How to calculate protein percentage

The amount of protein per serving of a particular product is easily identified in the Supplement Facts area. You will see it listed with other ingredients as Protein – 27 g for example. What is the percentage of pure protein in each serving however? When protein is the primary ingredient of interest to you, it’s best to know how to calculate the percentage of protein per serving. As a general guideline that doesn’t involve digging up those old mathematical skills, use the following guideline:

• Canada Protein Isolate
  The protein percentage is typically 90% or more making this one of the most desirable proteins for bodybuilding, weight lifting and other muscle intensive sports.
• Canada Protein Concentrate
  Protein content for whey concentrate is around 70 – 85%. This is due to there being more carbohydrates and fat as opposed to whey isolate. It’s still a very high protein percentage and is regarded by many as the superior protein powder due to lower levels of processing…it’s in more of a natural state.
• Canada Protein Blends and Gainers
  It is difficult to state a range for this type of Whey Protein supplement. They contain many added ingredients that can reduce the percentage of protein per serving. If you must know, the calculator below will allow you to compare similar products in this category

To calculate the percentage of protein per serving, divide the number of grams of protein in a serving by the serving size and then multiply by 100. For example:

ProteinCo Canada Whey Protein Isolate

(27 g protein per serving / Serving size 30 g) x 100 = 90% protein

How to calculate protein percentage from Supplement Facts at ProteinCo Canada

ProteinCo Canada Whey Protein Blend

(22 g protein per serving / Serving size 32 g) x 100 = almost 70% protein

Use this same formula for any protein containing supplement to calculate the protein percentage in each serving. This way you know how much protein you are getting for every serving size you mix and consume. It is also a double check to keep suppliers honest as Whey Protein Isolate for example, should always be 90% or greater. If not, you are paying for filler or other ingredients that you aren’t necessarily interested in.
