Elderberry

A potent dark purple berry highly concentrated in anthocyanins, renowned for supporting immune function and combating cold symptoms.

Clinical Profile

European Elderberry (Sambucus nigra) is a powerful immune-boosting botanical. Packed with antioxidants, particularly anthocyanins, it helps the body defend against oxidative stress. It has become a staple in winter wellness supplements, daily immune defenses, and gummy vitamins.

Clinical Summary

Strong clinical evidence shows that elderberry extract can significantly reduce the duration and severity of upper respiratory tract infections and influenza symptoms when taken within the first 48 hours of onset.

Dosage Guidelines

150-300mg of standardized extract daily for maintenance; up to 1200mg divided throughout the day during acute illness.

Safety & Side Effects

Extremely well tolerated. Note that raw or unripe berries are toxic and cause severe stomach upset, but commercial cooked extracts are perfectly safe.

Known Interactions

May theoretically interact with immunosuppressants due to its immune-stimulating properties.
