Albumin
What is it?
Albumin is a medium-digesting protein extracted from egg whites. With approximately 85% to 90% protein per serving and a complete amino acid profile, it is one of the oldest and most used protein sources in sports supplementation. Its digestion takes 3 to 4 hours — slower than Whey, faster than Casein — making it a versatile option throughout the day.
Main Benefits
- Complete and high-quality amino acid profile
- Intermediate absorption speed — ideal between meals
- Lactose-free — great option for intolerant individuals
- High protein content per serving
- Good satiety
- Natural option with no dairy derivatives
Who it's for
- •People with lactose intolerance
- •Practitioners looking for a natural protein without dairy derivatives
- •Those seeking an intermediate-absorption protein for use throughout the day
- •Athletes in a body definition phase
- •People who already use Whey and want to diversify protein sources
Common Dose
20g to 30g per serving. Can be consumed between meals, before bed or according to daily protein needs.
How to Choose
Choose Albumin if you are lactose intolerant or prefer to avoid dairy derivatives, but still want a high-quality protein. It is also a good choice for those who already use Whey and want to diversify protein sources throughout the day — its intermediate absorption makes it ideal for meals where the next eating window is further away. If the goal is to maximize immediate post-workout protein synthesis, Whey is still more indicated due to faster absorption.
What the Science Says
Egg albumin (ovalbumin) has a high biological value and a complete essential amino acid profile. Studies show that egg protein is comparable to Whey in terms of stimulating muscle protein synthesis, especially when consumed in adequate amounts. Its intermediate absorption speed makes it effective for use throughout the day, particularly in meals where the gap until the next meal will be longer.
Possible Side Effects
Generally well tolerated. People with egg allergies should avoid it. May cause gastrointestinal discomfort at high doses. The characteristic smell of the product may be unpleasant for some.
Final Summary
Albumin is an excellent option for those seeking a natural, lactose-free protein with intermediate absorption. Ideal for use between meals or as a complement to Whey in more complete protein strategies. Although less popular than Whey, it delivers equivalent protein quality with the advantage of being dairy-free.
