Egg white protein
Useful mainly for people needing a complete, dairy-free, fat- and lactose-free protein to meet intake or support muscle.
Quick decision guide
May help most
people needing a complete, dairy-free, fat- and lactose-free protein to meet intake or support muscle
Common dosing range
20–30 g powder (≈18–25 g protein) per serving
When to expect effects
Weeks (for training adaptations)
Watch out for
egg allergy — must avoid entirely; reactions can be severe
What is it
Egg white protein is derived from the albumen (white) of chicken eggs, dehydrated and powdered for supplement use. It provides a complete, highly bioavailable protein with one of the best amino acid scores of any food protein.

muscle protein synthesis and lean mass with resistance training
Supplement benefitMeta-analyses of protein supplementation show that adequate high-quality protein augments gains in muscle mass and strength during resistance training. Egg white is a complete protein with a PDCAAS of 1.0 and substantial leucine, so it supports muscle protein synthesis comparably to other quality proteins. The benefit comes from meeting total protein needs rather than anything unique to egg white.
Bottom line: A top-quality protein that reliably supports muscle when it helps you reach adequate intake.
dairy-free / lactose-free complete protein source
Mechanism onlyEgg white protein provides all essential amino acids in sufficient amounts (biological value ~100) while being free of lactose, dairy, fat, and cholesterol. This makes it a practical complete-protein option for people who cannot or prefer not to use dairy-based powders. Pasteurized commercial powder avoids the Salmonella and biotin-binding concerns of raw egg white.
Bottom line: A genuinely complete protein for those who need to avoid dairy or fat.
How it works
How to take it
What to track
3 commercial forms
Compare the main delivery options and what they’re best suited for.
Egg white protein powder
Standard supplement form. Typically unflavored or flavored, with very low fat and carbohydrate content. Mixes into shakes and recipes.
Pasteurized, dehydrated egg whites; high purity protein.
Liquid pasteurized egg whites
Carton liquid egg whites available in grocery stores. Can be cooked, drunk after pasteurization, or used in shakes. Less concentrated than powder per volume.
Whole-food form; pasteurized for safety.
Whole eggs
Eating whole eggs provides additional nutrients beyond protein, including vitamin D, B12, choline, and lutein. Recent research suggests whole eggs may support muscle protein synthesis better than equivalent egg whites alone.
Provides yolk nutrients (fat-soluble vitamins, choline) along with protein.
Safety
Know the common side effects, key cautions, and who should avoid it.
Common side effects
Serious risks
severe allergic reaction in people with egg allergy
Who should avoid it
- anyone with egg allergy
- vegans (egg-derived)
- those advised to restrict protein in kidney disease
Pregnancy & breastfeeding
Pasteurized egg white protein is acceptable as a food protein in pregnancy unless egg-allergic; raw egg white must be avoided.
Interactions
like any protein, may modestly slow absorption of some drugs taken concurrently

Frequently asked questions
Is egg white protein better than whey?⌄
Both are high-quality complete proteins with similar PDCAAS scores. Whey digests faster and has higher leucine per gram. Egg white digests at an intermediate rate. The 'better' choice depends on dietary restrictions and preferences.
Can I drink raw egg whites?⌄
No. Raw egg whites can carry Salmonella, causing food poisoning. They also contain avidin, which binds biotin and can lead to deficiency over time. Use only pasteurized egg whites or commercial egg white protein powders.
Does egg white protein contain cholesterol?⌄
No. All cholesterol in eggs is in the yolk. Egg white protein is essentially cholesterol-free and very low in fat.
Why is egg white protein often more expensive than whey?⌄
Production costs are higher because pasteurization, drying, and processing of egg whites is more complex than whey, which is a byproduct of cheese making. The price reflects production economics rather than nutritional superiority.
Will egg white protein work post-workout?⌄
Yes. With 20 to 30 g per serving, egg white protein provides sufficient leucine and total protein to support post-workout muscle protein synthesis.
