Casein is the predominant type of protein found in milk. Statistically, it represents around 80% of its total protein content. It is widely used as a pre-sleep supplement for protein as it is a relatively slowly digested protein source. This allows your body to increase overnight muscle protein synthesis and helps in preventing muscle degradation while asleep.

Casein supplements are provided in two forms. The first one is the micellar form, which is milk’s natural casein form. The other is a combination of sodium, potassium, or calcium caseinates, which have the added advantage of being digested easily by the body.


However, some prefer the natural form (micellar form) of Casein over caseinates. This is due to the fact that micellar Casein has a slower digestion rate. This sustains blood amino acid concentrations during the night sleep cycle.

Now that we have learned the correct forms and usage of Casein, it is time to go deeper and do some research to find some of the best casein protein powders in the market.

FAQs on Casein Protein

Q1. Why Would You Need Protein Supplements?

It is a well-known fact that humans need protein. It is no wonder that they have introduced so many flavours and concentrations of protein powders. Protein supplements help in the upkeep of muscle and aid in muscle recovery. Since it is a slow working protein, and is best taken during the night (while sleeping), the protein has the time to spread through your body and work its magic. This is one of the few ingredients that a person of any age group and with any medical condition can ingest without undergoing any side effects (for the most part).

Q2. What Other Ingredients Do They Have Besides Protein?

Protein powders are very straightforward for the most part. The majority of them contain the said protein in different forms along with a few additives to make the whole package better. These additives can range from sugar to carbohydrates and preservatives. Most of the additives are present to increase the potency of the protein, while some of them include sugar, natural sweetener, and BCAAs that impart different flavours to these powders.
So, while additives are not particularly bad for consumers, most people prefer going for the more natural casein protein.

Q3. What Is A Protein And How Are Protein Powders Formed?

Proteins are present in muscles, bones, skin, hair, and nearly every other part of the body. They make up the enzymes that power the body’s many chemical reactions.
As we do not store these, our bodies produce them in two different ways: either from scratch or by altering others. Protein is made from twenty-plus basic building blocks called amino acids. Nine amino acids, classified as the essential amino acid, a-histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine, come from food.
Protein powders are powdered sources of plant-derived protein (soybeans, peas, rice, potatoes, or cannabis), eggs, or milk (casein or whey protein). Other ingredients such as added sugars, artificial flavorings, thickeners, vitamins, and minerals, may be included in the best casein protein powder.
