My dentist, Dr. Robin Levy, recommended this toothpaste. I absolutely love it! I’ve already bought another tube for a loved one. I have also told everyone that asks about my recent dental work to purchase some and start using it now! Their teeth and gums will thank them!!

Life changing!!!
Format: Paperback
This book and Ray’s work have completely changed my life! After years of debilitating menstrual and premenstrual pain, high estrogen & testosterone/low progesterone, GI issues, migraines, and all other physical indicators of endometriosis, I have found relief and balanced my hormones in just a few months. I cannot recommend this book enough
