Each cell in our body contains the central metabolic machinery which converts the carbohydrates and fats in our food to energy and other useful compounds needed to function healthily. As we age or when our cells become stressed, our metabolic machinery starts to work less well and begins to make what are known as reactive oxygen species (ROS). While a healthy cell needs a small amount of ROS, too much can be damaging. By having regular doses of glucoraphanin, we can keep our ROS within safe limits, which helps our metabolism to function normally. One consequence of keeping ROS in balance is that we can burn up fat effectively, rather than storing it in our bodies.
