Cistanche tubulosa extract is a natural supplement sourced from the cistanche plant, featuring echinacosides as its main active components. This extract helps support typical immune function and overall wellbeing via its bioactive compounds.

This formula is standardised to echinacosides, delivering a defined level of the active constituent inside a vegetarian capsule format.

What Does Cistanche Tubulosa Extract Do?

The active extract helps support immune system activity and balance as part of healthy ageing. It helps maintain typical immune function and general cellular health, in line with evidence on immune support and related metabolic processes.

Scientific research suggests echinacosides may support natural killer cell activity and T-cell balance, contributing to immune system maintenance, (which isn’t about disease outcomes).

This supplement isn't intended to diagnose, treat or prevent any disease.
