Regardless of the plethora of protein powders available on the market these days, most folk go for whey or casein.

There’s motive for this: specialists and research virtually unanimously agree they’re the best protein dietary supplements for supporting muscle development.

There’s much less consensus, nevertheless, on the subject of which of those two is greatest.

Some say whey is the most effective protein for constructing muscle as a result of it causes a speedy spike in amino acid ranges within the blood (the “constructing blocks” of protein), which helps you construct muscle sooner.

Others declare casein is the true winner as a result of it’s a “slower-burning” protein, retaining your amino acid ranges elevated for for much longer than whey, which ends up in extra muscle development over time. 

Who’s proper?

On this article, we’re going to have a look at what science says in regards to the deserves of casein vs. whey protein, so you may resolve which is greatest for you.

What Are Casein and Whey Protein Powder?

Cow’s milk incorporates two sorts of protein: casein and whey (80% casein and 20% whey).

Complement producers extract each of those proteins and course of them into powder which they promote as protein dietary supplements.

Each are in style amongst weightlifters as a result of they include all of the important amino acids (amino acids your physique should get from meals), and they’re wealthy within the amino acid leucine, which performs a significant function in initiating muscle protein synthesis (MPS).







What’s the Distinction Between Whey and Casein?

The principle distinction between whey and casein is digestion velocity. 

Whey is acid-soluble (it dissolves in acid), so it digests shortly in your abdomen. This implies it spikes blood amino acid ranges quickly after you eat it, stimulating a speedy improve in MPS (particularly if you take it post-exercise).

When casein reaches your abdomen, it curdles within the acid, slowing its digestion. Consequently, casein doesn’t elevate blood amino acid ranges as excessive as whey protein, nevertheless it retains them elevated for longer (as much as six hours).

Right here’s a graph illustrating this level:


Leucine Appearance


Many individuals make a giant deal of this distinction, claiming whey is a greater post-workout protein as a result of it expedites the muscle-building course of, and casein is a superior pre-bed protein as a result of its “gradual launch” prevents muscle breakdown through the hours that you just’re asleep (and thus not consuming protein).

Whereas this logic appears affordable, analysis doesn’t assist it.

Research present that each sorts of protein assist muscle development equally nicely, and offered you eat sufficient complete protein all through the day, taking casein earlier than mattress provides no profit.

There are additionally a handful of minor well being advantages related to each whey and casein. 

Casein incorporates compounds which will scale back hypertension, decrease heart problems danger, and act as antioxidants.
