Saw a real difference in my hair and nails within a month — not placebo, measurable. Dissolves completely in water, even without a blender. Label is clear about dosing and the bottle doesn't take up much shelf space. The taste is the dealbreaker for me — way too artificial and lingers for hours.

Mixes clean with just a shaker bottle — no clumps and no grit at the bottom. For what you pay, the ingredient quality is excellent. You can tell this is a quality formulation; transparent labeling and third-party tested. Gave me some stomach discomfort, so I had to stop before I could judge results.

The taste is the dealbreaker for me — way too artificial and lingers for hours. Not worth the premium — comparable products cost less per serving.

Packaging is sturdy and the freshness seal was fully intact on arrival. Finally one that doesn't taste artificial. The vanilla is subtle and pleasant.

No proprietary-blend nonsense, just clearly dosed ingredients. Cost per serving is lower than my old brand and the quality is at least as good. Needs a blender to mix properly, a shaker just doesn't cut it.

Cost per serving is lower than my old brand and the quality is at least as good. Clean ingredient list with no fillers I didn't recognize — exactly what I look for. Resealable tub keeps everything fresh and the scoop sits right on top.
