I have just returned from two days in Quebec City (sigh, it's so
beautiful) and there are about 10 Lactnet digests on the email.  If this
has already been answered, please ignore.

Zinc is already in breastmilk and is important for the baby's nutrition.
But it is unlikely that 50 mg of zinc a day will do much to the levels
in the breastmilk.  Most of the extra will not be absorbed by the baby
in any case.

I doubt that zinc does much to prevent colds as well, unless the mother
is already deficient, and even then.
