BONUS – Kaged Casein Protein

Kaged Casein Protein emerges as a noteworthy player in the realm of protein supplements, particularly due to its emphasis on casein, a slow-digesting protein with unique properties and benefits.

Kaged derives its protein content primarily from micellar casein, a high-quality form of casein known for its slow digestion rate. Micellar casein forms micelles in the stomach, creating a gel-like structure that slows down the release of amino acids into the bloodstream. This gradual release provides a sustained elevation of amino acids over an extended period, making Kaged Casein an optimal choice for individuals seeking a protein source that offers prolonged muscle protein synthesis and satiety.

The use of micellar casein in Kaged is advantageous not only for its time-release properties but also for its rich amino acid profile. Casein is particularly abundant in essential amino acids, including leucine, isoleucine, and valine. Leucine, in particular, is a key trigger for muscle protein synthesis, making Kaged Casein a strategic choice for individuals aiming to support muscle recovery and growth during periods of rest, such as overnight.

Beyond its protein composition, Kaged sets itself apart by its commitment to quality. The product undergoes a microfiltration process to preserve the integrity of the protein and remove impurities. This ensures that consumers receive a product with high protein content and minimal contaminants, aligning with the expectations of those prioritizing product purity.

Additionally, Kaged integrates digestive enzymes into its formula, specifically protease enzymes. These enzymes assist in breaking down the protein into smaller peptides and amino acids, facilitating absorption and reducing the likelihood of gastrointestinal discomfort. This attention to digestive support enhances the overall bioavailability of the protein content, a thoughtful touch in the formulation.

It’s important to note that the suitability of Kaged may vary based on individual dietary preferences and health considerations. Those with lactose intolerance or specific dietary restrictions should assess the product’s compatibility with their needs. In summary, Kaged Casein Protein stands as a scientifically formulated supplement, leveraging the unique properties of micellar casein to provide a sustained release of amino acids, supporting muscle health and recovery.

What Are the Benefits and Side Effects of Casein Protein?

Casein protein is an animal-based protein. This means it might not be ideal for you if you are trying to follow a plant-based diet. That said, it doesn’t discount the fact that casein is relatively safe for humans to take. That said, you will be able to reap the full benefits of casein protein just like any other protein.

These benefits include:

  • Weight loss due to fat loss
  • Gaining lean muscle and muscle mass
  • Increased protein synthesis
  • Slower intestinal motility which prolongs its effects
  • Helps relieve stress
  • Curbs the appetite and keeps you full
  • Improves the quality of your sleep
  • Helps build strength when taken in conjunction with resistance exercises
  • Increases your strength
  • Can reduce enamel erosion
  • Can help with colon health

There are certainly many advantages to taking casein powder over whey powder. That said, you should be careful when taking casein. Casein is animal-based and does not contain lactose. That said, even if you aren’t lactose intolerant, you may still be allergic to Casein. It’s best to make sure you contact your physician to make sure.

Furthermore, one should always be careful about taking too much Casein. It is proper practice to make sure you are not going over your requirement every day, especially if you aren’t very athletic and active.

Side Effects of Casein Protein

Take a look at some of the more minor side influence of taking excessive amounts of Casein:

  • Nausea
  • Bloated feeling
  • Headaches
  • Digestive distress like diarrhea or gassiness

Moreover, there is more major and life-threatening side influence for people who are allergic to Casein. It is also not recommended for women who are lactating and pregnant. That said, there aren’t enough studies to support the speculations, but it is never too hard to stay on the safe side.

Take a look at the most common side influence of an allergic reaction to Casein:

  • Swelling in the lip, tongue, throat or face area
  • Adverse skin reactions or irritations. You might notice the presence of rashes, red and itchy skin or hives.
  • Congested nasal passages, runny nose, sneezing, itchy eyes, coughing, and wheezing
  • Anaphylaxis

Summary: There are many benefits unique to Casein when compared to whey protein. That said, while there are not that many clinical studies supporting the theories that Casein may cause more severe problems when taken incorrectly, it;s still best to make sure you are not going over your daily requirement. When in doubt, consult a doctor.

Frequently Asked Questions

Which is Better Whey or Casein Protein?

It depends on your needs. Whey protein is generally the first choice since it is better for building muscles, easier to take, and, more often than not, tastes better than Casein.

Versus Whey

That said, Casein is better at preventing muscle breakdown. So the best option would be to take a combination of both protein sources.

Should I Drink Casein Every Night?

Though research. If you are trying to gain muscle mass and increase your body’s response to resistance exercise, then yes. Drinking Casein powder before bed can also improve the quality of your sleep. That said, you need to make sure you are not taking too many casein smoothies throughout the day.

