Protein Guide: Whey, Isolate, Casein and Plant Protein

Protein contributes to a growth in muscle mass, to the maintenance of muscle mass and to the maintenance of normal bones. Protein powders are a practical way to top up the protein in your diet, as part of a varied and balanced diet and a healthy lifestyle. On each product you will find the grams of protein per serving, full nutrition information and allergens.

Whey Concentrate: whey protein from milk, usually with 70 to 80% protein. It has a complete essential amino acid profile and is the most common and affordable form of whey, easy to mix with water or milk.

Whey Isolate: goes through an additional filtration process that reduces fat, carbohydrates and lactose, giving a higher protein content (usually above 85–90%). Isolates generally contain less lactose than concentrates, but they are not lactose-free unless stated on the label — always check the product information.

Hydrolysed Whey: whey in which the proteins have been partially broken down into smaller peptides by hydrolysis. It usually has a slightly more bitter taste and a higher price.

Casein: the other milk protein, digested more slowly than whey. It is often taken in the evening or between meals.

Plant Protein: made from pea, rice, soya or other plant sources, suitable for those following a vegan diet or avoiding milk proteins. Combining several plant sources gives a more complete amino acid profile.

Beef Protein and Bars: you will also find beef protein and protein bars for a practical option on the go.

How to choose: compare the grams of protein per serving, the sugar and fat content, the ingredients list and allergens (most milk-based proteins contain milk). Choose the type of protein that suits your dietary preferences — dairy or plant-based — and the flavour you like best.
