7 Best Casein Protein Powders on the Market

Recently I’ve made a lot of guides regarding fitness equipment, mostly stuff for your own home gym. I realized that it has been sometime since I’ve put together another comprehensive guide about food or supplements. So I decided to great the ultimate guide for best casein protein powders on the market as of now. So without further due, let’s jump right into it.

Best Casein Protein Powders

What is Casein Protein?

Before we jump right to the actual guide, I’d like to talk a bit about Casein. What exactly is it? Casein is a phosphor-protein and it is the most abundant protein in milk. It makes from 60% to 80% of all proteins in mammalian milk and from 20% to 40% of proteins in human milk.

Since it is an abundant milk protein, naturally, it’s a major component of cheese. Particularly as a food source, it contains carbohydrates, calcium, phosphorus and essential amino acids. EAC’s cannot be created by a human body; therefore, the only possible source is from food.

Most of you know that casein protein is a slow-digesting protein, therefore should be taken before a good night’s sleep. But why is it so? What makes it so special and different from other proteins, like whey protein?

Casein vs. Whey Protein

The main difference between the two is that casein protein is mainly indissoluble and keeps forming micelles structures, which are known to increase solubility in water.

When the milk is processed, the micelles structures become fractured and tend to form simpler gelatinous structures. This is the main reason of a slower rate of digestion and thus, steadier release of essential amino acids into body circulation.

Whey protein, on the other hand, is considered a fast-digesting protein, thus, release bigger amounts of amino acids into the circulation in a shorter span of time, thus giving human body a natural burst.

Does Whey Triumph Over Casein?

In short, no, it does not. While whey does offer burst of amino acids into the body and faster increases protein synthesis, it is short lived. There have been several studies that show that the best results came from the usage of both proteins, more precisely Whey protein shortly after training and Casein protein half an hour before sleep.

With that being said, let’s dive right into our guide of best casein protein powders on the market. Several major brands are producing this kind of protein powders and we will take a closer look at the very best ones.
