Kansas City Bioidentical Hormonal Replacement Provider

Bioidentical hormonal replacement therapy (HRT) uses naturally derived hormones that match the same molecular structure as hormones produced in the body. They offer an alternative to synthetic hormones that are mass-manufactured and come through health care providers and pharmacies. Bioidentical hormones can be individualized, meaning we draw your blood to determine which hormones you need more of and which ones you don’t. We then prescribe therapies to address your particular needs. This tailored approach leads to many patients preferring the bioidentical route over the standard “one-size-fits-all” synthetic hormonal replacement therapy. Oz Preventive Medicine treats many patients seeking natural hormonal replacement therapy. Some of the most common reasons we see patients include:

What a difference you have made in my life

Frankly, without Dr. Lang's acumen at replacing my hormone levels to an appropriate level, I don't think I could have continued to work in my field of expertise. In my mid 40's I started experiencing fatigue, brain fog, lack of confidence, timidity, and lack of focus - not to mention irritability, anger and a lack of libido. Dr. Lang helped me discover that my testosterone levels were below even the "normal lab range". He explained to me the theory behind replacement therapy and convinced me that I could return to my former self - with a little effort on my part. The BHRT was just part of the anti-aging protocol; the more I was able to adhere to the other components, the more benefit I would receive. After just three weeks of testosterone therapy, modifying my diet, and moderate exercise, I was more than elated with the results. My wife asked me where I had been for all those years. All I could say was I just didn't know. Well, now I do, and I can tell you I will never go back to that angry, tired, old man.
