You are starting out in the gym and wondering which whey to choose as a beginner? Good news: you do not need a complicated or wildly expensive product. A good beginner’s whey comes down to three criteria: a short ingredient list, digestion without bloating and a sensible price. Here is our selection, followed by the mistakes to avoid.

🤔 Do you really need whey when you are starting out?

Whey is not compulsory: it is simply a convenient way of hitting your protein needs. For someone who trains, the ISSN position stand (International Society of Sports Nutrition) recommends 1.4 to 2 g of protein per kilo of body weight per day. For a 70 kg person, that works out at roughly 100 to 140 g a day.

If your diet (meat, fish, eggs, dairy, pulses) already gets you there, whey is just a bonus. If you struggle to get there, a shaker after your session or at breakfast makes life easier. To find out what it really does (and what it does not), read our guide to what whey protein does.

🥛 Concentrate or isolate: which one to start with?

• Whey concentrate: around 70 to 80 g of protein per 100 g. It is the cheapest, but it holds more lactose. Ideal if you digest milk well.
• Whey isolate: roughly 80 to 92 g of protein per 100 g as sold, with very little lactose. The right choice if milk leaves you bloated.
• Native whey: cold-filtered straight from milk, so its proteins are not denatured. Often sold as an isolate, and a little dearer.

Hydrolysed whey holds no particular interest for a beginner: it costs more for a benefit you will not notice at your level. To go further, read our comparison of whey isolate vs standard whey.

Nutripure Whey Isolate Native	★★★★★	★★★★★	★★★☆☆	★★★☆☆	4/5

1. Nutripure Whey Isolate Native: the best choice on quality

86.8 g of protein per 100 g as sold (94 g on a dry basis), and only two ingredients in the unflavoured version: French milk isolate and sunflower lecithin. A 30 g serving brings 26 g of protein for 115 kcal, with less than 0.2% lactose. Budget around €47 per kilo on the large formats (checked in October 2026), or €44.90 for the 750 g pouch if you just want to try it; the brand ships from France.

This is our recommendation if you want to start straight away with a clean product that goes down easily. The unflavoured version (a faint milky taste) also stirs into a yoghurt or a bowl of porridge; if you want a treat of a shake, go for a flavoured version instead.

2. Decathlon Whey Protein: the best budget buy in store

To try whey without spending much, Decathlon’s Whey Protein costs €34.99 for 900 g (checked in October 2026 on the Decathlon Pro shop), which is around €39 per kilo. It is a whey concentrate: 70 g of protein per 100 g and 21 g per 30 g serving, sweetened with stevia, made in France from European Union whey proteins.

Its real strength is that you can buy it in store, with no online order. It does, on the other hand, contain more carbs (17 g per 100 g, of which 8 g sugars) than an isolate, and an isolate version exists for sensitive stomachs. Our full review of the Decathlon whey sets out the differences between the ranges.

3. MyProtein Impact Whey: the widest choice of flavours

A whey concentrate (72 g of protein per 100 g, 22 g per 30 g serving) available in dozens of flavours and often on offer: around €38 per kilo when the 2.5 kg format is discounted (checked in October 2026). Handy if flavour is what will keep you going in the long run. It is sweetened with sucralose, and its lactose can upset sensitive stomachs. See also our ranking of the best MyProtein flavours.

🕒 How much whey, and when, when you are starting out?

A dose of 20 to 40 g of protein per serving is enough, which usually means one shaker made with 30 g of powder. What matters most is your protein total across the day rather than the exact time of your shake: before or after training, both work. Our guides to how much whey per day and when to take whey set out the sums, and how to take whey explains the preparation step by step.

⚠️ The classic beginner mistakes

• Replacing meals with shakes: whey tops up your diet, it does not replace it.
• Taking far too much of it: beyond your needs, extra protein does not build extra muscle. For strength athletes, ANSES advises not going over 2.5 g of protein per kilo per day, and for six months at most.
• Choosing on the marketing: look at the protein content per 100 g as sold, the ingredient list and the price per kilo.
• Buying a big tub straight away: start with a small format to check the taste and the digestion before moving up to the large one, which is cheaper per kilo.
• Confusing lactose intolerance with milk allergy: an isolate helps if you are intolerant, but not if you are allergic to milk proteins.

💬 Our verdict: which whey to start with?

To get started, a whey concentrate is enough if you digest milk well, and an isolate if you do not. Aim for 20 to 40 g per serving, keep an eye on your protein total for the day, and favour a product with a simple formula. If you would rather not think about it at all, the unflavoured Nutripure ticks every box; if budget comes first, Decathlon or MyProtein do the job perfectly well.

This selection is not for you if your diet already covers your protein needs: in that case there is no point buying whey at all. Still unsure which type of whey? Our guide on which whey protein to choose helps you make the call.
