Dr. Christiane Northrup, author of The Wisdom of Menopause, says there are two types of hormone replacement therapy that Robin could have chosen: bioidentical and synthetic. Dr. Northrup says there is some confusion as to how bioidentical hormones are created. "Bioidentical means it matches exactly the molecular structure of the hormone that your own body produces—it's a hormone from Mother Nature. So if you get the raw material from soybeans and yams, which they do, and then you convert it into something that matches your own body's hormone exactly, that is a bioidentical hormone," she says.
Dr. Northrup says synthetic hormones, the more conventional approach for treatment, differ from bioidenticals in their structure. "[Synthetic hormones are] made from horse urine and are natural for a horse. But they're synthetic for a human body. They are often added to a synthetic progestin, which doesn't match anything like your body's natural progesterone. It has completely different effects...Many women do well on these."
After doing extensive research, Robin decided that, for her, the best route was bioidentical hormone replacement therapy.
