Pros & Cons
Pros
- Uses USP Grade L-Ascorbic Acid, a well-studied and effective form of Vitamin C.

- Simple, single-ingredient formula without unnecessary fillers or additives.
- High dose (1000 mg) is more than enough to meet daily requirements for immune and antioxidant support.

- Megadoses of Vitamin C have limited evidence for preventing colds in the general population, though they may slightly shorten the duration.
- May increase the risk of kidney stones in people who are prone to them.
