Talk with your oncologist about whether vitamin C is safe for you.
Who Should Avoid Vitamin C Supplements
Vitamin C isnt safe or appropriate for everyone.
The good news is that vitamin C-rich foods have a much lower risk of medication interactions than supplements.
How Much Vitamin C Is Safe per Day?
The recommended daily allowance (RDA) for vitamin C is based on age and sex.
Because smoking increases oxidative stress, people who smoke should consume an additional 35 mg per day.
When in doubt, speak with a health care professional.
The Bottom Line
Vitamin C is an essential nutrient with many health benefits.
However, it isnt safe for everyone, especially when taken in supplement form.
