Elderberry
Traditionally used to support immune response and ease cold or flu symptom duration
Forms
Syrups, gummies, capsules, lozenges; standardised Sambucus nigra extract
Advantages
Some evidence for modestly reducing cold and flu symptom duration when started early
Disadvantages
Evidence base is smaller than more established immune nutrients; quality varies between products
Side effects
Mild GI upset; raw or unripe elderberry (not the prepared supplement form) is toxic
Interactions
May theoretically overstimulate the immune system — caution in autoimmune conditions or with immunosuppressant medications
At-risk groups
People wanting extra immune support during cold and flu season; caution in autoimmune disease
Cautions
Choose reputable brands using properly processed extract; discontinue if used for more than a few days without symptom improvement
