Elderberry

Elderberry Benefits: Immune Support & Antioxidant Protection

What it is

Elderberry is a dark purple fruit produced by the Sambucus nigra plant, which grows throughout Europe and parts of North America. The berries have a long history of use in traditional medicine and are rich in anthocyanins, flavonoids responsible for their deep color and antioxidant properties.

In modern supplements, elderberry extracts are commonly used to support immune health, particularly during seasonal illness.

How it works in the body

Anthocyanins and other polyphenols found in elderberry have antioxidant and anti-inflammatory properties that may support immune system function. Laboratory research suggests that elderberry extracts may influence immune signaling pathways and stimulate the production of certain cytokines involved in immune responses [1].

Some experimental research has also suggested that elderberry compounds may inhibit viral entry into host cells by interfering with viral surface proteins, although more research is needed to fully understand this mechanism in humans [2].

Clinical studies investigating elderberry supplementation have reported reductions in the duration and severity of certain respiratory symptoms in individuals with viral infections, although findings vary depending on study design [3].
