  2. Source of whey Isolate

  3. Whey proteins are obtained from milk, milk protein contains whey and casein protein, out of which around 80% is casein and 20% is whey.
    The manufacturing of whey Isolate begins with the liquid whey that is obtained during the cheese-making process (the yellow liquid that we see formed on curd). The liquid whey contains carbohydrates, fats, and other micro-ingredients besides proteins. Liquid whey is then filtered using different membrane filters to remove the carbs, fats, and micro-ingredients. After passing liquid whey through different filters whey protein isolate containing about 90% proteins is produced.

  4. What is the difference between whey concentrate and whey Isolate?

    The primary difference between whey concentrate and whey isolate is the amount of proteins it contains. The usual raw whey concentrate that is used in major sports nutrition supplements contains about 80% proteins, this whey concentrate is filtered further to remove additional lactose and fats to make whey isolate. Raw whey Isolate has a purity of about 90%, meaning it contains 90% of protein by weight.
    Whey concentrate contains about 7% carbs and a few percent of fats while whey isolate contains an even lesser amount of carbs and fats. The percentage can vary a little bit depending on the manufacturer, the filters used during manufacturing, the season of the year, the source material i.e milk, etc.
