About this clinic

National Integrated Health Associates (NIHA), a functional and integrative medicine clinic in Washington, DC, offers acupuncture, IV therapy, and ketamine therapy alongside comprehensive functional-medicine assessment. The practice emphasizes a whole-person, evidence-based approach to chronic conditions including autoimmune disease, cardiovascular health, and post-viral syndromes. Practitioners conduct detailed workups to identify underlying drivers of illness rather than treating symptoms in isolation. IV nutrient therapy and ketamine protocols are available for patients whose conditions warrant these modalities. The clinic also provides biological dentistry, including mercury-amalgam removal and biocompatible restorative care, positioning

If you want results fast visit Dr. Coy. We go to him for more than 10 years and would not switch. In 30 min session he "fixed" my son from barely being able to stand and walk to playing soccer game in the evening. And I am not exaggerating. We are grateful for finding such a great chiropractor. Thank you Dr. Coy.

Dr Wu is a wonderful, calm, reassuring, highly competent acupuncturist! He’s helping me a great deal. In Dentistry, you won’t find a more compassionate & thoughtful one than Dr. Davoudian. I especially like that he takes the most natural approach first and doesn’t immediately jump into expensive procedures unnecessarily. I have a lot of anxiety about dental procedures & he works with me to ease that as well as get the necessary work accomplished.

Dr Coy is amazing. Knowledgeable about more than just chiropractic techniques, he has different modalities. He knows the body works and how it works with the mind and the nervous system. He takes his time and on top of that is a very friendly good human
