  • Includes hyaluronic acid for hydration
  • Clean ingredient profile
  • Once-daily capsule

Cons

  • Relatively expensive

  • Consult a professional if taking other biotin supplements

Nutrient quality

89 Highest impact

High-quality ingredients like sodium hyaluronate and a robust keratin dose effectively support structural integrity for hair and nails. While the hyaluronic acid dosage appears lower than some clinical benchmarks, the overall synergy of the selected nutrients aligns well with beauty-focused health goals.

Ingredient transparency

98 Highest impact

Complete disclosure of ingredient quantities and the absence of proprietary blends ensure that the user knows exactly what is being consumed. Clear serving instructions and specific chemical names like sodium hyaluronate contribute to a high level of label clarity.

Customer satisfaction

91 Highest impact

Strong average ratings and a substantial review count indicate consistent satisfaction among users seeking hair and nail support. Feedback generally aligns with the intended beauty outcomes, suggesting the formula performs reliably for its target audience.

Value for money

67 High impact

A relatively high cost per serving reflects premium branding rather than an exceptionally complex or unique ingredient profile. While the dosages of biotin and keratin are meaningful, the price point remains less competitive compared to similar beauty-focused supplements.
