Best protein powder for rapid recovery and building lean muscle
Seven high-quality protein powders tried and tested by our team of experts
Protein is a vital macronutrient that our bodies chiefly use for maintenance, repair and growth. When mixed into a shake, the best protein powders are a convenient way to deliver the nutrient after a workout, or whenever we need to top up our protein levels.
As well as building muscle, protein can also help those looking to lose weight, as has the added benefit of increasing satiety levels, helping us feel fuller for longer, according to evidence from the British Journal of Nutrition. Ensuring you get adequate protein will also help to support your metabolism, immune system and hormonal balance.
While the best sources of protein are healthy whole foods, most of us find it difficult to do that within the 60-minute post-exercise window that gives optimal recovery. This is where protein powders come into their own, as they are convenient, easy to digest post-exercise, and can be consumed on the move.
The best protein powders are made without cheap fillers to bulk them out, are free from artificial ingredients, and contain quality sources of protein. Here at Fit&Well, we've tested a great number of protein powders, but the ones we've selected here are the very best of them.
If you're looking for female-specific options, see our buying guide to the best protein powder for women, and we also have a guide to the best protein powder for weight loss.
Best protein powder overall
This super-refined product is the best protein powder for anyone looking to target lean muscle. A 30g serving contains 25g of protein, 90mg of calcium, and that's pretty much it. As a result, it's low in carbs and calories.
All the protein in Dymatize Nutrition ISO100 comes from whey protein isolate, so it’s great for those who have digestion issues with whey concentrate. The inclusion of hydrolyzed whey protein isolate means the protein gets absorbed rapidly too.
We enjoyed the taste during testing, which came without the overpowering sweetness you can get in some rival brands, even in the Birthday Cake flavor, which we expected to be sweet. It mixes pretty easily with liquids, although when stirred into oatmeal, unlike most protein powders, which work as a thickening agent, we found Dymatize actually had the opposite effect and made the porridge slightly runnier.
There are 10 different flavors to choose from, ranging from standard options like Strawberry and Chocolate to more imaginative ones, such as Orange Ice Cream and Chocolate Coconut. Tub sizes are large at 932g or 2,264g, which is great for bulk buying, but could be a lot of powder to get through if it turns out you aren't keen on that particular flavor.
Best budget protein powder
Myprotein Impact Whey Protein is a top choice for value. It provides a hefty 38g dose of protein per 60g serving, though that is twice the serving size of most of the options here, which means you get a lot more calories too.
The protein comes from whey concentrate (rather than the pricier isolate), which some people find causes bloating and digestive issues. There are minimal ingredients, although some of the options include artificial flavors.
There are a huge 40 different flavors to choose from and a range of sizes, from 250g to 5kg bags, the latter offering the best value. If you’re overwhelmed by the number of flavor options, there are sample packs containing up to eight different options to try before committing to a larger size.
We tested the Chocolate Smooth, which worked well with liquids and mixed into oatmeal. Our sweet-toothed testers also liked the Sticky Toffee Pudding flavor, while those who preferred something a bit simpler opted for Vanilla or Strawberry.
If you're looking to cut calories, there are better options in this guide. But if it’s just a straightforward, no-frills product you want, this could be the best protein powder for you.
Best plant-based protein powder
Form Performance Protein gives a hefty 30g of plant-based protein per 40g serving, plus a complete essential amino acid (EAAs) profile with 5g of branched chain amino acids (BCAAs) to aid muscle growth and maintenance. It also contains 6g of glutamine, a non-essential amino acid that can be deficient after intense exercise.
The protein blend is a mix of organic pea, brown rice, and pumpkin seed proteins. It also contains curcumin and black pepper, both of which have anti-inflammatory properties to aid post-workout recovery.
Some vegan powders can be on the grittier side, however, Form Performance Protein has a smooth texture and is easy to mix. Flavors are limited to just five options, but they are interesting combinations: Banoffee, Chocolate Hazelnut, Chocolate Peanut, Tiramasu, and Vanilla. We tested the latter, and it was on the sweeter end of the spectrum.
Form is a Certified B Corporation, which means the brand is committed to sustainable, ethical, and environmental standards. The packaging is plastic-free and compostable, so as well as being free from animal products, you're also getting a protein powder that has good eco and ethical standards all round. Zero plastic means you'll need to use a spoon or your own scoop though.
Best protein powder for weight loss
While Innermost The Lean Protein is our best protein powder for women, there is no reason men looking to lose weight should not consider it too.
In addition to 29g of protein per 40g serving, this powder comes with extra ingredients designed to promote fat loss. It contains 750mg of Acetyl L-Carnitine, a non-essential amino acid that plays a key role in energy production. Essentially, it helps process fat more efficiently as an energy source.
