Samantha Lander

Samantha Lander teaches functional diagnostics and peptide protocol support at Peptide University, focused on reading labs well before any peptide is chosen. Her Peptide University case study sessions walk practitioners through real functional workups: what the testing showed, what was addressed first, and how peptide protocols were layered onto foundational care. Practitioners work with her through Peptide University's live clinical classes, Inner Circle membership, and the Clinical Peptide Therapy Certification curriculum.

Samantha Lander is a St. Louis, Missouri native who built her career around personal training and functional lab-based nutrition coaching after an early path through collegiate athletics and the Los Angeles music industry. She graduated from the University of Michigan in 2003 with a degree in sports management, and her own account describes competing in synchronized swimming, water polo, field hockey and rowing, including serving as a coxswain for the university's crew program. Following graduation she spent time working in the Los Angeles music industry as a DJ and producer before returning to fitness and wellness work, eventually founding SeeFit Living, also styled SeeFit Personal Training and Functional Diagnostic Nutrition, in St. Louis.

Lander earned a personal training certification through NASM in 2008 and a certification through NESTA the same year. In 2010 she completed a Functional Diagnostic Nutrition (FDN) certification, along with Holistic Lifestyle Coach and Exercise Coach designations at Level 3 through the CHEK Institute. She later added a Functional Movement Screen certification in 2011, the Poliquin BioSignature Assessment, several integrative health certificates between 2017 and 2019, and an American Association of Drugless Practitioners designation in 2020. These credentials are self-reported on her own practice site, and none of them constitutes a state license.

It is important for prospective students and clients to understand precisely what the FDN-P credential is and is not. Functional Diagnostic Nutrition is a private, non-accredited certificate program operated by a company founded by Reed Davis and based in Henderson, Nevada, completed online over roughly four to eight months. An FDN-P is not a licensed healthcare provider, not a registered dietitian, and not a physician. FDN-Ps cannot diagnose disease, treat medical conditions, or prescribe medication, and are expected to refer clients with disease symptoms to licensed medical professionals. Samantha Lander is not a clinician and does not hold any medical, nursing, dietetic, or doctoral credential. Her own practice materials state this boundary directly: "Samantha does not medicate, she educates." Nothing on this page should be read as diagnosis, treatment, or a claim of clinical outcomes.

In her practice, Lander works with clients using the D.R.E.S.S. for Health Success framework taught by the Functional Diagnostic Nutrition program, an approach organized around diet, rest, exercise, stress reduction and supplementation, paired with functional lab panels covering areas such as food sensitivity, hormone and adrenal function, metabolic markers, gastrointestinal pathogens, heavy metals, and intestinal barrier health. She describes this as an educational, root-cause-oriented process rather than a diagnostic or treatment service, and her materials note that laboratory fees are billed separately from her coaching services.

Lander has also become a public voice on recovery from addiction, discussing her own experience with substance use, recovery, and rebuilding a career and health practice on podcasts including LAF Life and as a featured storyteller for Campfire. This part of her public work is self-disclosed and distinct from her functional nutrition practice, and it is not the basis of any clinical claim. She has discussed peptides, gut health, and nervous-system regulation as topics of personal and educational interest on podcast appearances such as Peptides for Women, but no claim of clinical outcome or treatment efficacy attaches to that discussion, and none should be inferred from it.

At Peptide University, Lander leads the class Functional Medicine Clinical Case Studies, described by Peptide University as monthly peer-to-peer case reviews for clinicians covering functional diagnostics, root-cause analysis, and peptide therapy as applied to real patient cases. She is a contributing author, one of roughly two dozen, to the multi-author anthology Dream Big Do Bigger: Build the Bridge Between Your Dreams and Reality, published by She Rises Studios. She has no peer-reviewed publications, no TEDx talk, and no academic, hospital, or licensing-board affiliation; her authority in this space is educational and experiential rather than clinical or research-based.
