Thorne’s Broccoli Seed Extract is not just another antioxidant supplement, it is a powerful, long-lasting defence system for your cells. Traditional antioxidants like vitamin C, vitamin E, and beta carotene offer short-lived protection, typically neutralising free radicals for only a few hours. But this supplement takes a different approach. Once ingested, it undergoes a unique breakdown process in the gut, releasing sulforaphane. This potent compound doesn't just act directly; it triggers your body’s own detoxification and antioxidant enzymes, providing cellular protection that lasts for several days. This extended protection is crucial, especially in today’s world where our bodies are constantly exposed to oxidative stress from pollution, processed foods, and daily stressors. Thorne’s Broccoli Seed Extract doesn’t just provide a quick fix, it equips your body with the tools to continually defend itself against ongoing threats, helping to maintain cellular health over time.

The science behind sulforaphane is robust, with more than 500 journal articles published in the past two decades. This wealth of research highlights its role in promoting not only antioxidant defence but also in supporting detoxification pathways, reducing inflammation, and even influencing gene expression related to health and disease. By incorporating sulforaphane into Thorne’s Broccoli Seed Extract, you’re not just getting a supplement – you’re receiving a research-backed, comprehensive approach to long-term health and vitality.
