Vitamin C-1000
The score explained
evidence, testing and value, weighed before price
Why 6.9 of 10: Provisional: well-established, modest, clearly bounded benefit.
- Good evidence for slightly shorter colds with regular use
- Clear benefit for heavy exercisers
- Very cheap
- Does not prevent colds in normal adults
- Megadosing adds mainly expensive urine
what the evidence says
Vitamin C is one of the most-studied supplements and the verdict is stable: regular supplementation does not reduce how often ordinary adults catch colds, but it modestly shortens duration and severity, and it does reduce cold incidence in people under heavy physical stress like endurance athletes. Taking it only after symptoms start shows little effect. Cheap insurance with well-mapped limits.
Plain-language assessment of the human evidence. No cherry-picked citations.
