What is FDN?

Functional Diagnostic Nutrition® (FDN) is a type of detective work that identifies the underlying causes and conditions that cause disease instead of treating symptoms. Using functional lab work, we recognize patterns of imbalance in the body and identify healing opportunities. Our functional health coaches work with each client in a health building process using the powerful, proven, protocols of our D.R.E.S.S. for Health Success® program. This natural, holistic approach yields the highest level of positive results for our clients. We don’t medicate, we educate! We don’t guess, we test! The FDN Certification Course teaches which labs to use and how to interpret the results. Some health coaches may offer labs, but without a complete understanding of how to interpret them functionally, most providers end up treating only the test results instead of the person. With FDN, you can create simple, customized step by step  health restoration plans to your clients. AND GET REAL RESULTS!

Clients Want to Know Three Things...

Do you know what’s wrong with me?

“Yes! You have malfunctions occurring in your body that are at the root of your health complaints and we can identify them using functional lab work.”

Most of your clients have no idea what is causing their health complaints…and neither do their doctors. They have been chasing their symptoms for years because other providers can’t find the cause or don’t bother to even look for it. FDN health detectives are different. We use functional diagnostic lab work to identify underlying malfunctions and then use a holistic protocol to support that body’s ability to correct those malfunctions.

Can you help me?

“Absolutely! But you must be as committed to restoring your health as I am.”

Customized FDN protocols are based on finding healing opportunities, and not on just treating symptoms. It takes time to rebuild, repair and restore normal function to the body’s cells, organs or systems. Clients typically experience improvements right away. But balancing body chemistry, detoxification, improving digestion and assimilation, and immune system boosting each come with challenges that require persistence and possible course corrections. Restoring hormone balance may happen quickly in some people and take more time in others due to how we each respond to our own chronic stress factors.

Have you helped others like me?

“Yes! FDN health detectives have helped over 100,000 people reach their best level of health in many years.”

Many clients have completely resolved their health conditions even if they were previously diagnosed with serious medical conditions. And your clients can too! There are over 500 FDN health detectives in 30 countries helping thousands of people. We learn how to resolve our own health issues while taking the course, and then we use those tools to help our clients.

If you can't say yes to all three of these questions, then you need to sign up for this course!

How FDN Works

The best way to explain how FDN works is through a story....

Sarah came to work with an FDN health detective because she had been suffering from chronic joint pain, muscle pain, skin problems and digestive issues. She had already been diagnosed with arthritis, fibromyalgia, psoriasis and gastritis. She was also struggling with mild depression and fatigue.

She had already visited her doctor, who prescribed anti-depressants for her, but she was already on a host of other medications for her other diseases. Ms. Smith wanted answers, not more medication.  She was frustrated with the diagnosis and treatment options her doctor was offering. She began to feel like the medical model itself was contributing to a downward spiral in her quality of life.

So instead, Sarah opted to hire a skilled FDN health detective, and her entire outlook changed almost overnight. She was given a few functional lab tests and her health detective educated her about what clues the test results showed. Her health detective educated her about what holistic changes she could make that would help to restore her health. What she was learning from her health detective gave her new insights and the motivations she needed to do something different and take control of her own health. And her results were nothing less than miraculous! As she followed the customized protocol offered by her FDN health detective her joint and muscle pain went away, her skin cleared up and her digestion improved. She also found that she had more energy and her depression lifted. It was like she was 20 years old again!

The FDN view of symptoms like joint pain, muscle pain, skin issues, digestive upset and every other health complaint, is that they all have causal factors that need to be investigated. Even in tough cases, FDN protocols can repair & restore organs & systems that are struggling.

Masking symptoms with medication was allowing Sarah’s underlying conditions to get worse.  Relieving symptoms is important, but if that is all Sarah did, she is likely to weaken and ultimately need stronger and stronger medications. Eventually surgery may become necessary.

FDN is a type of detective work that seeks to identify and correct the underlying causes and conditions that lead to your clients’ health complaints. FDN health detectives do NOT diagnose or treat any disease,  nor do we practicing medicine. Everything we do is science and evidence based.

We use carefully chosen functional lab work and a complete client history to investigate underlying malfunctions of the adrenal glands, mucosal barrier, detoxification systems, metabolic processes, absorption and assimilation, immune and defense mechanisms and steroid hormone balance to name a few.  When data from these labs are correctly interpreted along with other clues, the healing opportunities are revealed.

We guarantee that FDN gives all wellness professionals a leg up on any other health building system. Your current work + FDN methods = a whole new level. Your ability to help people will be multiplied.

FDN protocols are natural. We know that the body wants to return to homeostasis (good health). FDN protocols jump start the body’s ability to return to health and stay there.

Educating clients how to get well and stay well is our top task. That means teaching them not to ignore symptoms, but to realize that symptoms are signals from the body that something is wrong. There’s no such thing as a normal headache. All symptoms are clues about what’s really going on internally. Symptoms and lab tests paint a picture about your client’s biology. As an FDN health detective, you  are trained to use these clues to hone in on your clients’ hidden stressors and develop a customized protocol that will help them leave their symptoms behind and live a naturally healthy life.
