About





            

                
Vitamin E is the primary lipid-soluble antioxidant in LDL particles and cell membranes. Despite strong mechanistic rationale, large RCTs have been disappointing. The HOPE trial (9,541 participants) found no cardiovascular benefit at 400 IU/day, and a 2005 meta-analysis found high-dose vitamin E (>=400 IU/day) was associated with increased all-cause mortality. Current AHA guidelines do not recommend vitamin E supplementation.

            

        

        

        
        
        

            

  
How It Works





            

                
Primary lipid-soluble antioxidant in LDL particles and cell membranes; inhibits LDL oxidation — a key early step in atherogenesis; modulates inflammatory gene expression via NF-kB inhibition; inhibits platelet adhesion and smooth muscle cell proliferation.
