What is whey powder?

Whey protein is the amino acid, rich liquid by-product created from cheese production. Besides the high concentration of amino acids, whey protein contains major protein fractions known as beta–lactoglobulin, alpha-lactalbumin, bovine serum albumin and immunoglobulin's.

What is the difference between whey protein concentrate and whey protein isolate?

Whey protein concentrate contains less protein than an isolate but more carbohydrates, fats and major protein fractions. Typically the whey protein concentrate contains 80% protein and approximately 5% fat and carbohydrates, whereas the whey protein isolate typically contains 90% protein and less than 1% fat and carbohydrates.

Whey Protein Isolate is a fast releasing protein powder useful for tissue repair, poor nutritional status and the elderly and is best taken just before a workout to allow rapid absorption of amino acids that are required for muscle growth and tissue repair. Whereas a Whey Protein Concentrate is a slower releasing protein powder and is best taken throughout the day for maintenance, weight loss and other specific health conditions.

What is rBST?

rBST is an artificial growth hormone called recombinant bovine somatotropin originally developed by Monsanto and marketed as Posilac. The United States of America is the only country to allow rBST to be used in dairy cattle. rBST is banned in Australia, New Zealand, Canada, Japan and the European Union. The American Food and Drug Administration (FDA) do not require any special labelling of products produced from cows that are given rBST. We do not use any whey protein powders that come from the United States of America and source only the highest quality products from Australia and New Zealand.

Why are your whey protein powders unflavoured?

Nearly all flavoured whey protein powders on the market today contain artificial sweeteners. As a naturopath and nutritionist I know and have seen the toxic side effects artificial sweeteners can have on your health. There are many naturally occurring substances that you can use to flavour your whey protein powder with such as; cocoa, carob, cinnamon, fresh or frozen berries, banana or other fruits, raw honey, nutmeg or stevia etc. This is not only better for your health, but allows you to choose from a variety of flavours that you can add yourself.

Is whey protein powder only for bodybuilders?

No, whey protein powder can be used by anyone for a variety of needs. Most people commonly associate whey protein powder with bodybuilding, as it is excellent in speeding up the building and repair of muscle. Whey protein is very high in amino acids, which are the building blocks of life and nearly every single cell in your body requires them. As such, there are many people who may benefit from whey protein such as; those who need to lose weight, have a reduced appetite, are on a low carbohydrate diet, the elderly, those with low muscle mass, people who suffer from diabetics, appetite suppression or have low protein intake. It can also be of benefit with detoxification.

What does the biological value of whey protein mean?

Biological value is a measurement of the amount of protein retained in the human body per gram of protein absorbed. The higher the biological value of a given food or supplement, the greater the retention of its constituent protein. The standard biological value upon which other foods are measured is whole eggs – which have a biological value of 100. Whey protein powder has a biological value greater than 110, and as such is one of only a few foods with a higher biological value than whole eggs.
