Best protein powder for runners in 2023

In our guide to the best protein powders for runners, expert nutritionist Angela MacRitchie answers some of the most common questions when it comes to muscle growth and recovery

Angela MacRitchie is a nutritionist for Battle Ready Fuel, the sports performance nutrition range from Ollie Ollerton, who’s worked in the Special Forces and on SAS Who Dares Wins. Here, she reveals how and when to use the best protein powders for runners to maximise your fitness levels. 


Does protein powder help runners?

Of course, is the reply, so what’s all the hype with protein powders? When you run, your muscles will inflame and break down. It’s therefore important to rebuild those muscles proficiently, which is why protein is needed: to prevent muscle catabolism.

If the muscles are constantly breaking down with every run and not being refuelled with protein, there’ll be muscle wastage and a risk of poorer performance.

But there are many more reasons why we need protein – here are a few:

  • It supports immune function by helping to make antibodies, so the body can fight off infections. This means more time training to reach your goals.
  • It aids the production of red blood cells that carry oxygen in haemoglobin. The more oxygen that reaches your muscles, the more glucose will be converted into ATP (the energy currency).
  • A small study showed that runners improved their time by 16 seconds by taking high protein of 1.83g/kg of body weight.

How much protein do runners need?

There’s no straight answer here as the recommended dietary allowance for protein is 0.8g per kg of body weight. But this will vary depending on the length and intensity of your training. The more energy you burn off, the more protein you will need for fuel.

 Here are a few guidelines on taking protein for runners:

  • If you’re a runner and want to maintain your current weight – aim for 1.4-2.0 g per kg. Go for the higher end of the range if you want to maintain weight and improve body composition: More muscle, less fat.
  • If you’re a runner with a healthy weight and want to build more muscle – aim for 1.6-2.4 g/kg. This may minimise fat gain while you try to develop stronger legs for hill runs.
  • If you are a healthy weight and want to lose fat – aim for 1.6-2.4 g/kg, skewing toward the higher end of this range and increase your calorie deficit, (exercise more or eat less) so you can become leaner.
  • Studies vary from stating that 1.8g per kg has no benefit to showing that 2.2g per kg is the best. However, it’s hard to give a fixed recommendation as it depends on the length and frequency of your runs. 
  • My advice is to aim for amounts between 1.4 – 2.2g per kg. This would cover you for whatever your training regime is.

Should a runner’s chosen protein powder include carbs?

A 3:1 or 4:1 ratio of protein to carbohydrate has been shown in studies to enhance recovery but will load up on the calories. So if you don’t want to do this, add carbohydrates separately and keep the calories down by using oats, berries or a banana in your protein shake. 

As a general rule: 

  • For runs under an hour: add 5-7g/kg of carbohydrates
  • For heavy training: add 7-10g/kg 
  • For long 4-5 hour runs: add 10-12g/kg 

When should runners take protein?

The saying used to go that you should take the protein in the 30-minute window straight after exercise, as the muscles are like a sponge for protein. But now they’ve found that this optimum window may be longer than 30 minutes and not only straight after exercise.

So, it may not matter whether you have protein before or after your workout for optimising repair or growth. 

The main point is: if you’ve trained on an empty stomach or after a meal. If you prefer to train on an empty stomach, I’d recommend you have the protein soon after exercising as the body will be in deficit. But if you have a meal before your running session, take protein when it feels comfortable – even a few hours after the run.
