Sleep quality went up almost immediately, which is exactly what I wanted. Clean ingredient list with no fillers I didn't recognize — exactly what I look for. For what you pay, the ingredient quality is excellent. Packaging felt flimsy and one tub arrived slightly dented.

Mixes clean with just a shaker bottle — no clumps and no grit at the bottom. Consistent quality across every tub I've bought so far. Smooth flavor with no weird aftertaste, which is rare in this category. The seal was broken on arrival, which made me nervous about freshness.

There's a chalky, medicinal aftertaste I just can't get past. Does not dissolve well — I end up chewing little lumps, which is unpleasant.

Wish the dosing were more transparent instead of a proprietary blend. The taste is the dealbreaker for me — way too artificial and lingers for hours. Clumps badly no matter how long I shake it; gritty residue settles at the bottom.

Saw a real difference in my hair and nails within a month — not placebo, measurable. The price-to-quality ratio here is hard to beat; I've already reordered twice.

Resealable tub keeps everything fresh and the scoop sits right on top. Sleep quality went up almost immediately, which is exactly what I wanted. Does not dissolve well — I end up chewing little lumps, which is unpleasant.
