Vitamin C is good for reducing histamines and helps decrease and thin mucus. TwinLab Allergy C is a great one if you are not allergic to Palm. Just find a Vitamin C that is from a source you are not allergic and also if you have had viral problems take Natures Way Sambucus, there are several clinical studies showing the Sambucus/Sambucol to work as well and in some studies even better than prescription anti-virals, and it is effective against a wider range of viral strains. Few things reduce cytokines which can cause excess mucus and inflammation, but Vitamin E has helped in many cases to reduce cytokines, however do not take over 400 IU's. Vitamin E also reduces blood pressure in many people but taking over 400 IU's can actually increase blood pressure in some individuals where the lower dose decreased bp, not sure why that is but it is good to be aware of if you are going to be taking it for cytokine reduction.
Hi, are you referring to Zinc? Zinc is necessary for the functioning of more than 300 different enzymes and plays a vital role in a large number of biological processes. Its immune-enhancing activities include regulation of T lymphocytes, CD4 cells, natural killer cells, and interleukin-2. In addition, it has been claimed that zinc possesses antiviral activity. Zinc has been used since ancient Egyptian times to enhance wound healing. But you should take it cautiously as sometimes people have an allergic reaction to Zinc. Regards.