The American College of Sports Medicine, the American Dietetic Association, and the Dietitians of Canada also recommend that athletes consume between 1.2 and 1.7 g of protein per kg.

Is Casein Linked to Cancer?

There are certainly no proven or accepted in the medical field. That said, there are many studies claiming that milk (they get separated in the cheesemaking process) and dairy products are linked to cancer.

I recommend that you take everything in moderation. After all, despite claims against dairy products, human beings have been consuming dairy for over a hundred years.

Note: We do not recommend buying and taking any supplements featured on this website without speaking with a doctor first.

Should I Mix Whey and Casein?

We recently asked some supplement industry experts about the many choices available to consumers. The answers vary from “it depends” to “you should get it from the health food store.” Here are some of their comments. There are some studies that suggest the benefits of whey protein are larger than those of casein protein, but they also seem to suggest that the higher the proportion of whey protein, the more benefits to the body. This is hard to believe when you consider that 70% of the people who look at protein grams are really concerned about the amount of protein they consume. It doesn’t carry the same baggage as dairy products or casein protein. I think the most practical way for people to take care of their health is by eating whole foods, and by avoiding supplements that are not approved for use in the USA.

Whey can easily be mixed with other protein supplements. Since casein is a milk protein, it is soluble in water. WHEY is not soluble in water. It has to be hydrolyzed, which breaks the protein apart before it can be absorbed. This is done by the body, and hydrolyzed proteins are digested much more slowly than those that are not hydrolyzed. It would be interesting to find out if this difference in the digestibility of casein protein might actually be related to the lesser effect that casein has on the body. In any case, it is easier for protein to be absorbed when it is mixed with another protein. I use WheyPro Gold as a base for any other protein that I mix with it. There are protein powders that are totally non-digestible, and there are others that need to be hydrolyzed prior to being absorbed.

Casein Protein Dangers

Let’s start at the top and work our way down. It occurs in cow’s milk, which most people consider a nutritious source of calcium, protein, and vitamin D. However, a study released last month by the Journal of the Academy of Nutrition and Dietetics called the quality of casein protein in human milk “unacceptably low.” This is why too many infants end up with a condition called neonatal Growth Hormone Deficiency. It’s also why adult casein protein is a concern as well. It can be metabolized to form lactose, which raises blood sugar levels in the short term. In the long run, high blood sugar levels are linked to weight gain, diabetes, and heart disease.

Dairy fat is also high in saturated fats, which are linked to heart disease and other health issues. A fat called oleic acid is the primary source of the polyunsaturated fatty acids that are at the center of a heart-healthy, ketogenic diet. There are other concerns as well. It is linked to obesity, inflammatory bowel disease, and osteoporosis. A four-ounce serving of Ben & Jerry’s offers just 1.3 grams of protein.

Why You Should Avoid Casein?

Any reasonable person who is trying to avoid casein will have to recognize that the benefits of a healthy lifestyle are almost certainly better than whatever all-casein foods you can get your hands on. Casein is a protein found in milk, whey, casein hydrolysate, cheese, yogurt, and many other foods. Whey, casein hydrolysate, yogurt, and cheese are low-quality casein products and are usually used to fuel hard-core weight lifting and bodybuilding programs.

Of course, casein is not just limited to milk products. Dairy products have a significant influence on cholesterol levels in the body. Studies have shown that consuming 1,000 calories or more of high-fat dairy foods on a regular basis will cause a spike in cholesterol levels. The problem is that this amount of cholesterol increases to an even higher amount.

Is Casein Protein a Hoax?

There are a lot of soy-based dietary supplements, including liquid, powdered and granular forms, but liquid protein products containing casein protein are few. It is derived from dairy. The first natural form of casein was created by the bacteria Escherichia coli, according to Wikipedia. It is derived from milk and is the main protein component of milk. So, milk is not natural, but if you need extra protein, this protein has been derived from milk.

Organic casein protein is found in flaxseed. If you are considering protein from a plant-based source, try flaxseed instead of whey. According to Healthline, you can take up to two tablespoons of plain, ground flaxseed for breakfast and use this seed as a substitute for meat and dairy protein for at least six months to begin to see improvements in metabolic health. To use flaxseed in a protein supplement form, grind a few tablespoons of ground flaxseed and take it as a supplement. According to the National Institutes of Health, a protein that is derived from milk or eggs is naturally very high in protein, but there are a few drawbacks to casein protein.

Which is Better Casein or Whey Protein?

The question of whether casein or whey protein is better depends on various factors, including individual goals, dietary preferences, and timing of consumption. Both casein and whey protein offer unique benefits and can be valuable additions to a well-rounded nutrition plan.

Casein protein and whey protein are two types of protein derived from milk, but they differ in their composition and digestion rates. Casein protein constitutes about 80% of the protein found in milk, while whey protein makes up the remaining 20%.

