Zinc: A Very Precious Metal Research into zinc's importance has identified several ben-

eficial mechanisms through which zinc, a group 2B metal, can act on the human body:

• Antioxidant properties, protecting cells from damage by free radicals

• Stabilizes organelles, structures within a cell that control functions like growth and energy production

• Anti-apoptotic agent, protecting cells from death • Important cofactor in the synthesizing of DNA strands • Vital component of wound healing • Anti-inflammatory agent These vital functions make zinc supplementation important

for anyone facing illness. For asthmatics and sufferers of respira- tory tract infections, zinc may be one of your best dietary defen- sive strategies.

Zinc for Respiratory Health A 2021 study, published in the journal BMJ Global Health,

identified acute respiratory tract infections (ARIs) as a leading cause of illness and death worldwide. Meta-analysis of random

effects of zinc supplementation were conducted to estimate the pooled effects of supplements of vitamins D and C, zinc and multiple micronutrients (MMS) on the occurrence of ARIs and the duration of ARI symptoms. Results of multiple studies showed that vitamin D supple-

mentation reduced the risk of ARI and shortened duration of symptoms by a value of -6%. Vitamin C had the same effects to a degree of -9%, with a greater effect among men than women, and in middle-income countries compared to high-income countries. While zinc in isolation did not reduce the risk of ARIs, it significantly decreased the duration of ARI symptoms. Takeaways from this important micronutrient study spotlight the need for a varied, vitamin-rich diet and regular sun exposure or a high-quality, bioavailable supplement combining vitamins C and D with zinc and essential micronutrients for the greatest degree of protection for your lungs and airways. Ingesting too much zinc also carries risks; taking oral zinc

in high doses over long periods may lead to copper deficiency. Symptoms of low copper levels include numbness and weakness in your extremities. The National Institutes of Health considers supplementation at 40 milligrams of zinc per day to be the upper limit for adults.
