back significantly, isolates naturally fit into calorie-controlled diets without much adjustment.
They're also a strong choice for anyone who finds standard whey concentrates difficult to digest. The filtration process that produces isolate removes much of the lactose too, which many people find easier to tolerate. If you've been put off protein powders before, an isolate format is worth trying.
When to Use Protein Isolate
The most common time to use protein isolate is immediately after training, when getting protein in quickly is the priority. Isolate — particularly hydrolysed whey isolate — digests rapidly, making it a practical post-workout choice. A shake takes minutes to prepare and delivers a concentrated hit of protein when you need it most.
That said, protein isolate isn't restricted to post-workout use. It works equally well as a high-protein breakfast addition, a mid-morning snack, or a way to top up your daily protein intake at any point. The key is simply consistency — hitting your protein targets across the day matters more than precise timing for most people.
Protein Isolate Benefits
High Protein Per Serving
The defining feature of a protein isolate is the protein content. By filtering out fats and carbohydrates, isolates deliver a higher percentage of protein per gram than concentrate-based options. Impact Whey Isolate Powder, for example, provides up to 26g of protein per serving — a significant amount in a single, convenient dose. Protein contributes to the growth and maintenance of muscle mass1 and to the maintenance of normal bones2.
Lower in Fat and Carbohydrates
Because of the additional filtration involved in producing isolate, fat and carbohydrate content is reduced compared to less refined protein sources. This makes protein isolate a practical fit within calorie-controlled eating plans, where every macro counts and there's less room for incidental fat or carbs from supplements.
Multiple Format Options
Isolate isn't just available as a classic shake. The range includes clear, juice-style proteins made from hydrolysed whey isolate — light, refreshing, and nothing like a traditional protein drink. There are also plant-based isolate options for those avoiding dairy, meaning the format flexibility matches the dietary range of the category.
Third-Party Tested Options Available
For athletes who compete under anti-doping regulations, Informed Choice certification matters. Clear Whey Protein Powder carries Informed Choice accreditation — independently batch-tested to give you confidence in what you're putting into your body, with none of the guesswork.

FAQs
What is protein isolate?
Protein isolate is a highly refined form of protein powder produced by filtering out the majority of fats, carbohydrates, and lactose from the protein source. The result is a product with a higher protein concentration per gram than standard protein concentrates. Whey isolate, soy isolate, and pea isolate are among the most common types available. Protein contributes to the growth and maintenance of muscle mass1.
What is the difference between whey protein isolate powder and whey concentrate?
Whey protein isolate powder undergoes more extensive filtration than whey concentrate, which removes a greater proportion of fats and carbohydrates and typically results in a higher protein percentage per serving. Whey concentrate usually sits around 70–80% protein by weight, while whey isolate is generally 90% or above.
The practical difference depends on your goals. If you're tracking macros closely or prefer a leaner supplement, isolate gives you more protein with fewer additional calories. Concentrate is a solid option when you're less concerned with that level of precision.
What is the best protein isolate for someone who wants maximum protein per serving?
Impact Whey Isolate Powder is worth looking at first — it delivers up to 26g of protein per serving with an ultra-high protein content, making it one of the most concentrated options in the range. If you prefer something lighter in texture, Clear Whey Protein Powder provides 20g of protein per serving from hydrolysed whey protein isolate in a clear, juice-style format rather than a traditional milky shake.
Is protein isolate suitable for plant-based diets?
Several options in the range are suitable for plant-based diets. Impact Vegan Protein, Impact Pea Protein, Soy Protein Isolate, and Clear Vegan Protein all offer isolate or isolate-adjacent formats without animal-derived ingredients. The breadth of plant-based options means you don't have to compromise on protein quality or format preference if you're avoiding dairy or animal products.
Is protein isolate suitable for people who are lactose-sensitive?
Whey isolate is generally considered more suitable for lactose-sensitive individuals than whey concentrate, because the filtration process removes much of the lactose along with the fat and carbohydrates. That said, tolerance varies between individuals. Plant-based isolates — such as pea or soy isolate — are naturally free from lactose and dairy entirely, making them a straightforward alternative.
What formats does protein isolate come in?
The range spans several distinct formats. Traditional shake-style powders are available, including Impact Whey Isolate Powder. Clear, juice-style powders made from hydrolysed whey protein isolate — like Clear Whey Protein Powder — offer a light, fruity alternative. There's also a hybrid option in Clear Whey Protein + Collagen, which combines 21g of protein per serving with 10g of bovine collagen peptides. Samples and variety packs are available if you want to try before committing to a full-size bag.
Who developed the protein isolate products at Myprotein?
Myprotein's expert nutritionists developed the protein isolate range, working to balance high protein concentration with great taste and mixability across both animal-based and plant-based options.
Is Clear Whey Protein Powder Informed Choice certified?
Clear Whey Protein Powder is Informed Choice certified, meaning it's independently batch-tested by a third-party organisation to verify that it's free from substances banned in sport. This is particularly relevant for competitive athletes who need assurance that their supplements meet anti-doping standards. The certification applies to the product as tested — always check the current label for the most up-to-date accreditation status.
How much protein isolate should I take per day?
Total daily protein needs vary depending on body weight, training intensity, and overall diet. Protein isolate can be used to top up dietary protein from whole foods rather than replace it entirely. A single serving — typically one scoop — is the standard starting point, and many people take one to two servings per day depending on how much protein they're getting from meals. Looking at your overall daily protein intake across food and supplements together gives you the clearest picture.
Does protein isolate only come in powder form?
The protein isolate range is primarily powder-based, but the format of those powders varies quite a bit. Beyond traditional shakes, clear protein formats mix up to resemble a fruit drink rather than a milky shake — a texture that suits people who find conventional protein shakes heavy or filling. Variety packs and sample sizes are also available, making it easy to find a format and flavour that works for you before buying in bulk.