Additional ingredients include 'superfoods' linked to weight management and improved glucose control. A serving contains 500mg of pomegranate, 250mg of bilberries, and 500mg of yerba mate. You also get 1g of inulin per serving. Inulin is a prebiotic fiber that feeds beneficial gut bacteria.
Our testers really enjoyed the taste of Innermost The Lean Protein. It’s smooth and creamy, and blends easily with liquids. It only comes in three flavors though: vanilla, strawberry, and chocolate.
The best vegan protein powder for weight loss
With a decent 25g of protein per 30g serving, just 1.9g of carbs, 0.6g of fat, and a very low 89kcal calorie count, Vegan Wondershake is a fantastic option if you're looking to lose weight.
The protein blend comes from four different sources: pea, soy, pumpkin, and brown rice. Of the four, all but brown rice are technically complete protein sources containing all nine essential amino acids. I say technically, as pea and pumpkin are low in methionine and lysine. The four-ingredient blend means Vegan Wondershake still ticks all the amino acid boxes though.
It also has added DigeZyme—a proprietary blend of five digestive enzymes designed to help with vitamin and mineral absorption.
Vegan Wondershake is the smoothest-tasting vegan protein powder we have tried. It mixes easily to give a creamy texture when mixed with either water or plant milks. It's also a brand we would recommend if you have swallowing issues (one of our testers used it following throat surgery), as there's minimal cloying effect, which along with the super smooth texture, makes it really easy to get down.
We tested the Chocolate Caramel Biscuit and Banana Smooth flavors and really enjoyed them both. There are eight other options, ranging from Vanilla and Double Chocolate, to Chocolate Peanut Cookies and Strawberries and Cream.
Best low carb protein powder
Transparent Labs 100% Grass-fed packs in 28g of protein per 32g serving. It's also a great choice for anyone looking to manage their carbohydrate intake with only 1g of carbs, 1g of fat, and 120kcal.
The protein comes from 100% whey isolate, which is easier to absorb than whey concentrate. The minimal ingredients list includes natural flavorings, steviol glycosides (natural sweeteners) and sunflower lecithin (a natural emulsifier), so it is vegetarian and gluten-free.
We tested the Cinnamon French Toast flavor, which was delicious without being too sweet. We didn’t feel overly full after drinking it either. Some protein powders clog when mixed, but we didn't have any issues with 100% Grass-fed. It mixes really well to create a smooth-tasting drink.
The whey powder is made using dairy products from 100% grass-fed and hormone-free cows. While we're yet to test it, Transparent Labs also has an Organic Vegan option for those following a plant-based diet.
The whey isolate means it's easy on your stomach, there's minimal lactose, fat, and cholesterol, making this a well-rounded and nutritious, low-carb protein powder for supplementing your diet.
Best meal replacement protein powder
Vivo Life All-In-One Meal is one of the few meal replacement powders made with all-natural ingredients. A 40g serving provides 21g of protein, 5.2g of carbs and 4.4g of fat. That fat content may sound relatively high, but the majority of it comes from the golden flaxseed powder containing Omega 3, 6, and 9 fatty acids that help with heart, brain, eye, and skin health, boost energy levels, and support the immune system.
The protein comes from fermented yellow pea (for easier digestion), cold-pressed hemp, and pumpkin seed. The three ingredients combine to form a complete protein with all nine essential amino acids present.
Vivo Life has prioritized easy digestion by adding turmeric and ginger which reduce digestive issues and guard against inflammation. The powder also includes five beneficial gut bacteria along with Konjac fiber, a soluble dietary fiber and prebiotic that promotes satiety by absorbing water, lowers cholesterol, and helps manage blood sugar.
All-In-One Meal comes in three flavours: Vanilla, Caramel Biscuit, and Strawberry. We tested the first two and really enjoyed the Vanilla, but opinions differed on the Caramel Biscuit as some of our testers found it a little too sweet.
Two pack sizes are available, 291g (seven servings) and 1kg (25 servings). All-In-One Meal comes in a plastic bag without a scoop, and is made in a factory powered by renewable energy in the UK.

Packaging: We assess the tub or bag for its overall environmental impact and ease of use.
Frequently asked questions
What is protein powder and how does it work?
Protein is a vital macronutrient—the fundamental building block of the human body. While we often associate it with bulging biceps, protein is the structural architect of your hair, skin, nails, and even your skeletal system.
When you consume protein, your digestive system breaks it down into individual amino acids. Think of these as a biological LEGO set that your body reassembles to fuel your metabolism and maintain lean tissue.
To understand why protein powders have become so popular, we have to look at what happens during a workout. When you engage in resistance training, you aren't actually building muscle in the gym; you’re creating micro-tears in your muscle fibers.
