How Much Is A Scoop Of Protein Powder?

Figuring out how much protein is in each scoop of protein powder supplements is a vital part of planning your post-workout routine.

Protein powder is generally around 25-30 grams or one ounce, but there are a lot of different products with different target audiences. For example, a professional bodybuilder will be looking for much larger doses than someone doing cardio a couple of times a week.

This guide takes you through everything you need to know about how much protein is in a scoop, why scoop sizes vary, and why this is important for YOU as the consumer.

Key Takeaways:

  • A typical scoop of protein powder is generally about 25-30 grams per serving, depending on the target customer.
  • This can vary a lot depending on the protein powder type and brand, with some products trying to target high-performance athletes.
  • Try using a kitchen scale to get an accurate measurement if you need an exact amount after different training sessions.

How Much is a Scoop of Protein Powder?

The answer is not especially clear if you want to know how much protein powder is in a scoop. It doesn’t matter if you’re taking protein powder supplements or standard powder; the answer is the same.

The thing is, the size of a scoop can VARY between manufacturers, which means you’re getting different weights and quantities of protein in each scoop.

Just one scoop of a milk-based protein powder containing a COMBINATION of casein and whey proteins comes in at 25 grams and provides 12.5 grams of protein.

On the other hand, WHEY protein powder is isolate-based and will typically weigh 28 grams and offer 24 grams of protein.

A protein powder or protein supplements that are plant-based will USUALLY weigh 30 grams and offer 15 grams of protein.

Pro Tip: Protein powder scoop size can also be affected by how DENSELY the powder is packed. So, a protein powder that is less dense will have a larger scoop and vice versa.

Why Do Scoop Sizes Vary?

The protein powder market is HUGELY competitive. So, in order to stand out, some manufacturers make their protein powder SCOOPS larger than others. This is why protein powder scoop sizes can vary so much.

This is also why it is important for you to ALWAYS use the scoop that is provided with your protein powder. If you use your own scoop, you’re going to mess up the portion size.

As a result, you won’t know exactly HOW MUCH protein you’re getting. Your scoop might be bigger or smaller than the one provided by the manufacturer.

What’s the Best Way to Measure Protein Powder?

If you want to make sure you’re taking the same amount of protein powder every time, the best way to do it is by using a KITCHEN SCALE. This way, you know EXACTLY how much protein powder you’re taking and can be sure that you’re getting the same amount each time.

The AMOUNT of protein you need depends on a variety of factors, including:

Research has also been carried out to observe how much protein we should be consuming.

The recommended daily protein intake for SEDENTARY adults is 0.36 grams per pound (0.8 grams per kilogram) of body weight.

For example, a sedentary woman who weighs 140 pounds (64 kg) would need about 50 grams of protein per day.

My name is Michael Smith and I met both Sandra and Dave as clients. I’ve been working as a physiotherapist for the past 10 years now, which is a job I love doing.

See, I once had a promising football career which started with the Texas Longhorns, but unfortunately was cut short after just 1 semester when I suffered quite a serious knee injury.

I spent about 18 months going through 3 surgeries and endless hours of physiotherapy. Unfortunately, it was the end of my pro football career, but it opened my eyes to remaining involved in sports and helping athletes recover.

My main focus is sports injuries and I’m set up as a private practice. Maybe one day I’ll try and become involved in a college or pro football team, but at the moment I enjoy the freedom and flexibility of being my own boss.

In my spare time I still coach football, but unfortunately, I cannot play anymore. The nature of my injury was quite severe and has significantly weakened my knee, so I just can’t take such risks anymore.

But coaching kids and teenagers, and helping them prepare for college try-outs is something I absolutely love doing. And reaching a wider audience with some tips on preventing sports injuries is what I hope to achieve on this site.

We will be happy to hear your thoughts
