Whey isolate and whey blend are two different types of whey protein supplements.
Whey isolate is a type of whey protein that undergoes further processing to remove most of the fat and lactose, resulting in a protein powder that is over 90% pure protein. Whey isolate is often considered the purest form of whey protein and is ideal for those who are lactose intolerant or have trouble digesting regular whey protein.
Whey blend, on the other hand, is a combination of different types of whey protein, usually whey protein isolate and whey protein concentrate. This blend provides a more balanced amino acid profile, with both fast-acting and slow-digesting proteins. Whey blend supplements are ideal for those who want a combination of fast and slow-digesting proteins for optimal muscle growth, recovery, and repair.
In summary, whey isolate is ideal for those who want a pure, high-protein supplement with little or no fat or lactose, while whey blend is ideal for those who want a more balanced amino acid profile and a combination of fast and slow-digesting proteins. Ultimately, the choice between whey isolate and whey blend depends on individual goals, preferences, and dietary restrictions.
