Active Compound Broccoli seed extract standardized for glucoraphanin (sulforaphane glucosinolate), the precursor to sulforaphane.

Benefits

Detoxification support

Sulforaphane from glucoraphanin switches on the body's Nrf2 pathway, which boosts detoxification enzymes that clear toxins and free radicals.

Supported by Trial 1

Antioxidant defense

By activating Nrf2, sulforaphane raises the body's own antioxidant defenses, offering long-lasting cellular protection.

Supported by Trial 1

Liver support

In a human study, sulforaphane-rich broccoli sprout extract improved markers of liver function.

Supported by Trial 1

Mechanism of action

1

Glucoraphanin to sulforaphane conversion

The enzyme myrosinase (from the plant or gut bacteria) converts glucoraphanin into active sulforaphane in the body.

2

Nrf2 activation

Sulforaphane activates the Nrf2 transcription factor, upregulating a broad network of antioxidant and detoxification enzymes.
