What is Whey Protein?
Whey protein is a by-product of cheese, casein and yoghurt production. After being separated, the whey liquid begins the process of being refined with the final product being a fast-digesting whey protein powder.
Whey protein offers a convenient way to increase your daily protein intake by 25 to 50g by simply consuming one or two shakes.
Whey Protein Isolate vs Concentrate
The difference is Whey Protein Isolate has been filtered to a point where it offers a higher source of protein while containing minimal fats and carbohydrates per serve.
Whereas Bulk Nutrients’ Whey Protein Concentrate, while still being ultra-filtered contains a slightly higher ratio of fats and carbohydrates per serve.
Another difference to consider is the lactose content, Bulk Nutrients’ Whey Protein Isolate contains the least lactose with approximately 1.2g per 100g of powder while Whey Protein Concentrate has approximately 8.6g per 100g of powder.
