What Happens to Your Immunity When You Take Elderberry and Zinc Together

Key Takeaways

  • Elderberry is rich in antioxidants that support immune function and help fight illness.
  • Zinc plays a crucial role in building a strong immune system.
  • Taking elderberry and zinc together may help prevent or shorten colds and flu more than using either alone. However, research into the combined effects of zinc and elderberry is lacking.

Taking elderberry and zinc together provides more comprehensive immune support than using either alone. Zinc supports the optimal function of your immune system, while elderberry offers antioxidants that help your body fight infections more effectively.

How Elderberry Affects Immunity

Elderberry comes from the Sambucus tree. People have used its fruit for centuries to manage colds and flu. The berries contain vitamin C and antioxidants, especially anthocyanins and flavonoids, that support your immune system and protect your cells from unstable molecules that can cause cell damage, called free radicals.

These antioxidants may also help your body increase its production of immune molecules called cytokines, which play a role in your early immune response. This effect can help your immune system react more quickly when you come into contact with germs.

Some preliminary studies suggest that elderberry may help prevent infections, such as the common cold and flu, by blocking viruses from entering cells and supporting immune cells that fight infections. However, results from clinical trials are conflicting and suggest that elderberry may not reduce the risk of developing the common cold.

Taking elderberry at the first sign of illness may help your body respond and heal more quickly. Research shows elderberry can shorten the duration of a cold or flu and reduce symptom severity.

How Zinc Affects Immunity

Zinc is an essential mineral your immune system needs to work correctly. It helps the body produce and activate white blood cells, which identify and combat viruses that cause infections. Zinc also supports the skin and the lining of your nose, mouth, and gut—your body’s first barriers against infection.

Because your body can’t make zinc on its own, you need to get it through food or supplements. When you don’t get enough zinc, your immune response weakens, and you become more susceptible to infections and may take longer to recover from illness.

Research shows zinc can help your immune system respond to infections. Studies suggest that zinc may shorten the duration of a cold and reduce symptoms if taken soon after they start. Zinc works by preventing viruses from multiplying and supporting immune cells that clear infection.

What Happens When You Take Elderberry and Zinc Together

Combining elderberry and zinc offers a more robust immune defense than either supplement separately. By acting through different immune pathways, they help strengthen your system’s ability to fight infections.

  • Elderberries’ antioxidants protect cells and support your body’s response to viruses.
  • Zinc supports immunity by helping your body create and activate infection-fighting white blood cells. It also maintains the protective lining of your mouth, nose, and throat, the first line of defense against germs.

When used together, elderberry and zinc may offer broader immune benefits than when either supplement is used alone. However, there is little scientific research into the combined effects of zinc and elderberry. Further research is needed.

How Much Should You Take?

Zinc and elderberry supplements are available in various forms. Zinc is commonly available in tablet, capsule, lozenge, liquid, and chewable forms. Elderberry is often sold as syrups, gummies, capsules, lozenges, and teas made from dried berries or extracts. The correct dose varies depending on the product and your individual needs.

  • Elderberry: Most studies use 300-600 milligrams (mg) of elderberry extract per day. For syrup, gummies, or capsules, follow the product label, as strengths vary.
  • Zinc: Most zinc supplement doses range between 15 and 30 mg per day. Do not exceed 40 mg per day from all sources, including food and supplements.

When Should You Take Elderberry and Zinc?

Many people take elderberry and zinc daily during cold and flu season to support their immune system. Others wait until early symptoms, like a scratchy throat or fatigue, before starting. If you take elderberry and zinc daily, you can take them together or separately throughout the day.

If you are taking other medications, consider taking zinc at a different time. Zinc can reduce the absorption of certain antibiotics, diuretics, and medicines used to treat rheumatoid arthritis. Take zinc at least 2 hours before or 4 to 6 hours after these medicines.

Safety and Side Effects

For most healthy adults, elderberry and zinc are generally safe when used at typical doses for short periods.

Possible side effects of elderberry may include:

  • Abdominal discomfort
  • Diarrhea
  • Nausea

Possible side effects of zinc may include:

  • A metallic taste in the mouth
  • Headache
  • Interference with copper absorption when taken at high doses or for long periods
  • Nausea
  • Reduced appetite
  • Upset stomach
