If you’re getting into your fitness, or are looking to conveniently boost your protein intake, then you’ve probably heard about protein shakes.
If you’re looking for info that’s a bit more backed up than the “bro science” you get from your gym buddies, then you’ve come to the right place. Let’s find out more about the benefits of protein shakes.
What Are Protein Shakes?
Protein shakes are made from protein powder, which is a dry, powdered supplement that can be derived from both animal or plant-based protein sources. It can be flavoured or unflavoured, and is most often mixed with water, milk, or another liquid as part of a protein shake or smoothie.
Protein powder can also be used in a variety of other ways - like baking or mixing into oatmeal or cereal.
Some common forms of protein powder are whey, casein (both isolated from cow’s milk), soy, and pea protein.
Protein shakes are a way to supplement, which means to add to, your daily dietary intake of protein.
What Are The Benefits Of Protein Shakes?
Our bodies need protein for many daily tasks — boosting our immune system, sending messages throughout the body, growth and repair of cells and tissues.
However, the benefits of protein powder mostly focus on functional abilities, like adding lean mass, improving muscle recovery, and increasing satiety.
1. Protein shakes can aid muscle growth
The main benefit of protein shakes is the fuel they provide to help build up muscle tissue after weight training (anabolism).
Our muscles are slowly breaking down when we push them to the limit with exercise, and “feeding” them protein helps them to rebuild and become stronger.
Research shows that protein supplements, along with a strength training routine, build and conserve muscle tissue as well as increase strength.
2. Protein can help you to lose weight
The muscle-building power of protein powders can also help those who want to lose weight.
While a calorie deficit is the most important part of losing weight (burning more calories than you eat), making your diet higher in protein can help to preserve your muscle mass and target fat loss.
Additionally, protein slows down the digestive process, which gives you a feeling of being full longer after you eat. This can decrease overeating and help with weight loss.
3. Taking protein before bed can speed up recovery.
We all want to avoid those post-workout DOMS and ensuring you’re getting enough protein can help with that. Protein helps to rebuild muscle after a workout by muscle protein synthesis, so that they’re ready to take on your next workout, and having a hit of protein before bed can improve this.
4. Protein Shakes Can Boost Your Metabolism
Because using protein shakes gives your muscles the fuel they need to build and repair, your body will target fat burning during workouts. Consistent workouts and protein in your diet increases your lean mass, which requires more calories for fuel - and long term, increases your metabolism.
5. Protein Shakes Can Preserve Muscle Mass
Just like protein helps rebuild and repair muscle after a workout, it can help prevent the muscle loss that comes with the aging process. Research shows that older adults who consistently use protein supplements can slow down the loss of muscle tissue, protecting their bones and overall health.
6. Protein Shakes are Convenient
Rather than roasting a whole chicken, or soaking your lentils overnight, how about simply adding powder to water and shaking it up? It’s easy to use at home, at work, or on the go.
Protein powder is a pure source of protein that’s also low in fats and carbs (unlike some other food sources) that you can knock back straight after your workout. It’s never been so easy to boost your nutrients.
Types of protein
Whey is a protein source that comes from the liquid that is leftover when using cow’s milk to make cheese. It is dried and processed to the powdered supplement form.
Based on the level of processing and refining, there are three different types of whey protein powder: concentrate, isolate, and hydrolysed whey. All forms of whey are considered a complete source of protein, containing all of the amino acid building blocks that our bodies need.
Whey concentrate is the most common type of whey protein supplement. It has less protein per gram than the isolate or hydrolysed forms due to less processing.
However, this also makes it a lower price point and still contains between 30-90% protein. It can still contain some carbs in the form of lactose (milk sugar), which may be a concern for those with lactose intolerance.
Whey concentrate can take longer to digest than isolate or hydrolysed forms, giving your muscles a chance to absorb the protein over time.
Whey isolate is the next level of processing that refines the protein powder further. It contains upwards of 90% protein, and very little carbs or fat.
Isolate contains little to no lactose making it more easily digestible. You may pay a higher price for the further level of refinement of this type of protein powder.
Hydrolysed whey protein takes the longer chains of peptides (protein) and breaks them into small chains of amino acids; the goal is to make this type of protein be absorbed more quickly and easily.
The amino acids are still effective in muscle repair and growth but are often used to limit the potential for allergic reactions to milk (like in baby formulas).
Hydrolysed whey contains between more than 75% protein content with little protein and fat.
Protein blends are exactly what’s said on the tin — a blend of different types of nutrients and protein. If you’re looking to get a little more than usual from your protein shake, then they’re often topped up with extra nutrients. Here’s some examples of ours to give you an idea.
Total Protein Blend contains all three forms of whey (to maximise both quick and slow absorption over time) as well as protein from casein (another milk protein that absorbs slowly) and egg whites.
Consuming a blend of proteins offers you the best benefits of each while also providing varied amino acids to maximise muscle building. Total Protein Blend packs an impressive 24g of protein per serving.
THE Whey is the ultimate combination of all three types of whey protein to provide great benefit to your muscles. The addition of MyZyme helps your body digest the protein into the smaller amino acid building blocks to maximise their benefits. It packs 25g of protein between the various sources of whey and comes in several flavours.
THE Whey+ is the superman of protein powders. Not only is it packed with the benefits of whey protein, but it also contains ingredients that can improve muscle building and recovery through a phased release approach.
If your goal is to add bulk and muscle, a weight gainer blend might be best for you. It contains not only high-quality protein (and a LOT at 31g per serving), but also carbohydrates and a high calorie count to help you add mass.
A weight gainer blend is convenient, much easier than making extra meals, and you can feel good about the quality of the calories and protein that you’re consuming.
Myprotein’s Vegan Protein Blend combines pea and fava bean proteins to give a complete range of the amino acids your body needs.
It can be difficult to find all of the essential amino acids in plant-based proteins, but this blend contains them all in a 22g protein serving.
For anyone who wants to avoid animal-based proteins, the Vegan Blend can boost your protein intake and help you feel confident that you’re fuelling your body properly.
You can also get vegan protein powders made from soy or pea protein — there's more choice than you think so that you can find the right one for you.
Casein is another protein powder made from milk proteins, but it’s digested much more slowly than whey protein powders.
While it seems obvious that you want quickly digesting protein after your workout, casein is a great option for later in the day — like before bed — when you want to fuel your muscles to repair and rebuild overnight.
Adding casein as part of your protein shake regimen can change the game, since our muscles take up to 24 hours to absorb protein after a workout.
Collagen is one of the most abundant proteins in our body and makes up a good portion of our connective tissues (muscle, cartilage) as well as our hair, skin, and nails. Collagen in supplements is usually sourced from chicken or beef.
Myprotein’s Collagen Protein Powder is hydrolysed, making it easy for the body to absorb and reap the benefits. It’s a great complement to whey protein as it contains higher levels of certain amino acids that are lower in a typical whey supplement.
Take Home Message
While there are many types of protein powders on the market targeting different goals, the benefits of using protein shakes can be useful for anyone. Whether you choose any of the types of whey protein, casein, vegan sourced, or collagen, your muscles (and the rest of your body) will be stronger and ready to perform at their best when you fuel them with high quality protein shakes.
