Analysis

Calcium ascorbate provides 1,000 mg vitamin C with 100 mg calcium in a buffered form. The substantial serving suits users deliberately choosing high-dose vitamin C rather than a food-level amount.

Citrus bioflavonoids add 250 mg, while acerola and rutin contribute 50 mg each. Those smaller ingredients broaden the label but do not make this a focused acerola or rutin supplement.

The 180-serving container and low serving cost are major practical advantages. Acerola concentration, rutin purity, inactive ingredients, and detailed use information are not supplied.

Who is it for
  • Regular high-dose vitamin C users
  • People seeking a large value-size bottle
  • Adults who prefer buffered vitamin C
Best for
  • Long-term vitamin C supplementation
  • Less-acidic vitamin C intake
  • One-tablet daily routines

  • Offers 180 servings
  • Very low serving cost

Cons

  • Acerola contributes only 50 mg
  • Rutin amount is modest
  • No acerola standardization is given

Nutrient quality

82 Highest impact

Calcium ascorbate is a well-tolerated buffered vitamin C form, while the small botanical additions lack potency details. Vitamin C is substantial, but acerola and rutin are too small for focused support.

Ingredient transparency

81 Highest impact

Every listed active ingredient has an individual amount. Excipients and daily directions are absent from the supplied data, which leaves some label details uncertain.

Customer satisfaction

71 High impact

The aggregate satisfaction average is strong, though no detailed feedback is supplied. The large volume provides a stable aggregate satisfaction signal.

Value for money

93 Highest impact

A strong buffered vitamin C dose supports good formula quality despite token botanical additions. The serving offers excellent cost efficiency for the core vitamin C amount.

Report overview
Rutin (Sophora japonica) · 50 mg OverallScore61
B- Active Ingredient Quality & BioavailabilityD- Dose, Safety & Label TransparencyB Value

Sophora japonica clearly identifies the rutin source, while the generic powder lacks purity details. The disclosed dose remains too low for targeted capillary support but offers favorable cost per active amount. The high vitamin C dose may cause stomach upset or diarrhea in sensitive users despite its buffered form.

Acerola · 50 mg OverallScore24
F Active Ingredient Quality & BioavailabilityD- Dose, Safety & Label TransparencyF Value

The 50 mg acerola powder dose is low and does not disclose a concentration ratio or vitamin C standardization. Most vitamin C comes from calcium ascorbate, so the formula is not primarily a natural acerola source. A low serving cost does not offset the weak amount delivered per unit of acerola.
