Typically, people with suboptimal zinc levels experience symptoms of low immunity, impaired wound healing, skin conditions, and poor taste function. However, these are only the most well-known signs of zinc deficiency. The role of zinc in overall health is much more complex.
Zinc's reputation as an immune-boosting mineral is well-deserved, as it is necessary for the normal development and function of natural killer cells, neutrophils, macrophages, and various cytokines. Research has shown that it can inhibit viral replication in the upper respiratory tract, making it particularly useful for colds and other infections.
When it comes to hormonal balance, zinc helps stabilize insulin and thus regulate blood sugar. It is also involved in thyroid health by increasing the sensitivity of triiodothyronine (T3) receptors. Finally, in men, zinc deficiency can negatively affect sperm parameters and is one of the few nutrients shown to contribute to low testosterone levels.
Other clinical conditions where zinc supplementation has been shown to be beneficial include eating disorders, age-related macular degeneration, and oligospermia. Populations with greater zinc needs include the elderly, people with digestive disorders, vegetarians, pregnant women, and people taking multiple prescription medications.
Vitamin C has similar responsibilities to zinc in the body. For example, vitamin C plays a vital role in the maintenance of connective tissue, wound healing, and proper immune function. Like zinc, vitamin C is commonly used as a stand-alone treatment to reduce the severity and duration of the common cold. Despite its critical importance for optimal health, the human body cannot synthesize vitamin C, and dietary sources are required to maintain adequate levels.
Cyto.Matrix Zinc Citrate provides 50 mg of elemental zinc in the well-absorbed and tolerated citrate salt form, with an additional 400 mg of vitamin C per capsule. These two nutrients have been studied in combination for the common cold and have been shown to significantly and rapidly reduce rhinorrhea. The added vitamin C in Cyto.Matrix Zinc Citrate also ensures adequate acidity for optimal absorption and tolerance of high-dose zinc in the citrate salt form.
