Flu Shot

Should You Get A Flu Shot Now?

The annual flu season runs from October through March in the Northern Hemisphere, though it could start earlier and last longer. In the Southern Hemisphere, it’s the opposite. So I look to Australia during July-August (our summer, and their winter) for clues of how bad our flu season might get, and how effective the flu ...Read More

How To Reach The 100-Year Life With NAD+ (Part II – Regulate CD38)

The “Age Wave” futurist Ken Dychtwald predicted is upon us.[1] It’s no secret. Baby boomers are getting older. But what do we call aging boomers? Older adults? That’s too generic. Not outdated terms like Gray Panthers or Senior Citizens popular in my mother’s “the greatest generation” era. To make it more taxing, boomers reject labels ...Read More

"The Physician’s Physician"

"There are few things Dr. Williams cannot do well. Besides dedicating his career to being a cutting-edge expert in the field of functional medicine, as well as serving as the physician’s physician; he is a gourmet chef, plays the piano, and is a prolific writer as demonstrated by the many books he has in publication. He speaks Spanish and is fascinated with indigenous cultures. But what impresses me the most is his natural ability to relate and transform a complex idea to an effortlessly consumed morsel of wisdom. It is no small wonder he is a great teacher because he is dedicated to being a student first!"

"I Feel like I'm Aging Backwards!"

"At the age of 60, I found that it was hard to ignore the noticeable signs of aging. Expensive skincare was no longer working, and I started looking into noninvasive anti-aging techniques. I was fortunate to be referred to Dr. Williams. First, he offered extensive blood work to see how well or poorly I was aging. Then he provided supplements and bio-identical hormones prescribed for my individual needs. I became a serious patient looking to stay young from the inside out. In the past eight years, Dr. Williams offered natural facial injections, PRP Therapy, and stem cell assisted fat transfer. My skin has naturally rejuvenated and is smoother and tighter. The compliments are endless! A real "Fountain of Youth.""

"I Look and Feel Terrific!"

"Integrity, cutting-edge, forward thinker, compassionate, intuitive knowledge, unwavering, global researcher, woman's medicine specialist, and healer. These words are just a few phrases describing Dr. James Williams. He has been my integrative medicine doctor for over thirty years. Over this time, he has treated me for something as small as an earache to a series of very challenging hormone issues. He practiced in San Diego, but now lives in Florida, and he is still my doctor. I wouldn't have it any other way. I am now 63 years old and know the value of choosing this man as my lifelong physician. I am healthy, vital, energetic, and look forward to the rest of my life. You deserve to be treated by someone of this caliber. JUST GO!"

"Practices What He Preaches"

"Dr. Williams is a walking and talking testament that he practices what he preaches. I am grateful for the privilege of our relationship and for allowing me to glean some of your knowledge."

Jade, CEO Pure Performance – San Diego, CA

"I Feel Privileged"

"I would like to express my appreciation to Dr. Williams for my recovery. My thyroid blood test results are now all within the normal range. I am sure that without his help and guidance, I would still be on thyroid medications. I feel so privileged to have met him."

"Never Saw Anything Like It"

"My cardiologist was very excited! After years of having congestive heart disease, he said I now had the heart and valves of a twenty-year-old. Never saw anything like it in an 80-year-old like me. Your treatments and supplements produced a new heart. All thanks to you, Dr. Williams."
