What Is Casein Protein?

What Is Casein Protein?

Casein is a protein found in milk that provides all the essential amino acids your body needs, along with high levels of the three BCAAs. Many sports professionals and bodybuilders take casein as a supplement because it's excellent at helping muscle growth.


It's different from other options, especially the alternative milk-based protein whey as it releases amino acids much slower, over several hours. If you take casein before bed, it'll keep your protein levels high whilst you sleep, helping you recover quicker and stopping your muscles from breaking down.

How to Choose a Casein Protein in the UK - Buying Guide

Casein protein powders have many benefits, but how do you know which one is right for you? We've put together this handy guide containing all the key information on protein types and nutritional content to help you decide!

1

Select the Type of Protein That’ll Help You Achieve the Best Results

There are a few different types of casein proteins and blends, each with unique effects. This section will detail what each one is and how it is best used so that you can pick the right one for your needs.

Micellar and Hydrolysate Casein Can Be Used Together

Micellar and Hydrolysate Casein Can Be Used Together

Micellar and hydrolysate are the two main types of casein protein supplements found in powders. You might think you need to decide between one or the other, but you can actually incorporate both into your diet as they work well together. 


Casein hydrolysate is for taking straight after your workout. As it's pre-digested, it allows your body to absorb amino acids quickly, which stops your muscles from breaking down. On the other hand, micellar casein should be taken before bed as it releases amino acids slowly over serval hours. 


The slow-release stops your protein levels from dropping when you're not eating or drinking for long periods, such as while sleeping. This prevents muscles from breaking down, improving strength and increasing mass.

Whey and Casein Mixes Are Thought to Achieve Better Results

Whey and Casein Mixes Are Thought to Achieve Better Results

You'll often see some casein blends containing whey - another fast-release protein that works well with micellar. By taking a mix of the two, you'll significantly increase your muscle mass as whey starts protein synthesis straight after a workout and casein works to prevent muscles from breaking down in the long run.


Although, there is debate over whether this works or not. Some people believe the effects of the whey are lost in a mix because it slows down how fast it's absorbed. If you're unsure, it's best to try different options to see which gives you the best results!


If you're worried about gaining fat from protein powders, look for ones with whey isolate instead of concentrated whey, as it contains less fat and carbohydrates. Also, consider using a powder with whey hydrolysate if you're bodybuilding, as it'll improve performance and recovery.

Checking the Nutritional Content Will Help You Achieve Your Desired Result

Checking the Nutritional Content Will Help You Achieve Your Desired Result

Are you a bodybuilder looking to bulk up fast? To achieve the best physique, look for a casein and whey mix with a large serving suggestion packed full of carbohydrates and calories. It'll cause extreme weight gain and bulk, helping you develop the muscles you dream of.


On the other hand, if you're an athlete looking to improve performance and strength whilst maintaining your figure, pick a mixture with low calories and carbohydrates but high protein. These formulas are less likely to lead to unwanted weight gain, and the protein content will help increase your metabolism so that you can burn calories faster.


If you're a regular gym-goer looking to build muscle, pick a supplement with a 30-gram serving suggestion that contains around 100 calories and 23 - 25 grams of protein. This is the standard formula designed to achieve good results.

3

Look Out for Formulas With Added Beneficial Ingredients

Casein or whey protein isn't the only ingredient you can benefit from in powders. Consider trying a formula with added extras that can further enhance and improve your workout.

Added Vitamins and Nutrients Will Improve the Effects

Added Vitamins and Nutrients Will Improve the Effects

Some powders include extra ingredients to enhance the effects of protein powder. Formulas that include vitamin C further enhance the bodybuilding effects of casein, as it helps repair tissue. B vitamins can also help with muscle growth and repair.


But it's not just vitamins that are added, some powders contain minerals like zinc and magnesium. Adding zinc and magnesium to your diet will improve your aerobic abilities, which in turn, increases performance and builds muscle.

Extra Amino Acids Can Improve Mental Health and Sleep

Extra Amino Acids Can Improve Mental Health and Sleep

If you'd like to lose fat but build lean muscle, consider buying a powder with added 5-HTP, as it's thought to suppress appetite. This ingredient also contains serotonin which can improve your mental health and quality of sleep, allowing the micellar protein to work while you're dreaming.


You might even find some formulas include theanine, which can help you relax before a workout. This is especially beneficial if you drink coffee or take caffeine supplements, as it'll help offset the effects.


Lysine, HMB and leucine are also commonly added to supplements. They're ideal for bodybuilding, as they aid muscle growth, build lean mass and improve strength. Some powders even include a digestive enzyme blend, which will allow you to absorb the protein to help you achieve optimal results.

Whey-Casein Blend With Reduced Fat

Here we have a formula that contains both whey and casein, providing you with the effects of both fast and slow-realise protein. It's not too fattening either, as the whey has been isolated to reduce calories and lactose. It's even suitable for athletics and military personal who are drug tested, and it's been credited by the informed sports programme.


The powder doesn't need to be consumed at a specific time, so this is an ideal option for those who lead busy lives or train at unusual hours. Furthermore, the micellar protein in the mix is high-quality and ultra-filtered.

Most casein proteins come in chocolate, vanilla or strawberry, but with this one, you also have the choice of delicious banana! The formula is also gluten-free, so it's suitable for anyone with an allergy or coeliac disease. If that didn't sell you, it even has an added digestive enzyme blend, which helps your body absorb the casein.


It contains a high level of protein, and the formula has been quality tested, so it's almost certain you'll get good results. The powder has even been assessed to ensure it contains no banned substances that could stop athletes from competing.

The Perfect Powder for After Workouts

Next up, we have some casein hydrolysate that can work alongside the Bulk night-time shake. Use this blend during or after a workout for a fast release and the slow-acting micellar shake before bed. 


The formula comes in mixed berry, topical and unflavoured varieties, making this a great alternative for those who don't like the more common chocolate or vanilla flavours. It has a smaller serving recommendation than some other protein powders, so you might want to take two helpings to get optimal results.

Use this product in the evening before bed as it contains slow-realise micellar casein, which aids muscle recovery. Plus, it's free from soy, so it's suitable for people who have an allergy.


This mix may not be everyone's cup of tea, as some people find the flavour unpleasant. However, it does contain a high protein content, so it's highly likely to produce the effects you're after. 

Summary

Now that you've reached the end of our article, you should know exactly how to choose the right casein powder for your needs. Remember to pay attention to protein content and extra ingredients to find the most effective product for you!
