Pros
- +Exceptionally well-tolerated — most reviewers report no stomach acidity or discomfort, even taken on an empty stomach
- +Clean, minimal formula: pure ascorbic acid, hypromellose capsule, magnesium stearate — nothing unnecessary

- -No independently verified third-party testing confirmed by product specs, despite iTested claims on packaging
- -60-capsule size lasts only two months at one daily — higher per-unit cost than the 240-capsule option
- -A handful of reviewers note the capsules run on the larger side, though most find them manageable
Best For
Watch Out
