I learned about the importance of natural hormone cream by reading "What Your Doctor May Not Tell You About Menopause" by Dr. John R. Lee. I had a saliva test and was very low in progesterone. My doctor worked with my compounding pharmacist to prescribe a hormone cream that is uniquely designed for me. I feel so much better, it gave me a new lease on life, with more energy, better sleep, and better memory and brain function. I am having a much better result with the compounded cream.
