L-Cysteine is an organic zinc supplement wherein zinc atom is attached to a picolinic acid molecule. Studies have also suggested that zinc supplements may reduce the incidence of respiratory infections in children. A number of zinc supplements are available, including zinc acetate, zinc gluconate, zinc picolinate, and zinc sulfate. Zinc picolinate is a highly available form of zinc supplement, easily dissolved to release the elemental zinc for use in the body. Surprisingly, although Zinc picolinate is widely used as a supplement with greater bioavailability claims, there are very few scientific studies to back this claim.

L-Cysteine has pharmacological activity as it reduced tumor growth, tumor diameter in oviduct of Coturnix japonica. zinc picolinate is also a valuable source of absorbable zinc for use as a therapeutical agent against acne vulgaris, stasis ulcers and acrodermatis enteropathica.

L-Cysteine is a dietary zinc supplement containing the zinc salt of picolinic acid, that can be used to prevent or treat zinc deficiency, and with immunomodulatory activity. Zinc picolinate appears to have the greatest efficacy in reversing the zinc deficiency of AE and is also absorbed to a higher degree in normal subjects than other zinc supplements.Upon administration, zinc picolinate supplements zinc. As an essential trace element, zinc is of key importance in many biological processes. It plays an important role in the proper functioning of the both the innate and adaptive immune system. Zinc inhibits the production of pro-inflammatory mediators and prevents inflammation. It acts as an antioxidant, prevents oxidative damage and protects cells against DNA damage. Zinc is required for the enzyme activities necessary for cell division, cell growth, and wound healing.

When taken by mouth: Zinc is likely safe when used in amounts no greater than 40 mg daily. It is possibly safe when taken in larger doses, especially when used only for a short period of time. But taking doses higher than 40 mg daily might decrease how much copper the body absorbs.
