Casein Protein: The 7 Best Casein Protein Powders in 2019

casein protein powder

What is Casein Protein?

There are two main categories of protein extracted from cow’s milk, Whey protein, and Micellar Casein protein, or just casein.

Both products can be reduced into a powder form without compromising the integrity, are beneficial to overall health, and have uniquely different properties and functions.

Of particular interest though, is casein protein powder.

Unlike its whey counterpart, casein is a very slow releasing protein due to its slow digestion rate.

Both can be taken pre or post workout and are very high in naturally occurring amino acids.

What are the benefits of Casein Protein?

Casein protein powder has typically taken a backseat to whey protein powder likely because it is not fast acting and most benefits are behind the scenes so to speak.

It is vital to muscle building and should be a main component of the protein profile.

Following is a list of some of the main benefits:

  • Slow 24/7 Release

Casein protein powder has a built-in mechanism which slowly releases amino acids into the blood stream, having the effect of repairing and re-building muscles during down times between workouts and while sleeping.

Muscle building activity does not occur during the workout, but rather, between workouts.

  • Better Results

Studies have shown that taking a combination of casein protein and whey protein together has a much greater effect on building lean muscle mass that using each separately.

Therefore, it is safe to say that a protein complex should be consideration for those looking to maximize the addition of muscle mass.

  • Increased Metabolism

First, proteins in general have the effect of making people feel full for long periods of time.

In addition, casein protein powder, has the added effect of increasing metabolic rate meaning that it burns fat faster reducing in weight loss.

Therefore, the combination of increased satiety levels and increased metabolism make casein protein powder a perfect supplement for those looking to build muscle mass while burning fat.

  • Anti-Catabolic Properties

The term catabolic in nutrition refers to the deterioration of muscle.

This can happen after a workout if muscles are not provided the proper nutrient to allow the muscle to repair and recovery.

During sleep is a prime time for this to happen as the body is not fed nutrients for 7 – 9 hours.

So often body builders go to bed feeling pumped only to wake up feeling that the gains they made the previous day are gone.

Casein protein powder is often called the sleep formula due to its slow release anti-catabolic properties.

During the night, a casein protein powder taken earlier in the day is still working to build the muscle mass.
