Is taking a multivitamin b complex and a vitamin C supplement unhealthy if the multivitamin also contains vitamin c?

Answer 1

== == No; one can safely take both supplements. However, vitamin C can cause a copper deficiency with prolonged high doses (more than 20 times the Recommended Daily Allowance (RDA) for months, for example). Unless you are taking extremely high-dose supplements, you are not likely to have this problem. Additionally, vitamin C intake levels above the RDA have not shown any additional benefit in controlled experiments. Unless there is some indication that your intake of vitamin C is deficient, it is likely that you will not benefit from the additional vitamin C supplement.

Answer 2

Taking a multivitamin b complex and a separate vitamin C supplement in addition to a multivitamin that already contains vitamin C is unlikely to be harmful in the short term, but could lead to excessive intake of these nutrients over time. It's generally best to check with a healthcare provider to ensure you are not exceeding safe upper limits for these vitamins.
