Has the calcium actually helped? Originally you said it may have, but since your BP is still a little highish, maybe that wasn't the cause? But testing for several weeks is probably a good idea regardless.
There are some other BP supplements you can try, if you haven't already. Meganaturals makes a grapeseed extract with some BP lowering studies behind it. Pycnogenol is another alternative, but expensive.
It seems like *something* is helping a bit, hard to say what since I made several changes at once. Things I'm taking showed improvement at the end of 4-8 *weeks* in the research. So really I should be patient!
