Product analysis

56 out of 100

Buffered Vitamin C 500 mg provides vitamin C to support normal immune function and collagen formation, particularly when intake is low. The extra flavonoids and rutin do not establish an added benefit.

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

Nutrient Quality33

Vitamin C and calcium are identified as calcium ascorbate, but that does not establish an extra health benefit. The forms of the added flavonoids and rutin are not disclosed.

Ingredient Transparency81

All listed ingredient amounts are disclosed. The vitamin C source is clear, while the flavonoid and rutin forms are missing.

Value For Money41

Vitamin C offers moderate value for the amount provided. Rutin is relatively costly at the whole-product price, and the other ingredients do not establish extra value.

Customer Satisfaction79

Customer ratings are positive across several hundred reviews. The larger review pool gives useful context for satisfaction.

Product Focus64

Vitamin C provides the main connection to immune function, collagen formation and antioxidant nutrition. The additional ingredients do not establish broader benefits, and extra vitamin C may add little when intake is already adequate.

Ester-C with Citrus Bioflavonoids

American Health

A substantial buffered vitamin C amount and a clearly disclosed bioflavonoid portion provide more ingredient depth than the original. Rutin is not separated, but the delivery remains aligned with stomach comfort.

86 Performance

Ester-C Plus 1000 mg Vitamin C

Solgar

Buffered vitamin C doubles the core amount and pairs it with citrus bioflavonoids in a simple formula. It improves potency while preserving stomach-comfort potential, although separate rutin is absent.

86 Performance

C

Swanson

Fully buffered calcium ascorbate doubles the vitamin C amount and keeps a focused citrus bioflavonoid addition. The original provides separate rutin, but this option has a clearer high-potency core.

80 Budget

Supreme C Complex

Swanson Premium Brand

The same vitamin C amount comes with twice the citrus bioflavonoids and more rutin at a lower serving cost. Standard unbuffered ascorbic acid may be less comfortable than the original’s calcium ascorbate.

84 Budget

Ester-C 500 mg With Citrus Bioflavoinds

American Health

Buffered Ester-C and substantial citrus bioflavonoid support offer stronger value and preserve expected stomach comfort. The label’s repeated bioflavonoid entries make the actual breakdown less clear than the original.

84 Budget

Ester-C 24 Hour Immune Support 1000 mg

NatureSmart

A buffered vitamin C form supplies a larger core amount with citrus bioflavonoids at lower serving cost. Separate rutin is not disclosed, but the focused formula retains the original’s stomach-friendly intent.

82 Value

Ester-C Plus 1000 mg Vitamin C

Solgar

A substantial buffered vitamin C serving with bioflavonoids, acerola, rose hips, and rutin offers strong long-term value. The plant additions are modest, but both potency and supporting breadth exceed the original.

84 Value

Ester-C 1000 mg With Citrus Bioflavonoids

American Health
