Protein is an essential part of any diet, not just for runners. It’s what helps us build muscle, maintain the muscle that we already have, and improves recovery by helping muscle fibers to heal faster after exercise.
It can be easy to let our protein intake drop, especially if we focus more on carbs to fuel us through training runs and races.
One way to ensure we get enough protein in our diet and get an extra running boost is to buy one of the best protein powders for runners.
Our first choice is the GU Roctane Protein Recovery Drink Mix. It contains a premium mix of healthy protein, quick-absorbing carbs, and electrolytes to replenish you in all ways after a hard run.
But we’ve found many other great protein powders that also work. Read on to see them all…
Top 3 Best and Favorites
GU Roctane Protein Recovery Drink Mix
Vega Nutrition Sport Protein
Hammer Nutrition Whey Protein
Best for Recovery
1. GU Roctane Protein Recovery Drink Mix
The GU Roctane Protein Recovery Drink Mix is our top choice, and it does much more than just give you a dose of extra protein in your day.
This is the perfect post-workout recovery drink. The calorie count of 230 per serving may seem a little high for smaller runners who are counting calories, but it’s worth it for what you get out of it.
Those 230 calories will give you 20 grams of easily digestible whey isolate protein, 30 grams of carbs to refuel, and a good injection of electrolytes that you probably expended during your run (230mg of sodium, 200mg potassium, 40mg magnesium, and 100mg calcium).
There are only two flavors available, chocolate and vanilla bean. You can mix both with either water or milk, or even add a sachet of protein powder to a smoothie mix for something different.
It’s best taken shortly after a workout or run. You could take it other times during the day, but you’ll definitely get the best results from it by taking it at the suggested time.
Some people found that mixing it with 8 ounces was too thick, but with 16 ounces it didn’t taste great. You will have to experiment to find the best mix for you.
- 20g of whey protein isolate
- Natural flavor
- Contains L-glutamine and L-arginine
- Helps your body hydrate
- Some may find the protein to be a bit thick when mixed with 8oz of water, but mixing it with 16 oz may leave a bitter aftertaste
Top Plant-Based Protein Powder
2. Vega Nutrition Sport Protein
If you prefer a plant-based protein powder, then this may be the one for you. It uses pea protein and peanut flour to provide the protein content. If you have a peanut allergy, then you should stay well away from this one, unfortunately.
It has been USDA certified organic and includes probiotics and antioxidants to improve your immune system as well. There are 170 calories per serving, and you’ll get 30 grams of high-quality protein. The carbohydrate content is lower, at six grams.
It also contains electrolytes to fill up what you lose during a run. The sodium is a high 270 mg, with 250 mg potassium, 180 mg calcium, and 5.5 mg iron. There’s also almost a full spectrum of amino acids, which help reduce inflammation and repair muscle.
This powder is free from sugar, gluten, and animal products. It isn’t fully vegan because it’s made in a factory that processes non-vegan products, but it’s suitable for vegetarians.
They suggest drinking it 45 to 90 minutes after your workout for the best effect and optimal muscle recovery. Some people may find the protein powder to be thicker than they like and have a bit of a chalky taste.
- Plant-based protein
- Low in carbohydrates
- Includes probiotics and antioxidants
- USDA Organic
- Some people may find that this protein powder is thick and has a chalky taste
Best Low Carb Whey Protein Powder
3. Hammer Nutrition Whey Protein
Although we need carbs for fuel, sometimes you just want a protein powder that doesn’t have many carbs, especially if you prefer to eat your carbs instead of drinking them. The lower carbohydrate count does reduce the calories quite a lot, and one serving of this has just 70 calories.
The protein is a little bit lower than most others, with 17 grams in a serving. There’s only 1 gram of carbs, plus 30mg of sodium and 10mg of calcium for a small electrolyte boost.
This protein drink is great for recovery thanks to the addition of L-glutamine. L-glutamine is an amino acid that is found in muscles. In fact, of the 21 amino acids, it is the most abundant one in muscles. It is depleted quickly when you exercise, which is one of the reasons you get sore muscles after a workout.
