Whey Concentrate vs Isolate: What's the Difference and Which to Pick

Short answer: Whey isolate is filtered further than concentrate, so it has a higher protein percentage and less carbohydrate, fat, and lactose per scoop. Concentrate keeps a little more of those and usually costs less. For most people either one works. Isolate is the pick if you are sensitive to lactose or want the leanest macros. The label tells you which you are getting and the grams per scoop.

The difference

• Concentrate: less filtered, a bit more carb, fat, and lactose, usually cheaper.
• Isolate: more filtered, higher protein percentage, less carb, fat, and lactose per scoop, usually a higher price.

How to choose

• Sensitive to lactose, or want the leanest macros: isolate.
• Want solid protein at a better price, and dairy does not bother you: concentrate.
• Many products use both, which is a fine middle ground when the label says so.

What the label should show

• Whether it is concentrate, isolate, or a blend of the two, named plainly.
• Grams of protein per scoop, plus carb, fat, and sugar.
• The serving size, so you know how many scoops that is.
