Kirkland Whey Protein Gains Fans for Quality and Value, But Additives Raise Concerns

by Shreeya

If you’re curious about how shoppers feel about whey protein at Costco, the Costco subreddit is one of the best places to find candid opinions. Recently, a Reddit user asked for thoughts on Kirkland’s chocolate whey protein powder, sparking hundreds of responses.

The majority of comments were positive, with roughly three-quarters of users praising the product. Many highlighted its affordability and versatility. One user wrote, “Its price per pound is top tier… I started mixing it into my cold brew in the mornings.

Now it tastes like an iced mocha and has tons of protein. It’s great.” This shows whey protein isn’t just for shakes—it can easily be incorporated into everyday beverages.

Some users raised concerns about the powder’s use of sucralose and other additives. Several suggested alternatives like Ascent protein, which is offered at Costco and contains fewer ingredients. One commenter noted, “It tastes fine but has a LOT of unneeded junk in it. The Ascent powder is miles better if you want a decent protein powder with minimal ingredients.”

Of course, Reddit’s sense of humor shone through, with jokes like, “I like the whey it tastes,” adding some levity to the discussion.

Overall, Kirkland’s chocolate whey protein is winning fans for its taste, value, and versatility, though some health-conscious buyers may prefer options with cleaner ingredients.
