Eldermune

Also known as: Elderberry, Black elder, European elder, Elder, Sambucus, Sambucus nigra

Overview

Elderberry, derived from the *Sambucus nigra* shrub, is found throughout Europe and North America and has been traditionally used for its immune-boosting and respiratory health benefits. The flowers and berries are rich in anthocyanins, flavonoids, and phenolic acids, which contribute to its antioxidant properties and potential antiviral effects. Elderberry is often used in supplements like Eldermune to address colds and influenza. While various studies indicate its effectiveness in reducing the duration and severity of flu symptoms, more rigorous clinical research is necessary, as many findings are based on in vitro and animal studies rather than extensive human trials.

Benefits

Elderberry provides several evidence-backed advantages, primarily significant antiviral and immune-supporting effects. Studies indicate that it can reduce both the duration and severity of influenza and upper respiratory symptoms, particularly beneficial for healthy individuals and those affected by viral respiratory illnesses. A systematic review confirmed a large mean effect size for alleviating upper respiratory symptoms, supporting elderberry's therapeutic potential. Additionally, its antioxidant capability aligns with other berries, potentially mitigating oxidative stress. Despite these promising benefits, more robust clinical trials are required for definitive conclusions.

How it works

Elderberry exhibits antiviral properties through its ability to inhibit viral replication and bolster immune response. The compounds in elderberry, particularly anthocyanins and flavonoids, interact with viral proteins to hinder infection. Furthermore, elderberry may modulate cytokine production, essential for a robust immune response. This interaction with immune pathways supports its suspected efficacy in managing respiratory infections, although bioavailability evidence is currently limited, with existing studies indicating good absorption rates for anthocyanins.

Side effects

Elderberry is generally safe when consumed as recommended, with few side effects, the most common being mild gastrointestinal discomfort. Allergic reactions may occasionally occur but are rare. Importantly, raw or unripe elderberries are toxic and must be avoided. Elderberry supplementation may also interact with diabetes medications by affecting insulin secretion, necessitating caution for individuals with blood sugar management concerns. Pregnant or breastfeeding individuals should refrain from using elderberry unless under a healthcare provider's advice. Continued monitoring for potential adverse effects is advised as additional data emerges.

Dosage

The typical dosage for elderberry supplements ranges from 600 mg to 900 mg per day for immune support, although individual responses can vary. While no definitive minimum effective dosage is established, a daily intake of 500 mg to 1,000 mg of anthocyanins is recommended. There is no established upper limit, but excessive intake may cause gastrointestinal upset. It is beneficial to start supplementation at the onset of cold or flu symptoms for optimal results. Capsules and syrups are common formulations, and food may enhance the absorption of elderberry compounds.
