my first reaction to this query is WHY YOU STARTED TAKING VITAMIN E? American heart association repeatedly says, VITAMIN E supplementation does not improve cardiovascular health and should be taken only in presence of proven clinical deficiency. Anecdotal reports are available which support both rise and fall in BP with vitamin E supplementation. i would rather ask you to look for other factors like BP instrument, persons involved in checking, number of such abnormal readings, dietary/weather changes and other stress
factors present at time of higher readings. these are all confounding factors.
i would repeat please do not take vitamin E unless prescribed by a physician for proven clinical indication.
please feel free to discuss further.
