Q What is whey protein?
A Whey is the ultimate protein in terms of bioavailability and content of essential amino acids, which the body needs on a daily basis to promote a healthy body and assist in maintaining muscle tone. Whey protein is a by-product of cheese making, which has been concentrated and purified by a filtration process to yield a high purity protein product, that is both natural and pure without any added preservatives.

Q How does whey protein compare to other protein sources?
A All The WheyTM Protein Powder is defined as a complete protein because it contains all the essential amino acids which the body requires.
A number of different methods are used to evaluate protein quality but regardless of which method is used, whey protein comes out on top each time.

1 Protein Digestibility Corrected Amino Acid Score measures protein quality based on amino acid requirements of the human body
2 Biological Value measures the amount of protein that is retained from the absorbed protein
3 Protein Efficiency Ratio measures the ability of a protein to support growth
4 Protein Digestibility measures the fraction of the dietary protein that is absorbed from the diet
5 Net Protein Utilization expresses the ratio of nitrogen used for tissue formation to the amount of nitrogen ingested.

Q How does whey protein compare to soy protein?
A Here are some of the differences between whey protein and soy protein.
Whey protein is a nutritionally complete protein. It contains bioactive ingredients, like immunoglobulins and lactoferrin, that help support the immune system.
Athletes prefer whey protein to soy protein due to its rich abundance of branched chain amino acids and its quick absorption rate. These are important to help repair and rebuild muscles after a workout or competitive event.
Whey protein has a fresh, neutral taste compared and will not change the taste of foods you add it to.
Whey protein does not contain isoflavones or any other components with potential hormonal effects.
