Consuming both a multivitamin with 60 mg of
vitamin C and a collagen supplement with an additional 60 mg of vitamin C in a day is generally safe.
The RDA for vitamin C for adults is 75 mg/day for women and 90 mg/day for men.
A combined dose of 120 mg/day (from your supplements) is within safe limits.
Next Steps
If you experience any unusual side effects (e.g., stomach upset), consult.
Health Tips
If your diet already includes plenty of
vitamin C-rich foods (e.g., citrus fruits, bell peppers, strawberries), monitor total intake to avoid excessive amounts.
