I think that's a common maca side effect and has nothing to do with your blood pressure. My blood pressure is always low but I also had palpitations with maca and extremely vivid nightmares. That was only the first week though and I stopped taking it after 4 PM. I'd take one in the morning and another at 3 or 4 but not after that, I already have a super active mind and always have trouble sleeping because I'm over analyze every word and move people made that day. When I do sleep i always have nightmares about the things I've been thinking about. Maca at night was making it worse.
