What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

Selenium and Vitamin E provide antioxidant support, while riboflavin acts as a cofactor for cellular energy production. Glucoraphanin is associated with phase II detoxification pathways. Research evidence for these specific combined effects is limited, though individual components are well-studied.