To repair those microscopic injuries, the body initiates a process of protein synthesis, shuttling amino acids and blood flow to the affected area. This mending process doesn't just return the muscle to its original state—it builds it back thicker and more resilient than before. If your protein intake is insufficient, your body will lack the raw materials to finish this job properly.
For women especially, a protein deficit can lead to more than just slow gains; it can disrupt hormonal balance and cause a sluggish metabolism.
This is where protein powders come in. While whole foods are an essential part of your daily nutrition, protein powders offer easy bioavailability and convenience. A post-workout shake kickstarts the repair process during the critical post-exercise recovery window (20 to 60 minutes).
However, the benefits aren't limited to the gym floor. Integrating a scoop into your morning oatmeal, Greek yogurt, or pancakes can significantly boost your day's nutritional trajectory.
A study published in The American Journal of Clinical Nutrition highlighted a fascinating psychological benefit: appetite control. The research found that high-protein breakfasts improved satiety in adolescent girls by positively influencing the neural pathways that trigger hunger. By signaling to the brain that the body is "full," a protein-rich start to the day can effectively reduce the urge for mindless snacking later on.
Protein powder is a versatile tool for healthy living. By understanding how to leverage it—whether for muscle repair after a heavy lift or for curbing cravings at the breakfast table—you can better support your body's natural drive to stay strong, balanced, and energized.
How do I choose the best protein powder for me?
If you're new to protein powders, with so many options, it can be a little tricky to know where to start. To decide which protein powder is the best option for you, begin by looking at how much exercise you do and what type. If you're a powerlifter your needs will be different from that of a committed runner. Do you train in a gym or do you like to mix it up with your own home workout ideas?
If your main goal is to gain large amounts of muscle, perhaps as a weightlifter, body builder or other power-focused athlete, then you will likely want to maximize your protein intake, but it's important not to overdo it.
"In recent years, there have been high levels of heavy metals found in certain protein powders," says Julie Stefanski, a registered dietitian nutritionist. "It's important to research the company’s testing for these contaminants."
Registered dietitian, Alyssa Fontaine, offers some other aspects to consider. “Try to look for a protein powder that is mainly protein and free of artificial sweeteners,” Fontaine says.
“Some research shows that artificial sweeteners can increase cravings for sugary foods. Also, many protein powders contain gums, which are used as thickeners, but they may be harder to digest and cause diarrhoea due to their laxative effect.”
Are protein powders suitable for vegetarians and vegans?
Most powders contain either whey protein or a plant-based blend. The type you choose will likely come down to your general dietary requirements. All the powders here are vegetarian-friendly, but there are some brands out there that are not, as they contain additives such as bovine collagen, for example.
Vegan-friendly powders tend to use a variety of plant proteins (such as pea, soy, hemp, pumpkin, and brown rice) in order to at least get a balance of all nine essential amino acids (EEAs). This isn't an issue for whey-based powders, which contain all twenty amino acids, and are high in EAAs and branched-chain amino acids (BCAAs).
How much protein do I need each day?
Moderately active people should aim to get 1.2 to 1.5g of protein per kg of body weight daily. While heavier exercisers should look to be getting around 2g per kg of their overall weight. For example, a 50kg woman doing regular exercise should look to get around 100g of protein per day.
Most protein powders offer around 25g to 30g of protein per serving, so you should look to be getting your remaining daily requirements from eating healthy whole foods.
Is there a difference between male and female protein powders?
All protein powders are different, but there aren't any hard and fast rules that separate female-oriented protein powders from their male counterparts. The difference is usually just how they are marketed.
“The differences between male and female protein powders depend on how the company markets their use,” says Christina Dieli-Conwright, Associate Professor of Medicine at Harvard Medical School.
“Manufacturers targeting men typically highlight building muscle mass, while for women may highlight weight loss. Nonetheless, the powder should achieve a similar goal of providing a protein supplement.”
However, there are some female-focused powders that have ingredients designed to specifically support female health, such as folic acid, vitamin B6, and iron. While they can be helpful, it's a better idea to get these nutrients from your diet.
It's also worth noting that women generally need fewer calories and less protein than men, so make sure you’re not over-consuming protein powders if you decide to use them.
Is it ok to drink protein shakes when I've not been working out?
Drinking a protein shake without working out is not a problem, says sports nutritionist Jess Hillard. Although you should be aware of the extra calories you're consuming.
"If we are not working out, exercising, or training and eating a balanced diet, then there is most likely no reason to have protein shakes," she explains. "You could end up turning these extra calories you're consuming into weight gain."
However, some people use the best protein powders for weight loss as protein tends to increase satiety, making you feel fuller for longer, which can help to avoid unwanted snacking and maintain a calorie deficit. So whether you should drink protein shakes on rest days will depend on your goals and overall daily nutritional intake.
