What to know before buying
Listing details to confirm
The listing gives conflicting protein figures: 12 g and 25 g, while its feature text specifies 25 g per serving. It also gives vitamins and minerals as “1.6, 1.6 milligrams” without clarifying what the figures refer to. Confirm the current serving nutrition and label before relying on these details. The description states under 210 calories per serving, while the highlights specify 204kcal. Customer feedback is mixed on how filling it is, with some finding it too filling.
Who is it for?

Customer feedback reports appetite control and feeling full until lunch, with positive comments about creamy texture and mixing the powder with fruit or peanut butter. The feedback also indicates that the filling effect is not ideal for everyone, as some find it too filling. This matters if you want a substantial meal replacement rather than a lighter drink. The listing describes a high-protein shake, but its protein figures conflict, so customer impressions do not resolve the nutrition details.
Positive themes
- Customers report that it helps curb appetite and keeps them full until lunch.
- Customers describe a creamy texture and say it blends well with fruit and peanut butter.
Mixed feedback
- Some customers find the shake satisfyingly filling, while others say it can be too filling.
