Estrogen also reduces the risk of colon cancer, diabetes, and Alzheimer's disease. In combination with natural progesterone it may reduce the risk of breast cancer. Many of us don't realize that the hormones we take are usually synthetic. By taking natural hormones, most of these side effects can be avoided. Besides, many of the good effects of estrogen are actually blocked by synthetic progestins like Provera.
Natural hormones tend to be made from soy and yam products.
Some women may need to avoid estrogens. Those with active liver, gall bladder disease, cervical cancer or pre- cancerous lesions, and deep vein thrombosis probably need to avoid estrogens. The more and stronger the risk factors, the more warranted is caution about estrogen. Remember, progesterone lessens risk, natural hormones lessens risk, and estriol is actually protective. Nonetheless, a program of progesterone enhancement, diet, and healthy lifestyle outlined below is often sufficient for those with low risk of Alzheimer's, heart disease and osteoporosis.
