Consistent quality across every tub I've bought so far. Arrived sealed and well packaged, with a scoop that was actually easy to find. Saw a real difference in my hair and nails within a month — not placebo, measurable.

Consistent quality across every tub I've bought so far. Arrived sealed and well packaged, with a scoop that was actually easy to find. 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. Finally one that doesn't taste artificial. The vanilla is subtle and pleasant.
Started noticing better recovery after about two weeks of consistent use. Label is clear about dosing and the bottle doesn't take up much shelf space.
Zero clumping, which I appreciate since my old one needed a whisk every time. Smooth flavor with no weird aftertaste, which is rare in this category. The price-to-quality ratio here is hard to beat; I've already reordered twice.
Good value compared to what I was paying before, and the quality is at least as good if not better.
Gentle enough to take daily and I've had zero side effects. Exactly what I was hoping for.
