Casein Powder Buyer’s Guide

The Best Casein Powder: OPTIMUM NUTRITION GOLD STANDARD Micellar Casein Protein Powder

This is a gold standard supplement that is slow-release. It contains high levels of casein and has a good amino acid profile.

When Should I Take Casein Protein?

Casein can be taken at any time during the day, but it is recommended that you take it in between meals as it can act as an appetite suppressor. This is why it is ideal for weight loss.

The best time to take casein protein is actually before sleep. Most of the products in this review are slow-release and contain amino acids. When they are taken at night, the protein and acids will work together to repair your muscles and make them bigger.

Taking casein before sleep gives it plenty of uninterrupted time to get to work. This is also the time when our body naturally repairs itself and casein can really improve this process.

Casein Vs. Whey

It is important to note that both of these protein supplements are derived from milk. They can also both be used in the same way, as in most cases, they will need to be mixed with water before they can be consumed.

Each supplement has its own benefits, so you will need to think about your long-term goals when it comes to your body and fitness in order to see which is the best one for you.

Whey protein is claimed to be better for building muscle, as it can be absorbed quicker by the body. This kind of protein also contains a higher amino acid profile.

This does not mean that casein protein is not effective at building muscle, but it does come with other benefits that it is better at than whey. This includes aiding the digestive and immune system so you will feel better and fitter. Casein is the best supplement for those who want to lose weight and gain muscle.

Both whey and casein are designed to be supplements to an already healthy, balanced and active diet.  This means that you will not see results from either of these proteins unless you are putting the work in yourself.
