Body builders, ballet dancers, cyclists and swimmers, whatever you like to do with your time, sometimes your body may need a little extra protein, and whey protein could be the one for you.


How much protein do I need in my diet?


For most of us, eating a healthy, balanced diet will provide us with enough protein – around 0.75g per kg of body weight is recommended. However, this figure changes in line with our activity levels or body goals.

For example, if you were training for a marathon (or any other endurance sporting event) and weigh 76kg, you should be getting 1.2g of protein per kg, which equates to 91.2g of protein a day. If then you finished the marathon and started to hit the gym instead with the aim to gain muscle and lose weight, you’d have to almost double your protein intake to 2.0g per kg and should be getting 152g a day.

Have a look at the table below to see the average estimate of how much protein you may need based on your lifestyle:

Activity - Amount of protein

No to little activity - 0.75g

Endurance athletes - 1.2g

Team sports - 1.5g

Muscle gain - 1.8g

Muscle gain and weight loss - 2.0g


Which protein powder is best for me?


Whey protein powder isn’t your only option when it comes to a protein supplement – there are tons of different ones out there! However, there are a few more important factors to consider when you’re making your decision. One of the most important factors is if they’re a complete (have all 9 essential amino acids) or incomplete protein (lacking 1 or more of these acids). Whey protein is a complete protein which doesn’t need to be combined with any other sources to supply you with the all-important 9 amino acids. Some incomplete proteins include rice and hemp, which can be combined to make a complete protein.


What is whey protein?


The protein in whey originates from dairy milk. To be more specific, whey is made during the process of cheese-making and is a by-product.


What are the benefits of whey protein?


Firstly, it is a complete protein, which contains all the essential amino acids aka the ‘building blocks of protein’. It is easy for the body to digest unless you have a dairy allergy. You may still be able to take it if you’re lactose intolerant – just choose whey with an added lactase enzyme or isolate whey. And perhaps the most important benefit - it encourages lean muscle growth.


Which whey protein product is the best for me?


Tough question! Have a look at the main benefits of each whey protein product we sell at Holland & Barrett below and get an idea of which one could work best for you.


Standard whey protein powder


Often contains multiple forms of protein, e.g. isolate, hydrolysed and concentrate, so is well balanced. It has a good calorie to protein ratio, so you can use it to increase muscle mass or to gain weight easily.


Diet whey protein powder


Has a lower calorie count than standard whey protein with a good amount of protein, so you can use it as an aid to weight loss or to get lean.


Whey protein bars


You can get a quick protein hit on-the-go, no shaker required! These bars are great as a filling snack or for refuelling instantly after the gym.


Ready-made protein shakes


Another great product for busy people, these shakes are perfect for rushing-out-the-house breakfasts, filling that hunger-gap in the middle of the day and drinking after the gym for an instant protein hit.

What is whey protein?


Whey protein is produced from milk. The manufacturing process removes most of the fat and milk sugars (carbohydrates) and leaves you with a convenient powder which is packed with protein and amino acids, making it very easy to add extra daily protein to your active and sporty lifestyle. Within the whey protein category there are different types of whey protein, including whey isolate which is absorbed more quickly, to casein protein which is absorbed more slowly and ideal for bedtime.


Benefits of whey protein


Whey protein is an easy and convenient way of getting extra protein into your daily diet between meals, or directly after training; simply scoop, mix and drink. You can carry it with you in your gym bag or keep a tub in your locker, car or desk. Whey protein powder can be relied on to deliver the extra protein your hard-working body needs, with no mess and no fuss.
