Life-changing! If you are suffering from menopausal symptoms or just don't feel as vibrant as you used to, do yourself a favor and visit Dr. Brannon. I have had compliments about my skin, weight loss, and general attitude shift after only 6 months of treatment. The outcome is priceless.

Professional, knowledgeable, enthusiastic, responsive ... those are the words that come to mind when I think of Dr. Brannon and Optimal Bio. They provide answers and real hope for people in today's society. No longer do you have to "struggle" and "settle" for changes in your body's hormone levels. There is hope! You will find it at Optimal Bio!

I am so glad and very grateful that Dr. Brannon introduced me to bioidentical hormone replacement therapy. They have improved my energy, PMS symptoms, cognition, and overall well being. He provides a wealth of knowledge through his website to help empower his patients to live optimal lives!! Dr. Brannon provides solutions that work to improve your health and overall well being. He is a very compassionate and caring physician. His office staff is phenomenal and very professional.

What Makes Optimal Bio Different?

We don’t just balance hormones, we balance you.

Whole Body Approach

At Optimal Bio, we don’t just balance your hormones, we balance your whole body. We take an integrative approach to your overall physical and mental health by identifying your optimal hormone and supplement dosage, along with a structured wellness plan. We listen to your health concerns and review your comprehensive medical history to develop a holistic plan tailored to your specific needs.

Optimal Bio Analysis

At Optimal Bio, it's not just about test results on a page, it's about how you feel. Our in-depth Optimal Bio Analysis uses an algorithm based on your specific lab results, health history and symptoms, including your gender, physique, and overall activity, to develop your individual hormone therapy plan. You get the results you are looking for by returning your body to the hormone levels it was initially designed to maintain, reaching your optimal hormone balance.

Naturally Better

At Optimal Bio, we provide an all-natural and bioidentical alternative to the traditional, synthetic hormone therapy. The hormone pellet placements we use are 99.5% natural and plant-derived. Because their structure is identical to the hormones made by your body, they are easily metabolized with no harsh side effects.
