Inside Health · Functional Healing for Women · 100% Virtual

Your Labs Say Normal. Your Body Says Otherwise.

For the woman who is functioning but not thriving, start with the same evaluation Dr. Lauren and Dr. David use with every new client, then let them tell you exactly what’s next.

Two consultations. One blood draw. One clear next step.

Two practitioners. One shared framework. Your care doesn’t change hands when it’s inconvenient for us.

You’re not imagining it.

You’ve done the sleep routines. The supplements. The eat clean, move more, drink more water. And you still wake up tired in a way rest doesn’t touch, still catch your reflection and wonder when you started looking like this, still sit across from a doctor who tells you your labs are normal while your body tells you otherwise.

You’re not imagining it, and you’re not lazy. You’re in the middle of one of the most complex hormonal transitions of your life, and most of conventional medicine was never built to see it.

This is what Dr. Lauren and Dr. David built Inside Health for. Not to hand you another lab report you can’t read. To find out what’s actually driving the way you feel, and fix that.

Why Dr. Lauren and Dr. David built Inside Health.

In their early 20s, Dr. Lauren and Dr. David were sick, overweight, and stuck cycling through medications that never solved anything, only added another prescription to the pile.

Every doctor visit ended the same way. More pills, no real answers. Eventually they stopped waiting for a medical system that couldn’t explain what was happening to them.

What they built instead became the IGNITE Method, six steps that trace a symptom back to its root instead of managing it forever.

Today that same framework runs a fully virtual practice, so the care that changed their lives can reach a woman anywhere, not just the ones who can drive to Loveland, Colorado.

They didn’t set out to build a wellness brand. They set out to stop feeling like this, and then to make sure no one had to feel like this alone.

"Dr. Lauren Kolowski is amazing doctor / Nutrition Response Therapist (NRT)! I’ve been seeing her for over ten years now! She has helped with with numerous ailments, ranging from minor to very serious, some of which allopathic medicine would have gone a more invasive route with little or no results. Dr. Lauren is extremely competent and is very quick. I truly believe that had I not seen Dr. Lauren, my health would have taken a drastically different turn. "

"I love working with Dr Lauren!! I am doing it to maintain my good health! Initially she helped me resolve my issues and soon I realized I felt better and had much more energy! I didn’t ever realize that I didn’t feel great - until I DID start feeling great! Now I’m able to pinpoint when something is off right away and we get it taken care of before it becomes an issue. I have people tell me that “you never age” and that I look great - and it’s thanks to Dr Lauren’s help! I’m a believer that taking care of my health now will benefit me in the years to come! And I’m doing it with Dr Lauren right beside me!!"

"I’ve been seeing Dr. Lauren virtually since 2021. She has checked myself, my husband and my 2 children for the last 3 years and we have noticed such a difference in our health. We have all experienced better sleep, improvement in digestion and we don’t get sick as often- even in the winter months. Dr. Lauren is so helpful and knowledgeable about the REAL underlying causes of disease in the body. Being healthy takes work and a lot of it, but having Dr. Lauren on our team has made a world of difference. We truly believe her care has provided our family with better health now and in our future. Thank you Dr. Lauren!!"

Your MVX+ Evaluation

Two 30-minute consultations and a functional blood draw with your Inside Health practitioner team, the same starting point every Inside Health client goes through. You’ll leave with a real answer for what’s driving the way you feel, and a clear recommendation for what’s next, whether that’s a specific protocol, ongoing 1:1 care, or IGNITE365.

From there, Dr. Lauren and Dr. David tell you exactly what’s next.

Hormone Reset Masterclass

Free · monthly · live

If you’re not ready to book your evaluation yet, start here. A live class with Dr. Lauren on the hormone patterns behind fatigue, weight changes, and feeling like a stranger in your own body.

Ongoing 1:1 Care

By recommendation, after your MVX+ evaluation

For the client who needs consistent, hands-on care. Weekly 10-minute check-ins with Dr. Lauren or your dedicated practitioner. Built for the client who does better with steady contact, not a once-a-quarter check-in.

IGNITE365

Pricing shared on your evaluation call

For the client who wants root-cause care alongside a community of women doing the same work. Every plan looks different, so we walk through fit and investment together, not on a checkout page.

The IGNITE Method

The IGNITE Method is Inside Health’s six-part root-cause framework for treating hormone imbalance and fatigue in women, built from Dr. Lauren and Dr. David’s own recovery and 29 years of combined clinical practice.

Free · monthly · live with Dr. Lauren

You don’t need another lab report telling you you’re fine.

You need someone to find out why you don’t feel fine.

That’s what Dr. Lauren and Dr. David built Inside Health to do.