Casein protein is characterized by its slow digestion rate, forming a gel-like substance in the stomach that slows down the release of amino acids into the bloodstream. This prolonged release of amino acids makes casein protein an excellent option for promoting satiety and providing a sustained source of protein over an extended period, such as between meals or before bedtime. Additionally, casein protein contains high levels of the amino acid glutamine, which plays a vital role in immune function and muscle recovery.

On the other hand, whey protein is known for its rapid digestion and absorption, resulting in a quick spike in amino acid levels in the bloodstream. This makes whey protein an ideal choice for post-workout nutrition, as it can quickly deliver amino acids to muscles, promoting muscle protein synthesis and recovery. Whey protein is also rich in branched-chain amino acids (BCAAs), particularly leucine, which is crucial for stimulating muscle protein synthesis and supporting muscle growth.

In terms of muscle-building potential, both casein and whey protein have been shown to effectively support muscle protein synthesis when consumed as part of a balanced diet and resistance training program. However, whey protein may have a slight edge in promoting muscle protein synthesis due to its faster digestion rate and higher leucine content.

Ultimately, the choice between casein and whey protein depends on individual preferences, dietary restrictions, and specific goals. For individuals looking to increase protein intake throughout the day or promote satiety, casein protein may be a better option. Conversely, those seeking rapid muscle recovery and growth, particularly around workouts, may benefit more from whey protein. It’s essential to consider your unique needs and consult with a healthcare professional or registered dietitian to determine the most suitable protein source for you.

Frequently Asked Questions

Should I Take Casein Protein Every Night?

Casein protein, a slow-digesting dairy protein, has become a popular supplement among fitness enthusiasts and athletes for its potential benefits in muscle recovery and growth. This article explores whether taking casein protein every night is beneficial and what scientific evidence supports this practice.

Understanding Casein Protein

Casein protein is derived from milk and makes up about 80% of the protein content in cow’s milk. It forms a gel-like substance in the stomach, which slows its digestion and the release of amino acids into the bloodstream. This slow-release property makes casein an ideal protein to consume before periods of prolonged fasting, such as overnight sleep.

Benefits of Nighttime Casein Protein

Enhanced Muscle Recovery: During sleep, the body undergoes repair and growth processes. Consuming casein protein before bed provides a steady supply of amino acids, particularly leucine, which is crucial for muscle protein synthesis. Studies have shown that nighttime casein intake can enhance muscle recovery and growth, especially when combined with resistance training.

Prevention of Muscle Breakdown: The slow digestion of casein helps prevent muscle protein breakdown. This is particularly important overnight when the body goes without food for several hours. By maintaining a positive protein balance, casein can help preserve muscle mass.

Improved Satiety: Casein’s slow digestion can also help with satiety, potentially reducing nighttime hunger and preventing unhealthy snacking. This can be beneficial for those looking to manage their weight or avoid excess calorie intake.

Scientific Evidence

Research supports the benefits of casein protein consumption at night. A study published in the “Medicine & Science in Sports & Exercise” journal found that athletes who consumed casein protein before bed experienced greater muscle strength and size gains compared to those who did not. Another study in the “British Journal of Nutrition” demonstrated that nighttime casein consumption increased muscle protein synthesis rates and improved overall recovery.

Practical Recommendations

For optimal benefits, consider taking 20-40 grams of casein protein approximately 30 minutes before bedtime. This can be in the form of a shake, pudding, or mixed with other ingredients like Greek yogurt for added texture and flavor. Ensure the casein supplement is of high quality and free from unnecessary additives.

Taking casein protein every night can be a beneficial strategy for enhancing muscle recovery, preventing muscle breakdown, and improving satiety. Supported by scientific evidence, this practice can be particularly useful for athletes and fitness enthusiasts looking to maximize their muscle growth and recovery. As with any supplement, it’s important to consider individual dietary needs and consult with a healthcare provider to tailor the approach to personal health goals.

Final Words

Casein protein, by itself, is excellent if you want to improve the quality of your life. However, it is important to remember that there are certain aspects that casein lacks in comparison to others. That said, it doesn’t mean there aren’t any brands that aren’t as effective as whey protein.

However, one of the best things I can recommend is that you take a whey casein blend to make sure you are able to gain muscle and sustain your muscle synthesis. Moreover, protein balance is incredibly important. Make sure you are not overloading yourself with protein, which could have an adverse influence on your health.


Overall, there are many choices in the market, And I’m not saying that casein proteins are not a good choice.

Casein is certainly one of the best protein sources out there. That said, it’s important to make sure you are taking your health seriously. Make an informed decision and consult your doctor if you’re truly concerned about anything.
