Zinc is a mineral that is essential for the proper functioning of the human body. It plays a vital role in many different biological processes and is necessary for the proper functioning of the immune system. Zinc lozenges have gained popularity in recent years, particularly as a potential treatment for the common cold. In this article, we will explore the science behind zinc lozenges and determine whether or not they actually work.
What are Zinc Lozenges?
Zinc lozenges are small tablets that contain zinc. They are intended to be dissolved slowly in the mouth, allowing the zinc to come into contact with the throat and mouth. Zinc lozenges are available over-the-counter and are often marketed as a treatment for the common cold.
The Science Behind Zinc Lozenges
There have been numerous studies conducted on the use of zinc lozenges for the treatment of the common cold. While the results of these studies are somewhat mixed, there is some evidence to suggest that zinc lozenges can help to reduce the severity and duration of cold symptoms, particularly if they are taken within 24 hours of the onset of symptoms.
How Do Zinc Lozenges Work?
The exact mechanism by which zinc lozenges work is not entirely understood. It is believed that the zinc may help to inhibit the replication of cold viruses in the body, preventing them from spreading and causing further damage. Additionally, zinc may help to boost the immune system, allowing the body to fight off cold viruses more effectively.
What Does the Research Say?
While the research is somewhat mixed, there is some evidence to suggest that zinc lozenges can be an effective treatment for the common cold. For example, a review of 18 different studies found that zinc lozenges could help to reduce the duration of cold symptoms by an average of one to two days. Another study found that zinc lozenges could reduce the severity and duration of cold symptoms in children.
How to Take Zinc Lozenges
If you are interested in taking zinc lozenges for the treatment of the common cold, it is important to follow the instructions on the packaging carefully. In general, zinc lozenges should be taken within 24 hours of the onset of cold symptoms. They should be dissolved slowly in the mouth, rather than chewed or swallowed whole. It is also important to note that taking too much zinc can be harmful, so be sure to follow the recommended dosage on the packaging.
Side Effects of Zinc Lozenges
In general, zinc lozenges are safe and well-tolerated by most people. However, some people may experience side effects such as nausea, vomiting, or an upset stomach. Additionally, taking too much zinc can be harmful and can lead to symptoms such as dizziness, headache, and fatigue. If you experience any side effects while taking zinc lozenges, be sure to discontinue use and speak to your doctor.
Zinc-Rich Foods
In addition to taking zinc lozenges, it is also possible to increase your zinc intake through diet. Some foods that are rich in zinc include:
- Shellfish, such as oysters and crab
- Beef and pork
- Nuts, such as almonds and cashews
- Lentils and chickpeas
The Bottom Line
While the research on zinc lozenges is somewhat mixed, there is some evidence to suggest that they can be an effective treatment for the common cold. If you are interested in trying zinc lozenges, be sure to follow the instructions on the packaging carefully and speak to your doctor if you experience any side effects. Additionally, be sure to maintain a healthy diet that includes zinc-rich foods.
