The best whey protein: At a glance

How to buy the best whey protein for you

What types of whey protein are there?

Whey protein is derived from milk and generally comes in three forms when it comes to fitness supplements.

The two most common are whey concentrate and whey isolate. Both are filtered, but the process is more intense with whey isolate, and as a result it contains less of the milk’s fat and sugar and has a higher protein content overall. Whey isolate will generally be 90% protein, while whey concentrate, which is cheaper, is usually around 80% protein.

The third type of whey protein is hydrolysed whey, which is another very pure form of protein that is easier for the body to absorb because the protein it contains has already been partially broken down. Hydrolysed whey is the most expensive of the three common types of whey protein.

What are the different kinds available?

Whey supplements generally come in powder form, with the next most common product being protein bars containing whey.

Whey powders can be adjusted to suit different purposes. There are standard protein shakes to help repair your muscles after workouts, which are generally low in nutrients other than protein, but you’ll also find mass gainers that contain large amounts of carbohydrates and calories alongside protein to help you bulk up.

Other common products include meal replacement shakes, or weight-loss shakes, both of which can use whey to provide a large amount of protein in a serving to help you feel full after consuming them.

Can I use whey protein shakes for weight loss?

Whey protein is a common ingredient in weight-loss shakes because increasing your protein intake is a good way to lower the calories you eat overall without feeling hungry, because protein has a bigger effect on satiety than other macronutrients such as carbohydrates.

This means they can help you lose weight in the short term because they enable you to get into a calorie deficit where you’re burning more than you’re consuming, However, using meal replacement or weight loss shakes is unlikely to be an effective long-term weight management option.

How much do I have to spend?

This depends largely on the quality of the whey protein you’re looking for. Cheaper whey concentrate powders start from around £10 per 1kg, with that price rising to £50 per 1kg if you’re buying more pure hydrolysed whey or whey isolate.

It’s important to look not just at the overall price of the product you’re buying, but also how many servings it contains, because that will give a better indication of how long it will last and whether you’re getting good value for your money.

What ingredients should I look out for?

Start by checking out how much protein you’re getting – a minimum of 20g per serving is expected, and this can rise to over 30g per serving. Then look at the amount of fats, carbohydrates, sugars and calories you get in a serving to make sure those numbers fit with your general dietary goals.

After you’ve ticked off those essentials, you can look out for added bonuses such as vitamins and minerals or performance-boosters like caffeine, creatine and L-carnitine.

You might also want to check on the type of sweeteners the whey powder contains, especially if you’re looking to avoid things like aspartame.

MyProtein Clear Whey IsolateThe range of flavours available with protein powders is now wider than ever, but most still build upon the classic trio of chocolate, strawberry and vanilla by offering dessert-inspired shakes. These are often pretty thick and milky too, and sometimes after a hot and sweaty workout it’s not the most enticing thing in the world.

Myprotein’s Clear Whey Isolate powder offers something different, with juicy flavours that are far more refreshing than the usual protein shake options. You can chug down a mojito or bitter lemon shake, for example, or a tropical dragonfruit one, and the range of flavours keeps on growing.

The shakes themselves are also top-notch when it comes to the fine details, with 20g of protein sourced from hydrolysed isolate per 25g serving.
