Does Tea Affect Vitamin C?

May affect absorption or how you feel

The short answer

Tea polyphenols can oxidize ascorbic acid (vitamin C) in the gut, reducing its bioavailability. However, vitamin C can also counteract tannin-mineral binding.

How to arrange timing

Separate vitamin C from tea by 1 hour for optimal absorption.
