What are good supplements to increase energy without increasing blood pressure? My doctor told me that Ginko Biloba is a good supplement. Are there any others that work well without increasing blood pressure, especially for seasonal affective disorder?

If your doctor told you I would honestly have to say that is correct statement to give to a patient.
B-Vitamins are good for energy and don’t increase BP.
I would trust your doctor, however if you want a non-medical remedy, you should try using something with Ginsing
In addition to Ginkoba, try Ginsana. I take both; I also drink green tea…it has ginsana in it, also lots of antioxidants. You can get decaffeinated green tea, if caffeine is an issue.
The best tea I’ve ever tasted is “TradeWinds.”
So you’re SAD too. Awful, isn’t it. Both daughters we lost died in the fall/winter season, so I know how you’re feeling.
