What reviewers say

Healthline picked it for active people thanks to the NSF certification; the tester noted a faint citrus taste and no stomach upset, but flagged the cost and the monk fruit. A dietitian-written Healthline roundup praised its ingredients and certification, again naming cost as the drawback. BarBend mentions it briefly as a powder that includes its own scoop.