Low levels of L-glutamine in the body can lead to some nasty side effects, what runners call “over-training syndrome”. To avoid this, and to help speed up recovery and muscle repair after exercise, this protein powder contains six grams of L-glutamine.
- 70 calories per serving
- Gluten-free and contains no MSG
- Has six grams of L-glutamine
- Hormone and antibiotic-free
- Some people may find the aftertaste off-putting.

It’s unflavored, which means no flavoring is added so you get the taste of the original whey isolate. This also makes it good for adding to food if you don’t like just mixing your protein powder with water or milk. Add it to coffee, soup, or yogurt for a protein-rich meal or drink.
If you mix it with hot liquid like soup or coffee, it may not mix well if you put the whole scoop in at once. Rather sprinkle it and stir it in bit by bit for the best result.
This protein powder also contains almost six grams of BCAAs, so as well as not adding carbs, it will also help you recover faster.
- 25 grams of protein per scoop
- Zero carb protein powder
- Zero fat

Why do runners need protein?
The amount of protein that one needs on a daily basis is 0.8 grams of protein per kilogram of body weight. That’s what the average person needs just to prevent themselves from getting sick!
When you’re exercising, you would need to increase the amount of protein to speed up muscle growth and recovery. Consuming the right amount of protein can prevent injuries and aid in the recovery of an injury, as it helps rebuild the muscle fibers.
You don’t want to train hard for a marathon and have your body converting muscle to a fuel source. You want to build lean muscle, and to do that you need to consume from 1.2 grams up to 1.7 grams of protein per kg of body weight.
The amount of protein you’d require would be based on the type of running you’re doing. For example, if you’re running a 10k marathon or a half marathon then you’d start with 1.2 grams of protein per kg of body weight. To work out your weight in kgs, divide your weight in pounds by 2.2. As an example:
- 180 pounds / 2.2 = 81.8 kgs
Now to find out how much protein you need, you’d work it out as follows:
- 81.8 kg’s x 1.2 (grams of protein) = 98.16 grams of protein per day
Depending on the type of training you’re doing on a daily basis and the type of running you’re doing, you can increase this to 1.5 grams but it’s advisable not to go over 1.7 grams of protein per kilo.
Why is protein powder beneficial?
Protein powders contain higher amounts of protein, which you’re able to have in one go without feeling as though you’ve eaten too much. You don’t have to plan meals in advance and spend hours preparing high-protein meals to eat throughout the day.
You can make your protein smoothie in the morning and take it with you to have as a snack between your meals. If you don’t make a smoothie, all you need to do is add a scoop to some milk or water, shake and drink. It’s quick, convenient and you’ll find that most protein powders will keep you fuller for longer, preventing unwanted trips to the vending machine.
When should runners drink a protein shake?
While there’s no real hard and fast answer to this question, most fitness enthusiasts will tell you to have the protein shake 15 to 60 minutes after exercise. Most will also refer to this time as the “anabolic window”.
Recent research has shown that the time when you consume protein does have an impact on muscle repair and growth. For the best results, you should have high-quality protein within two hours after you’ve exercised.
What is important to know before you buy?
Before buying your protein powder, you want to do your research on the brand and the ingredients. Compare the protein powders to others and look at how many grams of protein they offer per scoop. You also want to see how many essential amino acids they contain (BCAA’s), as these will support and boost your immune system as well as aid in your recovery.
Look for a protein powder that has one of the following:
- Informed Sports Seal of Approval
- NPA A-rated GMP
This confirms that the products are free from banned substances and can be used in sporting events, like Ironman.
Protein powder will become a part of your everyday life, and once you’ve found a brand that you like, you may want to see if it has any bulk options. The price will be important, especially long term, as buying in bulk can significantly decrease the price.
Can protein have side effects?
Using protein powder is safe and can help maintain and build muscle. However, there are side effects as well, some of which may be embarrassing, such as:
- Gas that has a sulfur-like odor
- Stomach cramps
You’d need to check the protein powder ingredients before you buy it, as some are lactose and gluten-free, but they may also contain traces of peanuts. There are whey protein powders that do still contain milk (lactose), so you’d need to look at the fine print and check for allergens on the label.
Monitor your water consumption, as you could dehydrate when using a protein powder if you’re not drinking enough.
