I can't get real good answer.. but I have estradiol.... doctor said to take it, but didnt say how... so I started taking as a pill... but read some where, unsure where, that people take it by placing it under their tongue... so I have done this a couple times, and when I do .. take it this way, I get like a little "rush" of emotions and excitement like feelings, goose bumps, etc... like minutes afterwards... where as just taking it as a pill, I don't.... so I am at odds trying to figure out which way is best... if asking me, would be taking under the tongue... but I am not sure if that should be good or not? grrr -_-
