Protein

Every protein product we sell in one place: protein powders, protein bars and snacks, and mass gainers. It is the quickest way to compare formats side by side, then narrow down by brand, flavour, diet or format using the filters.

Most people start with a protein powder, the most flexible and usually the lowest cost per gram of protein. Whey concentrate is the everyday choice, whey isolate is filtered further for a higher protein share, and vegan blends use pea, rice or soya protein. Protein bars and snacks trade some value for convenience and taste, and are easiest to carry. Mass gainers add a large dose of carbohydrate to the protein for anyone who struggles to eat enough calories. Protein contributes to a growth in muscle mass and to the maintenance of muscle mass, but the total you eat across the day matters more than the format.

How to compare protein products

  • Protein per serving: compare grams of protein per scoop, bar or shake on the nutrition panel.
  • Cost per serving: larger tubs usually cost less per serving than small tubs or single bars.
  • Sugar and calories: bars and gainers vary widely, so check both if you are watching your intake.
  • Diet: use the Diet filter or the vegan protein range if you avoid dairy.

FAQs

Which is better, protein powder or protein bars?

Powder usually gives more protein for your money and is easy to adjust. Bars are more convenient and taste more like a snack, but many contain more sugar or fat. Many people use powder at home and keep a bar in the bag.

How much protein do I need a day?

It depends on your body weight, training and goals. Our guide on how much protein you need per day explains the common grams-per-kilo ranges and easy ways to reach them from food first.

What is the difference between whey concentrate and whey isolate?

Isolate is filtered further than concentrate, so it usually has a higher share of protein and less fat, carbohydrate and lactose per scoop. Concentrate is typically cheaper per serving.

Do I need a mass gainer or just protein powder?

If you already eat enough calories, protein powder is usually enough. A mass gainer suits people who find it hard to eat enough to gain weight, because it adds a large amount of carbohydrate and calories per serving.
