Analysis

Calcium ascorbate supplies 1,000 mg vitamin C in a buffered form along with 100 mg calcium. The formulation suits people who want a high-dose vitamin C tablet with less acidity than plain ascorbic acid.

Citrus bioflavonoids at 250 mg add meaningful formula breadth. Acerola and rutin are only 50 mg each, so they should be treated as supporting additions rather than primary reasons to buy it.

Ninety one-tablet servings and a low serving cost create strong practical value. Acerola concentration, rutin purity, inactive ingredients, and full usage details are not included in the supplied data.

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

92 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 lacks a stated concentration or vitamin C yield. Calcium ascorbate provides the dominant vitamin C amount, leaving acerola as a minor addition. Although the serving is inexpensive, its cost per meaningful acerola weight is unfavorable.
