Egg Protein Powder

What is egg white protein powder?

Egg white protein powder is dried egg white (albumen), sometimes flavoured and sweetened. Some products blend egg protein with other proteins, such as whey isolate, so check the ingredients to see whether you're buying pure egg white or a mix.

The ISSN lists egg alongside whey, casein, beef and soy as intact protein supplements that can produce an anabolic response, meaning they can trigger muscle-protein building in the body. It also notes that one study using 15g of egg white protein found no strength benefit, and that 15g is considered by many a sub-optimal dose; the ISSN's general guide is 20 to 40g of protein per serving.

Is egg protein dairy-free?

Pure egg white protein contains no milk, but blends may. One product in this collection combines egg with whey isolate, which comes from milk, so it isn't dairy-free.

Eggs and milk are both among the 14 allergens that must be emphasised in the ingredients list, and the NHS lists eggs and cows' milk among the most common allergic foods. If you have an egg allergy, egg protein isn't for you; if you avoid dairy, read the ingredients and "may contain" warning on each tub.

How do you compare egg protein on value?

Compare the cost per 25g of protein, because protein content per 100g differs between pure egg white and blends.

How to compare value (example figures, not real products): a £24 bag of 1kg at 80% protein contains 800g of protein, or 32 portions of 25g, so it costs 75p per 25g. A £20 bag of 500g at 75% protein contains 375g, or 15 portions, about £1.33 per 25g. Our protein powder hub explains the same method for every type.
