In my notes I have:
Keep SHBG in check with Chrysin, Quercetin (inhibit aromatase), Nettle root, Fishoil, protein
Combining nettle root with Pygeum results in a stronger synergistic inhibition of SHBG binding.
Nettle prevents SHBG binding to cell membrane and therefore reduces hormone related cancers
Regarding low free-T and high SHBG you could try:
DHEA 15-20mg daily
VitD3 5-10k iU
stinging nettle Root (mixed results)
Eat High protein, Low glycemic carbs
I can't validate any of this as i have been focused on other things recently but it is something I will be looking at for myself soon.
