Vitamin Megadoses Lower Cholesterol Can An Antioxidant Megadose (not Overdose, But Any OTC "megadose" Vitamin) Cause DNA Damage?

Can an antioxidant megadose (not overdose, but any OTC "megadose" vitamin) cause DNA damage? - vitamin megadoses lower cholesterol

This is one of the things that the famous Dr. Oz, took a day on television, and nobody heard him, as usual, and asked quotations or details. He said he has (up to 10,000 IU of vitamin A in a day compared to the 200% RDA), the antioxidant effect of the real cause of DNA damage.

I searched long and can not progress on this issue - very high doses of vitamin causing DNA damage - with the default search engine on the Internet. If anyone knows the truth about the large amounts of A? (I have not asked a simple vitamin A toxicity, by the way. I am aware.)

Thank you in advance if you can offer assistance.
