What to know before buying

Listing details to confirm

The listing says 14 servings in the title, while its product description also refers to six fruit flavors. The flavor count does not confirm how many flavors are included in this container. Its low-carb and no-added-sugar claims do not mean low-calorie, and the FAQ separately states 90 calories without a serving nutrition panel in the supplied details. Customer feedback also varies on stomach comfort, effectiveness, mixability and value, so individual experience may differ.

Who is it for?

A good fit for

People who prefer a fruit-flavored protein drink mixed with water over a creamy shake.
Buyers seeking a whey-isolate powder with a stated 20g of protein per serving.
Those looking for a gluten-free product with listing claims of no artificial sweeteners and no added sugar.

Less suited to

Anyone who needs uniformly positive feedback about taste or a guaranteed smooth, quick dissolve.
People avoiding whey or seeking a plant-based protein powder.
Buyers requiring a confirmed low-calorie product. The listing explicitly says it is not a low-calorie food.

Customer feedback is favorable about the protein content and ease of mixing for some, but reports are mixed on taste, effectiveness, value and dissolving. Some customers describe a bad aftertaste or slow dissolution, and stomach comfort is not consistent, with some reporting nausea. That variability matters for a powder intended to be shaken into water, even though the listing claims easy mixing. The aggregate rating distribution is generally favorable but includes a meaningful range of lower ratings, so it does not establish consistent taste or tolerance.

Positive themes

Customer feedback includes positive mentions of the stated protein content.

Negative themes

Some customers report an unpleasant aftertaste.
Some customers report slow dissolving, and some describe nausea.

Mixed feedback

Taste, effectiveness, mixability, dissolvability, value and stomach comfort receive mixed feedback.
