Crucera-SGS is advanced antioxidant formula made from broccoli seeds for cell support and liver detoxification.* 
Sulforaphane glucosinolate (SGS) is a natural substance extracted from the seeds and sprouts of select broccoli varietals. It is an indirect antioxidant that provides long-lasting cell support.* Typical antioxidants, such as vitamin C, vitamin E, and beta carotene, work ""directly"" to neutralize free radicals and are usually effective for only approximately three hours after ingestion.* 
When Thorne's Crucera-SGS is ingested and begins to break down in the gut, it releases sulforaphane, thereby activating the body's natural detoxification and antioxidant enzymes and providing cell support for several days.* Each capsule of Thorne's Crucera-SGS provides the SGS equivalent of eating two pounds of cooked broccoli.*
