Question 1

Is whey isolate better than whey concentrate?

Accepted Answer

Whey isolate is higher in protein by weight and lower in lactose, fat, and carbohydrate. Whey concentrate is usually less expensive and can build muscle just as effectively when equal amounts of protein are consumed.

Question 2

Does whey isolate contain lactose?

Accepted Answer

Whey isolate normally contains much less lactose than concentrate, but it is not guaranteed to be lactose-free. Check for a specific lactose-free claim if you have significant intolerance.

Question 3

Is whey concentrate bad for weight loss?

Accepted Answer

No. Whey concentrate can fit into a calorie deficit as long as its calories are included in your daily intake.

Question 4

Does whey concentrate cause bloating?

Accepted Answer

It can cause bloating in someone who has difficulty digesting lactose, but sweeteners, gums, serving size, and the liquid used in the shake may also contribute.

Question 5

Is whey isolate dairy-free?

Accepted Answer

No. Whey isolate comes from milk and contains milk protein, even when very little lactose remains.

Question 6

Is whey isolate worth the extra money?

Accepted Answer

It may be worth the cost if lower lactose or a higher protein-to-calorie ratio solves a specific problem. If you tolerate concentrate and the labels are otherwise similar, isolate is unlikely to produce better muscle-building results.
