Protein Percentages and what that means to to the effectiveness of the protein.

 The ability to workout the percentage of overall protein content and the percentage of individual proteins in a protein blend, is essential to see if you are really getting what you pay for, and whether the protein will do the job you want it to and what the company is claiming for its use.

 Our article PROTEIN POWDER - PURITY, VALUE, EFFECTIVENESS AND USE explains how to workout what you are getting for your money, I will try to explain more the importance to your nutrition of this information.

If a company claims to have a multi-release protein of fast, medium, and slow release proteins, it needs to have these proteins in around a third of each( a bit higher in fast release is even better for post workout) As mentioned in the above article this means that the protein % has to be in the 80's as the fast acting Isolate is around 88-90% medium release concentrate about 75-77% and slow release casein about 88%. If your protein has a % of around 78% or less there will be no more than 5 % isolate in the product meaning that it is not really suitable for post training, and also will not give the constant release of protein this type of product is supposed to.

Likewise if you purchase a protein that claims to be isolates but shows protein % around 78% instead of 88% then you are not getting isolate and is not suitable for the purpose of getting fast acting protein into your system for post training.

Pure proteins which show less than 70% by volume protein on label are more than likely to contain powdered milk fillers which have a very low uptake rate as well as just 40% protein content.

These formulas do not apply to weight gainers, which contain added carbohydrates for weight gain and energy, but stay away from products that have more than twice the carbs to protein ratio, if you really want to gain muscle as it is the protein content that your body uses for this purpose.

Learn to read your protein labels, and if there is no per 100g column to let you see the percentage, simply divide 100 by the serving size and multiply by the protein per serve, and that will be the protein percentage of the product by label claim.
