Elderberry and immune
Elderberry is a supporting nutrient for immune support. Elderberry (Sambucus nigra) is rich in anthocyanins and has been studied for upper respiratory tract infections. A 2019 meta-analysis (4 RCTs, 180 participants) found elderberry supplementation significantly reduced duration and severity of upper respiratory symptoms, particularly when taken within 24 hours of symptom onset. A 2016 RCT (312 air travelers) found reduced cold duration and severity.
Effective dosing
Most evidence supports 300–600 mg of elderberry daily. Clinical trials use 300–600 mg/day of standardized extract. Sambucol studies use equivalent to ~3.8 g raw elderberry juice. Syrup doses vary widely. Products below this range may not deliver meaningful results.
