The 10 Best Protein Powders of 2023: Whey, Casein, Vegan & More
</p><h2 class=»body-h2″>What is Protein Powder and What Does It Do?</h2><p>Protein powder is essentially powdered and concentrated food. Typically derived from either dairy or plant protein, the main benefit of powdered protein is that its seen as a more convenient means of increasing the amount of the essential <a href=»https://www.menshealth.com/uk/nutrition/a757223/a-beginners-guide-to-protein/» target=»_blank»>muscle-building macronutrient</a> present in your diet.</p><p>The three <a href=»https://www.menshealth.com/uk/nutrition/a746325/the-worlds-best-protein-sources-313853/» target=»_blank»>types of protein powder</a> youll most commonly find are whey protein, the liquid by-product of milk that is separated from curd during cheese production, soy protein, a concentrated form of plant-based protein originating from soybeans, and casein protein, a slow-digesting dairy protein that like whey protein is also derived from milk. Other types of powdered protein supplements include beef, rice, hemp, egg and pea.</p><p>So, what does protein actually do to your body? As <a href=»https://www.mrsport.org/» target=»_blank» rel=»nofollow»>Yiannis Fleming</a>, a sports performance coach and qualified nutritionist, puts it: The protein we consume helps augment recovery and new muscle tissue from our resistance training. As we train and put the muscles under stress, micro-tears occur and it’s the protein that helps to repair and develop new tissue.</p><p>Science backs this. According to a <a href=»https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5852756/» target=»_blank» rel=»nofollow»>study published in the journal Nutrients</a>, ‘protein intake was shown to promote additional gains in lean body mass beyond those observed with resistance exercise alone’.</p><h2 class=»body-h2″>What to Consider When Buying Protein Powder</h2><p>As the name suggests, protein supplements should <em>supplement</em> your diet. They’re a tool for quickly and conveniently topping up your daily protein intake and should support a full and balanced diet as opposed to replacing it. If you can hit your daily protein targets in your day-to-day diet, then great. However, if you find that you’re extreme eating or just struggling to hit your goals, then a protein powder could be worthwhile.</p><p><strong>Related: <a href=»https://www.menshealth.com/uk/nutrition/a755033/the-8-most-common-protein-shake-mistakes/» target=»_blank»>11 of the Most Common Protein Shake Mistakes</a></strong></p><p>As Fleming puts it: Many people are able to consume enough protein from their overall diet that a specific powder may not be required. If you’re familiar with tracking on apps like <a href=»https://www.myfitnesspal.com/» target=»_blank» rel=»nofollow»>MyFitnessPal</a> and can see that you’re consuming within the range of 1.5-2g of protein per kg of bodyweight each day so for example, if you weigh 80kg then this would be 120-160g then it may not be essential to add a protein supplement to your routine.</p><h4 class=»body-h4″>Dietary Requirements</h4><p>Its also worth considering your dietary requirements. Are you lactose intolerant or experiencing discomfort from taking protein powders like whey or casein? asks Fleming. If so, opting for a dairy-free or plant-based alternative is best. Options like pea, soy and hemp are great for those with lactose intolerance and will reduce the likelihood of cramps, pains or IBS symptoms.</p><h4 class=»body-h4″>Calories</h4><p>Consider also whether or not you need a protein powder to provide your diet with more calories, or if you solely need it for protein content. Some powders are higher in calories and more suitable for hard gainers or individuals with a higher energy expenditure, says Fleming. For example, if you’re a lean individual who burns a lot of calories but insists on building muscle, then a higher-calorie powder is likely the one for you.</p><p>Likewise, if you’re just trying to top up your protein or are going for body recomposition (reduce fat & increase muscle simultaneously), then just a standard protein powder will be fine as you will want to eat the majority of your calories from your diet, since this will assist in keeping you satiated.</p><h2 class=»body-h2″>What are The Best Types of Protein Powder?</h2><p>According to Fleming, protein powder should be broken down into the following four categories:</p><h4 class=»body-h4″><strong>High-calorie Dairy Protein Powder</strong></h4><p class=»body-text»><strong></strong>Also known as mass gainers or muscle gainers, these powders are comprised of protein with added carbs and fats to increase your calories’, says Fleming. ‘If you struggle to consume enough calories each day then a powder like this will assist in increasing your bodyweight and muscle stores.'</p><h4 class=»body-h4″><strong>Low-calorie Dairy Protein Powder</strong></h4><p class=»body-text»><strong></strong>Examples of these powders are whey, casein and those labelled as diet» options,’ he continues. ‘They are mostly comprised of protein with very little added carbs or fats, meaning you can consume around 30g of protein for under 150 calories, which is very low when compared to higher-calorie shakes which can be around 600 calories. Keep in mind that whey is best taken after training as it elicits muscle protein synthesis and will support muscle repairs. Casein, on the other hand, is a slower-absorbing powder and best taken pre-bed to help reduce total body protein breakdown, which occurs when we go long periods without eating, e.g. sleeping.'</p><h4 class=»body-h4″><strong>High-calorie Dairy-free Protein Powder</strong></h4><p class=»body-text»><strong></strong>These are similar to the muscle gainers mentioned before. ‘These powders contain additional calories from carbs and fats to help you consume more energy,’ says Fleming. ‘The only main difference is that these shakes do not contain dairy and thus will have a slightly lower leucine content. For eliciting muscle protein synthesis, a dairy-based powder will likely be the best, but if you can’t have dairy, then a shake from this section will be more than fine.'</p><h4 class=»body-h4″><strong>Low-calorie Dairy-free Protein Powder</strong></h4><p>If you’re shopping in this category, look for pea, soy, hemp and those labelled as ‘dairy-free’ options, says Fleming. ‘They are mostly comprised of protein, but as they originate from plants they will have slightly less protein and a little bit more carbohydrates,’ he says. ‘These shakes are not thought to be as effective in eliciting muscle protein synthetic because of their lower leucine content, but they are more advantageous if you are avoiding dairy. You could always combine this shake with a lactose-free milk to further increase the protein content.</p><ol></ol><h2 class=»body-h2″>What to Look for and Avoid in Protein Powder</h2><p>Once youve settled on a type of protein powder, its important to head to a trustworthy retailer. For the majority of people, a cost-effective protein powder from a reliable distributor like <a href=»https://www.myprotein.com/» target=»_blank» rel=»nofollow»>MyProtein</a> or <a href=»https://www.theproteinworks.com/» target=»_blank» rel=»nofollow»>The Protein Works </a>will be more than sufficient, says Fleming. These sites offer a wide range and will cover the four main groups I mentioned before. Remember to opt for a dairy-free or plant-based alternative if you are avoiding dairy.</p><p>If youre an athlete who competes professionally, Fleming says to opt for supplements with a <a href=»https://sport.wetestyoutrust.com/» target=»_blank» rel=»nofollow»>Informed Sport</a> label. These are batch tested to ensure the ingredient list is accurate and to cover you if you’re being tested for performance-enhancing drugs, he says.</p><h2 class=»body-h2″>Men’s Health Lab Approved</h2><p>As part of our <a href=»https://www.menshealth.com/uk/nutrition/a40932512/sports-nutrition-awards/» target=»_blank»>Sports Nutrition Awards</a>, we recruited a panel of over 200 fitness enthusiasts and industry experts and asked them to put a variety of protein powders to the test for four weeks. They provided in-depth feedback on each products nutritional value, impact on exercise performance, ease of use, texture and, importantly, flavour.</p><p>Our winning protein powders have the Sports Nutrition Awards badge displayed proudly above their picture below.

