Clean ingredient list with no fillers I didn't recognize — exactly what I look for. Dissolves completely in water, even without a blender.
Blends smooth in seconds; texture is consistent every scoop. Consistent quality across every tub I've bought so far.
Tastes way better than I expected for a supplement; I actually look forward to taking it. Resealable tub keeps everything fresh and the scoop sits right on top. No proprietary-blend nonsense, just clearly dosed ingredients.
Zero clumping, which I appreciate since my old one needed a whisk every time. Sleep quality went up almost immediately, which is exactly what I wanted. The taste is the dealbreaker for me — way too artificial and lingers for hours.
Consistent quality across every tub I've bought so far. Label is clear about dosing and the bottle doesn't take up much shelf space. Blends smooth in seconds; texture is consistent every scoop. Used it consistently for six weeks and honestly felt no difference at all.
The flavor is genuinely good — not chalky or overly sweet like a lot of others I've tried. Great value for the serving count — works out cheaper per dose than the big brands.
