Question: Zinc Supplements for imunne system boost

 tbarnes42 - Thu Sep 20, 2007 8:54 am

got a quick question. first let me get the fomalities out of teh way. i'm a 33 year old male. no current medical issues.

anyway...i currently take a daily multivitamin. this happens to include 15 mg of zinc (100% daily value). usually in the past when i think i am about to get sick with a cold or something, i start taking zinc supplements to boost my immune system. usually works well...i havent had a "bad" cold in quite some time. the supplements have 50 mg of zinc (333% daily value) 4 month old has a cold...and i don't want to catch it. i was going to start taking the supplements if i started getting any symptoms.

the question is, should i STOP taking the daily mulit-vitamin so i don't OVERLOAD on zinc? is that even an issue? if i took both once a day for a few days (65 mg of zinc) is that unhealthy?

probably a dumb question....just wanted to check.

thanks, Terry

User avatar Hi Tbarnes,

This is actually a great question. Many people assume that since they are vitamins it is better to take more. It turns out that many vitamins can have severe side effects at high doses.

At a dose of 65mg per day for the short term you probably would be OK but it is unlikely you would get any added benefit from the extra dosing.

At levels starting around 150 mg per day in some people toxicities can begin to occur such as a weakened immune system and impairment of normal iron functioning.

I would recommend you simply take the multivitamin with 100% of the recommended daily intake of zinc.

Best wishes.
