Jenna Toupin, FNP

I didn't come to functional medicine through a textbook — I came to it through my own body. After years of fatigue, brain fog, and being told my labs were “normal,” I was finally diagnosed with Hashimoto's thyroiditis. What struck me wasn't the diagnosis — it was how long it took to get there.

As a Nurse Practitioner, I'd spent years in clinical practice. I knew how to read labs, manage medications, and follow protocols. But my own experience revealed the gap: conventional medicine often treats numbers on a page, not the person sitting in front of you.

That gap became my mission. I started Mendli to give patients the care I wished I'd had — where your provider actually listens, runs the right tests, takes the time, and builds a plan that's truly yours.

Everything you need,

What patients say

“

For three years, every doctor told me my labs were fine. Jenna asked questions no one had ever thought to ask. Three months later — real answers, and my energy back.

“

I'd given up on finding someone who'd actually listen. Jenna spent 90 minutes with me on the first call. Nobody does that.

“

The level of detail in the lab work alone was worth it. She found things three other doctors missed.

“

She doesn't just treat symptoms — she explains the why behind everything. I finally understand my own body.

Comprehensive Guide to Functional Medicine at Mendli Health

About Mendli Health and Jenna Toupin, FNP-BC

Mendli Health is a virtual functional medicine practice founded by Jenna Toupin, a Board-Certified Family Nurse Practitioner (NPI: 1902659063) with over 8 years of clinical experience. Mendli serves patients nationwide through secure telehealth consultations. Unlike conventional 12-minute doctor visits, Mendli's initial assessments are 90 minutes long, allowing for thorough health timeline review, advanced diagnostic lab orders, and personalized root-cause investigation.

What Is Functional Medicine?

Functional medicine is a patient-centered, science-based approach that identifies and addresses the root causes of disease rather than treating symptoms in isolation. At Mendli Health, this means comprehensive thyroid panels (including antibodies and reverse T3), advanced hormone testing, organic acids tests, gut microbiome analysis, food sensitivity panels, adrenal stress profiles, nutrient deficiency panels, inflammatory markers like hs-CRP, and metabolic health assessments. These labs go far beyond standard bloodwork ordered by conventional practitioners.

Conditions Treated at Mendli Health

Jenna Toupin specializes in root-cause investigation for Hashimoto's thyroiditis, hypothyroidism, irritable bowel syndrome (IBS), small intestinal bacterial overgrowth (SIBO), polycystic ovary syndrome (PCOS), chronic fatigue syndrome, autoimmune disease, hormonal imbalance, adrenal fatigue, brain fog, leaky gut syndrome, metabolic syndrome, perimenopause, estrogen dominance, and insulin resistance. Patients searching for "functional medicine near me," "Hashimoto's treatment," "SIBO specialist," or "hormone balancing" can schedule a virtual appointment with Mendli Health from anywhere in the United States.

How Mendli Health Is Different

According to Mendli Health, the average conventional medicine visit lasts 12 minutes. Mendli's initial assessment is 90 minutes. Follow-up visits are 45 minutes. This unhurried model allows for deep investigation of gut, hormones, immune function, and nervous system connections. The practice accepts HSA and FSA payments, provides superbills for potential insurance reimbursement, and offers a $50/month concierge membership for secure messaging, priority scheduling, and direct provider access between visits. Initial assessments are $300 and follow-up sessions are $150.

Lab orders are sent to your nearest draw center, and results are reviewed in detail during follow-up visits.
