Zinc deficiency may contribute to life-threatening inflammation in the face of serious infection. The researchers at Ohio State University used animal models and human cell cultures to study the immune response to infection. They found that when zinc was adequate, the innate immune response was effective but did not get out of control. When zinc levels are too low, however, the immune reaction may run amok and lead to excessive inflammation that could be deadly. This might also help explain why zinc may be helpful against the common cold.The scientists posit that about 40% of elderly Americans may suffer from zinc deficiency because they get too little red meat and shellfish in their diets.

    back in the 40s when my cat would be hurt from a cat fight, my mother would put zinc oxide cream on the wounds. WORKED Also for humans.

    My gynecologist suggested taking zinc a number of years ago to help with canker sores. It did work, too. I don’t get one very often.
    I still take it pretty much daily. I rarely get a cold.
    Did zinc help that? I don’t know or care.

    I used to take a regular Zinc pill every day for more than a year. This was the only supplement, no other minerals or vitamins. I had a minor stroke, my Dr said I should take aspirin instead of zinc. I don’t know if zinc has anything to do with increasing blood clot formation.

    Would zinc supplements help with 88 yo male with foley catheter, has new bladder infection, first one. Being treated with antibiotics, would zinc help?
    Thank you
    PEOPLE’S PHARMACY RESPONSE: Afraid we do not know. The research does not indicate that it is helpful for all patients.
