A Friend of Yours Loads Up on Vitamin C Once

A friend of yours loads up on vitamin C once a week instead of spacing it out over time. She argues the convenience of not having to take pills every day. What advice do you have for her?

A) Her body has no way of storing excess vitamin C, which is water soluble and passes right through.
B) Because vitamin C is not soluble in water, excess is stored in fat, and could be toxic.
C) She would get more benefit from large doses once a month.
D) Don't take vitamin C because you get it in the food you eat.