Best Whey Protein Concentrate Powder
Bulk Pure Whey Protein
1
Best Whey Protein Concentrate Powder
Bulk Pure Whey Protein
Pros
Low calorie content per serving
20+ flavour options
Affordable
Cons
Not suitable for hard gainers or bulkers
Consider this whey protein concentrate powder from Bulk as a standard or default pick. With a high protein content (22g per 30g serving) and just 114 calories, 2.2g of fat and less than 1.5g of sugar per serving, it’s a suitable option for anyone looking to top up their protein content while still getting the majority of their calories from their normal diet.
It contains 5g of branched-chain amino acids (BCCA) per serving, which essentially help your body to recover, reduce soreness, support muscle growth and even limit fatigue.
This is a whey protein concentrate powder, which means that it’s less processed than whey isolate or hydrolysed alternatives, but as a result is less filtered and has a lower protein content per weight (typically up to 80%) and therefore more carbohydrates and fat per serving. However, if you exercise a few times a week, it’ll still provide comparable benefits for muscle growth and is generally much cheaper.
Bulk’s Pure Whey Protein was highly rated by our team of testers at the Men’s Health Lab, who described it as a ‘good all-rounder’ and praised the ratio of protein, carbs and fat. The choice of flavours also went down well, with more than 20 ‘tasty yet subtle’ options to choose from including regulars like vanilla and chocolate, as well as more adventurous picks such as rocky road and pistachio ice cream.

Pros
Low in fat, carbs and calories
High protein content by weight
Cons
Not suitable for hard gainers or bulkers
This whey protein isolate powder from Protein Works falls firmly within the ‘low-calorie dairy’ category, registering just 0.1g of fat and 1.1g of carbs per 25g serving. If you’re cutting or watching your calorie intake but still want to pack on lean body mass, this is an excellent option, packing a hefty 23g of protein per 25g scoop, all for a meagre 92 calories.
This is a whey isolate, which means that most of the fat and lactose has been removed during the processing. While this results in a higher protein content per weight 92% in this case and can be easier for people to digest due to the lower lactose content, it’s generally more expensive than whey concentrate. In terms of muscle growth, the benefits are similar.
Protein Works’ Diet Whey Protein Isolate 90 is available in 10 flavours (including unflavoured), is made from ‘ultra premium grass-fed whey protein’ and contains 0.6g of sugar per serving.

