Saw a real difference in my hair and nails within a month — not placebo, measurable. Label is clear about dosing and the bottle doesn't take up much shelf space. Ingredient list has more fillers than I'd like for the price.
You can tell this is a quality formulation; transparent labeling and third-party tested. Saw a real difference in my hair and nails within a month — not placebo, measurable.
Dissolves completely in water, even without a blender. No proprietary-blend nonsense, just clearly dosed ingredients. Packaging is sturdy and the freshness seal was fully intact on arrival.
Started noticing better recovery after about two weeks of consistent use. Finally one that doesn't taste artificial. The vanilla is subtle and pleasant. Clean ingredient list with no fillers I didn't recognize — exactly what I look for.
Sleep quality went up almost immediately, which is exactly what I wanted. Blends smooth in seconds; texture is consistent every scoop.
I've been using this for about six weeks and noticed a real difference in my recovery. Will keep reordering.
