Many studies have focused on zinc supplements due to their potential beneficial impact on human health. Zinc, a trace mineral found abundantly in the human body, plays a vital role in various physiological processes.

One of the fundamental functions of zinc, which is a component in over 300 enzymes, is that it participates in regulating enzymatic activity in the body. It facilitates and enhances the proper functioning of these enzymes.

These zinc-backed enzymes play critical roles in DNA synthesis and protein synthesis, and contribute significantly to the overall maintenance and regulation of vital cellular processes.

Popping zinc supplements can provide you with a host of other benefits, given that the mineral plays a crucial role in enhancing immune function, stabilizing blood sugar levels, and supporting the health of the skin, eyes and heart.

Notwithstanding the wide range of benefits, zinc supplementation may come with some potential adverse health outcomes, which is why it is essential to take precautions before taking them.

Let's explore the advantages of incorporating zinc supplements into one's diet:

Treat zinc deficiency:

Zinc supplements are commonly utilized to address zinc deficiency, a condition that often affects people with inadequate dietary intake. Since the body cannot produce zinc internally, maintaining a balanced diet becomes crucial for ensuring adequate levels of the mineral.

Zinc deficiency can give rise to a range of symptoms, such as weakened immunity, hair loss, reduced appetite, gastrointestinal issues like diarrhea and impaired wound healing.

A study, published in PubMed in 2021, revealed that zinc supplements can effectively enhance the presence of the essential mineral in the bloodstream.

Improves immune function:

Zinc is commonly included in many over-the-counter medications is because of its ability to enhance the immune system and combat inflammation. It could be the best answer to many infections if taken before the symptoms start to manifest.

A previous study found that zinc lozenges containing 80-92 mg of zinc may reduce the duration of the common cold by up to 33%.

Helps manage blood sugar:

Zinc plays a significant role in the regulation of blood sugar levels and the secretion of insulin, the hormone responsible for transporting sugar from the bloodstream to the body's tissues. Studies have indicated that zinc can help maintain stable blood sugar levels and enhance the body's sensitivity to insulin.

Zinc is known to play a vital role in beta-cell function, insulin activity in the body and glucose homeostasis. Studies have suggested that zinc has the capacity to help regulate blood sugar levels and improve insulin sensitivity in the body.

Improves heart health:

Heart disease is one of the leading causes of death globally and studies have shown that zinc can help cut down on many risk factors associated with cardiac arrests. A study published in PubMed says zinc deficiency may be associated with cardiac failure, and that zinc supplementation may help improve cardiac function in patients with heart failure.

There is little evidence regarding the association between low serum zinc levels and the risk of coronary heart disease, and further research is needed to establish a clear relationship between the two.

Side effects of zinc supplementation

Zinc supplements are generally well-tolerated if the intake doesn't exceed 40 mg per day. Supplying the bloodstream with any more amount of zinc can lead to the serious outcomes:

  • They can irritate the stomach and mouth: If taken incorrectly or by individuals sensitive to the substance, it can potentially cause stomach discomfort and other side effects such as upset stomach, diarrhea, nausea and vomiting, according to Livestrong.
  • Zinc supplementation can lower copper levels in the body because zinc and copper compete for absorption in the stomach, and zinc tends to be absorbed more rapidly, leading to reduced copper absorption and potential copper deficiency, according to Healthline.
  • Zinc nasal spray can cause loss of smell. A recent study cautioned against zinc-based homeopathic remedies for the common cold. It warned that they can lead to a loss of sense of smell.