Best Hydrolysed Whey Protein Powder
Optimum Nutrition Platinum Hydrowhey
Pros
Lactose-free
Quick absorbing protein
Cons
Expensive
This hydrolysed whey protein powder from Optimum Nutrition delivers 30g of fast absorbing protein per serving as well as 9.5g of naturally occurring and added BCAAs. Again, this is a low-calorie, milk-based protein powder, but due to the way it’s processed contains no lactose great for those with lactose allergies.
This is a hydrolysed whey protein powder the most processed of the three types of whey. It is essentially whey isolate that has undergone an extra pre-digesting process that removes all excess fat or lactose. This is said to make the protein quicker to absorb.
Like whey protein isolate, the additional processing means that hydrolysed whey is fairly expensive. It’s marketed to athletes who train frequently because of its supposed quick absorbing properties. If you’re training a few times a week, you could save yourself the money and opt for a whey isolate or concentrate.
The Platinum Hydrowhey from Optimum Nutrition comes in three flavour options milk chocolate, super strawberry, and vanilla bean.

Best Casein Protein Powder
Bulk Micellar Casein Protein Powder
Pros
Digests slowly
Tops up your protein while you sleep
Cons
Avoid if lactose intolerant
Casein protein powder, such as this from Bulk, is similar to whey protein as it’s also derived from milk. Where it differs is that casein has a much slower rate of digestion. This means that the protein absorbs slower into your body and therefore gradually supplies your cells with protein over an extended period. This makes it a great supplement to take before bed as it helps, as Fleming explains, to reduce total body protein breakdown as we sleep.
Bulk’s Micellar Casein Protein Power contains a healthy 25g of protein per 30g serving and is low in carbohydrates and fat. It’s available to buy in four flavours, including an unflavoured option.

Best High-calorie protein powder
Myprotein Impact Weight Gainer
Pros
Great for a calorie surplus
Super high carbohydrates and calories
Cons
May be difficult to digest
Mass (or weight) gainers such as this from Myprotein have a high carbohydrate and fat content, which means they’re best suited to those on a calorie surplus or anyone that struggles to consume enough calories in a day.
Don’t mistake a weight gainer as being a more effective ‘muscle gainer’ compared to low calorie supplements. The additional carbohydrate, calorie and fat content will, as the name suggests, help you to gain weight, but not necessarily more muscle mass.
This weight gainer contains 30g of protein per 100g, while packing a hefty 50g of carbohydrates and 6.2g of fat. It also comes in five flavours, including an unflavoured option.

Pros
Super high protein content by weight
Contains zero carbs
Cons
Not suitable for vegetarians
Beef protein powder might sound a bit odd, but it’s a great whey alternative for anyone who’s lactose intolerant or following a paelo diet. The main advantage of beef protein powder is that it has a super high protein content by weight (29g per 30g serving in this case) and contains zero carbohydrates and just 0.5g of fat.
It’s worth noting though that because of its high purity, Bulk advises that anyone who buys their unflavoured beef protein powder should mix it with something flavoured due to its ‘unpleasant’ taste. Failing that, choose one of Bulk’s other flavour options: chocolate peanut, chocolate and banana fudge.

How Much Protein Do You Need?
This is one of the most commonly asked questions about protein powder. Fleming stresses the importance of having a consistent daily intake of protein. ‘Before relying solely on a supplement, try to ensure you’re consuming 1.5-2g per kg of bodyweight regularly,’ he says. ‘This is going to help you much more than just consuming one shake a day, for example.’
From there you can decide how much to consume. ‘If you’re slightly under this then a protein powder will be a perfect addition to help,’ he adds.
‘Most powders will come with a scoop providing around 20-30g of protein. For smaller individuals, one scoop with water or milk will be more than sufficient. For larger individuals, 1-2 scoops with water or milk will do fine. Remember that you can lean on milk such as semi-skimmed or soya (plant-based) to help add additional protein to your shake, if it’s necessary.’

When Is the Best Time to Take Protein Powder?
Men’s Health UK
This can depend on the type of protein you’re taking, but most, like whey, soy, pea and hemp ‘will be best taken after training to elicit muscle protein synthesis’, says Fleming. ‘But that doesn’t mean you have to rush to get them in.’
There’s no need for a mad rush, essentially. ‘You can finish training, have a shower, then create your shake, if you prefer. In fact, if you wanted to sip your protein shake during training, this will be equally as beneficial in starting the recovery process as the amino acids will already be in your system.’ Whatever works for you.
Where you should be more particular about timings is with slower absorbing protein powders, such as casein, which are ‘best taken before going a long period without eating as these assist more with reducing the amount of total body protein breakdown’, says Fleming. ‘This may be useful if optimising the amount of muscle you’re carrying around is the priority.’
