Metagenics
Ultra Potent-C 1000 Vitamin C (90 Tablets)
Amazon page snapshot accessed 2026-10-12. Prices and ratings are not live; check the listing for updates.
Best for: A buffered, high-strength vitamin C that's easier on the stomach
Our take
Metagenics is a practitioner-channel brand, and this is its high-strength vitamin C: 1,000 mg per tablet in a buffered form the label describes as gentle on the stomach, plus small amounts of L-lysine, citrus bioflavonoids and L-glutathione. One tablet a day makes the 90-count bottle a three-month supply. It costs more than basic vitamin C, and 1,000 mg is well above the daily requirement, so it's a choice for people who specifically want a high-dose buffered formula.
