Zero clumping, which I appreciate since my old one needed a whisk every time. Saw a real difference in my hair and nails within a month — not placebo, measurable.

For what you pay, the ingredient quality is excellent. Sleep quality went up almost immediately, which is exactly what I wanted. You can tell this is a quality formulation; transparent labeling and third-party tested.

Does not dissolve well — I end up chewing little lumps, which is unpleasant. Ingredient list has more fillers than I'd like for the price. Packaging felt flimsy and one tub arrived slightly dented.

Started noticing better recovery after about two weeks of consistent use. Arrived sealed and well packaged, with a scoop that was actually easy to find. Dissolves completely in water, even without a blender. Ingredient list has more fillers than I'd like for the price.

Finally one that doesn't taste artificial. The vanilla is subtle and pleasant. Consistent quality across every tub I've bought so far. Great value for the serving count — works out cheaper per dose than the big brands.

My second tub now. Quality has been identical between orders, which I really appreciate.
