Why Functional Medicine?

A Better Future For Our Patients & Community

Chronic diseases, such as cardiovascular diseases, diabetes, high blood pressure, and Alzheimer's disease, are the leading causes of death. As the number of patients with chronic diseases is increasing, we are beginning to understand the flaws of our current healthcare system. Together we can take the steps towards a brighter future and change how medicine is being practiced.

Understand The Root Cause

Mainstream medicine often uses drugs and surgery to treat symptoms and conditions. While many of these methods are important, it doesn't always effectively eliminate the causes of chronic diseases. In the Functional Medicine approach, we look at the root causes of conditions and dive deep into a patient's history, diet, and lifestyle and use advanced lab testing to better understand and address what initiated or is aggravating their chronic conditions, instead of masking it with drugs.

Safe, Effective, & Simple Tools To Change Healthcare

Functional Medicine was designed as a new approach to treating chronic diseases. We provide you the tools, training, and support to understand, test for, and treat the triggers of most chronic diseases. You will also learn about preventative medicine, nutritional and herbal medicine, stress management, use of technology in healthcare, and lifestyle adjustment to help your patients to change their lives.

Frequently asked questions

Functional Medicine is a new form of diagnosis and treatment that has been developing from the understanding that external factors can trigger a pathologic reaction by changing our inner biochemistry, such as the effect of flame retardants on the expression of our genes.

Disease, according to Functional Medicine, is the result of an interaction of our cells and organs with environmental factors, diet, emotional state, trauma, and lifestyle, rather than the result of genetics or old age.

Symptoms, according to Functional Medicine, rises from one or more biochemical imbalances or pathogens. To get ride of the symptoms, we must address the root cause of the problem.

The Functional Medicine provider, in a similar way to a detective, starts by looking for clues to eventually identify the underlying cause of the symptoms and address it.

Functional Medicine Certification was create for healthcare providers who are interested in improving their understanding of the triggers of chronic diseases and inflammatory conditions, as well as nutritional and herbal medicine and stress management and improve their clinical outcome.

The Certification of Completion is available to healthcare providers, such as acupuncturists, Chiropractors, Naturopaths, Nutritionists, Nurses, Nurse Practitioners, Medical Doctors, and Physical Therapists, who are interested in learning the science and clinical application of Functional Medicine in simple and organized modules.

There are 3 significant differences. between this program and others.

First, most Functional Medicine training programs require dozens of hours of review of physiology and the theoretical aspects of Functional Medicine before you actually get to learn clinical application. For clinicians (or anybody else who wants to apply functional medicine), it’s like having dinner with 5 hours of appetizers before you get to the main dish.

Our approach: We choose to give you the scientific background and focus majority of our time and resources in clinical application that you can use to help your patients right away.

Second, majority of these programs will also cost a significant amount of money, typically between $12,000 to $30,000, due to the length of the program, and because they separate and brand each section of Functional Medicine as a separate course. For example, separating environmental medicine, immune response, and detoxification into three separate courses allows you to charge thousands of dollars for each.

Our approach: Simple, transparent, and upfront. You get all the classes, to train you as a Functional Medicine provider, as a bundle to save you money.

Third, due to separation of each module and including so many review hour of research and physiology, as well as long lectures about the future of medicine and public health, majority of programs take months or years to complete. Often, by the time you are done with learning one part of Functional Medicine, such as Environmental medicine and detoxification, months go by before you learn how to apply it on you patients.

Our approach: Built for clinicians. Every part of functional medicine is described and reviewed with focus on clinical protocols you can use immediately.

Our presenters have been in the field of Functional and Integrative medicine for a long time and some still teach in other programs. This program is their way of sharing their clinical experience and for you to gain years of accumulated knowledge of what works and what doesn’t.

The training course is delivered completely online and there is no need to travel. While the course is delivered online, it has a very simple layout and there is no need to be tech savvy.

After you sign up you will receive instant access to the platform with all of the videos, quizzes, and handouts and clinical guides to download with a unique login and password just for you. We like to update the content when needed, so this allows you to login from any computer all around the world and receive the information at any time. The entire course is hosted on its own password­ protected website and you’ll receive weekly emails to keep you on track. interviews with expert

The course was created by Regain Health Science, a leader in healthcare education, and multiple providers and professors with years of clinical and teaching experience.

The Educational Director is Tal Cohen, DAOM, MS-HNFM. He is the author of the book ‘Treating Pain and Inflammation with Functional Medicine: A Complete Clinical Guide to Finding and Treating the Ten Triggers of Disease’ and ‘The Complete Guide to Removing Toxins & Improving Your Health.’

Tal has 16 years of clinical experience is holistic and alternative medicine in several countries and is the program director of A New Way Clinic, an integrative medicien clinic offering regenerative and Functional medicine in Portland Oregon.

He had clinical rotation in acupuncture, herbal medicine, and nutrition in Hangzhou Central Hospital (China) and Rehabilitation Department in Sourasky Medical Center (Israel). Tal received graduate level training in nutrition, holistic medicine, and herbal medicine from the Acupuncture & Integrative Medicine College (California), his Master of Science in Human Nutrition and Functional Medicine from University of Western States (Oregon), and a Doctorate in Acupuncture and Oriental Medicine from Oregon College of Oriental Medicine (Oregon).

Tal has years of experience teaching both patients and medical providers in Functional medicine, Integrative medicine, and Regenerative medicine conferences.

Each module takes about one to two hours and there are 16 modules (plus a few bonuses), plus short quizzes. It’s essentially depending on your pace of study, but most of our students were able to complete the course within a a few weeks even with a full time clinical practice.

This program provides the scientific background for Functional Medicine, but mostly focuses on clinical applications.

For anybody that is interested in focusing on studying the theoretical side of Functional Medicine or only a review of studies, I recommend looking into Functional medicine degree or other programs. The major disadvantage of doing other programs or a degree in Functional medicine is that it takes hundreds (or thousands) of hours and several years (about 3 to 4) to complete and have a very small of clinical application.


We are here to assist you if you have any technical issue. The platform is designed to provide you with 24/7 access from anywhere in the world and is based on educational platform with years of experience. However, if you need assistance, you can call or email us and we will be happy to assist.

It took a lot of time and resources to build each part of this course. From building, modifying, and presenting each module until it was perfect to investing dozens of hours of editing and programming to make sure that you’ll have a great experience.

Based on our existing members who have already joined and took the course, we think you are going to learn so much and love what we’ve created!

So, if you login to the course and do not like what you get, email us within 5 days of signing up and we will refund the whole course.

Simply put, we believe in what we created and we have seen how much it helped to educate doctors and healthcare providers. But we cannot do the discovery for you. We’ve done our part to create and continually improve this program in order to give you the tools to become a Functional medicine provider.

Again, with that being said, if you login to the course and do not like what you get, email us within 5 days of signing up to and we will provide you personal support and/or refund your purchase.

Therefore, after you complete the course, we will keep access available to you just in case you would like to review the lectures or clinical protocols again. All the clinical guides are downloadable and you can keep them on your computer for personal use.

We introduce new videos every week to help you start and improve your practice, get more clients, and increase revenue.
