Brief Summary

A natural form of vitamin E called tocotrienol (TCT), found in many common foods such as barley, decreases stroke size in animal models. Vitamin E has blood-thinning properties and lowers cholesterol, which make it a potential therapy for stroke prevention, though these effects are less well characterized for TCT. We plan to conduct two trials (I \& IIA) to determine the effects of orally supplemented TCT on platelet function and cholesterol.
