Zinc is an essential mineral having a role in the maintenance of the body's nervous and immune systems (T-cell function). This mineral is involved in the biochemical reactions as an antioxidant in the healing process and develops normal tissues Zinc is a cofactor in enzymatic reactions such as protein synthesis polymerases and in carbonic acid anhydrase.

Zinc maintains the body's alkaline balance. Zinc finger, a structural domain found in many gene-regulatory proteins, is a component of hydrophobic hormones acting stabilizing the biomembrane structures and cell membrane metabolism. Zinc deficiencies may result in prolonged wound healing, delayed sexual maturation, mental lethargy, skin changes, and susceptibility to infections. Gluconate and citrate forms are mainly used as zinc supplements. They are easily absorbed by the body. Zinc citrate can be formulated in pharmaceuticals, and foods as a zinc supplement. Zinc citrate is used as an ingredient to treat common cold and various hygienic products. Zinc inhibits the growth of bacteria in the throat and can be used in toothpaste.

Zinc is well known for its reported ability to reduce the length and severity of colds; it can also help alleviate canker sores, sore throats, and skin injuries, acne, tinnitus--or ringing in the ears--and eye problems.

It is also believed effective in fighting auto-immune and inflammatory diseases, such as rheumatoid arthritis, lupus, and fibromyalgia.

While there is no cure for the common cold, the benefits of zinc citrate could bring quicker relief. Tinnitus is annoying at the very least, and zinc, if effective in relieving it, should be an option. Only you and your physician or health care provider can know whether you would benefit from the use of this supplement.
