Dr. Devaki Lindsey Berkson is a thought leader in functional medicine, with an emphasis on hormones, nutrition, digestion, and intimacy. She’s a doc who walks her talk.

For years she was ill with cancers and serious health issues. While writing one of the first breakthrough books on endocrine disruption (Hormone Deception, McGraw-Hill), she discovered she was a victim of the very phenomena she was explaining to the public. Once she knew why and what was wrong, she could then formulate her own medication and nutrients to stop the tumor madness successfully. Thus, Berkson not only connects-the-dots of science, but also offers hope. Once you find the root cause of the illness, an informed practitioner can usually create natural effective answers.

Berkson got invited to be a distinguished hormone scholar at a world-renowned estrogen think tank at Tulane University (Center for Bioenvironmental Research) because she wrote one of the first breakthrough books on endocrine disruption (Hormone Deception McGraw-Hill 2000).

Dr. Berkson wrote the first gut-nutrition-spirituality book, Healthy Digestion the Natural Way, a best seller (Wiley & Sons 2002)

Dr. Berkson has taught re-licensing seminars to professionals (MDs, pharmacists, chiropractors, NDs, acupuncturists, nutritionists) and formulated the first female nutraceutical line for physicians in the U.S. and now Biotic’s first female line (Receptor Detox, Hormone Balance & Protect).

Berkson is often a keynote at prestigious medical and pharmaceutical symposium.

Berkson is credited with the in-depth knowledge of Estrogen Vindication and has an eBook on Hormones for Breast Cancer Survivors at DrLindseyBerkson.com.

Berkson and Dr. J.V. Wright hold a patent on bioidentical hormones and she holds another collaborative patent on a drug for dialysis and diabetic patients. She has collaborated and published research on dialysis and nutrition with The University of Texas Medical School at Houston.

Berkson hosted the Dr. Berkson’s Best Health Radio Show. She is a fellow of the prestigious research institute, the Health Science Collegium.

Berkson consults with people and physicians internationally and specializes in complex cases. She pioneered the concept of “green pregnancies” and the “unappreciated role of hormones and the gut”.
