What the research shows

Zinc is an essential mineral that plays a crucial role in various bodily functions, including immune function, wound healing, DNA synthesis, and cell division. It also acts as an antioxidant, helping to protect cells from damage caused by free radicals.

Reported benefits

• Supports immune function by promoting the production and activity of white blood cells
• Aids in wound healing by supporting collagen synthesis
• May help reduce the duration and severity of the common cold when taken at the onset of symptoms
• Supports reproductive health in both men and women

Who it is for

Individuals who may benefit most from zinc supplementation include those with zinc deficiency, vegetarians/vegans, pregnant or lactating women, individuals with certain health conditions affecting zinc absorption, and those at risk of immune system compromise.

Considerations

It is important to note that excessive zinc intake can lead to adverse effects, such as gastrointestinal upset, copper deficiency, and impaired immune function. Zinc supplements may interact with certain medications, so it is advisable to consult a healthcare provider before starting supplementation, especially for individuals with existing health conditions or those taking medications.
