About this product

Calcium ascorbate provides 1,000 mg vitamin C, with a large 500 mg citrus bioflavonoid complex. Grape-seed polyphenols at 100 mg add a second clearly defined antioxidant component.

Rutin is supplied at 50 mg, while acerola and rose hips are only 10 mg each. Those small additions do not make the formula a meaningful natural-source acerola product.

Two capsules per serving and 90 servings provide convenient long-term use. The serving cost is much higher than simpler buffered vitamin C options, and inactive ingredient details are absent.

Who is it for
  • Adults seeking vitamin C with high bioflavonoid content
  • People wanting grapeseed polyphenols alongside vitamin C
  • Users who prefer capsules

Warnings

Product analysis

68 out of 100
Buffered vitamin C, citrus flavonoids, and grapeseed form a strong antioxidant blend. Token acerola and higher cost are notable drawbacks.

AI assessment of the formula, label and price. How scoring works

Nutrient quality78

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 transparency79

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 satisfaction64

The aggregate satisfaction average is exceptionally strong, though no detailed feedback is supplied. The small volume limits confidence in the aggregate satisfaction signal.

Value for money45

A strong buffered vitamin C dose supports good formula quality despite token botanical additions. The serving cost is high compared with other buffered vitamin C formulas.
