I Hear You
Does this sound like you?
These are the things my patients tell me most often. If you see yourself here, you’re in the right place.
You’re not imagining it, and you’re not alone.
Your symptoms are real. They are your body’s way of telling you something needs attention. I take the time to listen to your whole story, find the root cause, and build a plan to help you feel like yourself again.
Stop surviving and start thriving!
Root Cause Healing
One approach. A plan that’s only yours.
I don’t sort you into a service or hand you a protocol off the shelf. Your body is one connected system — your hormones, gut, metabolism, sleep and stress all talk to each other. So I look at all of it, find what’s actually driving how you feel, and build a plan around you.
That plan might include hormone support, peptide therapy, gut healing, or something else entirely. It depends on your story, your labs, and your goals — not a menu.
“All disease begins in the gut.”
— attributed to Hippocrates
Personalized to You
What your plan may include
These are tools, not packages. Most plans use a few of them. No two look the same.
Hormone support
Thyroid, adrenal, blood sugar and sex hormones — balanced for your body and your season of life.
Peptide therapy
Medically supervised peptides, when they fit your goals and your health history.
Gut healing
Digestion, food sensitivities, and the gut’s role in energy, mood, skin and immunity.
Metabolism & weight
Sustainable support that works with your hormones and blood sugar — not against them.
Targeted lab work
Testing chosen for your symptoms, so we’re working from answers instead of guesses.
Nutrition, sleep & lifestyle
Food, sleep, stress and movement changes that fit the life you actually live.
Supplements
Professional-grade supplements, only when they serve a clear purpose in your plan.
I make every recommendation myself, based on your history, labs and goals.
How It Comes Together
Built around you, step by step
1. I listen
An unrushed conversation about your whole story — symptoms, history, lifestyle, and what you want to feel like again.
2. I look deeper
Targeted labs where appropriate, so I can see what’s really going on beneath the “normal” results.
3. I personalize & adjust
A plan made for you — then refined at follow-ups as your body responds. You’re never doing this alone.
Your Practitioner
Meet Kristin
Kristin Hostetter, MSN, RN, FNP-BC, is a board-certified Family Nurse Practitioner who became a functional medicine practitioner the honest way: as a patient whose symptoms conventional care never quite explained.
Now she gives her patients what she went searching for: unrushed visits, real listening, and a plan built around the whole person. Read her story →
The Power of Functional Medicine
Uncovering the root cause
Instead of only managing symptoms, I look at the whole picture — your history, lifestyle, and targeted lab work where appropriate — and build a personalized plan that fits your real life, from the food on your counter to the sleep you’re not getting.
Care Wherever You Are
Visits built around your life
Meet with me from wherever you’re comfortable. Follow-up visits track your progress and adjust your plan as your body responds — you’re never doing this alone. Telehealth visits are currently available for patients in New York and Florida — with licensure in additional states on the way — and health coaching programs are available nationwide.
“I built this practice on the kind of care I spent years searching for — unrushed, curious, and focused on the whole person.”
— Kristin Hostetter, MSN, RN, FNP-BC

Raeleen’s reset
- Started March 2026
Raeleen came to me after weeks of searching for a practitioner who would really listen. We focused on healing her gut first, then built her plan from there.
“I highly recommend Regen Holistics. After searching for weeks, I found someone that matched what I was looking for. Kristin is highly knowledgeable, skilled and patient but most importantly she really listens to me. My weight is down, hormones balanced, energy has increased and I’m thrilled! Regen Holistics has been the best decision I’ve made in a long time.”

Have been working with Kristin for almost 3 months. I was making zero progress with my medical issues with traditional medicine and only gaining weight and slowing down. With her help (and a lot of patience!) energy is coming back and I’ve lost 30 pounds! Seems like she is always there and answers messages very promptly, even when you don’t expect an answer for a few days. Highly recommended!!

Amazing! I’ve been able to fine tune my health needs thanks to Kristin. I have improved energy and ditched the fatigue thanks to a plan that is custom tailored for my body’s needs through supplemental vitamins. She is a gem to work with and truly cares about her patient’s well being!

Regen Holistics has shown me what really was happening in my body and what I needed to focus on to feel better. Kristin does a fantastic job explaining how functional medicine works and guiding me through the phases. She’s always there to answer any questions I have. I am so glad I reached out and started this journey!
