First Decision
Whey Concentrate vs Whey Isolate
Before choosing between Myprotein and Bulk, decide which type of whey makes more sense for your goals and budget.

The straightforward everyday option. Concentrate provides high-quality whey protein while retaining slightly more carbohydrate, fat and lactose than isolate.
- Usually better value
- Ideal for general training
- High-quality complete protein
- Wide flavour selection
- Easy everyday shake
Whey Protein Isolate
Whey isolate undergoes additional filtration, producing a higher proportion of protein with generally less fat, carbohydrate and lactose than concentrate.
- Higher protein concentration
- Lower fat and carbohydrate
- More highly refined
- Useful when tracking macros closely
- Typically more expensive
Brand Bing Top Picks
Myprotein vs Bulk Whey Protein
Both brands offer strong concentrate and isolate options. Here’s how we would approach the choice.
★ Best Overall Range
Myprotein Whey
Impact Whey Protein and Impact Whey Isolate.
Myprotein gives you a very simple upgrade path. Start with Impact Whey Protein if you want a conventional whey concentrate, or move to Impact Whey Isolate if you prefer a more highly filtered powder with a greater proportion of protein.
- Impact Whey Protein
- Impact Whey Isolate
- Large flavour selection
- Multiple pack sizes
- Up to 26g protein in isolate
- Sports-focused range
Our concentrate pick
Impact Whey Protein is the straightforward
all-round choice. Myprotein currently lists
around 21g protein per serving on the referenced
standard flavoured product.
Our isolate pick
Impact Whey Isolate currently delivers up to
26g protein per serving and is positioned as
lower in fat and sugar than standard whey.
Check before buying
Nutritional values vary between flavours,
so compare the exact product label rather
than assuming every version has identical macros.
★ Strong Alternative
Bulk Whey
Pure Whey Protein and Pure Whey Isolate.
Bulk offers the same basic decision: conventional whey for everyday use, or isolate when you want a more refined whey powder. Its current whey category contains numerous concentrate and isolate products across different pack sizes and flavours.
- Pure Whey Protein
- Pure Whey Isolate
- Multiple flavour choices
- Several pack sizes
- Up to 26g protein isolate options
- Large whey selection
Our concentrate pick
Pure Whey Protein is Bulk’s familiar
everyday whey option, with current variants
generally sitting in the low-20g range
of protein per serving.
Our isolate pick
Pure Whey Isolate is Bulk’s more refined
option, with current products providing
up to 26g protein per serving depending
on flavour and formulation.
Check before buying
Bulk runs frequent promotions and carries
several whey formulations, so compare
protein content and cost per serving rather
than relying only on the sale percentage.

Buying Guide
What to Compare Before Buying Whey Protein
Brand Bing Tip
Don’t automatically pay more for isolate. If standard whey already fits your calorie, protein and dietary requirements, concentrate may offer better value.
1. Protein per Serving
Check the grams of protein in the actual serving size rather than comparing only the percentage printed on the front of the bag.
2. Calories
Isolates often provide slightly more protein relative to total calories, which may matter if you’re tracking energy intake closely.
3. Fat & Carbohydrate
Whey concentrate retains more non-protein components, while isolate undergoes additional filtration to reduce them.
4. Lactose
Isolate generally contains less lactose than concentrate because of the extra filtration, although individual tolerance varies.
5. Cost per Serving
Compare the final price after discounts with the number of servings in the bag. Large percentage sales do not always equal the lowest cost per shake.
6. Flavour
Both brands offer extensive flavour choices. Nutrition values can differ slightly between flavours, so check the exact version you buy.
7. Ingredients & Allergens
Whey comes from milk. Always review the ingredient and allergen information on the current product label before purchasing.
Concentrate for value. Isolate for refinement.
Start with Myprotein Impact Whey or Bulk Pure Whey if you want a straightforward everyday protein. Move to Myprotein Impact Whey Isolate or Bulk Pure Whey Isolate when you want a higher protein concentration with fewer non-protein extras.
Frequently Asked Questions
Whey Protein Questions
What is the best whey protein powder?
There is no single best whey powder for everyone. Standard whey concentrate usually offers better value, while whey isolate is more highly filtered and generally contains a higher proportion of protein.
What is the difference between whey concentrate and isolate?
Whey isolate undergoes additional filtration that removes more fat, carbohydrate and lactose. This generally produces a higher percentage of protein than standard whey concentrate.
Is whey isolate better than whey concentrate?
Not automatically. Isolate can be useful when higher protein concentration and fewer calories from fat or carbohydrate matter to you. Concentrate is often perfectly suitable for general protein supplementation.
Which is better: Myprotein or Bulk whey?
Both offer established whey concentrate and isolate ranges. Myprotein has a particularly broad Impact lineup, while Bulk provides multiple whey formulations and pack sizes. Price, flavour and nutrition should decide the final choice.
How much protein is in Myprotein Impact Whey?
The current standard Impact Whey product provides around 21g of protein per serving on the referenced flavour, while Myprotein states that some variants can provide up to 23g.
How much protein is in whey isolate?
Both Myprotein and Bulk currently offer isolate products providing up to around 26g of protein per serving, although exact values vary by product and flavour.
Do I need whey protein to build muscle?
No. Whey powder is simply a convenient protein source. Your overall diet, resistance training, recovery and total protein intake are more important than whether the protein comes from a supplement.
