This may seem a little obvious but bear with us here, there may be some stuff that you haven’t thought about. I mean, obviously, whey protein powder gives you protein, with a complete amino acid profile and turns you into a big shredded genetic freak, right? Or, is it that whey protein is a poorly absorbed and processed product that has been mis-sold to us by the evil dairy industry? Conversely, it is often cited that plant-based proteins have better bio-availability and better absorption than whey, but is this true?

Protein Absorption

There is considerable research on different types of protein powders, the common ones are whey protein, casein and soy. It is well known that casein is a very slow digesting source of protein and that whey is rapidly absorbed, in fact (1) it is the fastest acting protein supplement on the market. Despite some people claiming that you don’t absorb dairy based proteins the evidence is pretty conclusive. Whey protein is the fastest acting and most compete protein supplement on the market.

When different protein sources are compared, eggs contain the highest quality protein, which makes sense seeing as an egg contains all the amino acids to grow a lifeform. But, interestingly, whey protein has a higher biological value than eggs. Compare this with plant protein sources like black bean, soy or wheat and you can see their biological values are far lower (6).

Even when all factors are adjusted to find their protein digestibility corrected-amino acid score (basically plant proteins tend not to have an optimal amino acid ratio) and all animal proteins are of a higher quality in terms of its anabolic effect and influence on muscle and bone density.

The one exception, as you can see from the list is soy, which has equivocal scores to animal proteins across the board (1). Other types of plant-based protein powders exist as well and one study (7) showed that pea protein had a significant effect on muscle growth compared with a placebo.

The fact is, if you have a plant-based protein supplement you will still trigger muscle protein synthesis and you WILL get gains, but you might have to consume more of it per serving to get the same response as you would from whey. But we’re really only talking about marginal differences here, and this is why we worked hard to ensure that our plant-based protein powders have the best ingredients and the most optimal amino acids profile possible.

Obviously, because whey is derived from cows’ dairy it contains the same proteins and lactose as cows’ milk and other dairy products so if you know that you have an intolerance to cows’ dairy then choose an alternative. It could be that this is the reason some people experience bloating from taking a whey shake, but more on that in a bit.

If you are a high performing athlete or have very specific body composition goals consuming in the region of 1.6 – 2.2g of quality protein per kg of body mass is important. But of course.

Are Protein Shakes Bad For You? 

Another often cited problem regarding consumption of whey protein is that protein is acidic and damages your kidneys. This comes from research done on rats in the last century and has since been debunked (2). In this study trained males were observed consuming up to 3 times the recommended levels of protein and their health markers were not affected. They did, however, see an increase in fat free mass which is a pretty good side effect. More evidence that protein has a positive effect on body composition and, if you aren’t getting enough from your meals then supplementing with a whey protein shake will almost certainly help you to build more muscle.

Some of the highly-researched benefits of whey protein include prevention of allergies, appetite suppression, and for reaching recommended protein levels as well as to alleviate deficiencies experienced in ageing and diabetes (3). Furthermore, it has been observed that conditions like sarcopenia which is a depletion of skeletal muscle and even osteopenia often seen in the elderly may be halted by consumption of a whey protein shake. Douglas Paddon-Jones and Blake B. Rasmussen found that although muscle protein synthesis is dampened in the elderly, consuming 25-30g of high quality protein per meal was beneficial (4).

There is one thing that is worth taking notice of however, and that is amino acid spiking (5). This is a tactic used by some manufacturers to save cost. Basically, they bulk out the total protein with a bunch of non-essential amino acids that play no role in stimulating muscle protein synthesis. This isn’t harmful, it’s just immoral so we recommend you learn how to identify this.

Looking at the above evidence we can see that not only is whey protein safe, it is highly beneficial for more than just building ripped muscles. If your gran or grandad struggle to eat a decent portion of protein dense food at each meal or can’t afford a monthly meat order from Muscle Food, then encouraging them to consume a whey protein shake once or twice per day (or to mix it into their porridge) might be a very simple and effective answer.

Some people do experience bloating and other gastrointestinal symptoms from consuming whey protein. But, this is likely due to an intolerance to dairy. It's worth noting that there’s usually a cut-off point for lactose intolerance which, once breeched, brings on the symptoms, and it might just be that adding a whey shake per day simply pushed that limit for those people. Many of our customers have cited this as their reason for shifting to our vegan blends, which we take great pride in, having also worked very hard on creating a great tasting vegan protein powder, we think ours is the best tasting on the market and we have tried them all.

Saying this, if you are fine with dairy, have good digestion and a healthy diet then whey protein won’t cause you any issues at all and can in fact help you to achieve your body composition goals. 

Real World Benefits Of Protein

That’s a brief look at some of the research and it’s patently clear that whey protein is safe and effective but is it necessary?

Of-course it isn’t necessary but it is very convenient and, as we already stated, consuming more protein can help reduce fat free mass and improve your body composition. Aside from the above let’s look at some other practical uses for whey protein that you might not have thought about - 

  1. Protein is great for baking. Use it as an ingredient in cakes, cookies and flapjacks or make your own protein bars.
  2. Add protein to smoothies for a quick and convenient breakfast or fast recovery drink post workout. 
  3. Add protein to porridge to not only warm you up in the morning but to keep you feeling full right up until lunch.
  4. Protein pancakes, what more do I need to say?
  5. Use protein to stimulate muscle protein synthesis post workout. This isn’t essential because the post exercise anabolic window is longer than most think but a whey shake will stimulate MPS and if your next meal isn’t for a couple of hours a whey shake is ideal.
  6. If you are a large athlete with a high protein demand adding a couple of protein shakes per day will provide a cost effective and easy way to hit your targets.
  7. If you are a cyclist or triathlete you can add protein to your intra ride carb solutions on those longer rides or use whey protein to make up your 3:1 or 4:1 (carb:pro) post-race recovery drink.

That’s a bunch of really good reasons to always have some protein in your cupboard, and fortunately, you don’t have to dive for the shaker cup the instant you put the bar down or be that gym bro walking around sipping whey between sets.

Consumption of whey protein isn’t essential to losing body fat or building muscle but it can be helpful. To burn fat you have to be in an energy deficit, you do that by controlling what goes in your mouth (NOT THAT) and conversely, you build muscle by being in a slight energy surplus and training hard. Protein powder isn’t magic but it is useful, cost effective and can really help to make things a lot easier, as well as helping with adding variety in to your diet.
