Did you try natural remedies?
I’ve tried rosemary oil and I also tried spearmint tea, which I still drink from time to time. It’s supposed to help raise SHBG. My SHBG is typically already high to begin with, but I notice when I drink it daily my SHBG goes up more than my usual baseline and my free T comes down more as the SHBG binds it. My free T isn’t high, but sometimes it’s in the middle of the range and I figure I’m sensitive to it so it’s better to keep it as low as possible within the healthy lab range.
