Become an FDN Practitioner — The FDN Certification Course, Explained

By Self Growth Videos — built from FDN’s published course information and the public record of Jennifer Woodward, the FDN graduate whose career this guide follows. Self Growth Videos has not enrolled in the course and has no affiliate relationship with FDN at the time of writing; the links below are FDN’s official pages.

Why this guide follows Jennifer Woodward

Most certification guides are written in the abstract. This one follows a person, because Jennifer Woodward’s career is the clearest worked example of what the FDN path can become:

• Before: sales representative for a Fortune 500 pharmaceutical company, dealing with her own hormonal health crisis.
• May 2019: graduates from the FDN Certification Course.
• November 2019 – March 2020: FDN’s Director of Education.
• October 2020 – today: Executive Director of the AFDNP, the Association of Functional Diagnostic Nutrition Professionals — the FDN graduates’ own professional association. She also created and directed the FDN Business School.
• Since then: a Master of Science in Nutrition from Parker University (2020), a California practice focused on women over 40, a book (Easy Perimenopause, 2025), and a teaching platform — the Peptides for Women podcast and the Jennifer Woodward Nutrition channel — built on the credential. Watch the 25 episodes SGV distilled from her catalog.

That trajectory — student, educator, association head, practice owner — is why FDN uses stories like hers to sell the course. Here is the course itself, on FDN’s published facts.

What the FDN Certification Course is

The FDN Certification Course (Functional Diagnostic Nutrition) is a self-paced, fully online practitioner training. Its published structure:

• Format: online and self-paced; most students finish in 4–12 months, at roughly 150 hours of study.
• Mentorship: 12 one-on-one mentor sessions with experienced practitioners are built into the course.
• Assessment: an exam and competency checks gate the credential — it is not a pay-and-print certificate.
• Credential awarded: FDN-P (Functional Diagnostic Nutrition Practitioner). Per FDN, the credential carries eligibility for accreditation through bodies such as the AADP, AANWC, and AANWP.
• Who can enroll: health coaches, nutrition professionals, nurses, chiropractors, doctors, and fitness professionals — and career changers. No license is required.
• Method: training is organized around FDN’s own frameworks — D.R.E.S.S. for Health Success® and its Metabolic Chaos® model of dysfunction — and includes business training for building a practice, not just clinical content.

The five labs you run on yourself

The hands-on core of the course: trainees run FDN’s five core functional labs on themselves during training, and FDN says the lab kits are included in the tuition. FDN frames its lab work through its “H.I.D.D.E.N.” system — six stressor categories the labs are meant to surface:

• Hormone
• Immune
• Digestion
• Detoxification
• Energy production
• Nervous system balance

Learning to interpret real results — starting with your own — is the skill the credential is built around, according to FDN’s course materials.

The part that changes a practice: 70+ client labs

FDN’s central claim, and the reason practitioners choose it over cheaper certificates, is what happens after graduation: per FDN, graduates can order more than 70 functional labs for their clients through FDN’s Medical Director Program. That structure is FDN’s answer to the problem that stops most unlicensed coaches — they can learn lab interpretation, but they cannot legally order labs. The Medical Director Program is how FDN says its graduates offer lab-based work without holding a medical license themselves.

What it costs

• Published price: $11,497. FDN’s own comparison pages show the course priced up to $12,997 depending on the promotion in effect — treat $11,497 as the standard published figure and confirm the live price on FDN’s site.
• Payment plans from $590/month, per FDN’s published terms.
• The five trainee lab kits are included, per FDN — a real line item to compare against programs that bill labs separately.

There is also a free on-ramp: FDN offers a try-the-course-free door with sample lessons, so the curriculum can be inspected before any enrollment decision.

FDN vs. a generic health-coaching certificate

FDN publishes its own comparison pages making this argument; the FDN column below reflects FDN’s published course structure, and the generic column describes the typical short-course market. Individual programs vary — check any program’s syllabus before enrolling.

After FDN: the peptides specialty

Woodward’s own next step after the FDN credential was specialization. With Tina Haupert — a fellow FDN-P who appears across her episodes — she co-teaches Peptides for Practitioners, a five-module certification for practitioners adding peptides to their work (NASM 0.6 CEUs). It lists at $497, was $197 at last check, and all sales are final. It is her course, sold on her terms — we link the official page only.

Peptides also sit inside a live policy fight, and practitioners building on them should know it: which peptides can be compounded, prescribed, and sold in the US is being contested at the FDA right now. Our sister publication tracks that chronicle — see RFK Team Report’s “Peptides: The Access Fight” coverage for the access and compounding-policy record.

Her book

Woodward’s consumer-facing work is collected in Easy Perimenopause: The Essential Guide to Modern Midlife (Finesse Literary Press, February 2025) — the perimenopause guide she wrote for the women her practice serves. It is listed in the books band on her SGV profile.
