Concern over liver is due to findings with other forms of estrogen and how they affect liver, coagulation, etc. Their effects are far stronger than bio-identical estradiol, and personally, I have yet to read a study showing that bio-identical estradiol harms the liver.
When taken orally, half-life is usually 13-17 hours whereas when taken sublingually, it is MUCH less because it is quickly absorbed and then drops fast...so 2-3 hours.
Concerning serum levels measured a few hours after intake, orally and sublingual, you could have a look here:
transascity dot org/sublingual-versus-oral-estrogen/
According to their graph, blood levels were higher sublingually.
Well concerns are also concerning blood clotting factors. Sublingual there are supposed to be a bit less.
Some people take additinally a very low dose of i.e. aspirin when using oral.
Maybe its possible to use 4 small doses sublingual instead of 2 big ones.
Same for oral, some people say levels remain more steady than sublingual...
this would also concidence somewhat with what some people say about mood swings...
sublingual is supposed to be more efficient because less estro is converted or absorbed by the liver...
smaller doses spread throughout the day might help even out somewhat, both orally and sublingual.
talk it through with your doctor...
