Five health supplements that have shown some promise on COVID-19

While there's been much interest in using supplements to combat COVID-19, it's crucial to understand that there is no magic bullet and supplements should not be considered a treatment or prevention method.

However, some research suggests certain nutrients may support overall immune health, which could potentially play a role in your body's response to the virus. Here are 5 supplements that have shown some promise, but remember:

1. Vitamin D: Deficiency is linked to increased susceptibility to infections. Studies suggest adequate Vitamin D levels might be associated with milder COVID-19 cases. However, more research is needed. (1)
2. Vitamin C: An antioxidant supporting immune function. While high doses haven't proven effective in treating COVID-19, ensuring adequate intake through diet or moderate supplementation might be beneficial. (2)
3. Zinc: Crucial for immune response and cell division. Studies suggest zinc deficiency might be linked to severe COVID-19 cases. However, excessive intake can be harmful, so consult a doctor before supplementing. (3)
4. Elderberry: Early research indicates potential antiviral properties against influenza and respiratory infections. Some studies suggest elderberry might shorten COVID-19 symptom duration, but more research is needed. (4)
5. Melatonin: This hormone regulates sleep and has antioxidant and anti-inflammatory properties. Some studies suggest melatonin might improve symptoms and reduce the risk of severe COVID-19, but more research is needed. (5)

• Always consult your doctor before starting any new supplement,
