Label is clear about dosing and the bottle doesn't take up much shelf space. Clean ingredient list with no fillers I didn't recognize — exactly what I look for.

Mixes clean with just a shaker bottle — no clumps and no grit at the bottom. Saw a real difference in my hair and nails within a month — not placebo, measurable.

Saw a real difference in my hair and nails within a month — not placebo, measurable. Mixes clean with just a shaker bottle — no clumps and no grit at the bottom. Cost per serving is lower than my old brand and the quality is at least as good. Scoop was buried at the very bottom — minor, but annoying out of the gate.

Zero clumping, which I appreciate since my old one needed a whisk every time. No proprietary-blend nonsense, just clearly dosed ingredients.

No upset stomach, no jitters, just a solid product that does what it claims.

Does what it says without any of the fillers I see in other brands. Will be a staple in my cabinet.
