Best Casein Protein Powders

The 5 Best Casein Protein Powders, According to a Dietitian

If you’re a fitness enthusiast, then you probably know the importance of supplementation. Supplements are not necessarily required for results but to boost the process.

Intuitive nutrition and an effective training plan are core pillars of a smart routine but using casein protein can unlock a new level of potentiality and health.

What Is Casein Protein?

Casein is a milk-derived, slow-digesting protein often taken as a supplement. In most cases, people take it before bed to reduce muscle breakdown and speed recovery. Therefore, it’s commonly known as a recover protein rather than a pre-workout supplement. 

Casein is a great way to add the required protein content to your diet. The convenient protein is easy to mix with liquid for a high-quality protein beverage. It feeds your body with amino acid necessary to build muscles. It is also slow to digest, which makes it ideal for reducing appetite.

 Forms of Casein

Casein can be consumed in two forms:

  • Casein Hydrolysate – The protein is broken down for easy absorption and digestion.
  • Micellar Casein – This form of casein groups together into small balls known as micelles to allow it to clot in the stomach. It slows the absorption process, giving you a satiety feeling. As a result, it helps you curb your cravings and hunger pangs.

 Benefits of Casein Protein

Apart from containing essential amino acid, casein protein offers other benefits such as:

Aids in Muscle Building

Casein protein delivers a steady and sustained flow of amino acids. While sleeping, the body releases human growth hormone capable of building lean muscle mass. However, the process requires protein for synthesis. Therefore, taking your casein protein powder before bed will support this mechanism.

Promotes Faster Recovery

Hitting the gym doesn’t mean you’ll get stronger and grow muscles instantly. You need to be persistent and with proper nutrition.

Supplementation can help in muscle growth, repair, and maintenance, and casein protein is crucial in this process. Typically, the muscle fibers get damaged after a workout, and your body utilizes amino acids and protein to build and repair the muscles.

Casein supplies your body with a protein source over a couple of hours after a workout, ensuring your body is protein-positive.

Improves Fat Loss

One of the major benefits of working out is losing fat. Some studies indicate that casein protein might promote fat loss. Consuming more protein can be beneficial for dropping stubborn pounds due to controlled calorie intake.

What to Consider When Choosing Casein Protein Powder

The market is saturated with hundreds, if not thousands, of casein protein powders. This makes it hard to pick the right product for you.

However, with the right information, picking the right casein protein powder can be hassle-free.

So, what should you consider?

How much casein protein do you need?

It helps to understand why you need protein in the first place. Not getting enough casein protein can lead to loss of muscle mass, damaged muscles, mood swings, and weak bones.

If you’re a fitness enthusiast, more so in strength training, then you need to have a steady supply of casein protein powder.

Efficiency in nutrient supply

If nutritional efficiency is your aim, the casein protein powder is the ideal choice. Casein forms a gel or clot in the stomach to provide a slow but steady release of amino acids into your bloodstream for hours.

Fat and Sugar Content

Check the sugar and fat content before purchasing casein protein powder. It’s recommended to choose a product with a low-fat level and no artificial sweeteners as they may halt fitness goals. This is beneficial if you want to lose weight.

Flavor Range

Although you may want a steady supply of protein, ensure it’s palatable. Play with an array of flavors until you find what your taste buds love.

Ingredients

If you’re gluten-intolerant or have a Celiac disease, then keep off casein powders with gluten. The same goes for artificial sweeteners and soy.

Now, let’s take a look at the best casein protein powders on the market.
