Elderberries and Flu Season: Understanding the Science and Real-World Experiences

As we navigate through flu season, many of us are searching for natural ways to support our health. Elderberries have become a topic of interest in this quest. But the burning question remains: can elderberries prevent the flu?

What does the Science Say?

We’ve hired Dr. Catherine Stein from Case Western Reserve University to compile full-article literature on elderberries, the bioactive component of elderberry and more. See below.

The Power of Elderberries: A Closer Look at Their Compounds

Elderberries are a rich source of bioactive compounds, including flavonoids, proanthocyanidins, and phenolic acids. These compounds are known for their antioxidant properties, playing a pivotal role in supporting the body’s defense system and helping to manage the oxidative stress that can lead to various health issues.

Flavonoids: Antioxidants and Immune Modulators

Flavonoids, a diverse group of phytonutrients found in many fruits and vegetables, are celebrated for their antioxidant properties. But what does this mean for our immune system, particularly in relation to flu-like symptoms?

  1. Antioxidant Power: Flavonoids help neutralize free radicals in our bodies, which can otherwise contribute to oxidative stress, a factor in many health conditions.
  2. Immune Response Modulation: Research indicates that flavonoids may influence the immune response. A study on PubMed.gov reveals how certain flavonoids can support the body’s natural immune defenses.
  3. Respiratory Health: Specific flavonoids have been linked to supporting respiratory health, an essential aspect during flu season.

Studies, such as those found on PubMed.gov, have highlighted the role of flavonoids in modulating the immune response, which is crucial during flu season. They are also linked to supporting respiratory health, a key factor in managing flu-like symptoms.

The primary flavonols found in elderberries include:

  1. Quercetin (a zinc ionophore)
  2. Kaempferol
  3. Isorhamnetin

Proanthocyanidins: Supporting Immune Function

Proanthocyanidins, a type of flavonoid, are found in high concentrations in elderberries, primarily in the form of anthocyanins, which are responsible for the berry’s characteristic dark purple color. The specific types and their concentrations can vary based on factors like the variety of elderberry, growing conditions, and processing methods. However, in general, elderberries are known for their high anthocyanin content.

These compounds have their unique benefits:

  1. Supporting Immune Function: They may play a role in supporting the body’s immune function, as detailed in a study found at Trisha’s Elderberries.
  2. Antimicrobial Properties: Some research suggests that proanthocyanidins have antimicrobial properties, which might be beneficial in the context of viral infections.

Phenolic Acids: Antioxidant and Anti-inflammatory

Phenolic acids are another group of compounds in elderberries known for their health-promoting properties.

  1. Antioxidant and Anti-inflammatory Effects: These acids have strong antioxidant and potential anti-inflammatory effects, which are vital in the body’s response to pathogens.
  2. Supporting the Immune System: As highlighted in an article on PubMed.gov, phenolic acids can play a role in immune health, crucial for managing flu-like symptoms.

Elderberries contain several phenolic acids, including:

  1. Caffeic acid
  2. Chlorogenic acid
  3. Ferulic acid
  4. Gallic acid

Elderberries: More Than Just Their Components

While understanding these compounds is crucial, it’s important to remember that the benefits of elderberries come from the synergistic effects of all their components. Elderberries, as a whole, have been traditionally used for their health-supporting properties, particularly in relation to immune health.

Elderberries, rich in flavonoids, proanthocyanidins, and phenolic acids, offer a symphony of compounds that can support our health in various ways, especially during flu season. While these compounds are not a cure or a direct preventative measure for the flu, their role in supporting immune health and overall well-being cannot be overlooked. As always, consult with a healthcare professional for personalized advice.
