Nutritionist & Peptide Therapy Denver
Functional Nutrition & Longevity Coach
Optimize Your Everything.
This is where high performers come to look, think, and feel their best. Close the gap between where you are and where you know you could be.
Is this Functional Nutrition support right for you?
My clients are executives, entrepreneurs, and athletes who want one expert, root cause answers, and faster results. Some are navigating perimenopause. Some are optimizing energy, mental clarity, and performance. Some are building a longevity strategy. Some are addressing a specific condition like Hashimotos or SIBO that nobody has been able to fully resolve.
What they have in common: they take their health seriously and they expect the same in return.
We are concierge, specialized, and selective. We work with a limited number of clients. We go deep. We get results.

Why does looking at the root cause create faster results?
Most people arrive at Luxia Coaching having already done a lot of the right things. They’ve worked with good practitioners, run the standard labs, tried the protocols. And they’re still not where they want to be — because nobody has looked at all of it together and asked the right question:
Functional nutrition therapy, peptide therapy, hormone optimization, longevity protocols, and mindset coaching aren’t separate services at Luxia. They are tools I use in combination because the body is one system and that’s exactly how it needs to be treated. When you work with someone who understands all of those levers and knows how to pull the right ones in the right order, you stop spinning your wheels and start getting answers and faster results.

Meet Rachel Leigh
Founder and CEO, Luxia Coaching
I’m Rachel Leigh — nutritionist and longevity coach based in Denver and working with executives, entrepreneurs, and athletes nationwide. I’ve been studying health and human performance since college — 30 years of focused, dedicated study that became a clinical practice, hundreds of client relationships, and a way of working my clients describe as unlike anything they’ve experienced before.
I am a board-certified health and wellness coach, certified nutrition therapist, and ICF Professional Certified Coach with advanced training in functional health, lifestyle medicine, and peptide therapy. The body is one integrated system. Your nutrition, hormones, gut, stress response, sleep, mindset — everything connects and everything influences everything else. When you have the clinical depth to read that full picture accurately and quickly, the path forward becomes clear in a way it never has before.
Clients call me a unicorn. What they mean is: I see the intricacies, the whole ecosystem, the whole person as one entity — and I get to the root of it fast.
Our Clients Are Thriving At Companies Including

Rachel is a true partner in life, and working with her has easily been the best decision I've made
Want the most caring and constructive kick in the tush you’ll ever receive? Look no further than coaching with Rachel. She will partner with you in every way to dig deep and uncover what you really want out of life and devise realistic ways to support you in achieving it. Best of all, she does this with her signature humor and no-nonsense delivery, living the lesson that we should never work so hard that we lose the ability to laugh at ourselves while discovering who we’re truly meant to be. She is a true partner in life, and working with her has easily been the best decision I’ve made when I chose to begin actively investing in myself.

The constant pressure was gone. Rachel equipped me with tools to manage stress and cultivate a more positive mindset. I finally felt like I was in control. The best part? With a more focused and organized business, my profits soared. Rachel’s guidance helped me identify areas for cost-saving and streamline operations for maximum financial gain.

One of the best investments in myself I have made in a long time.
Rachel is amazing! The work with her is beyond nutrition – it is thinking about your lifestyle and learning self-care. The steps that we have taken to improve my nutrition have been easier than I imagined and incremental so that I could take them on. Her connections to resources to support your journey are equally life changing and overall, she is just a lovely human. One of the best investments in myself I have made in a long time.

Rachel is a life changer, so quit reading reviews and give her a call!!!
Rachel is the best! She helped me sort out my nutrition needs for several long-distance races, tackling problems as they inevitable pop up during intense training. More importantly, she helped me solve an auto-immune issue that had been plaguing me my entire life. Now, my life is wonderful with only a few changes to my diet. Rachel is a life changer, so quit reading reviews and give her a call!!!

Frequently Asked Questions About Functional Nutrition and Luxia Coaching
Is everything online?
How is working with Rachel different from seeing a functional medicine doctor?
How do peptides work, and are they safe?
Peptides are short chains of amino acids that act as precise signaling molecules in the body — they communicate with specific biological systems to support functions like tissue repair, hormone optimization, metabolic health, cognitive performance, and healthy aging. When used correctly, with the right protocols and proper medical oversight, they are well-tolerated and highly effective. All peptide protocols through Luxia Coaching are prescribed and managed exclusively by EllieMD, our medical director, using human grade peptides — the highest clinical standard available. We work with you on everything surrounding the protocol to ensure it is integrated into your complete health strategy.
