The Active Ingredient Is: Sulforaphane (Activated)

Sulforaphane is a potent bioactive compound that supports cellular defence and antioxidant defences in the body. This form is activated and stabilised for improved absorption from broccoli seed extract, providing bioavailable sulforaphane without the need for further processing.

This product uses broccoli seed extract as the source, with the sulforaphane activated to enhance availability for normal physiological function.

What Does Sulforaphane Do?

Sulforaphane is involved in activating the Nrf2 pathway, which upregulates antioxidant enzymes and supports cellular protection against oxidative stress. Research suggests this mechanism may contribute to cardiovascular and digestive health and healthy ageing, aligning with EFSA-style concepts of nutrient function.

Dr. Zhang of University has reported that sulforaphane activates the Nrf2 pathway, supporting cellular defence mechanisms in human cells.
