the bioindividual
approach to health


an advocate for optimal health.


Welcome. I’m Kristine Mahan, MNT. Function of Well Nutrition is a private practice in Denver, Colorado. As a functional nutritionist, I’m here to meet you where you’re at and advocate for your optimal health. I find mission in helping people overcome health challenges to feel well because I have been on the other side.

I spent many of my young years sick and was left hanging to find my own healing by the paradigm of conventional medicine. Through the principles and application of functional health care, I healed myself. As I found out the hard way for myself, a nutrient-dense diet, proper supplementation, and attention to the mind-body connection are keys to vitality.

Together, we’ll figure out your unexplained symptoms by getting to their root cause. We’ll address your health concerns by looking at the body as a whole - everything is connected. We’ll take proactive steps to manage your health and save money in the longterm on prescriptions, unnecessary testing, and surgeries.



services to support


free intro calls

15 minute phone call for you to tell me your goals, ask me questions, and hear about my training and philosophy. This call is a great way to gauge how we will work together.



A 90 minute session for people new to Function of Well Nutrition. We will discuss your intake forms, lab work, and health history during this time. Throughout the session we will craft a plan for your health goals in the long haul. This can include dietary changes, personalized meal plans, supplement protocols, and ordering further testing.


nutrition protocol meetings

Protocol meetings allot 60 minutes to implement your personalized treatment plan after our initial consultation. This is a full walkthrough of what to eat, when to take supplements, lifestyle modifications, and most importantly understanding why.


check-in meetings

Quick, 20 minute visits or calls to modify a protocol as needed or for fast question support. Think questions like remedies for the common cold, supplement concerns, eating updates, suggestions for better sleep, etc.

intro package for
optimal health


This welcome package includes three sessions together and saves $25 from purchasing your Initial Consultation and two Update Meetings individually. Most clients need two to four update meetings to learn and receive support in incorporating eating and lifestyle change. If I suggest at the initial consult for clients to have further labs done, the following update meetings create a well-rounded picture of health to investigate in further update meetings.

This is an excellent way to invest in yourself, because health in the long haul is wealth. Feel good and save money.
