Casein Protein Powder Guide

The two main proteins found in milk and dairy products are whey and casein; if you have ever heard of the phrase “curds and whey” then you will probably be aware that it refers to these two types of protein.

Whey protein is the liquid fraction which is dried into the whey protein powders we are all familiar with. Casein on the other hand is the protein that forms as globules or “curds,” and can be used for slightly different purposes.

Usually overshadowed by it’s more popular brother, whey, casein can sometimes go unnoticed by people who could benefit most from it. There are many reasons someone should take casein and many reason why someone should take whey, and many reasons why someone should take both! (I do).

Benefits of Casein Protein Powders

As with any protein, one of casein’s main jobs is to help your body repair and build muscle. However there is a slight difference in how it gets the job done compared to whey, soy or any other plant or meat based protein.

The main benefit of casein protein is that it digests far slower than whey protein. This makes it an excellent alternative when you want something that will keep you feeling fuller for longer, or you want a protein source that will offer a sustained release of amino acids into your bloodstream while you sleep at night. Not only does this nourish your body, replenish and repair muscles but it keeps your body from shutting down the muscle building process. Keep this in mind when deciding when to actually sip on your casein protein shakes.

When to Take a Casein Protein Shake

As stated above, casein is a slow digesting protein so you want to factor that into your decision as to when to take it. As with a lot of supplements, it doesn’t matter too much when you take it because your body is going to absorb it regardless, however since its casein is so slowly digested, there are a few recommended times to get the most out of it.

  • When you wake up, before breakfast (and especially if you don’t eat breakfast)
  • A few hours before your workouts (It’ll give your energy and nourishment and can help you avoid feeling depleted at the gym)
  • Immediately after your workouts
    • Here’s a tip! Mix whey and casein protein powder after your workout for immediate nourishment from whey and prolonged nourishment from casein. It’s what I do!
  • Right before bed (my favorite time since your body is without food for 8hrs, so it’s a good choice to give it some slow digesting nutrients right before you snooze)

Always speak with a medical professional or doctor before taking any supplements. Always read the product label for instructions and directions.

What Are Some Natural Sources of Casein Protein?

Casein comes from milk, (milk is made up of 80% casein protein and 20% whey protein) so it is found in any products that stem from that. Most dairy products come from milk as well, but i didn’t need to tell you that! Here is a quick list of some foods that are high in casein protein.

  • Milk (80% Casein!)
  • Hard Cheese (any kind)
  • Cottage Cheese
  • Sour Cream
  • Greek yogurt
  • Regular yogurt
  • Pudding

Who Should Consider Buying a Casein Supplement?

This question gets brought up a lot. Do I need an actual casein supplement? Can’t I just get it from natural sources?

The answer is no and yes. Not many people need a casein product but i’ll go over the ones who should definitely consider it and who would benefit from adding it to their daily diet.

Any athlete can benefit from casein, this ranges from bodybuilders to powerlifters to football players. If you’re enganged in intense daily physical activity, then odds are you can surely benefit from casein protein supplementation.

People who don’t eat enough dairy products can vastly benefit from a casein product since they aren’t getting it from natural sources. Some people just don’t like the taste of dairy, that’s fine, that’s why things like casein protein powders exist! You can mix it with water and chug it down and you’ll have your daily dose of casein.

Lastly, anyone who is struggling with a protein deficiency. This one is pretty obvious, if you are having trouble getting enough protein during the day or if you’re doctor recommends a supplement then you can’t go wrong with casein. It’s slow digesting and may fill your protein needs.

Who should avoid casein?

If you aren’t working out hard, training for something, or have any goals in mind then you most likely don’t need it. A supplement like this is for more serious fitness enthusiasts that have their diets in check and would like to tack on the extra nutrients to further their reach in their journey.

Save your money if you only workout once in a while!

Wrapping Things Up

So as can be seen from this year’s casein protein powder rankings, there is quite a lot of variation in terms of the purity and value for money offered by products in this field. But don’t fret, any item on this list is going to deliver you a solid dose of casein. We have gone through hundreds of them to narrow it down to 10, so rest assured all of these are quality products.

Going for the best on this list does not necessarily mean that you are going to be paying more on a dollar-per-pound basis, so pay attention to the amount of protein provided in each serving as well as any additional ingredients that may help things such as digestion and performance in the gym. Also consider how much you’re going to need, how often you’ll take it and whether it’s worth buying a bigger tub or not. Bigger tubs usually give you more bang for your buck, but if you don’t plan on using it that often, it’ll most likely expire before you’ve used it all up.

By doing this you are sure to find the best casein protein powder to meet your needs and your training goals. And always remember, supplements are meant to aid you, not do the work for you. They aren’t a crutch or a magic solution to all your problems.

Casein protein supplements are a wonderful way to meet your dietary protein needs, but if you aren’t getting your needs from food FIRST and FOREMOST, then you’re making a mistake. Always take supplements after you have implemented all other natural options.
