No proprietary-blend nonsense, just clearly dosed ingredients. Cost per serving is lower than my old brand and the quality is at least as good. Label is clear about dosing and the bottle doesn't take up much shelf space.

No proprietary-blend nonsense, just clearly dosed ingredients. Cost per serving is lower than my old brand and the quality is at least as good. Label is clear about dosing and the bottle doesn't take up much shelf space.
The price-to-quality ratio here is hard to beat; I've already reordered twice. Dissolves completely in water, even without a blender.
Cost per serving is lower than my old brand and the quality is at least as good. 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.
Great value for the serving count — works out cheaper per dose than the big brands. Packaging is sturdy and the freshness seal was fully intact on arrival. Honestly tastes like a treat rather than a chore.
Saw a real difference in my hair and nails within a month — not placebo, measurable. For what you pay, the ingredient quality is excellent. The seal was broken on arrival, which made me nervous about freshness.
