What Is Whey Protein Isolate
Whey protein isolate is a popular supplement. It is used by athletes and fitness enthusiasts. It helps in muscle building and recovery.
It is made from whey, which is a by-product of cheese. Whey protein isolate is highly processed to remove fat and lactose.
Source And Production
Whey protein isolate comes from cow’s milk. Milk contains two types of protein: casein and whey. Whey is separated during cheese production.
After separation, whey is filtered to remove fats and lactose. This results in a high-protein powder. The process ensures whey protein isolate is low in fat and carbs.
- Derived from cow’s milk
- Filtered to remove fats and lactose
