Dr. David Kahana

Gastroenterology

Dr. David Kahana is board certified in Pediatrics and Gastroenterology through the American Board of Pediatrics (ABP), as well as Medical Nutrition through the National Board of Physician Nutrition Specialists.

Hi, I am Dr. David Kahana and I’m a board certified gastroenterologist. I trained at UCLA and in Chicago, Minnesota, and Israel and opened the Center for Digestive Health & Nutritional Excellence in Torrance, CA, in 2011. My medical career was inspired by my older brother who became very sick as a child with ulcerative colitis. Wanting to understand this gastrointestinal disease fueled my pursuits through the digestive field with the hopes of finding natural solutions.

As a certified Physician Nutrition Specialist, I have a strong appreciation for and understanding of the benefit that nutritional therapy provides for gastrointestinal conditions. I always felt boxed in by Western medicine, which seems more interested in treating disease rather than the person as a whole. The desire to step out of this box to provide alternative nutrition-based healing brought me to partner with 1MD and their esteemed physician formulators. Together, we are working to transform traditional approaches to health.  

My close work with dieticians and nutritionists  has been fundamental to the research we conduct. Understanding the role that nutrition plays in healing and improving overall health, guides our search across the globe for natural ingredients and herbal extracts. The goal is to create effective and lasting solutions for gastrointestinal issues, and to enable the body to take care of itself.

1MD wanted to go beyond what other supplements do, to create superior formulas that are free from chemicals and unpleasant side effects. We collected superfoods and set out to formulate products that would improve overall health and change lives for the better. Using the latest technologies, we arrived at the most powerful solutions to promote optimal digestive health with no artificial ingredients and no compromises. 

Together with 1MD, we developed a collection of supplements to support and improve digestive function, each with a combination of natural and clinically-proven ingredients. For example, digestive enzymes can support digestive health and reduce harmful effects of poorly digested food. Other formulas eliminate pathogens, which allows the gut to heal and strengthen its barrier. Most importantly, we understand the essential need for microbial balance in the gut for immune health, and our broad-spectrum Complete Probiotics Platinum™ formula is designed to encourage this balance. 

Our proprietary blend of probiotics and prebiotics are featured in several digestive products, each developed to promote healthy gut function and boost immunity. 1MD understands that women have a unique microbial community and BiomeMD®️ for Women contains 62 billion CFUs of probiotics and 4 potent prebiotics to support digestive health and also includes specific probiotics strains for targeted feminine care.

The benefits of the 1MD digestive care line does not stop there. We provide beneficial and healing supplements to support organs like the liver, which is essential to the digestive process. Our 2020 Nexty Award-nominated LiverMD® contains EVNolMax® , a super-charged vitamin E to help optimize liver function for better energy, metabolism, and overall health. We also went beyond traditional milk thistle supplements, including Siliphos® Bioavailable silybin, which has been proven to be 10 times more absorbable than generic milk thistle extract. 

The natural solutions 1MD provides combine science with a holistic approach to health. We want to deliver whole body health and more effective results. The natural, healing ingredients in our formulas along with better nutrition, fitness, and enhanced mental well-being can give you the lasting overall health effects you seek. 

We broke through the noise and created the new standard with real solutions that address America’s gravest health concerns. 1MD formulates potent and effective nutritional supplements by sourcing the highest quality, clinically validated, natural ingredients backed by science, so you will feel the difference. Seeing people live healthier and happier lives is the most rewarding part of my work.

Every day, I stay atop the latest gastrointestinal, digestive, and nutritional research. Combined with my clinical training, I use science to deliver therapies that will improve the lives of millions, so there is no more needless suffering with digestive issues. The 1MD digestive suite collection of superior natural treatments is everything your gut needs. 

Warmly,

Dr. David Kahana
