Sulforaphane is a powerful antioxidant, in fact the strongest known natural inducer of the bodies key antioxidant enzymes, Glutathione and Quinone oxidoreductase.

Oxidative stress is present in many chronic illnesses of the lung including Asthma & COPD (1).

Reduced levels of Glutathione (GSH) have been found in people with Asthma & COPD. The illnesses are characterised by an imbalance in Reactive Oxygen Species (ROS) and available antioxidant defences.

Sulforaphane, the active ingredient in FOUR HEALTH Green has been shown to support the production of the bodies key antioxidants:

Glutathione (GSH),

Quinone oxidoreductase (NADPH)

In fact it’s nature’s most potent known inducer of these key antioxidant enzymes2.

Scientific studies show that consuming broccoli sprout extract results in increased presence of Phase II Liver detox enzymes in the human upper airway (2), which shows promise in reducing oxidative stress in the lung. Human clinical trials showed a positive response to Sulforaphane in Asthmatics significantly improving FEV1 (3).

Both human clinical trials (COPD, Asthma) had dosage of 19mg/day of Sulforaphane, the same present in FOUR HEALTH Green.
