Here you can find detailed information on some of the products we've developed at North American. Many of the constituents must be understood in light of the blood type paradigm, so when and where appropriate, we'll be going over some of the basic mechanisms by which blood type has an effect on the product, and also, how the product effects each blood type. N.D. Although we very often hear of health problems such as female menopause being linked with low estrogen, there are many clinical and subclinical conditions that can benefit from inhibiting the excess production of estrogen and enhancing the production of testosterone.

Fibroids, a sign of excess proliferative capacity of the uterus, which may not be balanced with sufficient progesterone.
