The Active Ingredient Is: Sulforaphane

Sulforaphane is basically a bioactive compound from cruciferous vegetables and is recognised for its role in cellular defence and antioxidant protection.

This form comes from concentrated cruciferous extracts, which supply sulforaphane alongside related phytochemicals to support the body’s natural antioxidant and detoxification processes.

What Does Sulforaphane Do?

Sulforaphane plays a part in the body’s defence by activating detoxification pathways and supporting cellular protection against oxidative stress, in line with EFSA and NHS-style guidance. Studies suggest it can upregulate antioxidant enzymes involved in cellular resilience.

Dr. Yanaka from a Japanese university found that sulforaphane helps bolster cellular defence mechanisms through NRF2 activation, contributing to normal physiological protection backed by reputable research.
