Our Mission
For far too long, hormones have been saddled with an unfair reputation.
Acne? Hormonal. Mood swings? Hormones strike again. Weight gain? Well, you get the picture.
Sure, these symptoms may arise when hormones fall out of balance. But what if we told you that, under the right conditions, hormones can also bring forth the best version of you?
We’re determined to tell that side of the story.
We believe hormones are a biological masterpiece. Every day, dozens of these chemical messengers unite with your cells, regulating your moods, metabolism, energy levels, and more.
Healthy hormones are key if you want to move through life with energy, strength, and high spirits. They deserve to be celebrated, yet that rarely happens.
Our purpose is simple: We want to give women the tools to honor and care for their hormones every day.
Knowell’s daily supplement gives you the nutritional foundation for hormone balance, while our content library helps you become the authority on your own hormonal health.
Knowledge is the first step to wellbeing; nourishment comes next. We’re here to be a trusted friend on both fronts, for all women who want to work with their hormones, not fight against them.
This We Promise You
Our daily supplement helps women get the most out of their healthy lifestyles by supporting optimal hormone balance.
We’re committed to creating the purest, most effective supplements possible—and we’ll always be transparent about what’s inside each bottle.
We’re passionate about science and ancient medicine, and we share our wisdom so women can own their hormonal health.
Our products and platform serve women of all ages, during all stages of life—from the teen years through to postmenopause and all in between.

I became a nutritionist out of a desire to help women live happier, healthier lifestyles. Working in private practice in New York City, I listened to so many women describe their frustrations and challenges—symptoms they couldn’t make sense of and results they weren’t reaching in spite of their best efforts.
I was also surprised to observe that many women were woefully undereducated about the importance of hormone health, reproductive function, and how these things impact overall health..

I became a nutritionist out of a desire to help women live happier, healthier lifestyles. Working in private practice in New York City, I listened to so many women describe their frustrations and challenges—symptoms they couldn’t make sense of and results they weren’t reaching in spite of their best efforts.
I was also surprised to observe that many women were woefully undereducated about the importance of hormone health, reproductive function, and how these things impact overall health. As a health professional, I sympathized with the fact that they couldn’t find evidence-based resources that could speak to them about hormonal health in a relatable way. I wanted to do something about this disconnect.
Besides my formal education in clinical nutrition, my knowledge of hormonal imbalance came from intimate and personal experiences. I‘ve known I wanted to be a mother for as long as I can remember, but my husband and I struggled for six years with infertility. Using two different clinics, I underwent four rounds of IVF and suffered five miscarriages. Over that time, my physical health completely changed—I went from having “regular” cycles to having completely dysfunctional and unpredictable ones. As far as mental health goes, I was a basket case.
To gain control of my health and reestablish balance, I dove head first into the scientific literature as well as acupuncture and other traditional practices. My nutritionist’s brain told me to research the targeted nutrition that endocrine organs need to thrive. The part of me that admires Eastern practices prompted a look into traditional plants. As a result, my daily routine entailed a daunting amount of powders, capsules, and extracts—and a lot of work and expense. It all helped me feel better, but it was far from easy.
Those two lightbulb moments—my desire to create a reliable women’s health platform and a convenient nutrition supplement for hormone balance—became a legitimate possibility when I met my cofounder, Pete! He expressed immense compassion for my story and encouraged me to think big. All the things that Gaga said about Bradley Cooper, I say about Pete. As a marketing pro, he showed me how we could make our ideas come to life. And thus, Knowell was born. We can’t wait to offer you the best information and products to transform your hormonal health—from the bottom of our hearts into your homes.

I’ve been asked the same question a hundred times since developing Knowell: “Why is a guy interested in women's hormone health?” That’s a real shame, considering we’re referring to the welfare of half the population. Admittedly, women's health wasn't exactly a common topic of conversation growing up. At school and beyond, health ed was split by gender—your own inner workings were supposedly all you needed to worry about. However, knowing what I know today, only being told half of the story is a flawed approach.
Growing up, I was lucky enough to be surrounded by strong women. However, it wasn’t until first meeting my wonderful co-founder, Katie, that my interest in women's health blossomed..

Growing up, I was lucky enough to be surrounded by strong women. However, it wasn’t until first meeting my wonderful co-founder, Katie, that my interest in women's health blossomed. A chance meeting led to a fast friendship, and as we spent more time together, she shared her story about her struggles with hormones and overall health. It all became so clear why helping others as a nutritionist was so perfect for her.
Katie had dedicated much of her career to decoding hormonal health, and I quickly received a lesson in hormones 101. As I started to learn more about how our hormones affect every aspect of our lives, I became pretty dismayed at how this area of health had become so stigmatized. Why was there so little education around something that impacts us so profoundly on a daily basis?
As I broached the topic with friends, I started to hear of the many struggles they shared in trying to maintain hormonal balance. Some were dealing with the effects of PCOS, while others were managing thyroid or mental health issues linked to hormones. The worst part of it all? Everyone echoed the lack of resources and support around hormone issues.
What came next was a bit of an obsession. There had to be a better way—a way to shine a light on the importance of overall hormone health for all women. As Katie once said, “I truly believe that hormone health is the cornerstone to overall wellness.” That is why I’m so devoted to this journey.
