To date, there is no research indicating whether or not the risks associated with oral CEE are also linked to compounded oral BiEst (estriol + estradiol) and TriEst (estriol + estrone + estradiol.
None of the synthetics, animal source or bio-identical hormones are “natural” – all are highly processed chemicals. Despite what proponents of “natural” hormone enthusiasts tell you, I’ve found that synthetic, animal and bio-identical hormones share most of the same benefits and side effects. Botanical estrogens may be slower to work and not as strong, but are often effective and safer.

When discussing estrogen it is important to note that “estrogen” is an umbrella term for many different estrogens including estriol, estrone, and estradiol. All three of these estrogens are produced in the body and have physiological effects. In the past, estriol was believed to have little physiological significance due to its weak estrogenic activity when compared with estrone and estradiol. Nonetheless, research suggests that estriol’s weakness may confer certain beneficial effects in contrast with more potent estrogens.
