Analysis

Three named fish sources provide hydrolyzed collagen, and vitamin A plus biotin add related tissue-support nutrients. Even so, the combined collagen amount is small and unlikely to provide the structural depth expected from a dedicated collagen supplement.

Pantothenic acid is prominent, while several botanical ingredients are hidden inside a blend. The formula is aimed more at hair support than its listed skin and vision goals, and it lacks the broader eye nutrients found in dedicated vision products.

Fo-ti is the most important limitation because it has been associated with liver injury. Fish collagen also makes the tablets unsuitable for people with fish allergy, while collagen type and amino acid details are not supplied.

Who is it for
  • Adults seeking a broad hair-oriented botanical formula
  • People comfortable with fish-derived collagen
  • Users who can review fo-ti suitability with a clinician
Best for
  • Basic vitamin A and biotin coverage
  • Users prioritizing tablets over collagen powder
  • Short-term hair-support experimentation with supervision

Pros

  • Fish species are identified
  • Hydrolyzed collagen form
  • Practical vitamin A amount
  • Biotin is clearly quantified

Cons

  • Collagen amount is very small
  • Collagen type is not disclosed
  • Botanical blend hides ingredient amounts
  • Weak fit for targeted vision support

Warnings

  • Fo-ti has been associated with liver injury; avoid it with liver disease or other potentially liver-stressing products unless medically supervised.
  • Fish collagen makes the formula unsuitable for people with fish allergy.
  • Preformed vitamin A should be counted with other retinol sources, particularly during pregnancy.

Nutrient quality

58 Moderate impact

Hydrolyzed fish collagen and several hair-related nutrients provide a coherent base. The collagen amount is low, while opaque botanicals and fo-ti weaken confidence in the formula.

Ingredient transparency

42 Lower impact

Several nutrients and collagen sources are identified with amounts. A proprietary botanical blend, a zero-quantity fo-ti entry, and missing non-active ingredients leave important uncertainties.

Customer satisfaction

57 Moderate impact

The supplied satisfaction metric is strong and response volume is limited. Specific firsthand feedback was not supplied, so recurring complaints and purpose alignment remain uncertain.

Value for money

47 Lower impact

The serving cost is moderate, but low collagen potency and an opaque botanical blend weaken quality-adjusted value. More focused and transparent alternatives are likely to offer better category value.

Collagen · 125 mg

Hydrolyzed fish collagen gives the formula direct structural relevance, but its amount is far below typical gram-level peptide servings. Vitamin A adds cell-maintenance support without overcoming the weak collagen dose.

Collagen sources are named, while type and amino-acid details are absent and the botanical blend is proprietary. People with fish allergy should avoid the fish collagen, and fo-ti has been associated with liver injury.

Report overview
F Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyB- Value

Retinyl acetate provides only preformed vitamin A, which is less self-regulating than carotenoids. The dry format lacks a lipid carrier, so absorption depends on food. The 2,500 IU serving falls within the preferred efficacy and safety range, and the broader multinutrient formula supports fair value despite modest vitamin a efficiency.

C+ Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyF Value

Hydrolyzed fish collagen is used, but the amount is too small for meaningful structural support. The product omits collagen type, protein matching, and an amino-acid profile while carrying a high collagen-specific cost. Fish collagen may be unsuitable for people with fish allergy, and the included fo-ti extract has been associated with liver injury.
