Overview
Integrative Therapeutics Buffered Vitamin C delivers 1,000 mg of vitamin C per serving in vegan capsules, buffered with added magnesium and calcium. It is gluten free and packaged as a 60 capsule bottle for daily immune and antioxidant support.
Buffering vitamin C with calcium and magnesium ascorbate is meant to soften the acidity that plain ascorbic acid can cause at higher doses. The vegan capsule keeps it usable across most diets, though there is no chewable or liquid version in this line.
- 1,000 mg buffered vitamin C per serving
- 60 vegan capsules
- Contains added magnesium and calcium
- Gluten free formula
Who it's for
Best suited to adults who want a daily 1,000 mg vitamin C but find plain ascorbic acid harsh on the stomach. Not the pick for anyone who wants a chewable, gummy or liquid format instead of a capsule.

Performance notes
Buffering pairs the vitamin C with mineral ascorbates such as magnesium and calcium, the standard way supplement makers reduce the stomach acidity linked to plain ascorbic acid at higher doses, while still delivering a full 1,000 mg per serving.
