One key variable is that amino acid composition is often displayed as a figure based on 100% protein content. Whilst this may display great results for the amino acid content of a product, a closer look will reveal an accurate reflection of the amino acids within the product you are consuming. The amino acid composition of 100% protein would suggest that a product is 100% protein, which in reality is never the case. For example, 100% whey protein will contain 30-80% actual protein content, depending on the quality of the protein. This means that the amino acid composition of 100% protein becomes redundant, as there are no protein products that contain 100% protein (the closest is our Pure Whey Isolate™ 97). In order for the amino acid quantities to be reflective of the product, the actual percentage of protein needs to be taken into account.
Alternatively, you may see the amino acid composition of the product, but displayed the amino acid content in relation to a dry matter protein figure. This is not reflective of the product that you receive and provides amino acid figures that exceed what you’re actually consuming.
Things to look out for when reviewing amino acid profiles
Something to look out for on amino acid profiles is that the amino acids are reflective of the “as is” protein content of a product. That way you’re getting a true amino acid figure compared to the finished product you’ll receive, not a manipulated figure to make the product seem better than what it really is.
We’ve given examples below of the varying presentation of amino acid data.
