Whey protein: how to choose a powder to suit your training and budget

You’re looking for whey protein to top up your daily intake, but labels often start to look very similar. Between whey isolate, whey concentrate, hydrolysed whey, promises of fast absorption and value formats, it’s easy to pay more for a difference that won’t make much difference to your routine.

Before buying protein powder, three pitfalls deserve your attention:

• Relying solely on the stated protein content: a powder containing 80 g of protein per 100 g isn’t automatically right for your needs. Carbohydrates, fat, sugars, salt and the actual serving size matter too.
• Confusing composition with marketing: a whey protein can combine isolate, concentrate and hydrolysate. Having several sources isn’t a drawback, provided they’re clearly listed in the ingredients.
• Choosing a large format without trying the flavour: a bag weighing several kilos often works out cheaper per serving, but quickly becomes a wasted expense if you don’t like the texture or taste.

What to check before buying

1. The amount of protein per serving

Always compare the information for an actual serving size, rather than looking only at the values per 100 g. In the selection below, servings generally range from 28 to 32 g and provide around 21 to 24 g of protein.

For protein intended to support muscle gain, the supplement should form part of a varied diet and regular training routine. Powder doesn’t replace meals. According to labelling compliant with authorised claims in the European Union, protein contributes to the growth and maintenance of muscle mass when overall intake is appropriate.

2. The type of whey

• Whey concentrate: it retains more of the milk’s components and generally has a slightly lower protein content than isolate. It can be suitable for daily use and a controlled budget.
• Whey isolate: it is more highly filtered and often appears at the top of the ingredients list in blends. However, check the final protein content: the term ‘isolate’ alone isn’t enough to assess the whole formula.
• Hydrolysed whey: the proteins have been partially broken down. It sometimes appears in blends designed for faster absorption, although this isn’t essential for everyone who trains.

A formula combining isolate, concentrate and hydrolysate can therefore be suitable for versatile use. Remember to check the secondary ingredients too, including thickeners, sweeteners, flavourings and soya lecithin.

3. Format, flavour and allergens

Calculate the number of servings rather than comparing only the weight of the bag. A 2 kg or larger format suits regular users, while a 300 to 450 g pack lets you try chocolate or vanilla protein powder before committing.

The products featured here contain milk and, in several cases, soya lecithin. Some may also contain traces of gluten, eggs, peanuts or nuts. If you have an allergy, rely solely on the label of the product you purchase.

Everyday usage tips

Generally mix one scoop with water or milk, following the quantity stated on the packaging. Post-workout protein can be taken after a session, but also between meals when your diet doesn’t cover your needs for the day. The exact timing matters less than consistency in your total intake and maintaining a balanced diet.

Keep the bag or tub tightly closed, in a dry, cool place away from light. Observe the best-before date and don’t use the product if its appearance, smell or taste has changed.

Frequently asked questions about whey protein

How long does whey protein keep after opening?

The shelf life depends on the date provided by the manufacturer and the storage conditions. Powder kept dry, properly resealed and protected from heat will generally retain its sensory qualities for longer. Avoid bathrooms and damp places.

Is whey protein necessary for building muscle?

No. It can make it easier to increase your protein intake, but it doesn’t replace a varied diet or training. Results depend in particular on your programme, energy intake, rest and consistency.

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

Isolate is generally more highly filtered and often has a higher protein content. Concentrate may contain more lactose, carbohydrates or fat, depending on the formula. Compare the nutrition tables and ingredients list rather than relying solely on the product name.
